To date steel pipe diameter tables are relevant for the reason that pipes made of different types of plastic and metal are used in almost all areas of construction. In order to be able to easily understand this variety of material and learn how to combine them, regulatory documents have been developed, such as tables of steel pipe diameters and their correspondence to polymer pipes. You can use a pipe calculator to calculate pipe weight or pipe length.

Table of diameters of steel and polymer pipes.

Outside diameter (Dh), pipes, in mm according to GOST and DIN / EN
Conditional (Dy) pipes,	pipe threads (G), inches	Outer pipe diameter D, mm
			Steel pipes water and gas pipelines	Steel electrowelded and seamless	Polymer PE, PP, PVC

Nominal diameter(Dy, Dy) is the nominal size (in millimeters) of the inside diameter of the pipe or its rounded value, in inches.

Conditional pass represents the rounded nominal bore size. It is always rounded up only. The value of the nominal diameter of steel pipes is determined by GOST 355-52.

Symbols and GOSTs:

• DIN / EN - the main European assortment for steel pipes according to DIN2448 / DIN2458
• Steel pipes for water and gas supply - GOST 3262-75
• Electric-welded steel pipes - GOST 10704-91
• Seamless steel pipes GOST 8734-75 GOST 8732-78 and GOST 8731-74 (from 20 to 530 mm).

Classification of steel pipes by outer diameter (Dн).

Small outer diameter steel pipes used for the construction of plumbing systems in apartments, houses and other premises.

Average diameter steel pipes It is used for the construction of urban water pipelines, as well as in industrial systems for collecting crude oil.

Large diameter steel pipes necessary for the construction of trunk gas and oil pipelines.

Internal pipe diameter standard.

There is a standard for the inner diameter of pipes, which is accepted in most countries of the world. Internal diameter of pipes, measured in millimeters. The following are the most common internal pipe diameters:

• 200, etc.

Inner diameter of steel pipes denoted by (Dvn). There is also a certain standard for the diameter of pipes, it is designated by the term "nominal bore (diameter)". It is designated Dу.

Inner pipe diameter can be calculated using the following formula: Dvn = Dn - 2S.

Conversion tables from inch to metric. Thread size: table of metric and inch threads

The process of selecting the required cross-sectional dimensions of threads, cables and pipes is often time-consuming. In addition to the fact that it is necessary to select the appropriate dimensions, taking into account the parameters of the equipment, the customer has to independently convert the data into suitable units of measurement. This process is time-consuming.

We simplify this task as we offer you to use ready-made translation tables. On the page of our site you will find tables that will help you easily select the necessary threads for inch pipes, copper and aluminum conductors of wires and cables. Also, you can use the table for converting inch sizes to metric, thereby accurately calculate the required section dimensions.

Unfortunately, most equipment manufacturers leave the customer alone with the calculations. Therefore, a person has to independently search the Internet for translation tables in order to select the optimal sizes of wire cross-sections and pipe diameters.

We value the time of our customers, providing everyone with the opportunity to use ready-made solutions. Our tables have converted standard sizes from inches to millimeters.

On this page you will also find translations of the main energy units and pressure units, therefore, you can choose the right refrigeration equipment, taking into account the individual conditions of placement and modes of operation of the units.

In their shape, pipes can be not only round, but also oval, rectangular, square. Despite such a variety in cross-sectional shape, all pipes have basically two types of parameters: technical and geometric. The geometric dimensions of pipes are represented by characteristics such as outside diameter, wall thickness or the ratio of outside and inside diameters, and length. , that is, the dimensions of the pipes are standardized by state standards (GOSTs). Different GOSTs are developed for pipes not only with different manufacturing methods, but also for different materials used in the production of pipes. In the Russian market, it is generally accepted to indicate pipe dimensions in mm (millimeters), but you can also find pipe dimensions in inches. The latter are most often indicated for imported pipes. The length of rolled pipes is measured in meters as standard.

The most common and popular are the following pipe sizes (diameter from larger to smaller): 1420, 1220, 1020, 920, 820, 720, 530, 426, 377, 325, 273, 219, 159. This rolled product refers to pipes of large and medium diameter. Smaller diameters are much less in demand on the market, so, of course, you can find them, but you will have to try. On the manufacturer's website there will definitely be a table of pipe sizes that the given enterprise manufactures. Usually, any manufacturer tries to cover as wide a range of pipe sizes as possible, since nowadays the market for this type of rolled products is very wide.

Until recently, Russian production did not produce seamless pipes with a diameter of more than 426 mm. But electrowelded covers almost the entire range. Spiral welded pipes can have a diameter greater than 1420, but less than 159 - not available. With longitudinal seam pipes, things are different. According to GOST, the smallest diameter of a longitudinal welded pipe is 8 mm, and the largest is 1420 mm. This is due to the fact that spiral and longitudinal welded pipes have a different manufacturing method, although both of them belong to welded pipes.

Pipe sizes are not limited to one diameter. Wall thickness is also one of the important technical indicators. Moreover, the diameter directly affects the size of the pipes, such as the wall thickness. The larger diameter allows the production of pipes with a wider range of wall thicknesses. For example, if the dimensions of longitudinal metal pipes (or rather, their diameter) are 530 cm, then the wall thickness can vary from 5 to 24 mm. The outer transverse dimensions of longitudinal steel pipes of 1020 mm make it possible to manufacture them with a wall thickness of 8 mm to 32 mm. The most popular are for pipes, for example, with a diameter of 530 mm, such wall thicknesses as 7, 8, 9 and 10 mm. For a pipe with a diameter of 1020 mm, the most common thicknesses are 10, 11, 12, and also 14 mm.

It is interesting that the dimensions of GOST pipes allow manufacturers to violate certain limits. In particular, for a longitudinal welded pipe with a diameter of 1020 mm, the deviation of the wall thickness can reach almost 1 mm. More precisely - 0.8 mm, both in the direction of greater and in the direction of lesser thickness. And since the assortment of pipes is determined with a step of 1 mm in thickness, this value is quite significant. For example, when buying a pipe with a thickness of 11 mm, do not be surprised that when measured directly, it turns out to be a pipe with walls of 10 or 12 mm. This aspect is very important when buying pipes, since the weight of the rolled product depends on the size of the pipes, such as the wall thickness. More weight - more price. Why is it customary to indicate weight, not footage? Because the cost of a pipe mainly depends on raw materials (the so-called price-forming raw material component).

Of course, weighing a pipe is too troublesome. Therefore, when calculating the price, the theoretical weight is taken into account, which is calculated by the formula: weight of 1 running meter = 0.02466 * wall thickness * (diameter-wall thickness). The wall thickness is taken in millimeters. In practice, the calculation is carried out as follows: the buyer measures the thickness of the pipes with a micrometer in order to check the deviation from the permissible values. When loading with a tape measure, the longitudinal dimensions of the pipes (i.e., length) are measured and then, having calculated the theoretical weight of 1 running meter. multiply it by the total length of the pipes.

In relation to such dimensions of steel pipes, as well as to the dimensions of pipes made of any other material, the requirements of GOSTs are quite loyal. For example: "pipes with a diameter of over 152 mm are made with a length of at least 5 m." Therefore, despite the fact that used pipes are cut a little before sale, it is impossible to distinguish them in length from new ones. It is worth remembering that many when selling straight or spiral pipes do not indicate the length. This means that the length of the pipes corresponds to GOST (usually about 11 meters). If the price list (announcement) indicates that pipes are sold cut at the seams, then their lengths are also within the limits allowed by GOSTs. Seamless pipes are allowed to be made of unmeasured length - from 4 meters to 12.5 meters. Therefore, when purchasing pipes, be interested in GOSTs.

Steel pipe diameters

The diameter of a steel pipe is determined by the outer diameter for electric-welded and seamless pipes, and for vgp - by the nominal diameter (often referred to as DN). That is, inner pipe diameter- Du, outer diameter of pipes Dн, thread diameter - G... Pipes are sized in millimeters, but WGP pipes are often denoted in inches (").

VGP pipe size (GOST 3262-75)

Main pipe dimensions: 15mm (1/2 ""); 20mm (3/4 "); 25 mm (1 "); 32 mm (1 1/4" inch and a quarter); 40 mm (1 1/2 "); 50 mm (2"). There are also the following DN: 10 mm, 65 mm, 80 mm, 90 mm, 100 mm and even 125 mm - but they are rarely used and, as a rule, are replaced by other types of steel pipes (for example, electrowelded). Most often, pipes 3/4 "are used for risers, for internal wiring 1/2".

Electric pipes (GOST 10704-91)

E / s longitudinal welded pipes are of the following outer diameters (in millimeters): 10; 12; thirteen; 14; sixteen; 17; 17.5; eighteen; nineteen; twenty; 21.3; 22; 24; 25; 26; 28; thirty; 32; 33; 33.7; 36; 38; 40; 42; 43; 45; 48; 51. With a diameter of up to 57 mm, a VGP pipe of the appropriate size is used. The most popular are longitudinal welded pipes in accordance with GOST 10704-91 in sizes from 57 mm and above. Their main diameters: 57; 60; 63.5; 76; 89; 102; 108; 114; 127; 133; 140; 146; 159; 168; 178; 193; 219; 245; 273; 325; 377; 426; 530.

Welded pipes for gas and oil pipelines (GOST 20295-85)

They start with a diameter of 159 mm and up to 530 mm come with the same dimensions as pipes in accordance with GOST 10704-91. Major larger diameters (in millimeters): 630, 720, 820, 1020, 1220, 1420.

Seamless hot-smoked pipes size (GOST 8732-78)

Commonly used hot rolled seamless pipe diameters (mm): 32; 38; 42; 45; 51; 54; 57; 60; 63,5; 68; 70; 73; 76; 83; 89; 95; 102; 108; 114; 121; 127; 133; 140; 146; 152; 159; 168; 180; 194; 203; 219; 245; 273; 325; 351; 426.

Manufacturing plants can produce any size of pipes at the request of the customer.

Internal pipe diameters

According to the standard series adopted in most countries, pipes have the following inner diameters, measured in mm: 6, 10, 15, 20, 25, 32, 40, 50, 65, 80, 100, 125, 200, etc.

The system of measurement by thread diameter in inches is also used. 1 "= 25.4 mm.

The table shows pipe dimensions(diameters) in mm and inches:

Nominal pipe diameter (Dy) mm	Thread diameter (G), inch	Outside pipe diameter (Dн), mm
		Steel water and gas pipe	Seamless	Polymer

When installing a steel pipe system for residential buildings, pipes with an inner diameter of Dy = 15, 20 and 32 mm are usually used.

Cast iron free-flow pipes with a diameter of Dу = 50 and 100 mm are the most commonly used.

Currently, pipes made of polymeric materials are increasingly used for laying indoor pipelines, which are replacing cast iron and steel.

It should be noted that, depending on the type of material used in the manufacture of pipes, different designation systems are used. In most cases, steel and cast iron pipes are designated by nominal bore or internal diameter. Copper pipes, some types of steel pipes, pipes made of polymeric materials are designated by the outer diameter. Therefore, you should carefully consider the choice of the required pipe, as well as take into account the wall thickness.

Outside pipe diameters and pipe wall thickness

Outside diameter, Dн mm	Wall thickness, mm
Steel pipes for water and gas supply GOST 3262-75
Electric-welded steel pipes GOST 10704-91 GOST 10705-80
Plastic pipes

Description of pipe diameters contains data on all parameters - internal, external, conventional, nominal. Knowledge of the characteristics is required when installing the network and selecting fittings. Otherwise, improperly assembled communication threatens with loss of tightness, a short service life due to breakdowns. Next, consider the pipe diameters in inches and millimeters.

Dimensions of pipes

They are reflected in the corresponding GOSTs and TUs and contain the following definitions:

• The outer diameter is the main characteristic of the pipe.
• Inner diameter.
• Nominal.
• Conditional pass.

More about the differences:

• Outside diameter it is classified into small, medium and large values ​​- which is why the pipe is used in appropriate conditions. Small diameter is used - in apartment and private water supply systems, medium - in urban communications, large - in industrial. The outer diameter is the most important characteristic of the pipe, as it determines the required thread of the fitting. Designation - Dн.
• Inner diameter or true... Depends on the thickness of the wall and can be strikingly different from the external, even with the same dimensions of the latter. It is designated as Dvn. Calculated mathematically (Dn - 2S), where S is the pipe wall thickness. An example is the outer diameter of a pipe - 60 mm. Minus the walls of 4 mm, its inner diameter is 52 mm. With increasing wall thickness, the internal parameter decreases.
• The conditional passage or diameter of the pipe lumen is marked as Dу... This is the average inside diameter, rounded up to the standard value. For example - the outer diameter of the pipe will be 159 mm. The true inner diameter after deducting the wall thickness of 5 mm is 149. Then the nominal diameter after rounding is 150 mm. This parameter is considered for the selection of suitable fittings and fittings.
• Nominal diameter... The concept was introduced in order to standardize the marking of pipes from different materials. The value is equal to the nominal size and is marked in inches. This allows you to correctly select pipes from various raw materials for combining in a network - steel and plastic are marked in inches, copper and aluminum - in millimeters.

Thus, the correct selection of components for home communications in accordance with the described concepts is not difficult. Conversion tables of sizes from inches to millimeters and vice versa will help in self-repair and replacement of defective network sections.

The geometric dimensions of the pipes are determined by the following characteristics:

• - external diameter;
• - wall thickness;
• - the ratio of the outer and inner diameters;
• - length.

Pipe assortment(available sizes, technical conditions for the production and use of steel pipes) are standardized by state standards GOST). GOSTs are developed taking into account the technology for the manufacture of pipes and steels used in the production.

In the CIS market, it is customary to indicate pipe dimensions in mm (millimeters), but you can also find pipe dimensions in inches. The latter are most often indicated for imported pipes. The length of rolled pipes is measured in meters.

Steel pipe diameter

The diameter of a steel pipe is determined by:

• - outer diameter for electrically welded and seamless pipes;
• - nominal bore diameter for VGP pipes.

• — Nominal diameter(Du or Du) - inner pipe diameter.
• — Conditional pass- a conventional value, which is the value of the actual internal diatreme, rounded to the nearest of the standard series, and serves as a reference point for the selection of the dimensions of the remaining parts and equipment. Its value is standardized according to GOST 28338-89. Measured in inches or mm.
• — Inner diameter- the actual value of the parameter obtained by direct measurement, as a rule, is indicated in mm;
• — Outside diameter of pipes(Дн or Дн) - the actual pipe diameter, taking into account the wall thickness, is indicated in mm;
• — Thread diameter(G).
