Pipe Groups

ISO 4200 divides welded steel pipes and seamless steel pipes into two groups.

Group 1: General-purpose steel tubes.

Commonly used standards: API 5L, ASTM A53, GB 3091, and so on.

Group 2: Precision steel tubes.

Commonly used standards: ASTM A519, DIN 2391, and EN 10305-1.

This paper mainly discusses the weight table of steel tubes for general purposes, if you want to know the weight table of steel tubes for precision steel tubes, please click on the following standard PD file to view Page 10 Table 3.

ISO 4200：1991 .pdf

General-purpose steel tubes and precision steel tubes are mainly divided according to the differences in manufacturing precision, material, and performance.

General-purpose steel tubes usually refer to steel tubes with relatively low production processes and technical requirements, which are mainly used for general low-pressure fluid transportation, structural components, and so on.

Precision steel tubes, on the other hand, refer to steel tubes with higher precision dimensions, better surface quality, and stricter material and performance requirements, and are commonly used for high-precision and high-performance components in automotive, machining, petrochemical, and other fields.

In terms of outside diameter and wall thickness, precision steel tubes often have stricter tolerance requirements to meet the needs of specific applications.

Pipe Weight Chart of Group 1

ISO 4200 standard for general purposes divides the outside diameter of steel tubes into three series

Series 1

Series 1: Series for which all the accessories needed for the construction of piping systems are standardized.

Series 2

Series 2: Series for which not all accessories are standardized.

Series 3

Series 3: Series for special applications for which very few standardized accessories exist.

Calculation Method

M=(D-T)×T×0.0246615

M is the mass per unit length in kilograms per meter;

D is the specified outer diameter in millimeters;

T is the specified thickness in millimeters;

The coefficient 0,0246615 takes into account the density equal to 7.85 kg/dm³

The results of the calculations are rounded to the three significant figures for values below 100 and to the nearest whole number for larger values.

Table 2- Dimensions and masses per unit length, group 1 and Table 3-Dimensions and masses per unit length, group 2 in the ISO 4200 standard are also calculated on this basis.

Preferred Thickness

To simplify the selection of standardized sizes for pipes and accessories.

ISO 4200 also provides seven ranges of preferred thicknesses for the outside diameter of steel pipes for general purposes: A, B, C, D, E, F, and G.

Pipe Weight Chart - ISO 4200 Preferred thickness

A, B, C, E, F, and G: Typically used for stainless steel tubular products;

A, B, and C: Usually only used for stainless steel, but in some cases can be used for other types of steel;

D and E: Preferred thicknesses listed are specifically for general-purpose flat-end commercial quality steel tubing;

D: Not applicable to butt-weld attachments.

Equivalent Standards

ISO 4200 Table 2 and EN 10220 Table 1 are the same in the division of steel pipe series and in the statistics of the dimensional weight of steel pipe with wall thickness ≤ 65mm.
But ISO 4200 does not have the wall thickness of 70mm ≤ T ≤ 100mm of steel pipe dimensional weight statistics.

EN 10220 stipulates the dimensional weight of seamless and welded steel pipe. And then there is no division of steel tubes into two groups: general purpose steel tubes and precision steel tubes.

Therefore, although the two standards are often regarded as equivalent or at least highly compatible in practice, there may be differences in the scope of application and specific details, especially in the case of specific applications or regional requirements.

Purpose of the Weight Table

pipe weight chart is to provide guidance for regulating the selection of dimensions for all activities related to the standardization of steel pipes, so that calculations can be readily made to avoid the use of different qualities for the same size of pipe in different countries.
