Steel Pipe Specifications Under British Standard

I. Overview of steel pipe specifications under British Standard

The British Standard specifies steel pipe specifications in two categories: metric and imperial. The steel pipe specifications are formulated differently depending on whether the metric or imperial system is used. In the metric system, the diameter is measured in millimeters and the wall thickness is measured in millimeters or inches. In the imperial system, the diameter is measured in inches and the wall thickness is measured in SWG or BWG. Furthermore, there are specific steel pipe specifications, including seamless steel pipes for structural and boiler use, that vary depending on the application and manufacturing process.

II. Common steel pipe specifications under British Standard

1. BS EN 10255 steel pipe

BS EN 10255 steel pipe is a welded steel pipe for low-pressure fluid transportation. It is formulated according to metric specifications, with diameters from 15mm to 165mm and wall thicknesses from 1.8mm to 6.35mm.

2. BS1387 steel pipe

BS1387 steel pipe is a commonly used plain welded steel pipe for gas, water supply and drainage. It is formulated according to metric specifications with diameters from 15mm to 150mm and wall thicknesses from 1.6mm to 5.4mm.

3. BS EN 10219 steel pipes

BS EN 10219 steel pipe is a welded structural steel pipe for use in the construction and mechanical fields. It is formulated according to metric specifications with diameters from 21.3mm to 219.1mm and wall thicknesses from 1.5mm to 8.0mm.

4. BS EN 10210 Steel Pipe

BS EN 10210 steel pipe is a seamless structural steel pipe for use in the construction and mechanical fields. It is formulated according to metric specifications with diameters from 21.3mm to 219.1mm and wall thicknesses from 2.3mm to 60mm.

III. Summary

The British Standard includes steel pipe specifications that are made according to metric and imperial specifications. The metric specifications are versatile and can be used for low-pressure fluid transportation, construction, machinery, and other fields. The imperial specifications are mainly used in the industry and chemical industry. Understanding the specifications for steel pipes under the British Standard can aid in making informed purchasing and selection decisions.
