Product Description
What is EN 10255/ BS 1387 Welded Steel Pipe?
EN 10255 Welded Steel Pipe refers to steel pipes produced by a welding process that conform to the European standard EN 10255. This standard specifically covers non-alloy steel tubes suitable for welding and threading, primarily intended for the conveyance of fluids like water, gas, and air, as well as steam, generally at lower pressures. It’s the successor to the older British standard, BS 1387.
