Description

BS 6323-5 ERW1 KM Boiler Tube

BS 6323-5 ERW1 KM Boiler Tube is a British Standard specification for electric resistance welded (ERW) carbon steel tubes used in boiler applications. The ERW1 grade indicates that the tube is manufactured using a low carbon steel material, while the KM designation signifies that the tube is suitable for high temperature and pressure boiler systems. This specification sets out the requirements for the dimensions, mechanical properties, and testing of the boiler tube to ensure its e and reliable performance in industrial boiler applications.
