Detailed Information:

This British Standard specifies the requirements for electric resistance welded steel tubes (ERW) used in mechanical and general engineering applications. BS 6323 Part V specifies the requirements for electrical resistance welded steel tubes. As the name suggests, this standard applies to tubes made of hot-rolled or cold-reduced steel, with circular, square, rectangular, or elliptical cross-sections.

In order to manufacture ERW pipes, steel strips are formed into tubes and then the edges are welded with electric resistance welding. In this way, a strong joint is created without the need for additional welding materials, and ERW pipes are commonly used in structural and mechanical construction applications like building frames, bridges, and pipelines.

A specific chemical composition, mechanical properties, dimensions, tolerances, and testing requirements are specified for BS 6323 Part V ERW pipes. It is also important for these pipes to comply with the requirements of other British Standards for steel tubes, including BS EN 10255 and BS EN 10219.

It is generally recognized that BS 6323 Part V ERW pipes are designed to provide reliable and durable performance in a variety of engineering applications and are subjected to rigorous testing and quality control to ensure their suitability for use.

BS 6323 Part V ERW Pipes Delivery Executions and Protection

Tube Ends	Protection
We Supply all tubes with clean, square-cut ends. Deburring and chamfering, we carry out on request on request.	• Black and Bare • External Varnished with Black or Clear Lacquer
Tube surface	Mill test certificate.
We supply Tubes without anti-corrosive treatment, but anti-corrosive treatment is available, and we carry it out on request.	• MTC is issued by EN 10204.

Packaging	Marking	Labelling
We bundle Tubes as standard with steel straps into hexagonal bundles with one end flush. Length sorting can be carried out on request. Tubes can also be bundled in multiples. Bundle weights are adjusted as requested by the customer. Each bundle contains tubes from a single cast/heat only.	Each tube is marked with tube type, heat number, steel grade, and size. Information is repeated along the length of the tube. Bundles are also labelled with a tag with alphanumeric and barcode info. Other markings, such as stamping, can be made on request.	Material delivered directly from our mill is marked by automotive standards, i.e., with both alphanumeric and barcode information. Specific data can be added according to the customer on request.
