These are available in raised face or flat face configurations. These are used in piping industry, mechanical, chemical and many other sectors.

When the carbon content of the a333 gr 6 welded pipe chemistry is lower, the chance of cracking in the welded area is also lower. However, some manufacturers prefer seamless pipes over welded pipes. The reason behind this is that the performance of the a333 gr 6 seamless tube is almost 20% higher than the welded one in high pressure environments.
