This specification covers single wall construction tubing wherein the joint is electric resistance welded. There are requirements for base metal, the optional coating materials and the coated tubing. These requirements are applicable to the product coming out of the tube mills and the coating application lines, which are sometimes separate facilities. This tubing is used in the production of customized parts and assemblies. It is recommended that those parts and assemblies be validated for corrosion performance, conductivity and continuity, strength, appearance and other critical properties unique to the particular application.
