Hot dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly bonded alloy coating that provides superior corrosion protection to the steel.
Jan 23, 2019 · Galvanized steel pipes are divided into hot dip galvanizing and electric steel zinc. The hot dip galvanizing galvanized layer is thick and the cost of electro galvanizing is low. Blowing oxygen welded pipe. used as a steel pipe for oxygen blowing, generally with small diameter welded steel pipe, the specifications are from 8/8 inch to 2 inch.

Cold rolled electric welded (CREW) tube is produced per ASTM A513 Type 2. CREW is produced from hot rolled strip steel that has been cold reduced. Due to the extra cold working at the steel mills, A513 Type 2 tubing will have tighter wall thickness tolerances, improved surface condition and a narrower range of mechanical properties than A513 Type 1.
Welded pipe NPS 4 and under may be butt welded. Welded pipe over NPS 4 shall be electric welded. Pipe shall be coated with zinc inside and outside by hot dip process. The steel pipe shall meet the tensile requirements for tensile strength and yield strength specified for regular, intermediate strength, and high strength grades.
