The customer’s factory repaired two pipe groups and entrusted our company to “copy” them. The pipe diameter is DN250-DN200, the wall thickness is STD, the material is ASTM A234 WPB, and the flanges at both ends are FF surface CLASS150 pressure level neck welding flanges, made of ASTM A105.
After production, our factory conducts X-ray inspection, size inspection, sprays epoxy anti-corrosion coating and then ships. The customer has installed it and is using it normally.
