Welding process: raw materials - Flat - end uncoiling shearing and welding - Welding - - loop forming - both inside and outside the weld bead removal -- pre correction - induction heat treatment - sizing and alignment: eddy current testing - cut - - Pickling - water pressure check final inspection (strictly) - Packaging - shipment.
Welded pipe is widely used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, is one of China's twenty major product development.
We have adopted advanced production equipment and technologies to manufacture our pipe tee and pipe elbow, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
