Spcification

Electric Fusion Welding Pipe(EFW steel pipe) refers to an electron beam welding, the use of high-speed movement of the electron beam directed impact kinetic energy is converted to heat the work piece so that the work piece leaving the melt, the formation of the weld. lt is mainly used for welding dissimilar steel welding sheet or which high power density, metal weldment can rapidly heated to high temperatures, which can melt any refractory metals and alloys. Deep penetration welding fast, heat-affected zone is extremely small so small performance impact on the joints, the joint almost no distortion. But EFW welding steel pipe has a requirement on a special welding room because welding using X-rays.

JOCE Pipe

The continuous shaft twisting J-C-O (J-ing, C-ing and O-ing) process is adopted, which has the characteristics of high forming accuracy, high efficiency and uniform forming stress distribution. The outer diameter of the production specification is Φ356~Φ1626mm, the wall thickness is 6~50mm,It is mainly used for transportation pipes for various purposes such as petroleum, chemical industry, natural gas, electricity, city gas, water supply and drainage, and is also widely used in construction, bridges, docks and other engineering fields.
