Advantges of electric welding
Resistance welding method developed rapidly since its inception in the late 19th century, especially with the rise of mass production of the automotive industry and other enterprises, the increasingly widespread application. According to statistics, the current resistance welding method accounted...Read more -
Advantages of spiral weld steel pipe
Spiral welded pipe production uses hot rolled coil. The alloy content of the coil is often lower than similar grades of steel plate, improving the weldability of the spiral welded pipe. Due to the rolling direction of spiral welded pipe coil is not perpendicular to the pipe axis direction, the cr...Read more -
Advantages of electro-galvanized
Electro-galvanized is an electrolytic process to obtain coating the surface of the steel pipe. Which is to strengthen and improve the performance of the steel surface, made steel pipe decorative appearance, corrosion resistance, anti-wear and special optical, electrical, magnetic, thermal perfo...Read more -
A333-6 low temperature steel pipe welding
A333-6 steel pipe is a low-temperature steel. The minimum temperature of 70 ° C. Usually normalized or normalized and tempered state supplier. A333-6 steel carbon content is lower, so hardened the tendency and cold cracking tendency are relatively small. Material toughness and ductility is better...Read more -
316l stainless steel surface hardening process and heat treatment process
Stainless steel tube heat treatment main purpose is to change the inner pipe metal matrix structure, improve the hardness of stainless steel pipe, but because it is not fundamentally change the pipe morphology, and therefore can not effectively improve the strength and toughness of the stainless ...Read more -
