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 -
Chinese Steel promising
First of all, supply and demand will keep in balance in the next year, but the species differentiation, exports declined. In fact, cold, hot plate growth rate of more than 5%, but building materials, seamless tube have negative growth, the differentiation of the species has been very clear. Curre...Read more
