Among the important pressure parts of ultra (supercritical) boiler, superheater and reheater are the parts with high working temperature and bad working environment. Previously, all such materials used in China were imported from abroad, while only steel material manufacturers in the world have limited capacity. Such materials have a large gap, expensive import prices, difficult procurement and short supply, which seriously affected the production of ultra supercritical boilers and the development of electric energy in China. At present, China's demand for utility boiler tubes is about tons and with the continuous improvement of ultra (supercritical) power generation technology, the demand is expanding. Several large domestic enterprises have invested a lot of human and financial resources in the R & D and production of such products, and have made considerable achievements. On the one hand, it has made its own contribution to the development of national electric power industry, but also brought considerable economic benefits to enterprises.Tecpan-Guatemala,Decorative stainless steel pipe: usually the outer wall is relatively bright, so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe, the surface of stainless steel product pipe is also a bright surface, and a small number of pipes with acid pickling industrial surface. As mentioned above, stainless steel product pipe belongs to the purpose of stainless steel products, because the outer diameter size, mechanical properties, acid, alkali and corrosion resistance of stainless steel pipe are relatively good, Therefore, stainless steel pipes are generally used as anti-corrosion materials or hardware products in large-scale production enterprises. The production process of stainless steel pipes is one-time forming, and nitrogen protection is also added during welding.It has the characteristics of high efficiency and low cost.
