Large diameter welded steel pipe production processLarge diameter welded steel pipe production process mainly adopts cold forming process (JCOE), which is a gradual forming method of steel plate, so that the steel plate is formed into the required bending degree under the standard die of the upper p
With the rapid development of my country's iron and steel industry, the welded pipe industry using steel strip products as raw materials has also developed rapidly. The substantial increase in the output of welded pipes in my country is based on the rapid increase in the number of welded pipe units.
904L is a highly alloyed austenitic stainless steel with very low carbon content. The steel is designed for harsh corrosive environments. The alloy was originally developed for corrosion resistance in dilute sulfuric acid. This feature has been proved to be very successful after years of practi
