Comparison of advantages of stainless steel welded pipe and stainless...
Posted On 03/21/2018 15:36:11 by flange

Now the production technology of stainless steel welded pipe is relatively perfect. It has replaced seamless steel pipes in many aspects, such as petroleum, automobile, paper making, air conditioning and so on, and its price is less than 1/5 of seamless pipe. The market demand of stainless steel seamless Pipe is mainly manifested in basic indu... Read More

Processing technology of super duplex stainless steel welded pipe
Posted On 03/19/2018 16:24:47 by flange

Because the offshore oil platform riser has long suffered the wave scour, it is necessary to have high strength and excellent resistance to point corrosion material. In all kinds of alternative materials, because super duplex stainless steel possesses austenite and ferrite structure at the same time, it has many advantages such as high corrosion resista...

Cause of cracking of 310S stainless steel pipe
Posted On 03/18/2018 22:46:15 by flange

The content of chromium and nickel in 310S stainless steel is higher, and its corrosion resistance is better than that of ordinary 18-8 stainless steel. In boiling nitric acid with a concentration above 68.4%, the corrosion resistance of ordinary 18-8 stainless steel is not satisfactory, but 310S stainless steel can be applied in 65 ~ 85% nitric acid. 3...
