From this page, you can learn what is the product of our production and sales of duplex stainless steel pipes, industrial welded pipes, stainless steel flanges, etc.

Stainless steel flanges will not cause corrosion, pitting, rusting, and are not easy to wear. Stainless steel is one of the strongest materials in construction metal materials. Because of good corrosion resistance, it can make structural components permanently maintain the integrity of the architectural design. There are more and more types of stainless steel flanges…

The stainless steel flange should be a component that many people know. In fact, the flange is an accessory used to connect the stainless steel pipes or stainless steel tubings. It is used to connect two places with each other, and its usage is very simple. Even for such a small part, we should learn…

Experiments and results of duplex stainless steel pipe welding Man has produced and used duplex stainless steel for almost 80 years. Early alloys, such as malleable alloy 329 and cast alloy CD4MCu, contained far more ferrite than austenite. People do not pay attention to the importance of nitrogen. Many alloys contain very little nitrogen, so…

At low temperature, the stainless steel tubing will have a great change in resistance, linear expansion coefficient, thermal conductivity, mass melting and magnetic properties. Major changes Resistance, linear expansion coefficient becomes small at low temperature;Thermal conductivity and mass heat capacity decrease sharply at low temperatures;Young's modulus (longitudinal elastic modulus) increases as the temperature decreases;The formation…
