Stainless steel seamless tube of metal and oxygen in the atmosphere to react, in the appearance will form an oxide film. However, the oxidation of the iron oxide formed on the ordinary carbon steel pipe continuously causes the corrosion to be enlarged, and as a result, the pores are formed. This good stainless steel seamless tube is damaged, we can use paint or oxidation-resistant metal such as zinc, nickel and chromium plating to cover the...

the material for Duplex and Super Duplex
Duplex and Super Duplex2022-01-05 Posted by WilsonDuplex Duplex is a material that has approximately equal amounts of austenite and ferrite. These combine excellent corrosion resistance with high strength. Mechanical properties are approximately double those of singular austenitic steel and resistance to stress corrosion cracking is superior to type 316...
What Are the Different Types of Metal Flanges?
What Are the Different Types of Metal Flanges?2022-01-05Posted by WilsonCommonly found in plumbing applications, metal flanges provide a quick and easy method for joining lengths of pipe to one another. A flange consists of an external ring around one end of a structure, pipe, or tube that contains matching boltholes for easy assembly. In contrast, pipes that require joining but lack any flanges normally involve either welding...
