The common materials of the right angle valve body
- Nov 22, 2017 -


The materials of the valve body of the right angle valve, according to different process and medium are different. Among them, the more commonly used are cast iron, cast steel, carbon steel, copper, stainless steel, and so on.

Grey cast iron:The advantage is low price and wide application, and it can adapt to water, steam, oil,gas and other media. Therefore, it can be used in petrochemical, printing,dyeing and textile industries. The applicable temperature is from - 15 ℃ to 200 ℃, the nominal pressure is not greater than 1.6 MPa.

Nodular cast iron:It is a kind of cast iron。 It is better than ordinary gray cast iron in performance. The applicable temperature is from - 30 ℃ to 350 ℃, the nominal pressure is not more than 4 MPa. In addition, the applicable medium is water, sea water, steam, air, gas and oil product, etc.

Carbon steel:Its advantage is that it has a good resistance strength to the thermal expansion, impact load and pipeline deformation, so its use is very wide. Its applicable working temperature is from - 29 ℃ to 425 ℃. The applicable medium is water, natural gas, compressed air, liquefied gas, high temperature and low temperature oil product, and superheated steam.
