Technical Requirements For Stainless Steel Valves

Ningbo Fenfa Valve Co.,Ltd | Updated: Oct 14, 2016

Stainless steel valves are mainly stainless steel led the production of valves, corrosion protection, for the purpose of cleaning. Stainless steel valves are widely used in anti-corrosion pipe plant stock project, has very good corrosion resistance characteristics. Stainless steel valves generally use the most of our products have stainless steel globe valve, stainless steel valve, stainless steel ball valve, stainless steel valve, stainless steel needle valves, stainless steel butterfly valves and other products, wide range of applications. Structure and stainless steel valves with soft seals seal structure, such as stainless steel ball valve soft seal structure is the most common, inexpensive, widely used, good sealing performance. Hard sealed structure of most is the stainless steel gate valve, stainless steel valve, stainless steel valve. Stainless steel valves manufacturing technology of casting and forging class, casting class bias of large diameter valves, forging class general applications with small-caliber valve manufacturing. Finished product casting class cheap, forging such costs are relatively high, of course, its performance is better than casting a lot, such as high pressure and high temperature resistance excellent much, so often used in fine pipe high pressure working conditions to the stainless steel valves, low-voltage or large-diameter pipeline valves generally use stainless steel valves, the majority of the class. Stainless steel valve material must undergo a rigorous inspection of storage, if the material is not qualified directly affects the product's corrosion resistance, pressure resistance and service life of the valve. Stainless steel materials must be performed in strict accordance with the national standard, material elements must be in accordance with the regulations. In the valve industry and other industries in the market, do not meet the corrosion resistance of stainless steel will have a rust spot or not, as we often use Cup saw spots of rust on the surface, this is the reason why material standards. Is the same standard stainless steel valves stainless steel valve after use, there will be spots of rust on the surface, or use easy to corrode away, short life problems. Stainless steel valve processing should also be aware of some issues, such as the stainless steel body of machine tool equipment and accessories must be better, good head to manufacture precision valves. Stainless steel valves, and under conditions of medium, pressure, temperature and other conditions of your choice of stainless steel valves, if the media, nitric acid generally choose stainless steel CF8 (304), as acetic acid not choose stainless steel CF8M (316) or CF3M (316L) and other materials.
