ASTM Forged RF Ss316 Slip on Stainless Steel Flange

  ASTM Forged RF Ss316 Slip on Stainless Steel Flange is divided into the following six basic types: flat welding 

 flange, welding flange, socket welding flange, loose flange, threaded flange and 

 integral flange.

　　Flat welding flange: It is used in the case of more dielectric conditions, If low pressure does not purify compressed air, low pressure circulating water, its advantage is the price is cheaper;Welding flange: one of the most commonly used, it is welded to the pipe, the welding joints quality is better, and the neck of the flange is used in the taper transition, which can be subjected to harsher conditions;Socket welding flange: used in the pipeline for PN less than 100 MPa, DN less than 40;Loose flange: it is often used for low medium temperature and pressure.When corrosive medium is strong. part of the flange contact medium (flanging nipple) as the corrosion resistance of high grade materials such as stainless steel materials, while the external use of low grade materials such as carbon steel material of flange ring clamp it in order to realize the seal;Integral flange: often is the flange with equipment, tube, pipe, valve etc., this type is used in equipment and valve.
