STAINLESS STEEL FLANGES

Specifications

DIMENSIONS

Wall Thickness: Sch5S-Sch160S

Outer Diameter: DN6-DN750: ¼’’-30’’

CLASSIFICATIONS

SW (Socket Welding) flange, WN (Welding Neck) flange, SO (Slip-On) flange, BL (Blind) flange, LJ (Lap Joint) flange, TH (THreaded) flange, ORI (Orifice) flange

PRESSURE LEVEL

150lbs-2500lbs

FEATURES

• TH Flange is jointed to pipes through its thread, hence the pressure imposed upon the pipe is relatively small. It is widely used in construction projects, easy for installation, free from welding requirements. It has male face and flat face.
• SW Flange is usually used for pipeline which requires PN ≤ 10.0Mpa, DN ≤ 80;
• WN Flange is also named high-necked flange, applicable to situations where has high pressure, high temperature and large diameter pipe.
• SO Flange is known for a low neck in terms of its shape. The performance of rigidity and carrying capacity of SO Flange are enhanced. In comparison with WN Flange, it calls for extensive labor on welding and high consumption on welding rod. It is vulnerable to volatile temperature, high pressure, heat and repeated bending. Since it is easy to install and eliminates the risk of damaging welding lines, it still enjoys high popularity.
