Stainless steel flange generally has a strong sealing, tensile, bending resistance, compressive resistance, etc., according to a variety of properties, stainless steel flange can also be divided into socket weld flange, loose flange, butt weld steel flange, overall flange, flat welding steel flange, etc., each stainless steel flange are their own product parameters, here Siyuan pipe fittings company to share with you in detail.

　　① socket weld stainless steel flange: commonly used in PN ≤ 10.0Mpa, DN ≤ 40 pipeline.

　　② butt welding steel stainless steel flange: for flange and pipe butt welding, its structure is reasonable, strength and steel degree, withstand high temperature and high pressure and repeated bending and temperature fluctuations, reliable sealing. Nominal pressure of 0.25-2.5Mpa butt welding flange using concave and convex sealing surface.

　　③ loose stainless steel flange: loose flange commonly known as live flange, welded ring live flange, flanged live flange and butt welding live flange. Commonly used in the medium temperature and pressure are not high and the medium is more corrosive situation. When the medium is more corrosive, the part of the flange contact medium (flange short section) for corrosion-resistant high-grade materials such as stainless steel and other materials, while the external use of low materials such as carbon steel material flange ring clamping it to achieve sealing.

　　④ overall stainless steel flange: often flange and equipment, pipes, valves, etc. into one, this type is commonly used in equipment and valves.

　　⑤ flat welding stainless steel flange: applicable to the nominal pressure of not more than 2.Mpa carbon steel pipeline connection. Stainless steel flange sealing surface can be made smooth, convex and tongue and groove type three. Smooth stainless steel flange application volume is larger, more for the media conditions more moderate, such as low pressure non-purified compressed air, low pressure circulating water, it has the advantage of relatively cheap.
