Application Of Stainless Steel Flanges in Various Industries

Application of stainless steel flanges in various industries
Stainless steel flange plate must be used together with a high-pressure gasket, not only can increase the sealing degree, but also greatly improve the performance of the flange plate
Stainless steel flange shall have sufficient strength and shall not be deformed when tightening. The flange sealing surface shall be flat and clean, and the oil and rust shall be carefully cleaned when installation.
Stainless steel flange material :304,304L, 321,316,316L, 310S, and other materials,Stainless steel flange pressure rating: 0.6Mpa~32Mpa,150Lb~2500Lb,PN0.25-PN42.0.Stainless steel flange range of sizes：1/2”-80”,DN15-DN2000.
Stainless steel flange is a disc part, the most common in pipe engineering, stainless steel flange is used in pairs, in pipe engineering, a flange, low pressure pipe can be wire connected stainless steel flange, 4 kg pressure using welding flange, two flange plus gasket, then fastened with bolts, different pressure flange has different thickness and different bolts, stainless steel flange use precautions:.1. In order to prevent corrosion due to the heating of the flange cover, the welding current should not be too large, about 20% less than the carbon steel electrode, the arc should not be too long, the layers are fast cold, and the narrow welding path is appropriate.2. The rod should be kept dry when used, titanium calcium type should be dried by 150℃ for 1 hour, low a hydrogen type should be dried by 200-250℃ for 1 hour (can not be dried repeatedly for many times, otherwise the drug skin is easy to crack and peel), to prevent the welding rod skin sticky oil and other dirt, so as not to increase the carbon content of the weld and affect the quality of welding parts.3. When the stainless steel flange fittings are welded, repeated heating will precipitate the carbide to reduce the corrosion resistance and mechanical properties.
