Stainless Steel Flange

Flange (also known as flange or flange) is a part of the pipe and pipe connected to each other. It is connected to the pipe end. There are holes in the flange, and bolts can be worn to make the two flanges tightly connected. Flanged pipe fittings are pipes with flanges (flanges or lands) that can be cast or threaded or welded. Flange (joint) is a pair of methods. Lan, a gasket and a plurality of bolts and nuts. The gasket is placed between the two flange sealing surfaces. After tightening the nut, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the sealing surface with irregularities. At the same time, the joints are tight and tight. Some fittings and equipment have their own flanges, which are also flange connections. Flange connections are an important connection method for pipeline construction.
Main role
1. Connect the pipeline and maintain the pipeline sealing performance;
2. Facilitate the replacement of a certain pipeline;
3, easy to open and check the pipeline;
4. It is convenient to close a certain pipeline.
Precautions for use
1. In order to prevent the corrosion between the eyes 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 layer is fast cold, and the narrow weld bead is suitable.
2, the electrode should be kept dry when used, titanium calcium type should be dried at 150 ° C for 1 hour, low a hydrogen type should be dried at 200-250 ° C for 1 hour (can not be repeated repeatedly, otherwise the skin is easy to crack and peel off), to prevent The electrode coating is sticky with oil and other dirt to prevent the weld from increasing the carbon content and affecting the quality of the weldment.
3. When welding stainless steel flanged pipe fittings, it is repeatedly heated to precipitate carbides, which reduces corrosion resistance and mechanical properties.
SINHOO is one of the earliest suppliers and manufacturers of Stainless Steel Flange in China. Equipped with its own factory, can provide the wholesale quantity you want.
