Stainless steel blind plate
The stainless steel blind plate is suitable for improving the corrosion resistance and welding property, and the appropriate amount of stable element Ti, Nb, Mo, etc., is better than the chromium stainless steel flange.
Stainless steel blind use of the same type chromium stainless steel flange welding electrode (G302, G307), should be above 200 ℃ preheat and around 800 ℃ tempering treatment after welding。 If the welding piece cannot be heat treated, stainless steel flanged tube welding rod (A107, A207) should be used。
Stainless steel blind plate has good corrosion resistance and oxidation resistance, widely used in chemical, fertilizer, petroleum, medical machinery manufacturing。
Flanges are also called flanges or flanges. The flange is the part that connects the pipe to the pipe, which is connected to the pipe end. The flanges have holes in it and the bolts fasten the two flanges. The flange is sealed with gasket. Flange tapping flange and welding flange.
Flange is a type of disc part, which is common in pipeline engineering. Flange is used in pairs and with matching flanges on valve. In pipeline engineering, flange is mainly used for piping connections. In the pipe that needs to connect, various installation flange, low pressure pipe can use silk to connect the flange, 4kg above pressure to use welding flanges. Add a gasket between two flanges, then bolt to tighten. Different pressure flanges have different thickness and use different bolts.
Main functions of stainless steel blind plate:
1。 Connect the pipeline and maintain the sealing performance of the pipeline;
2. Facilitate the replacement of a certain pipeline;
3. Easy to disassemble the inspection pipeline;
4。 Facilitate the closure of a certain section of the pipeline。
