DN40 DN80 DN100 DN150 Plate Steel Stainless Steel Flanges
1. Stainless steel flanges is a part of pipe connected with each other. Connected to the pipe end. There are holes on the stainless steel flanges, through which bolts can be threaded to make the two flanges tightly connected. The stainless steel flanges is sealed with gasket.
2. Stainless steel flanges pipe fittings refer to the pipe fittings with stainless steel flanges. It can be cast, threaded or welded. The flange connection is composed of a pair of flanges, a gasket and several bolts and nuts.
3. The gasket is placed between the two stainless steel flanges sealing surfaces.
4. After the nut is tightened, the specific pressure on the gasket surface reaches a certain value, and the deformation occurs, and the uneven parts on the sealing surface are filled, so that the connection is tight. Some pipe fittings and equipment have their own stainless steel flanges, which also belongs to flange connection.
Flange connection is an important way of pipeline construction.
The stainless steel flanges connection is easy to use and can bear large pressure. stainless steel flanges connection is widely used in industrial pipeline. Generally speaking, the function of flange is to make the pipe connection fixed and sealed.
Precautions for use
1. In order to prevent the corrosion between the eyes caused by the heating of the stainless steel flanges 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 interlayer should be cooled quickly, and the narrow weld bead is suitable.
2. The welding rod should be kept dry when it is used. The titanium calcium type should be dried at 150 ℃ for 1 hour, and the low-a hydrogen type should be dried at 200-250 ℃ for 1 hour (it cannot be repeatedly dried, otherwise the coating is easy to crack and peel off), so as to prevent the coating from sticking oil and other dirt, so as not to increase the carbon content in the weld and affect the quality of the weldment.
3. When welding stainless steel flanges pipe, carbide precipitates under repeated heating, which reduces the corrosion resistance and mechanical properties.
4. Stainless steel flanges fittings, butt welding stainless steel flanges electrode has good corrosion resistance and oxidation resistance, widely used in chemical industry, fertilizer, petroleum, medical machinery manufacturing.
