Product Name：Stainless Steel DIN Cover Flange
The company pursues the accuracy and refinement of manufacturing, and constantly improves its lean manufacturing equipment, including every component. The company strictly implements ISO, GB, NB, JB, HG, AISI, ASTM, JIS, BS and other production standards. Carefully built to ensure the high quality of the products. High-quality, sophisticated and sophisticated modern equipment has laid the foundation for high-quality products. In order to serve customers with high-tech products, Chuxin has invested heavily in the introduction of high-precision production equipment and processes.
Flange cover is also called blind flange and blind plate. It is a flange with no hole in the middle for sealing the pipe plug. The function is the same as welding head and screw cap, except that blind flange and screw cap can be removed at any time, while welding head is not. There are many types of sealing surface, including plane, convex, concave convex, mortise and groove surface, and ring connection surface.

Assembly and welding operations of stainless steel flanges
Due to the processing error sometimes the gap is too large, and the welding is easy to burn through. The disposal method may overlap the local (individually 3~5mm) surfacing layer on the stainless steel flange pipe, and the machining to 0~0.05mm Gap or craftsmanship. If it does not fit, the outer diameter of the straight flange pipe should be small or ground.
1. Welding parameters: Welding current 25～30A, maintenance air flow 4～7L/min.
2. The arc starting must be carried out on the flange tube length. The arc should be on the thick tube. The outer arc flame is used to heat the ripple tube, and the edge of the ripple tube is blocked with a welding wire, and the molten stainless steel welding wire is used to melt the ripple tube.
3. The welding time must be carried out on the thick pipe length, and short weld or spot welding should be used for welding.
4. When welding, always observe the melting of the ripple tube. Individually melt 1 to 3 molten pools. It is not suitable to continue welding, especially when the gap is large, it is easy to burn through.
Stainless steel flanges generally have strong sealing, tensile resistance, bending resistance, compression resistance, etc. According to various properties, stainless steel flanges can also be divided into socket welding flanges, loose flanges, and butt welding Steel flanges, integral flanges, flat welded steel flanges, etc., each stainless steel flange has its own product parameters, here are the details to share with you.
