How many kinds of stainless steel flanges are there? What is the performance

The performance of stainless steel flanges. Stainless steel flanges will not produce corrosion, pitting, rust, and are not easy to be worn. Stainless steel is one of the materials with higher strength among the metal materials used in construction. Because stainless steel has good corrosion resistance, it can make structural components maintain the integrity of engineering design for a long time. The chromium-containing stainless steel stamping flange also integrates mechanical strength and high extensibility, easy to process and manufacture parts, and can meet the needs of architects and structural designers. All metals react with oxygen in the atmosphere to form an oxide film on the surface. Sales of stainless steel flanges and other steel butt-welded pipe fittings, forged pipe fittings and steel flanges. The main products are carbon steel, austenitic stainless steel and alloy steel and other domestic and foreign high-quality pipe flanges, elbows, and tees ( Four-way), same (eccentric) reducer (small head), elbow, pipe cap, forged socket welding and threaded pipe fittings. All products adopt American standard ASME (ANSI), German standard DIN, Japanese standard JIS, Chinese GB/T, JB, SH, HG and other standards. At the same time, various special, non-standard, and special thick walls can be made according to customer requirements. Series of stainless steel pipe fittings, stainless steel flanges and other pipe connections. How many kinds of stainless steel flanges are there? Flange type: stainless steel butt welding flange with neck butt welding ring Diameter flat flange with neck butt welding flange large diameter high neck flange socket welding flange eight-shaped blind plate threaded flange butt welding ring loose sleeve flange flange cover rotating flange surfacing / overlay welding flange anchor flange Matters needing attention when using stainless steel butt welding flange. 1. When using welding technology, the current passing through should not be too large. Under normal circumstances, it should be controlled at 20% less than the welding rod, and the arc should not be too long during operation. As for the rapid cooling between layers, narrow welding bead can be used. Technology. As long as the above conditions are avoided, the stainless steel butt-welded flange will avoid corrosion. 2. The electrode used must be kept dry. If necessary, drying can be used to keep the electrode in a dry state of use. However, the stainless steel flange manufacturer should remind that the method of drying can not be repeated, it is good to keep the strip in a dry state to avoid the phenomenon of peeling of the evil spirit. Third, the stainless steel flange manufacturers should emphasize that after the chromium stainless steel adopts butt welding method, there will be a relatively large hardenability American standard, and this will be prone to cracks. If the same type of welding rod is used for welding, the preliminary work that needs to be done is to preheat and then do the cold treatment to ensure the normal use of the welded flange.
