Stainless steel pipe fittings can be divided into two names. The understanding is that pipe fittings made of stainless steel have the characteristics of stainless steel. What kind of welding does it have? Stainless steel pipe fittings are a kind of pipe fittings. They are made of stainless steel, so they are called stainless steel pipe fittings. They include: stainless steel elbows, stainless steel tees, stainless steel crosses, stainless steel reducers, stainless steel caps, etc., depending on the connection method. Divided into four categories: socket stainless steel pipe fittings, threaded stainless steel pipe fittings, flanged stainless steel pipe fittings and welded stainless steel pipe fittings. Stainless steel elbows are used where pipe fittings turn; flanges are used to connect pipes and pipes to the end of the pipe. Stainless steel three-way pipes are used where three pipes are collected; stainless steel four-way pipes are used for four pipes. Place: The stainless steel reducer is used where two pipes of different diameters are connected. Main stainless steel materials: 304, 304L, 316|, 316L welded stainless steel pipe fittings (Stainless steel pipe fittings) are pipe fittings that insert a stainless steel pipe into the socket part of the pipe fitting and then perform argon arc welding in a circle along the edge of the pipe fitting. It is reliable in all connection methods Connection method. The inner diameter of the pipe fitting socket u003d the outer diameter of the pipe. According to the welding part of the pipe edge, it can be further divided into three kinds of pipe fittings: slope side extension, step side extension and no extension. The socket welding specification is generally DN15-DN100. Butt-welded butt-welded stainless steel pipe fittings are pipe fittings that are welded by argon arc welding along the butt seam of the stainless steel pipe and the pipe fitting. Generally, welding is required. Outer diameter of pipe fitting socket u003d outer diameter of pipe. Butt welding is generally used for welding of stainless steel piping systems with larger specifications. Compression-type pipe fittings have the characteristics of reliable and safe connection, convenient and quick construction, suitable for embedded installation, maintenance-free update, and relatively superior economic efficiency. The working principle of the compression fitting is to insert the thin-walled stainless steel tube into the socket of the compression fitting, and use a special compression tool to lock the stainless steel tube in the fitting. The cross-section shape of the compression fitting is hexagonal. There is an O-ring seal between the pipe fittings, which makes it have the characteristics of anti-leakage, anti-drawing, anti-vibration and high-pressure resistance. Therefore, it is a more advanced connector in direct drinking water system, tap water system, heating system, steam system, industrial oil pipe system and industrial gas pipe system. It is suitable for the connection of water, oil, gas and other pipelines. Manufacturing standard: GB/T 19228.1 2003 Nominal pressure: ≤1.6MPa Applicable temperature: -20℃ ~110℃ Applicable medium: oil, water, gas and other non-corrosive or corrosive media. Manufacturing material: stainless steel 304 316L piping: Φ15. 88～Φ108 stainless steel welded steel pipe quick-connect fittings plug-in self-locking circlip type pipe fittings fast flash-connect connection method is a plug-in self-locking circlip type connection technology, as long as the pipe is inserted into the quick-connect fittings, the quick flash connection can be achieved In addition, when disassembling, the pipe can be pulled out and removed as long as the quick connect pipe is clamped and strengthened with a matching light special tool. Quick flashing pipe fittings are not only more convenient and faster to install and disassemble, but also have excellent properties such as reusable, non-leakage, shockproof, and cushioning cold shrinkage and thermal expansion. It is a new exploration and breakthrough in pipeline connection methods. It has been widely used and verified in water supply systems at home and abroad. Among them, the pipe fittings are designated pipes by the Water Supplies Department in Hong Kong. Through the special high-temperature resistant rubber ring, the pipe fittings in the upper and lower water pipes of solar water heaters have gradually begun to be applied and recognized, making installation and use more convenient. I believe that in the future, there will be more new innovations and breakthroughs in pipeline connection technology, and it will continue to develop in the direction of convenience, speed, and humanity, and there will be more and more perfect products for human enjoyment.
