Stainless steel pipe fittings are made of stainless steel, so it is made of stainless steel pipe, which contains: stainless steel elbow, stainless steel tee, stainless steel, stainless steel reducer, stainless steel tube cap, etc. According to the connection method Divided into socket-type stainless steel pipe fittings, threaded stainless steel pipe fittings, flange stainless steel pipe fittings and welded stainless steel pipe four categories. Stainless steel elbow for pipe turning place; flange for the pipe and pipe interconnected parts, connected to the tube end, stainless steel tee for three pipe collection place; stainless steel pipe for four tube collection Place; stainless steel reducer for the different diameter of the two pipes connected to the place. Main stainless steel Material: 304,304L, 316 |, 316L
Stainless steel pipe fittings are all kinds of stainless steel pipe connection works collectively, according to the shape, use, connection, etc. are divided into different categories. It is easy to install, high performance, durable and so on, in a variety of pipeline construction and installation has a wide range of applications.
Stainless steel pipe fittings can be divided into stainless steel tee, stainless steel flanges, stainless steel head, stainless steel elbow, stainless steel cap, stainless steel head and so on.
Iron and steel are different in terms of carbon content. Carbon content of less than 2% iron and carbon alloy is steel, carbon content of more than 2% is called iron. Steel because of both toughness and flexibility and rigidity, is widely used. Life is exposed to steel, but people are called different. For stainless steel, regardless of whether the magnet sucked or not, as long as consistent with its quality standards, are stainless steel.
How can we connect to the ordinary people who have not come into contact with this special type of work, only engaged in such industry professionals will often contact, so we generally know little about this, for you to open the fused The mystery of the pipe connection.
PE welding process
1. Measure and mark the depth of the pipe or the welding area (such as the saddle type pipe) on the pipe with a marker. Note: The pipe end should be cut off perpendicular to the axis.
2, such as the pipe is not perpendicular to the shaft when the cut off, it will lead to part of the PE welded pipe welding area exposed, resulting in molten material into the pipeline and other welding errors.
3, PE pipe after a period of storage, it will form an oxide layer on the surface. Welding must be near the welding area of the oxide layer completely removed otherwise it will affect the quality of welding, resulting in security risks.
4, remove the pipe inside and outside the surface of the edges and shods.
5, PE welded pipe fittings and PE pipe welding surface must be absolutely clean, dry, no grease in the scraping off the oxide layer, the installation can be used before the polyethylene-specific cleaning agent or more than 96% alcohol and colorless paper clean clean The
6, welding should be carried out after the complete decontamination of the cleaning agent, pipe welding area clean, should be inserted into the depth of PE fuse parts re-logo.
7, PE welded pipe welding end of the connector into the pipe to the limit of the shoulder or the main pipe has been marked on the depth of the installation should pay attention to the pipe fittings power outlet in a convenient location, the pipe must be under stress conditions and The pipes are installed together. If the pipe diameter deviation is too large, should be scraping the surface of the pipe welding to fit fit again.
8, in the absence of stress conditions installed under the electric fused pipe, can be turned by hand, if not installed in the absence of stress conditions, welding will appear when the melt overflow pipe fittings or overflow into the pipeline such accidents.
9, power connection should pay attention to the use of voltage and input cable cross-sectional area. Connect the welder plug to the tube jack and accurately enter the welding time and the cooling time on the pipe. After the above preparations are ready, press the Enter key, the welding machine will again display the welding parameters, fully confirmed, then press the start button to start welding.
