For fused pipe fittings, we say that the common way in life is to apply in the industrial field, and compared to these industrial raw materials, it also has great advantages in industrial raw materials. First of all, look at the appearance It is very beautiful and beautiful, and also has a better advantage by virtue of its good structure. Therefore, the pipe fittings also have great advantages in general, and the working principle also needs us to understand.
Generally speaking, electric fusion pipe works mainly through the Joule effect. The mutual conversion of heating elements is used to convert the electrical energy into thermal energy. At the same time, due to the stability of the pipe, the pipe has a great advantage in use. Eliminate waste
What are the common welding methods? A method of processing the workpiece by combining it with heat or pressure, or both, and with or without filler materials, is called welding. The workpiece can be made of various similar or different types of metal and non-metal materials (plastic, graphite, ceramic, glass, etc.), as well as a metal and a non-metal material. Metal welding has a wide range of applications in modern industry, so narrowly speaking, welding usually refers to the welding of metal materials.
According to the state of the metal materials during the welding process, the welding methods are currently divided into the following three types: ⑴ fusion welding In the welding process, the welding joint is heated to a molten state, and the method of welding without pressure is called fusion welding. Common welding methods include arc welding, gas welding, and electroslag welding. ⑵Pressure welding During the welding process, pressure must be applied to the weldment (heated or unheated) to complete the welding method is called pressure welding. Common pressure welding methods include resistance welding (butt welding, spot welding, seam welding), friction welding, rotary arc welding, ultrasonic welding, etc. (3) During brazing, a metal material having a lower melting point than the base metal is used as the brazing material, and the welding piece and the brazing material are heated to a temperature higher than the melting point of the brazing material and lower than the melting point of the base material, and the base material is wetted with the liquid brazing material The method of filling the joint gap and interdiffusing with the base material to achieve the connection welding is called brazing. Common brazing methods include flame brazing, induction brazing, furnace brazing, salt bath brazing, and vacuum brazing.
Fused pipe fittings
Interface: plastic drainage pipe socket rubber ring, bonding, welding, clamp and other connection methods, should be selected according to the nature of the pipe material and the size of the pipe diameter. Concrete and reinforced concrete pipes have four types of joints, such as rubber rings, steel mesh cement mortar tape, cast-in-place concrete collars and expanded cement mortar, which should be determined according to the nozzle form and other factors; cast iron pipes can use rubber ring flexible joints and cement Mortar joints; steel pipes should be welded joints; flexible joints should be used for sewage and confluent drainage pipes; when pipelines pass through silt, fine sand layers and under high groundwater levels, or when the seismic fortification zone is 8 degrees, the joints should be used Flexible interface.
