Connection mode：
Adapter connection is the two pipes, fittings or equipment, first fixed in a wheel adapter, two adapters, with adapter pad, with bolts fastened together to complete the connection. Some pipe fittings and equipment have their own adapters, is also a adapter connection. adapter connection is an important connection mode in pipeline construction. The adapter connection is convenient to use, can withstand the greater pressure. Adapterd connections are widely used in industrial pipelines. In the home, the pipe diameter is small, and low pressure, can not see the adapter connection. If in a boiler room or production site, there are adapterd pipes and equipment everywhere.
Welding quality：
As iron plate welding adapter, many customers question is the quality of iron plate welding adapter is better than forging welding adapter. In fact, the quality of iron plate welding adapters is the same as that of forged welding adapters, but what exactly can not be guaranteed about iron plate welding adapters? That is, the material of iron plate welding adapters is the least guaranteed, because in the normal process, the density of the plate welding adapter is not a problem, but in the process of production, the blank of the plate welding adapter is rarely tested, so to speak, after the production, the material quality of welded iron plate adapters can not be guaranteed without testing.
Welding process：
Preweld preparation：
Check and debug equipment to ensure proper operation. 2. The electrode should be dried at 300 ° C-350 ° C for one hour.
Welding process：
Assembly of the vertebral body and large adapter according to the requirements of the Assembly drawings together, and then the large adapter is divided into an average of 8 equal parts. 2. Because the adapter is thicker and the groove is bigger, the welding adopts the segmented symmetry and multi-layer welding.
Points to note：
Bottom must use J506 electrode manual surfacing, and the use of small current welding. Welding in strict accordance with the welding process. 2, after each welding a position, should use a level ruler card adapter plane deformation. 3. Hammering the weld with Air Hammer while welding, in order to eliminate the stress.
wheel spacer：
Spacer is a kind of plastic deformation, and has a certain strength of the material made of the ring. Most spacers are cut from non-metallic sheets or are made to the required dimensions by specialized factories. In high-pressure equipment and pipelines, the use of copper, aluminum, 10 steel, stainless steel made of lens-type or other shape of metal gasket. The contact width between the high pressure spacer and the sealing surface is very narrow, and the processing smoothness between the sealing surface and the spacer is high.
