How was the pipe joint named?
Clip type pipe jointThe utility model has the advantages of advanced structure, good performance, light weight, small size and convenient operation, and is widely used in the hydraulic system. Working pressure up to 31.5MPa, requiring high dimensional accuracy of the pipe, cold drawn steel pipe is required. The card sleeve is also of high accuracy. Piping systems for oil, gas, and general corrosive media, tables 15~26, GB3733.1 to 3765-1983
Hydraulic hose, high pressure ball valve, special quick joint, clip type pipe joint, welded pipe joint, high pressure hose. Transition type pipe joint, clamp type pipe joint, three type pipe joint, non-standard pipe joint, flared pipe joint, right angle pipe joint, rotary pipe joint, quick joint, stainless steel pipe joint and copper joint.Welded pipe jointPipe welding with nozzles. The sealing surface of the O sealing ring is sealed between the joint body and the pipe. The utility model has the advantages of simple structure, easy fabrication, good tightness and low requirement for the dimension precision of the pipe. High welding quality, inconvenient assembly and disassembly. The working pressure is up to 31.5MPa and the working temperature is -25 to 80 DEG C. It is suitable for the piping system with oil as the medium. Table 6~14 JB966 to 1003-1977
Use the end extension of the pipe for sealing without any other seals. The utility model has simple structure and is suitable for the connection of thin-wall pipe fittings, and is suitable for pipelines with low pressure of oil and gas as medium. The pressure is allowed to be used in table 41, table 27~41, GB5625.1 to 5653-1985Insert welded pipe jointThe length of the tube will need to be inserted into the pipe joints and pipe end until the connector end of the contact, the pipe and the pipe joint are welded together, can save over, but the pipe size is strictly applicable to oil and gas as the medium pipeline system table 43 ~ 49 JB3878-1985Cone seal welded pipe jointOne end of the connecting pipe is provided with an outer cone surface, and a O shape sealing ring is matched with the inner cone surface of the joint body, and is screwed with the screw thread. The working pressure is 16 ~ 31.5MPa, the temperature - 25 to 80 DEG C for oil as medium piping system table 50 ~ 62 JB/T6381 ~ 6385-1992Withhold hose connectorThe installation is convenient, but a tightening process is added. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air -30 to 50 degrees Celsius; water below 80 degrees JB/ZQ4427 ~ 4428-1986
