Q:Can the copper tube use a clip on pipe joint?
Clamping sleeve type pipe joint for copper pipe connection.Copper pipe connections are commonly used:
Q:How many types of hydraulic connections?
A hydraulic system in which the components between the high pressure tubing and the high pressure tubing are connected.
Q: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
Q:What are the specifications and models of metal hose couplings?
It is mainly used for connecting the box and hose in place. Open the box in the box and plug into the joint. The external thread joint is fixed with the lock. 2, mainly used in screw thread connection cable pipe and hose.
Q:What are the types of hydraulic couplings?
The main domestic A, B, C and H, A type is most common,
Q:The difference between expanding, clamping sleeve and welding pipe joint
Sleeve type pipe joint: the working principle of the clamp sleeve is to insert the steel tube into the clamp sleeve, lock the sleeve with the nut, contradict the sleeve and cut into the pipe to seal. The utility model does not need welding when connected with the steel pipe, and is favorable for fire prevention, explosion prevention and high-altitude operation, and can eliminate the defects caused by careless welding. Therefore, it is a kind of advanced connecting device in pipeline, automatic control device, pipeline, oil refining, chemical, petroleum, natural gas, food, pharmacy, instrument and meter, etc.. Apply to oil, gas, water and other medium pipeline connection. The card connector has reliable, high voltage capability, high temperature resistance, good sealing and repeatability, installation and convenient maintenance, safe and reliable connection.
Q:What is the liquid used in the fire hose joint?
Most of the interfaces used for the groove connection are diluted detergent or soapy water
Q:Hydraulic pipe quick coupling principle of hydraulic pipe joint
JB/T6381 ~ 6385-1992 burking hose connector has the advantages of convenient installation, but added a tightening process. 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 ~ 50 degrees Celsius; water, 80 degrees below JB/ZQ4427 ~ 4428-1986, three valve type hose joint assembly, do not need to remove the rubber tube of the outer layer. A slightly different diameter of hose hose, hose on the joint coat of pre compression to compensate. Hose pre compression in 31% ~ 50% range to ensure no leakage under the pressure of work, will not pull glue, cover does not break. With the welded pipe joint, quick joint, sleeve type pipe joint used for oil, water and gas pipeline system for medium, working pressure, medium temperature by connecting hose limited JB/ZQ4429 ~ 4431-1986 quick change connector (both open and closed) tube apart and self sealing pipe. In the liquid will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex, and the local resistance loss is greater. Suitable for oil and gas pipeline system for medium, the working pressure is lower than 31.5MPa, the medium temperature of -20 to 80 DEG JB/ZQ4434-1986 quick change connector (both ends open) for oil and gas pipeline system for medium, the working pressure of medium temperature according to connecting hose limited JB/ZQ4435-1986

Q:What do you mean by "s" in the standard of pipe joint?
In hydraulic couplings, the S denotes the heavy series, L denotes the light series, M denotes metric threads, and R stands for English threads
