Q:Man, can you send me some national standards? Mainly for hydraulic use
Domestic standards, I do not have any standards, the domestic standards of learning German, learn from other countries standards, do very badly.SN standard pipe taper angle of 24 degrees and 30 degrees in China, can not mix.
Q:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Flexible pipe joint and flexible pipe joint difference, the difference is relatively large, the formulation with the domestic standard, causing confusion in the market there are three main points of differentA, the flexible pipe joint is the power plant smoke pulverized coal pipeline, the flexible pipe joint is coal construction design institute, the two products are used in different occasions, one is a high pressure resistant, high angle high the amount of compensation.
Q:What material does the hydraulic pipe joint use? Carbon steel or cast iron?
Special requirements made of stainless steel or copper.The US has 37 degrees and 74 degrees. The cone and cone are fine teeth.
Q:What kind of tubing connections do you have?.
According to the number and direction of the connection, there are straight through, right angle, three pass and other types. The connection with the body has threaded connection, flange connection and so on. In addition, there are some special purpose pipe couplings.
Q:What are the types of tubing and pipe couplings?
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc..
Q:What's the hydraulic pipe joint material?
Selection of pipe joints, the minimum is equal to the entire hydraulic system working state of the maximum working pressure setting the maximum working pressure for each joint, not only to consider the pump outlet pressure, also consider starting pressure relief valve. Therefore, in the design of complex hydraulic pipeline, the actual pressure is best measured by field measurements. The system operating pressure has been fixed, so the maximum working pressure of each selected pipe joint shall be checked.The maximum working pressure of the pipe joint can be changed by different sealing methods or according to the change of temperature: similarly, if the pipe joint chooses the elastic seal, it will get higher working pressure than the rigid seal.International standard set 4 times insurance coefficient, the reason is the practice of design thinking, the error of pipe joint device and equipment operation process may appear, the working condition of the system stability, in order to guarantee the system not paralyzed when in operation, so the insurance coefficient of the nominal pressure of the high.
Q:What does pipe joint "DD" mean?
The strengthening pipe joint is a medium strength cast iron, which has good casting performance, simple process and small casting stress
Q:What are the differences between hydraulic couplings and fittings and elbows?
Connector: when the pipe joint and the equipment are connected, the connection mode does not match or needs to be changed, and the task is finished by the connector body. One end of the joint body is connected with the pipe joint, and one end is connected with the equipment.
