Q:Is the trachea connected directly to the inside and outside threads? I remember a sealing ring
Pipe joint with advanced structure, good performance, convenient use, no welding, no piping will flare and a series of advantages, therefore, sleeve type pipe coupling has been widely used in various types of machinery, hydraulic pneumatic system. But the card sleeve pipe joint is made of higher precision, because of the complex process, it should not be scattered or small batch manufacturing, need professional production.Joint is generally divided into two types, plastic joints and metal fittings, plastic joint production of low cost, simple manufacturing process, and the pressure is only 1 MPa, metal joint complex production process due to the use of the material requirements, so expensive, the high temperature resistant, metal fittings, some high requirements of the environment the preferred
Q:What's the meaning of the pipe joint 14-M18*1.5? What's the thickness of the wall?
The assembly of the sleeve type pipe joint (1) the most important part of the pre assembly of the sleeve type pipe joint directly affects the reliability of the seal. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns.
Q:How about the water pipe fittings and millimeters?20mm is 425mm is 6Why
20mm is not a scientific argument.Should be the plastic pipe, the nominal outer diameter of DN20 plastic pipe, only corresponds to 4 points of the metal pipe threadThree,If it is a metal tube, it should be nominal diameter Dn15, and the corresponding English pipe thread is 6
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:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
Will affect the cooling effect, it is recommended to cut off the connector, and then use reaming device to expand after re installation. Charges will not be too high, dozens of blocks enough to be careful to be pit.
Q:How to choose the connection mode of clamp type flexible pipe joint correctly
Pipe end connections do not need to be done to the end of the pipeThe pipe end connection omits the overall length of the pipe and reduces the costThe overall price of the clamp joint at the end of the pipe is higher than that of the steel ringThe steel ring adopts the way of socket welding, and has certain requirements for the welding positionThe steel ring requires cleaning of the pipe port, i.e., the sealing surface
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
I've seen a lot of discussion about the NPT thread's stress levels, and none of them are accurate.He who knows knows not to answer. It took time to find relevant global requirements. For your reference
Q:What is the function of the pipe joint?
Hydraulic term is a part of a hydraulic system that connects the pipe or sets the line to the hydraulic element
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
Theoretically, the pressure is related to the design pressure of the joint and the maximum tolerable pressure of the steel tube manufacture.
Q:How to distinguish the type of tubing joint?
The oil pipe connection depends on what standard. It is convenient for you to contact me. Jensenshi@126.com. specializes in this thing.
