Q:May I ask what material EN39 is? Used to make a threaded pipe joint
Groove connection: This is the most advanced connection mode at present. There are two two connecting pipes, valves, or pipes and valves that are connected by clamps. In the outer pipe or valve connecting end have an annular groove manufactured according to the standard, when connected with a supporting clamp. Site construction, installation and disassembly are very convenient and quick. Not only the seal is reliable, but also saves time and material. It has incomparable advantages in large caliber connection.

Q:What are the standards for the pipe connections at both ends of the cone pipe?
A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
Q:How many types of hydraulic connections?
Mechanical design manual fourth volume hydraulic pipe joint that part has detailed introduction and each installation size, and comes with the picture Oh, a glance will understand, hope to adopt Oh!
Q:Classification of pipe couplings for hydraulic couplings
Hydraulic hose, high pressure ball valve, quick joint with odd intention and sleeve type pipe joint
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
The position of the station is wrong, the output is not working / the spanner angle is not right... The most simple, is to find a major wrench with a long handle and then force that, if the screw is not open, it may break pipe head, we should pay more attention to the....
Q:What is the manual pre assembly procedure for the EO-2 joint?
I. pre assembled1, EMB card sleeve type pipe joint pre assembly of the most important link, directly affect the sealing reliability. 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. I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent.
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches1/2 inches, usually read as "four thiophene"".
Q:The gas cooker joint is pagoda shaped. Can it fall down and connect with bellows joint directly?
The provisions of China's domestic gas (gas interface with connection terminal interface), must be 55 degree cylindrical internal thread sealing pipe thread and external tapered thread sealing pipe thread, 55 degree conical internal thread and external tapered thread, 55 degrees of one of three non sealing pipe thread.A bellows is a tubular elastic device that is joined by folding wrinkles along a folded and telescopic direction. Bellows joints for civil water pipes and gas appliances are mostly 55 degree non hermetic pipe threads.Because the form of pipe joints is very large, they can be used in conjunction with the same thread and sealing form, so it is not sure whether the joint of the pagoda can be dropped or not.
Q:Specification for thread of gas couplings
3, pneumatic connectors, foreign brands are more well-known SMC, domestic brands are commonly used, SNS, TPM.4, pneumatic joints commonly used series are PCH, PCF, PL, PLF, PB, PD, PX, SL, PH and so on
