Q:In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?

In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?

Q:Do I need a shim for the flat metal hose joint?

If one of the two interconnected joints is one of those with a groove and a O ring, it would be better to put the O ring in it and seal it better.

Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.

The pressure of the aluminum pipe is relatively small. "Again, when the aluminum pipe is too soft, it is easy to be flattened.".. Rubber tubes will decay if they are used! Withstand pressure is also high!

Q:How can we prevent the aging of rubber tubes?

Formula design is the most important. Rubber formula design is directly related to the service life of the product!

Q:Can the spring hose joint be connected to the tap?

You don't know what is the use of the material pipe, generally divided into PB and PPR, two kinds of pipe welding temperature requirements are not the same, so don't listen to others with the same welding machine can speech, it is extremely irresponsible.

Q:How can the rubber tube be used properly and how to use it properly?

Hose selection and installation caused by improper hose rupture. When replacing the hose, the hose wire length, number, shape and size of the joint should be reasonable, and should try to reduce the degree of bending in the hose; tighten union nut, do not make the hose distorted, excessive bending and twisting will reduce the service life of the hose greatly; some easily friction parts should take protective measures to prevent the hose due to wear and burst.

Q:Production process and raw material of rubber

Raw materials: all kinds of rubber, rubber compounding agent, as well as the fiber and metal skeleton materials.

Q:Hydraulic hose joint configuration

The utility model relates to an ultrahigh pressure drilling hose joint: an ultrahigh pressure drilling hose joint used on an oil field mining device, which comprises a sleeve and a connecting section which is connected with the core rod ring sleeve. The inner hole of the sleeve and the outer round surface of the core rod of the connecting section are correspondingly matched in turn, and the utility model is connected with an anti pulling out section, a sealing section and a transition section. Both the stripping section and the sealing section are respectively provided with a plurality of annular grooves on the excircle surface of the inner hole of the sleeve and the core rod, and are matched with or matched with the bulge. The test shows that when the working pressure of the inner cavity of the hose is 70MPa, the pulling resistance and the tightness of the hose joint can still be effectively guaranteed. The joint of the hose is welded because of the high temperature generated by the welding, and the locking of the sealing adhesive layer of the inner cavity of the rubber tube is effectively prevented from tearing by the locking of the transition section. Compared with the prior art, the production failure of the hose joint is eliminated, and the service cost is obviously reduced.

Q:What's the difference between hose and hose for compressed air?

In use, it is usually marked with color. For example, the intake is made of blue, and the exhaust is made red, but it is not necessary.

Q:How can I connect the gas tank connection hose?
