Q:What should I pay attention to when rubber tube is in storage?

The phenomenon of natural vulcanization caused by long-term exposure to corrosive gas or prolonged exposure to sunlight is called aging of rubber. The main phenomena are increasing of self weight, volume expansion and strength reduction.

Q:What do you mean by "DN" on hydraulic hose?

Hydraulic hose temperature: -40 ~ 120 DEG C, product specification range: DN2.5mm ~ DN305mm.

Q:Is there a tolerance standard for rubber tubes in length?

Generally speaking, the requirements of diameter and wall thickness are more stringent.The diameter is usually the inner diameter of the hose.Generally speaking, the length is not high, and the unwritten rule for foreigners is "+ 2~3mm".

Q:Flex rubber joint installation skills, what are the materials of rubber soft joint?

Flexible rubber joint is normal for medium temperature of 0-60 DEG C usually water medium such as oil, acid, high temperature and other corrosive and texture should be selected under the peace situation should be relatively Tenai data can not be blindly on rubber joint or universal.

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:Toilet hose and water tank joints leaking, how to repair?

No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.

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

When the joint is made into a quick plug, hard pipe is rare; for example, galvanized steel pipe, joint practice is similar to hydraulic tubing. The pipes in the compressed air are welded with steel tubes, but I don't think that's what you call the hard tube

Q:What is the rubber sleeve flange connection sleeve?

Rubber flexible joint flange connection sleeve flange gate valve quota.

Q:My company does high-quality rubber tube, all of the core method, and why use EPDM to do the inner tube, it is difficult to take off the core, please point out! What's the reason?

The core needs to be removed, and if it is too long, the mandrel can be divided into two sections and separated from the 2 sides

Q:What happened to the soft rubber flat?

Rubber soft joint is a common rubber telescopic device". The inner pressure of the pipe or the equipment, because of the decrease of temperature or the venting of the vertical section, causes the internal negative pressure.
