Q: Do I need a shim for the flat metal hose joint?: If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.

Q: How to determine the parker381 hose joint?: Parker 381 series hose comes with Parker 43 series hose connector. Because the type, material, and surface treatment of hose joints are indistinguishable from the naked eye, these factors directly affect the quality of the hose assembly:1., if the factory internal judgments, according to Parker provided geometric parameters to determine;2., if purchased on the market, it is best to choose Parker authorized dealer (Parker authorized dealer has Parker's power of attorney);

Q: What's the difference between the rubber hose joint and the stainless steel hose joint?: Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The Shanghai Xia Xia brand rubber joint is a kind of rubber connector. It is a kind of hollow rubber product used for flexible connection between metal pipes. By connecting the way loose, flange, fixed flange and thread type 3; according to the structure can be divided into single sphere, double sphere, different diameter body, bending sphere and fan coil 5. It consists of inner and outer rubber, polyester cord and steel ring. It is formed by the combination of high temperature vulcanization and metal flange or parallel joint.

Q: Is it feasible to use rubber material, middle canvas layer and outer rubber material in PVC rubber tube?: Improvement measures: 1, adjust the process, plastic material in place; mixing rubber plastic stability; vulcanized rubbing with low temperature long time vulcanization; 2, test cloth in curing temperature shrinkage coefficient is too big, consider changing cloth;

Q: The main features of Linatex rubber tube or what are the characteristics?: The main characteristics are excellent wear resistance, high impact resistance, high pressure resistance

Q: What is negative pressure rubber shock proof joint? Is vacuum piping available?: With high pressure, good elasticity, large displacement, balance pipe deviation, absorbing vibration and noise reduction effect, convenient installation, but also can greatly reduce the noise and vibration of the pipeline system, which can solve all kinds of line interface displacement fundamentally, axial expansion and concentricity problems, mainly installed in the pump inlet the vacuum pump inlet, or large, can solve the 100% rubber joint suction flat phenomenon.

Q: What kind of rubber hose does not leak the smell of liquefied gas?: It is recommended to use stainless steel bellows instead of rubber hoses

Q: Installation of rubber flexible joint: Flat, vacant, vertical installation of rubber joints, supporting force of pipeline working pressure less than the axial displacement of the rubber joint, you should install anti pull off device, to prevent the work pressure.

Q: What are the standard numbers for hose couplings? What standards are they used to accomplish?: Standard number GB, according to national standards to complete.

Q: Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?: It is relatively rare, usually corrugated pipe for zinc metal corrugated pipe, the construction unit may be in order to prevent pipe blockage, when pouring concrete, the corrugated pipe with rubber tube, after pouring completed final setting, you can pull out rubber tube. Bellows need not be drawn.
