Q: Why should the high pressure hydraulic tube peel off the outer skin?: Reasons for stripping:1, the inner diameter of the sleeve is a standard series, and a little rubber hose is not suitable for sizing.2, after stripping, the sleeve can be directly pressed on the steel wire layer, the connection is reliable, and it is not easy to pull out.

Q: What is the maximum pressure that a hose can bear?: Of course, there is a super high-pressure hydraulic hose, the working pressure of up to 80MP., using 6 layers of steel wire or more winding process.

Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?: If the gas is longer, to Caution! Protective tube wall, as far as possible, to prevent accidental damage risk of gas pipe.

Q: How to distinguish the true and false corrosion resistant rubber soft joint?: Put the rubber joint in the corrosive liquid which needs to pass. One day, 24h can see that the swelling ratio is not more than 5%!

Q: How do you remove the burrs on the rubber joint quickly?: Frozen deburring machine is a kind of ultra low temperature using liquid nitrogen to make rubber, plastic products, zinc alloy burr occurs rapidly embrittlement, and under this condition, the burr of high-speed jet impinging particles of frozen products, so as to achieve both high quality and high efficiency removal products of burr, and keep possession the product itself does not change. The utility model can greatly improve the deburring precision of products, and has a high degree of intensification.

Q: HDPE double wall corrugated pipe joint shall be made of elastic sealing rubber ring and socket joint interface. What are the requirements for rubber ring joint?: When the interface is made, the inner wall of the bearing mouth is cleaned first, and the lubricant is coated on the inner wall of the socket and the rubber ring of the socket, and then the central axis of the socket face end is aligned.

Q: Installation of rubber flexible joint: The pipe must have a fixed support or fixed bracket, and the force of the stationary bracket must be greater than the axial force. Vertical installation and overhead installation products both ends need to install the corresponding fixed bracket and force support, to prevent the compression of.

Q: What material is the rubber joint used in the desulfurization pipeline? What's the difference?: The desulfurization pipeline can be used with three yuan EPDM rubber ring joint, and PN4-6 is no problem.Generally, the desulfurization pipeline is weak acid base.

Q: The pipe of the gas water heater is buried in the wall. It is made of nylon tube and rubber tube. Is it possible to use rubber tube?: With respect to the through wall gas safety management regulations, it is clear that hoses can not be used through walls.

Q: What are the standard numbers for hose couplings? What standards are they used to accomplish?: The general hose inside and outside the adhesive layer material with natural rubber, styrene butadiene rubber or butadiene rubber; hose with chloroprene rubber, nitrile rubber; acid and alkali resistant, high temperature resistant hose with ethylene propylene rubber, fluorine rubber or silicone rubber etc..
