Q:How to detect the reliability of rubber hose

Hose size measurement: the inner and outer diameter, outer diameter, wall thickness, enhancement layer concentricity, inner and outer layer of glue thickness, assembly diameter, new GB and ISO increased the length and the measuring point mark, provides no pipe joint and a hose length of various pipe joint measurement method.

Q:Access toilet water inlet hose joints, how to repair water?

You try to put the connector aside, hold some force in the toilet hole, or add a person to press it with your hand, then swivel the pipe joint and maybe open it.

Q:Do you need a hose connection to connect the ventilation pipe to the exhaust fan? Under what circumstances? Under what circumstances?

Ventilation ducts and exhaust fans are for people or things, and the noise of vibration is unbearable for people or things.

Q:What is a hose valve?

It is composed of valve body, headstock gear and special rubber tube. When working, turn the handwheel in clockwise direction, which can achieve throttling and closing.

Q:Carbon dioxide gas shielded welding torch wire feed hose joint, that steel wire can not be drawn out, how to solve it, with welding?

Replaceable welding wire feeding tube wire feeding tube can be directly removed, if not directly pull out, it may be the welding current and wire melting welding in together, there may be a wire feeding tube after the corrosion resistance increases to pull out, encountered such a situation like a gun only;

Q:Automotive applications of rubber hose

Mainly connected to the engine and air filter, engine and radiator systems, automotive air-conditioning systems. As part of its intake from the engine, close, so high temperature resistance, oil resistance, corrosion resistance, aging resistance, low temperature resistance, the material has many types according to the different processing techniques, such as NBR nitrile rubber is widely used in vacuum brake pipe, good oil resistance rubber content is high, but relatively resistant to ozone poor;

Q:Difference and application of rubber joint and rubber expansion joint

Because the material of rubber expansion joint is higher than the price of ordinary rubber, the price of rubber expansion joint is naturally higher than that of our common rubber joint. The so-called "one point price", "goods", the user in the choice of rubber expansion Festival at the same time, must be based on the use of media to select materials. High quality rubber expansion joints are usually made of butadiene styrene rubber, while SBR is the earliest synthetic rubber. Because it is developed with reference to natural rubber.

Q:Acid burette and burette why different structure

The basic buret cannot use frosted glass, like a night can produce sodium silicate, lead glass cock is stuck and can not rotate. With smooth glass beads with rubber tube, you can play a sealing role, the use of a little skill, pinch the rubber tube, in the upper part of the glass bead force, resulting in a gap, let the liquid drop out. If pinch in the lower half, it will lead to the lower end of the glass tube bubble, the amount is not accurate. Burette after use must be washed with water.

Q:What does rubber soft joint "KDTF" mean?

It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The main outer layer, inner layer, intermediate layer reinforced polyester cord fabric, steel wire pressure protection layer.

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.
