Q: What do you mean by "DN" on hydraulic hose?: DN stands for nominal diameter. The standard diameter after standardization, the midpoint between the inner diameter and the outer diameter, in units mm.

Q: What is the essential difference between silicone tube and rubber tube?: Silicone tube 100% non-toxic, tasteless, fine silk, silicone silicone tube (article), high pressure resistant silicone tube, silicone tube, gear shaped sealing strip, shaped article, food grade (non-toxic) silicone tube (article), medical silicone tube, silicone tube, silicone tube medicinal woven (used for conveying working pressure, liquid food, pharmaceutical and biological products. ) medical silicone pipe joint, silica gel sealing tube, flame retardant tube (strip), silica gel foamed pipe (strip), high temperature resistant silicon rubber tube, performance: cold resistance, high temperature resistance. Harmless non-toxic and tasteless; suitable for small household appliances (coffee pot, kettle, electric iron, electric cooker, frying pan, disinfection cabinet, drinking machine, pulp machine, bread machine, gas cooker, water heater) and electronic, automobile, medical and other mechanical products.

Q: What are the types of cable metal hose connections?: Mainly used for internal thread connection pipe and the hose thread cable.

Q: How can the soft joint of the pipe be elongated during use?: When the old pipe replacement of new products, old pipelines have the original pipeline flexible joint elongated, elongated here not just elongated, but when the pipeline working every day to pull long, long time, deformation is big.

Q: What is negative pressure rubber shock proof joint? Is vacuum piping available?: Negative pressure resistant rubber shock joint is simple product requirements than the general negative pressure resistant rubber joint rubber joint is much higher, simply can't stand the pressure, for example the pipe diameter is 0.1kg pressure, rubber tube will suck flat, so with the outward pressure pipeline is completely different, negative pressure, diameter must be increase the pressure guide tube, negative pressure diversion tube also is what we usually say is a carbon steel pipe in the shock absorber rubber hose diameter, but joint diameter than the original diameter, the pressure guide tube, shock absorber rubber hose will not be sucked flat, so that the original vibration isolation and shock proof box the expansion effect is not affected, only the affected joint is slightly smaller diameter.

Q: High pressure hose crimping connector, pressed on what position can effectively prevent the head off?: High pressure hose crimping connector, pressed on what position can effectively prevent the head off, need professional technology, you can find professional installation.If the burst pressure is greater than the standard 4 times the work pressure, even the qualified hose.

Q: How about rubber transfusion hose?: The last step is to protect the sulfide layer to remove the wound hose and then taking care, and pipe fittings withhold, then you can test the pressure sampling

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: Are the bridges, bellows and rubber tubes drawn out or are they drawn only? And the bellows are tensioned with the steel strand?: The bellows are buried inside the component and do not need to be pulled out. Through reinforcement, only pre-stressed, without tension bellows. When tensioning anchor is completed, grouting work is necessary.

Q: How to identify the quality of rubber pipes for sewage treatment?: 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.. Structure: hose structure is usually divided into inner layer, outer layer and skeleton layer (or middle layer). The inner layer directly bears the abrasion and erosion of the conveying medium; the outer rubber layer protects the inner part of the hose from the damage and erosion of the external environment; the stock price is the pressure bearing layer of the rubber tube, and gives the strength and rigidity of the tube body. The working pressure of the hose depends on the material and structure of the skeleton.
