Q:The difference between silicone tube and rubber tube

First of all, we can find the difference between the material of silicone rubber tube and rubber tube. Smell it with your nose. Silicone doesn't taste. Rubber has a flavor. Silicone is generally more flexible, and rubber is more mechanical.Silica gel tube has high and low temperature (-60 ~ 200 DEG C), environmental protection, non-toxic, excellent heat aging, ozone aging resistance, light aging and aging resistance, soft, arc resistance, corona resistance.

Q:Why can the air conditioning connection be made of copper tube? How about rubber tube and aluminium pipe? Please heroes pointing for the dishes.

In fact, aluminum can, such as the refrigerator evaporator is aluminum, not only with the hose, the hardness is not enough in fact even the refrigerator either with brass or aluminum, for a long time or leakage, so you can not use the hose. The aluminum tube in the fridge is the easiest place to leak

Q:How long is the service life of a rubber tube?

This is really bad to determine, the environmental impact is very large, so it is difficult to judge

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

Must be added, never heard without the place, the wind turbine operation produces vibration, and galvanized sheet steel pipe is fixed at a certain place, if not, fan vibration, wind pipe vibration, the wind tube life are not long.

Q:How can the rubber tube be used properly and how to use it properly?

The hose burst caused by frequent and severe pressure impact. This situation is not generally under the static pressure caused by too much, but the number and intensity and pressure impact. Engineering machinery in operation, will be repeated in the hydraulic tubing suddenly increased or decreased, which impact on the oil pressure of frequent the damage of the oil seal, resulting in increased, loosening hose leakage and rupture foaming and pipe joint. Therefore, in operation, the valve stem can not be too hard, must be gentle.

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:Can black soft rubber pipes be used as water pipes? Why is there a pungent odor?

If you have a strong smell, it must be made of reclaimed gum, and it's inferior reclaimed gum. You smell the smell of reclaimed tar.

Q:How often do the oil - resistant rubber pipes undergo atmospheric pressure testing?

Low temperature bending test at low temperature: hose clamp on rigid torsion wheel diameter hose diameter 12 times, for 6 hours at a low temperature, twisted 180 degrees within 12s when the measured torque and the standard temperature measured torque ratio. Low temperature bending: hose clamped in the diameter of the hose within 12 times the torsion wheel, parked at low temperatures for 24 hours, in the 10s to reverse 180 degrees, check whether or not the internal and external plastic brittle fracture and damage. Test of low temperature brittleness measurement hose is the most simple specimen should be bent 90 degrees at low temperature, or a hose after freezing compressed 1/2 to see whether the embrittlement, another method is to use a certain weight of the heavy hammer falls freely, to see if the specimen embrittlement impact specimen.

Q:Petroleum gas has a corrosive effect on ordinary rubber pipes and is easy to cause air leakage. So, what kind of hose must be used?

Petroleum gas is corrosive to ordinary rubber pipes and gaskets and easy to cause air leakage. Therefore, it is necessary to use rubber pipes and gaskets with strong oil resistance
