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

Look at what, the water does not move, you can use 5-10 years, activities may not! Generally 3-5 years resistant to oil!! See how it works!!

Q:What are the categories of hose?

A rubber hose products structure: hose cloth; woven hose (fiber braided hose, steel wire braided hose); winding hose (fiber winding hose, hose winding wire); knitted hose, hose and other circular weaving hose (rubber hose, rubber and plastic composite hose and hose, drilling hose, etc.).

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

The exhaust fan running noise and vibration is relatively large, the wind pipe made of sheet iron, the thin wall affected by the fan vibration will produce two times the noise, so the general air pipe to both sides of fan and soft joints, if no one in the floor or the condition of small diameter pipeline can not be added.

Q:What is the difference between plastic lined steel pipe and rubber lined steel pipe?

Lining plastic pipe plastic powder hot rotational molding, conveying chemical wastewater, circulating water treatment. The rubber lined steel pipe is made of cold sticky or vulcanized material to transport water quality, liquid and paste

Q:Is there a tolerance standard for rubber tubes in length?

Just think, in the use of the tube, is the important dimension of diameter and wall thickness of the pipe, a little a little long, short should not affect the use, especially the rubber tube, right?! so imagine, rubber tube should not have standard tolerances in length (requirements).

Q:Excuse me: how can a pen with a rubber tube attract more ink?

Pull out the iron sleeve outside the rubber tube and suck it again and again

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:How to remove hose odor?

The 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 skeleton layer is the pressure bearing layer of the rubber tube, and gives the strength and rigidity of the pipe body. The working pressure of the hose depends on the material and structure of the skeleton.

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..

Q:Classification of metal hoses

Corrugated metal hose from the structure point of view, metal bellows with two pieces of tape and pipe, they can be molded out of ring bellows and spiral bellows. Just because the corrugated pipe buckle strip forming there is always a certain length of brazing or welding and joints, these places often have accumulated working medium residue, and precipitated a mechanical impurities pollution cavity cleaning test and working medium. As a result, its trustworthiness is relatively poor. Bellows ring is the number of rings and several concave diaphragm outer concentric semi circle tangent, and several inner concave semicircular ring connected with the vest tangent to the special geometry of the pipe. Its billet is mainly made of tubes, and this kind of bellows has the characteristics of large flexibility, good elasticity, simple manufacture and small rigidity. Suitable for making general pressure, flexible requirements of high, medium diameter of the metal hose. Spiral corrugated pipe is a certain length of the spring winding shaped diaphragm spring shape around the outer edge and concave concentric semicircular ring tangent, and inner spring winding shaped concave semicircular ring connected with the vest tangent to the special geometry of the pipe. The corrugated tube has the characteristics of high strength, large rigidity and simple manufacture, and is suitable for making metal hose with high and medium pressure requirements, high and medium pressure, medium and small diameter.
