Q:What are the properties of an oil resistant rubber hose?

The performance of the extended product is accompanied by a rubber hose in life in many areas already occupy a crucial position, which makes the hose detection is important, especially for the rubber pipe detecting water, oil and gas and other purposes.

Q:What's the metal hose for fire fighting?

Fire hose is an important component of modern industrial equipment connecting pipelines. The metal hose is used as wire, cable, automatic instrument signal wire, cable protection tube and civil shower hose, specifications from 3mm to 150mm. Small caliber metal hose (inner diameter 3mm-25mm) is mainly used for precise optical ruler sensing line protection and industrial sensor line protection.

Q:What's the cause of a default like a general rubber product?

Rubber aging is a common problem of rubber products, and aging is mainly due to internal structure or component is easy to aging due to weakness, such as unsaturated double bond, branched, carbonyl, hydroxyl and so on; at the end, the main external or environmental factors are sunlight, oxygen, ozone, heat, water and mechanical stress force, high energy radiation, electricity, industrial gas, water, salt fog, fungi, bacteria, insects etc..

Q:Installation of rubber flexible joint

The installation bolts shall be symmetrical and tightened gradually to prevent partial leakage.

Q:Do I need a shim for the flat metal hose joint?

If the two connections are flat, they must be placed gaskets, usually with PTFE gasket.

Q:Aging of natural gas pipeline

1, when in use, should always pay attention to the color of the fire. Orange flames indicate incomplete combustion of gas, and in this case carbon monoxide is released. The fire can be adjusted by adjusting the air door at the bottom of the stove, and the flame is blue.2, soup or water, containers should not be overfilled, nor unattended, so as to avoid the fire was spilled soup, water and water leakage.3, in a stew or soup, some people love the flame was very small, this can easily lead to leakage or incomplete combustion. Therefore, in the use of gas stoves, the fire can not be too small.Between the 4, and gas appliance hose inlet connector to connect closely, preferably with a pipe clip.5, in the same room, strictly prohibit the simultaneous use of two kinds of fire sources.6, the family is best equipped with dry powder fire extinguishers, so as to be prepared.

Q:What kind of rubber hose does not leak the smell of liquefied gas?

The advantages of using stainless steel corrugated hose are first strength, long life and durability, and the cracks in the rubber tube and the bite of the rat in the past are obviously not appearing on the stainless steel bellows.

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.

Q:What about leakage of hose joint?

First, the water source is cut off, then the male and female nuts which are connected with the compression joint are removed, and a plurality of threads are screwed on the thread to seal the rubberized fabric, and then the connector is re assembled.

Q:The copper joint is leaking, and the tap water hose and copper joint are leaking

1, the expansion of aluminum pipe is not expanded, and re - do the side.2, copper joints are non-standard products, replaced by standard parts.
