Q:Difference between non-standard rubber joint and national standard rubber joint

Non standard is in shape and about the structure of standard atlas case material of flange thickness, flange ring thickness, diameter and thickness that relax the requirements, strictly speaking, these are unqualified products, of course, a certain extent to relax the standard does not affect the use, but too much to the influence of the relaxation of standards to use performance.

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

Measures to prevent aging: from the point of view of aging, one of the main reasons is the polymer structure itself. Therefore, it is important to improve the structure of polymers to improve their aging ability. For example, in rubber vulcanization, there are still unsaturated double bonds, and rubber products in use and it is difficult to avoid the erosion of sunlight, oxygen, ozone, so people on the synthesis of new varieties, to avoid or reduce the polymer chain of rubber double bonds, such as ethylene and propylene two monomer by copolymerization made two yuan B two rubber, different from other synthetic rubber is one of the major characteristics in the structure of the backbone is not completely saturated with double bond, making it the most ozone resistance, chemical resistance, high temperature resistant rubber aging; there is a kind of antioxidant, such as adding oxygen or ozone to prevent aging caused by antioxidants. Add UV stabilizers, heat stabilizers, preservatives and other unfavorable factors, and caused by aging.

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 are the properties of stainless steel metal hose materials?

The stainless steel metal hose is made up of corrugated pipe, stainless steel braid net and two ends joint.

Q:Will the outside of the brake hose of the car burst apart?

If the brake oil pipe (you should be the brake hose) is best, I'd recommend replacing him

Q:What are the types of cable metal hose connections?

Mainly used for internal thread connection pipe and the hose thread cable.

Q:Hydraulic hose joint configuration

Gas safety hose joint: a joint security guarantee gas transmission, including metal hose, Baotou, connecting pipe and a connecting nut, one end of the connecting pipe and hose, metal hoop pressure Baotou into one, the other end is connected with the inner hole of flange nut for different aperture of two parts, large hole diameter is slightly larger than the connection the flange is provided with internal thread, big hole depth is larger than the thickness of flange, hole diameter is slightly larger than the connecting pipe outer diameter and smaller than the outside diameter of the flange.

Q:The basement of submersible sewage pump outlet pipe installation need and flexible rubber joint is not installed? Can not?

Rubber joint, also called shock proof throat, is mainly used in the entrance and exit of pumps. It is used to absorb the noise caused by vibration during the operation of pumps.

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.
