Q:In long-term high temperature environment, silica gel tube and three yuan ethylene propylene rubber hose which is good durability?

Others, such as three yuan ethylene propylene and nitrile rubber hose, are basically black. Long term use of plastics can cause fading and deformation. The chemical properties of silica gel are stable and the physiological inertia is good. They are very resistant to biological aging, have no rejection reaction with limbs, and have better anticoagulant properties.

Q:What are the categories of hose?

According to the compression status: pressure hose; suction hose; pressure suction hose (drain suction hose)

Q:How to determine the parker381 hose joint?

Parker 381 series hose comes with Parker 43 series hose connector. Because the type, material, and surface treatment of hose joints are indistinguishable from the naked eye, these factors directly affect the quality of the hose assembly:1., if the factory internal judgments, according to Parker provided geometric parameters to determine;2., if purchased on the market, it is best to choose Parker authorized dealer (Parker authorized dealer has Parker's power of attorney);

Q:High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,

Q:What is the essential difference between rubber expansion joint and rubber joint?

A rubber joint is a hollow rubber product used for flexible connections between metal pipes. The flexible joint is also called soft rubber pipe joints, rubber joints, soft rubber joints, flexible joints, high-pressure rubber joints, rubber shock absorber etc.. It is divided into 3 kinds: flange type, fixed flange type and thread type by connection. The structure can be divided into single sphere, double sphere and curved sphere. A tubular rubber component is composed of inner and outer layers of rubber, cord and steel ring, which is vulcanized and molded and then combined with a metal flange or a parallel joint. This product can reduce vibration and noise, and can be compensated by thermal expansion and cold contraction due to temperature changes. It is widely used in various piping systems.

Q:Is flexible rubber joint and telescopic device a kind of thing?

The main features of metal pipe telescopic device are telescopic, large compensation and high temperatureUnder great pressure.And flexible rubber joint is a product!

Q:Is the installation of submersible pumps mandatory for the installation of flexible rubber joints?

According to the design requirements, choose whether the installation of rubber joints, Kannami Masashige water supply equipment Co., Ltd. is specializing in the production of rubber joint manufacturers, products and technical advice

Q:Flexible rubber joints. What do they mean by flexing?

Stainless steel bellows are not a kind of rubber joint.Flexure generally means that it can be bent repeatedly.The rubber joint mainly plays the axial and angular compensation displacement, and withstands the mechanical vibration, protects the pipeline not to burst.Stainless steel bellows can also be flexible, but the performance of vibration proof is better than that of rubber joints. If the requirements of the engineering drawings are rubber joints, it is better to be careful. Don't change it indiscriminately. Otherwise, the service life will be affected
