Q:How to detect the reliability of rubber hose

Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.

Q:The selection of valves and fittings has the following requirements

The joint of the valve is threaded with an internal thread, so that the connection in the installation is easier to select transition joints.

Q:What is the method of making large diameter rubber joint?

Rubber joint also known as shock absorber, shock absorber throat, the main function is to shock absorption, noise reduction, protection of the pipeline, compensation pipeline expansion, cold caused by displacement.Its structure: both ends are two carbon steel flanges, the middle is rubber shock absorption part.

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

K type joint has the distinction between national standard and German standard. In general, 32 and 38 tubes are used more often. The joints used on 32 of the tubes are KJR32 and KJR31.5D. 38. The joints used on the tubes are KJR38 and KJR B40

Q:Flex rubber joint installation skills, what are the materials of rubber soft joint?

Flexible rubber joint is normal for medium temperature of 0-60 DEG C usually water medium such as oil, acid, high temperature and other corrosive and texture should be selected under the peace situation should be relatively Tenai data can not be blindly on rubber joint or universal.

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

Rubber joint is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. The product uses rubber elasticity, high air tightness, medium resistance, weather resistance and radiation resistance etc., using polyester cord fabric skew high strength, strong stability and the hot and cold composite, after high pressure, mold temperature and curing. As the rubber joint has good comprehensive performance, it mainly acts as shock absorption, noise elimination and noise reduction. Therefore, it is widely used in chemical, construction, water supply, drainage, petroleum, light and heavy industries, freezing, sanitation, plumbing, fire fighting, power and other infrastructure projects.

Q:What's the difference between a silicone tube and a rubber tube?

Silicon hose performance: cold resistant, high temperature resistant. Harmless, non-toxic, tasteless;Suitable for small household appliances (coffee pot, kettle, electric iron, electric cooker, frying pan, disinfection cabinet, drinking machine, pulp machine, bread machine, gas cooker, water heater) and electronic, automobile, medical and other mechanical products.

Q:How can you pump out the water from a fishpond with a rubber tube?

If there is no pump, siphon principle can only be used.

Q:How should we distinguish between the silicone hose and the rubber tube?

Smell, silicone no flavor, rubber flavor, silicone general flexibility better, rubber mechanical better

Q:What advantages does the Parker hose have in comparison with other hydraulic hoses?

First: from the price point of view. The price of PAKER is the most expensive in the whole industry. High popularity.Second: if in terms of quality. With his quality, Ma has worked hard. Eaton. Love hair. The quality is all rightThird: from the point of view of use, the difference is not obvious. PAKER things match well
