DIN EN 857 2SC Standard
Tube : Oil resistant synthetic rubber
Reinforceent : two high tensile steel wire layers 2 w
Cover : Abrasion and weather resistant synthetic rubber
Temperature range : -40 ℃ to +100 ℃。

Q: What is the difference between the precast beam of the bridge and the method of pulling out the rubber tube after pouring the concrete? What's the difference between design and calculation?: Construction process, in order to avoid concrete into bellows, influence later wear steel strand, construction units generally use PVC and other rubber tube into bellows, in order to double insurance, don't let concrete into. Its length is certainly larger than the length of bellows (750mm at one end for easy operation)

Q: What do you mean by "DN" on hydraulic hose?: Hydraulic hose temperature: -40 ~ 120 DEG C, product specification range: DN2.5mm ~ DN305mm.

Q: The function of rubber joint?: The seamless seamless rubber joint produced by the rubber joint prevents the corrosive medium from eroding the inner wall of the rubber joint and improves the service life in the high temperature resistant, acid resistant and oil resistant pipes

Q: Water heater hose 4 points and 6 points difference: 4, in charge of 1/2 inches of pipe, 6 in charge of 3/4 inches of pipe, different specifications of some differences.The so-called 5 turn 4, should be different diameter, that is, pipe and pipe joints, parts of different specifications.A bellows is a pipe, not flat, corrugated.

Q: Difference between non-standard rubber joint and national standard rubber joint: Rubber joint national Ministry of water conservancy is standard CJ/T208-2005 documents of rubber joint standard, this paper has clear rules for the product, identify the products should meet the following characteristics: standard rubber joint extrusion is produced by the rotation of the screw, the glue is advancing, and with the help of the mouth, but the needs of various semi-finished extrusion the shape of the. The extrusion process is characterized by uniform and compact quality and easy conversion of semi-finished product specifications and section shapes. The extrusion process of the national standard rubber joint in the extruder is divided into two parts: one is the extrusion system used for pushing the rubber; the two is the die system, which is used to form the rubber to make a definite section shape. Therefore, in the process of pressing, the rubber layer is usually more than ten layers, and the rubber joint has the characteristics of compact structure and high pressure resistance.Non-standard rubber joint is in the national standard between substandard products and national standard products, often illegal businesses use to reduce the rubber joint, the number of layers to reduce the cost of rubber joints. Use non-standard products instead of GB products. Non-standard products in use process, because the arc bearing layer, rubber layer is insufficient, the strength drops, in the use process is easy because the pressure withstanding insufficient causes the pipe network to burst.

Q: What are the matters that should be paid attention to when installing rubber hose joint in water pump?: Installation notes:?1, Shanghai rubber pipe joint non super displacement limit at the time of installation;?, 2 installation bolts to be symmetric, gradually tightening pressure, to prevent local leakage;?3, flat, suspended, vertical installation of rubber pipe joint, actual axial displacement pressure rubber tube joints should be smaller than the pipe support, otherwise should install anti pull off device to prevent work pressure;?4, rubber pipe joints should be away from heat, ozone, no strong radiation light. Exposure and use of media that do not meet the requirements of the product;?5, rubber pipe joint in the transportation, loading and unloading, installation, no sharp instruments across the surface of the sealing surface;

Q: What is negative pressure rubber shock proof joint? Is vacuum piping available?: With high pressure, good elasticity, large displacement, balance pipe deviation, absorbing vibration and noise reduction effect, convenient installation, but also can greatly reduce the noise and vibration of the pipeline system, which can solve all kinds of line interface displacement fundamentally, axial expansion and concentricity problems, mainly installed in the pump inlet the vacuum pump inlet, or large, can solve the 100% rubber joint suction flat phenomenon.

Q: The gas water heater uses metal pipes and rubber pipes: Rubber tube will be aging for long time, it is better to use gas special stainless steel bellows

Q: What is the high and low pressure circuit of diesel engine?: High pressure oil from the pump to the diesel engine combustion chamber nozzle before that, due to the movement of the piston engine in the process of pressurized environment into the combustion chamber of diesel oil injection so the pressure is high, the combustion chamber is higher than the minimum compression pressure environment stroke made, otherwise the oil can not be sprayed into the combustion chamber. So this section of the road is made of metal.
