1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Flange rubber pipe Price Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Hangzhou Flange rubber pipe The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.

Although fire Hangzhou Flange rubber pipe Explosion proof pipe) can be compressed and stretched, but if the installation position is incorrect, it will break quickly and reduce the service life. The sandblasting hose can be installed horizontally, vertically or obliquely. The most ideal condition is vertical installation. At the same time, avoid installing near the wheel, and install baffle if necessary. Generally speaking, the flame spraying metal sand blasting hose (explosion-proof pipe) can be divided into three lengths: the first is the compression length, that is, the length of the sand blasting hose when it is compressed to the limit position; The second is the installation length, that is, the length of the sandblasting hose when it is in the middle of half of the maximum displacement. The third type is the stretching length, that is, the length when the sandblasting hose is stretched to the maximum limit. When installing the sandblasting hose, the sandblasting hose should be in the middle position, which is called the installation length. When installed at this position, the sandblasting hose can move in two directions when bearing axial load. Otherwise, if it can only move in one direction, its strength will be affected and its service life will be reduced. In the actual installation process, considering that measuring the length of the sandblasting hose with a ruler according to the calculation results may affect the production efficiency, some foreign manufacturers directly install the ruler on the sandblasting hose, and cut the ruler after installation. From the structural point of view, the metal flame spraying metal sandblasting hose (explosion-proof pipe) is composed of strip and tube parts, which can form annular flame spraying metal sandblasting hose bellows and spiral flame spraying metal sandblasting hose bellows. Flange rubber pipe Price Just because the corrugated pipe of the fire sprinkler metal sandblasting hose formed by this article always has a certain length of brazing or welding buckles and fire sprinkler metal sandblasting hose joints, the residues of the working medium often accumulate in these places, and the cleaning test and mechanical impurities in the working medium will deposit down to pollute the inner cavity. Therefore, its use reliability is relatively poor.

production Flange rubber pipe Or PVC steel wire spiral reinforced pipe. The commodity is made of high-quality PVC plastic raw materials. PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework. The inner and outer tube walls are clear, lubricated, free of bubbles, and the fluid transportation is clearly visible. Silicone fiber tube is resistant to low concentration of acid and alkali, high elasticity, not easy to age, and has a long service life. Resistant to high pressure and can be kept intact under high pressure and vacuum. PVC steel wire pipe is made of new PVC reinforced materials, and has made great progress in compressive strength and hardness. The main production method of silica gel steel wire pipe is multiple production method. The main types of steel wire pipe in shopping malls include high pressure steel wire pipe, low pressure steel wire pipe, steel wire skeleton pipe and Tongming steel wire pipe. The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Flange rubber pipe Price After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.

Due to the limitation of spatial location conditions, production Flange rubber pipe The installation stress of can often bring various difficulties to the installation work: formed pipes cannot be installed; When you bend down, you are about to come. If you make do with pipes, local cold correction will inevitably occur. According to the size of the pipeline and the specific situation on site, the cold correction amount varies from several millimeters to tens of millimeters, some as high as hundreds of millimeters. Practice has proved that the greater the quantity, the higher the internal stress. These residual installation stresses in the rubber sand blasting pipe are undoubtedly huge hidden information. The lubricating oil duct of a certain type of engine bearing was broken for many times due to excessive installation stress in actual operation. Because it can be bent at will, the internal stress generated by bending under the condition of rated bending radius is very small, which brings great convenience to the installation work, and also plays a certain role in ensuring the safe operation of the rubber sand blasting pipe. This is the main reason why some rubber sand blasting pipes must be used. Since it is necessary to load and unload the mold, the movable cylinder on the vulcanizer will move up and down. After repeated reciprocation, the copper serpentine tube will undergo fatigue fracture. Although it can continue to be used after repair, stopping for repair will cause time loss. Hangzhou Flange rubber pipe Although it has good flexibility and strong fatigue resistance, it is also weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not be used after several months. The good comprehensive performance of rubber sand blasting pipe is fully reflected here.

Prof. Weina, University of New South Wales, Australia? Sahajwara has developed a new method of using waste rubber and plastic for steel production - polymer injection process. Hangzhou Flange rubber pipe It can not only greatly reduce the environmental pollution caused by waste rubber and waste plastics, but also effectively reduce the cost of steel production. Waste rubber and plastic contain a lot of carbon. Waste rubber and plastic are put into the electric arc furnace as substitutes for carbon element. The carbon originally locked in the waste plastic hose will react at ultra-high temperature and burn with coal to become clean fuel, thus reducing greenhouse gas emissions, At the same time, it also alleviates the environmental pollution caused by using them as landfill. The advantage of polymer injection process is that by injecting polymer and coke or anthracite rubber tube mixture, the volume of slag can be increased and the foaming degree can be increased, which can extend the arc length, increase the heat transfer from the arc to steel, reduce the heat loss through the slag and side walls, and thus improve the power efficiency. This reduces power consumption by about 3%. For every 1 ton of steel, about 24% of the cost comes from the cost of electricity. After polymer injection technology is adopted, each furnace of steel is, Flange rubber pipe Price The average total amount of carbon injected can be reduced by 10%~20%. In addition, the potential price of polymer is lower than that of coke, and the total cost of carbon injection can be saved by 15%~35%.
