Taiyuan Sanding pipe It is composed of sand blasting hose, net sleeve and joint. The sand blasting hose is the main body of the rubber sand blasting pipe, playing a flexible role, and the net plays a role of strengthening and shielding; Joints play the role of connection. For different use requirements, they are connected in different ways: sandblasting hose, net sleeve and joint are connected by welding, which is called welding type; The connection in the form of mechanical clamping is called mechanical clamping. In addition, the combination of the above two methods is called hybrid clamping. Rubber sand blasting pipe products include oil suction hose, steam hose, sand blasting hose, acid and alkali suction hose, food hose, oxygen blowing hose and various special-shaped hoses. It is widely used in machinery, chemical industry, petroleum, metallurgy, food and other industries. What is the pressure range of pressure resistant rubber sand blasting pipe: the pressure range of hose is generally Pn 0.6-32.0 MPa. The rubber sand blasting pipe up to 42.0 MPa is the main pressure bearing part of the hose installed in the pressure pipe, and it acts as the sheath of the sand blasting hose. Sanding pipe company One or more layers of stainless steel wire or steel strip can be selected for braiding according to the pressure in the pipeline and the place of use. It can also achieve the effect of reducing noise. This is why some rubber sand blasting pipes use rubber sand blasting pipes.

Taiyuan Sanding pipe Also called rubber hose for sand blasting. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. The common application fields are shipbuilding, machining, spraying industry, etc. Appearance of abrasion resistant sand blasting rubber hose: 1. Light abrasion resistant sand blasting rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, central fabric or cord reinforcement layer, medium rubber layer and outer rubber layer; 2. Heavy abrasion resistant rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, cloth clip or cord reinforcement layer, steel wire framework reinforcement layer, medium rubber layer Composition of outer rubber layer 3. The steel wire braided wear-resistant sandblasting hose is composed of black, yellowish or transparent wear-resistant rubber inner layer, single-layer or multi-layer steel wire braided reinforcement layer, medium rubber layer and outer rubber layer. Purpose Abrasion resistant sand blasting hose is a kind of material conveying pipe, which is mainly used for conveying solids containing particles such as particles, gravel, cement, quicksand, mud, gypsum, etc. It is suitable for various tunnel projects, tunnels, caverns and other engineering operations. The general working pressure is less than 12 bar, and the higher bursting pressure can reach 36 bar. Sometimes the vacuum rich negative pressure parameter is 0.8 bar 0.9 bar. Sanding pipe company Hydraulic requirements 1. The maximum working pressure of wear-resistant sand blasting hose is 0.63MPa. 2. The hose shall be free from water seepage, local bulge, expansion and other abnormalities when conducting hydraulic test under twice the working pressure. Keep the pressure of anti-static hose for 1min, and the length change shall not exceed ± 0.8%, the outer diameter change shall not exceed ± 10%, and the torsion per meter shall not exceed 60 º. 3. The bursting pressure of the hose shall not be less than 4 times of the working pressure.

Taiyuan production In places that must be crossed or may rub with the mechanical surface when working, hose clamps or springs and other protective devices should be used to prevent the outer layer of the sandblasting hose from being damaged. Sand blasting hose shall be arranged to avoid heat source as far as possible and away from the performance of engine exhaust pipe. If necessary, sleeve or protective screen can be used to prevent the hose from being heated and deteriorated. When the sand blasting hose must be bent, the bending radius should not be too small, and should be greater than 9 times the outer diameter. There should be a straight line section greater than 2 times the outer diameter of the pipe at the joint between the rubber hose and the joint. How high-quality the products and equipment we use are, it is inevitable that there will be some large and small failures in the process of using them, which will more or less have a certain impact on our work. Just like the use of sandblasting hose, there are traces of its outer adhesive seam, problems must be solved, For this, we explained the following solutions: First, the used water cloth should be used according to the original elastic edge of the water cloth when it is reused. 2： When we wrap the water cloth around the seam of the sandblasting hose, we should apply sufficient and uniform pressure to the pipe body. 3. The water cloth with different widths should be selected according to the size of the outer diameter of the wrapped sandblasting hose (for hose with an outer diameter of less than 30mm, the width of the water cloth should not exceed 90mm). The overlapping width of the water cloth should be 3/5-2/3 of the width of the water cloth.

The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. production Sanding pipe The vibration of the unit is transmitted to the ground hall through the bridge connecting the sand blasting hose pipe, and the noise value reaches 45dB. In such an environment, people always feel uncomfortable. After the improved design, sandblasting rubber pipes were connected in series on the connecting pipes, which not only absorbed some of the noise generated by the unit vibration, but also the noise generated by the fluid pulsation in the pipeline system. At this time, the noise value in the ground hall was only 33dB, greatly improving the environment in the hall. The movable cylinder on the vulcanizing press will move upward and downward for the need of loading and unloading the mold. After repeated reciprocating movements, the copper serpentine will suffer from fatigue fracture. Although it can still be used after repair, it will cause time loss if it is stopped for repair. Sanding pipe company Although it has good soft properties and strong fatigue resistance, it is weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not continue after several months of use. The good comprehensive performance of sand blasting hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often severe conditions such as fatigue, corrosion, vibration, compression, impact, etc. Under such circumstances, it is most appropriate to use sandblasting hose to compensate for the position movement of the pipeline.

Whether in the process of purchase or use, production Sanding pipe The quality of all needs to be checked regularly. During the inspection, the following items should be noted. 1. Standard size and actual error of high-pressure rubber hose: because the inner diameter and outer diameter of high-pressure sand blasting pipe and the outer diameter of the skeleton layer will shake, if the shaking amplitude exceeds the allowable limit, the balance of the buckling amount of the sand blasting pipe joint cannot be guaranteed, and the quality of the sand blasting pipe assembly cannot be guaranteed. Therefore, for the sand blasting pipe selected for the production of sand blasting pipe assembly, it is necessary to strictly check whether the inner diameter and outer diameter of the skeleton layer meet the requirements, and the requirements for the outer diameter error can be appropriately relaxed. 2. Wall thickness error of high-pressure hose: due to the local pain of the rubber layer in the high-pressure sandblasting pipe and the influence of the overlapping width of the rubber layer of the high-pressure sandblasting pipe quality inspection center between the skeleton layers, the wall thickness error of the sandblasting pipe may be too large. If the wall thickness error exceeds the allowable range, it will affect the tightness and pull-out strength of the connector, and even cause some deflection (tilting head) of the hose assembly connector. Quality inspection of high-pressure sand blasting pipe Therefore, the wall thickness error of sand blasting pipe should be strictly controlled. Generally, the rubber hose with wall thickness error exceeding 0.5mm shall be selected stably. 3. Adhesion between each layer of high-pressure rubber hose: high-quality high-pressure sand blasting pipe shall have prominent integrity, that is, the quality inspection of high-pressure sand blasting pipe shall have high adhesion between each structural layer, and the adhesion between each adhesive layer shall become an integrity. Only in this way can we meet various technical requirements in the process of joint installation and fastening, and only in this way can we ensure the quality inspection requirements of high-pressure sand blasting pipes for sand blasting pipe assembly. Therefore, Sanding pipe company It is necessary to control the adhesive force between each layer of the rubber hose not lower than that specified in the technical standard, and the rubber hose with high adhesive force shall be selected as far as possible to produce the rubber hose assembly.
