Whether in the process of purchase or use, high quality Suction and discharge 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 in 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, Suction and discharge 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.

high pressure high quality Suction and discharge pipe There are many uses. When we choose products, understanding the basis for selecting production materials for high-pressure sandblasting hose will help us to select more suitable high-pressure sandblasting hose. The following small series will briefly introduce it to you: 1. The working environment of the product comes from the working environment of high-pressure sand blasting hose, such as outdoor environment, mechanical equipment, surface, etc. Considering these factors comprehensively, anti-aging and wear resistance shall be considered when selecting materials. 2. Function: From the performance of high-pressure hose, the main function of tubing is oil resistance, so the oil resistant material of material composition is the key. The quality must be well controlled. Among the oil pipes, there are also high-pressure oil pipe series, which is what we often call high-pressure rubber sandblasting hose. Pressure is necessary, so the steel wire reinforcement layer is used as the pressure bearing layer. This wire must be selected. 3. Economic indicators: from the economic indicators of high-pressure sand blasting hose, the economy is to spend less and produce more. The stability of the material, the rationality of the formula and the cost performance ratio of the formula must be considered. 4. Safety factors: consider the safety factors of high-pressure sand blasting hose, the requirements of normal working environment of oil pipe, and the effects of anti-static, flame retardant and normal pressure resistance. Talking about materials in this field, Suction and discharge pipe company It is necessary to select suitable materials. Some important materials involving various requirements are particularly important. 5. Manufacturing technology: from the perspective of manufacturing process of high-pressure sand blasting hose, manufacturing economy, product stability and feasibility of continuous production are mainly considered. Materials shall meet production requirements as far as possible.

Use: oilfield well control operation, metal smelting, chemical industry, etc. High temperature environment with heat source or thermal radiation. Hydraulic control pipeline of BOP for oil exploration and drilling. High pressure flame-retardant sand blasting pipe is mainly used for hydraulic transmission, medium transmission or power transmission under high-pressure, flammable and high-temperature environment. This product has been widely used in petroleum, chemical, marine, metallurgical and other industries. Flame retardant and fire-resistant: structure: take high temperature and high pressure steel wire winding hose as the base, and the outer skin is covered with nano fire-resistant coating, stainless steel wire braid and flame retardant layer. Hydraulic pipes in high-temperature environment near open fire, such as metallurgical industry, steelmaking, blast furnace, open hearth furnace, etc. Main Uses Hydraulic transmission is widely used in petroleum, chemical, marine transportation media or power transmission under high-pressure, flammable and high-temperature environments. Our products flame retardant sand blasting pipes are characterized by high pressure resistance, fire resistance, heat insulation, oil resistance, acid and alkali resistance. Suction and discharge pipe company When used in oil drilling well control system, it is superior to ordinary hard pipes, safe and reliable, easy to install and disassemble, time-saving, labor-saving, corrosion resistant, maintenance free, and long service life. Fire resistance: it can work for 15 minutes at 750 ℃. Oil resistance: Immerse in hydraulic oil at 40 ℃ - 100 ℃ for 24 hours without deterioration or falling off.

Jiangxi Suction and discharge pipe It is widely used in mining, chemical industry, construction and iron and steel fields. At present, 90% of ball mills, rod mills and moistening mills on the market still use manganese steel cylinder liners, and the manganese steel material consumed on liners alone every year is more than one million tons. The emergence of rubber liners is favored by many big customers in the ball mill field. What are the indexes that affect the rubber lining plate of the ball mill? 1. Conditions of ball mill use scenario The feeding particle size of ore also plays an important role, so a good ball mill rubber lining plate will be designed according to the size of the customer's mill, feeding particle size, and steel ball diameter. Select the rubber formula suitable for customers, and carry out mapping, design, testing and processing. 2. Rubber formula and processing technology: The rubber material and formula directly affect the performance of the rubber lining plate of the ball mill. Wear resistance is a key factor. It is impossible to determine how long its service life is because of the impact of industrial and mining conditions. The second is corrosion resistance. This is the characteristic of the formula, so even if the appearance is the same, the performance is an advantage. Do not buy for cheap. 3. Regular maintenance: everyone knows that the rubber lining plate of the ball mill is fixed to the cylinder by means of T-bolts, so it is also very important to regularly check the tightness of the bolts and the wear of the rubber strips inside the cylinder. In order to avoid damaging the rubber lining plate of the cylinder and the cylinder of the ball mill when the lifting strip is worn out, the gain is not worth the loss. Suction and discharge pipe company One of the advantages of the manganese steel lining plate is that the replacement is simple and only needs two people to operate, and it can be replaced wherever it is broken. This is an advantage that the manganese steel lining plate does not have.
