one Liaoning Corbel tube When using, the talcum powder on the inner wall of the hose must be blown clean to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with acids, alkalis, oils and other organic solvents that can damage the hose. The storage temperature shall be - 15~40 ℃, and the distance from the heat source shall not be less than 1m. 3. According to the national standards, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; The acetylene hose is black, the working pressure vessel is 0.3MPa, the inner diameter of the hose is 8mm, and the outer diameter is 16mm. 4. The gas cutting operation requires a large oxygen output, so the valves of the gas cylinder (or oxygen pipeline) connected to the high pressure end of the oxygen meter should be fully opened to ensure adequate flow and stable pressure. The low pressure gauge has indicated the working pressure, but the pressure drops suddenly when using oxygen. At this time, it is easy to backfire and may backfire into the oxygen hose to cause explosion. 5. Oxygen hose and acetylene hose shall not be mixed or substituted with each other, and oxygen and hose shall not be used to blow away the blockage of acetylene hose. At the same time, it is necessary to check and eliminate the defects such as gas leakage and blockage of the welding torch at any time to prevent the formation of oxygen and acetylene mixture in the hose. It should be pointed out that the hose color specified in the national standard is opposite to that specified in the international standard (ISO) (oxygen hose is black, acetylene hose is red). At the same time, it is different from the original ministerial standard (HG4-605-66) that oxygen hose is red and acetylene hose is green. Before 1966, domestic oxygen hose was black or green and acetylene hose was red. thus Corbel tube Where can I find it? It causes inconsistency between the understanding and habits of the supply department and the user, and is easy to cause accidents due to the mixing and substitution of rubber hoses. At present, it should be emphasized that unified understanding and use should be carried out in accordance with the provisions of national standards, and attention should be paid to distinguishing the rubber hoses of imported equipment.
Liaoning high quality 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.
high pressure high quality Corbel tube 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, Corbel tube Where can I find it? 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.
I, high quality Corbel tube Quantitative display of quality. In the evaluation plan prepared by the Ministry of Health and Social Insurance for the medical and health system, some indicators were put forward for the service quality of the hospital, such as the number of deaths before and after the operation, the number of unplanned rehospitalization, the infection rate of patients in the hospital, and the immunization rate. It can be seen that the quantification of quality is to reflect the quality of things through a series of quantitative analysis and synthesis. Sand blasting hose enterprises use public opinion polls to measure benefits and service quality. Since the purpose of administrative activities is to meet the needs of society or the public, the best way to measure the social effect and quality is to face the service objects, understand their evaluation and their satisfaction. Although popular, public opinion polls also have limitations, such as high cost, which is difficult to be accurate and reliable due to the influence of public judgment. In addition, the satisfaction of beneficiaries does not answer the question - is this service provided to those who need it most? III, Corbel tube Where can I find it? Administrative departments and public service institutions with single business nature. For those departments that have applied the quality assurance system, their performance evaluation only pays attention to efficiency and economy.
