As production Air compression hose As an important part of sand blasting machinery, its safety plays a vital role in the safety of equipment operation. The following will briefly analyze the precautions in the use of high-pressure sandblasting pipe: I. Pipe inner diameter: inner diameter of high-pressure sandblasting pipe. 2、 Attention shall be paid to the following items in the use and design of high-pressure sandblasting pipe: 1. The bending radius of high-pressure sandblasting pipe shall not be too small, and generally shall not be less than the value specified in the assembly technology of high-pressure sandblasting pipe. The joint between the high-pressure sandblasting pipe assembly and the pipe joint shall have a straight section, and its length shall not be less than twice the outer diameter of the pipe. 2. The length of high-pressure rubber hose assembly shall consider that the high-pressure rubber hose will shrink and deform after introducing pressure oil. Generally speaking, the shrinkage rate is 3~4 times of the pipe length. When installing the high-pressure rubber hose assembly, it is not allowed to bear tension. 3. During installation, the high-pressure sandblasting pipe assembly shall be free from torsional deformation. Air compression hose Price The connecting shaft of shall be placed in the moving plane as far as possible to avoid damaging the high-pressure sandblasting pipe when both ends move with each other. 4. High pressure resistant sand blasting pipe shall avoid contact and friction with mechanical sharp corners to avoid damaging the pipe. Safety measures: to ensure the safe and reliable use of high-pressure sandblasting pipe assembly.

Yantai Air compression hose 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, 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; 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 substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first 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. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Air compression hose Price When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.

Yantai Air compression hose There are many specifications. Different installation positions require different specifications of cloth clamping sand blasting pipe, and the specification selection of cloth clamping sand blasting pipe has different requirements. The following small series will briefly introduce them to you: 1. Temperature: The selection should be based on the ambient temperature when the cloth clip sandblasting pipe is working. In case of high temperature, the temperature correction pressure shall be determined according to the working pressure and temperature correction coefficient of the cloth sanding pipe under high temperature to determine the correct pressure level. 2. Pressure: when selecting the cloth clip sandblasting pipe, check the nominal diameter and pressure gauge of the corrugated cloth clip sandblasting pipe according to the actual working pressure of the hose to determine whether to use the stainless steel mesh sleeve type. 3. Size: select the joint type, size of cloth sanding pipe and hose length according to the size of cloth sanding pipe. 4. Medium: determine the material of each part of the hose according to the chemical properties of the material medium transported in the cloth sanding pipe and the corrosion resistance of the hose material. 5. Status: According to the use status of the hose, refer to the correct use and installation method of the cloth clip sandblasting pipe and the length of the hose in the settlement compensation. Therefore, Air compression hose Price According to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe is, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe is selected.

Yantai Air compression hose The structure is composed of liquid resistant synthetic rubber inner rubber layer, medium rubber layer, I or II or III steel wire braid reinforcement layer, and weather resistant synthetic rubber outer rubber layer. Sand pumping hose features: 1. Sand pumping hose is made of special synthetic rubber, which has excellent oil resistance, heat resistance and aging resistance. 2. The rubber hose has high bearing pressure and excellent pulse performance. 3. The pipe body is tightly combined, soft to use, and has little deformation under pressure. 4. Sand pumping hose has excellent bending resistance and fatigue resistance. 5. The sand pumping hose is long, φ 20 meters above 32, φ Below 25 meters, it can reach 10 meters or even 100 meters. Sand pumping hose parameters: 1. The inner wall of nylon cord hose is smooth with little friction. Reinforcing layer: high-strength synthetic wire, spiral winding of steel wire and iron wire (sand suction pipe) 2 production Air compression hose Flange connection (ANSI150 standard flange) 3. Nominal pressure: 20BAR4, temperature: - 50 ℃ -+95 ℃ 5. Working pressure of sand suction hose and mud discharge pipe: positive pressure: 10kg; Test pressure: working negative pressure of 15kg steel ring sand suction hose: ≥ 15kg sand suction hose has strong flexibility, which is mainly used as the sand pump sand discharge pipe to connect the sand transport pipe and sand pump, as well as the pipe connection bend.

I, production Air compression hose 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, Air compression hose Price 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.
