production Peristaltic pump pipe Acid and alkali resistance: there is no obvious change after soaking in 44 solutions for 24 hours; Pressure resistance: under the pressure of 52.5 MPa, the pressure is stable for 5 minutes without leakage, the surface of the pipe body is not deformed, and the damage pressure is greater than 105 MPa; Heat preservation: place the pipe in an environment of 300-50 ℃, with clear water in the pipe for 20 minutes, and the temperature ratio inside and outside the pipe is 1:40. The wear-resistant sand blasting hose is a material conveying pipe. The wear-resistant sand blasting hose is a material conveying pipe. Common black, yellowish or transparent; Most of them are wrapped by external rubber packing belt, and the steel wire is usually set between the internal and external rubber for negative pressure operation. The utility model is mainly used for conveying liquid containing solid particles such as particles, gravel, cement, quicksand, concrete, gypsum, etc., and is suitable for various tunnel projects, shafts, tunnels, and other engineering operations. The inner rubber and outer rubber of sand blasting pipe made of ordinary materials are usually made of wear-resistant materials, most of which are nitrile rubber (acrylonitrile butadiene copolymer), styrene butadiene rubber (oil extended styrene butadiene rubber), etc., Or PARA rubber (trefoil rubber), the inlet hose has better performance. According to the working conditions and the degree of loss of material particles to the transmission medium, the sand blasting pipe is generally divided into light sand blasting pipe and heavy sand blasting pipe. Spiral wire will make them suitable for negative pressure environment. Light sandblasting pipe Light sandblasting pipe Light sandblasting pipe is usually used in marine sandblasting and quicksand operations. The ordinary inner rubber is made of wear-resistant nitrile rubber (NBR), while the outer rubber is wrapped with composite rubber. Heavy sandblasting pipe Heavy sandblasting pipe Heavy sandblasting pipe is used for sandblasting sand, pebble, mud, etc. Equipment. Peristaltic pump pipe company Sand blasting vacuum tube Sand blasting vacuum tube The sand blasting vacuum tube is embedded with spiral steel wire, and the general vacuum negative pressure can reach 0.9 bar. Common parameter definitions The wear-resistant sandblasting pipe generally has the following parameters: folding pressure is generally within 12 bar, higher sandblasting pressure can reach 36 bar, and sometimes vacuum negative pressure parameters such as 0.8 bar~0.9 bar are required.

Daqing Peristaltic pump pipe Structure type of product: sand blasting hose is mainly composed of liquid resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer and outer rubber layer. The inner rubber layer has the function of bearing the pressure of the transmission medium and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (0.3-2.0 steel wire) layer is the reinforced skeleton material. Application of sandblasting hose products: high-pressure sandblasting hose is mainly used for mining hydraulic support and oil field exploitation, and is suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanical and automatic hydraulic systems in various industrial sectors to transport petroleum base with a certain pressure (higher pressure) and temperature. (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquid (such as emulsion, oil-water emulsion, water). And liquid transmission. The working withstand voltage can reach 70-100 MPa. The company's sand blasting hose standards refer to national standards/T10544-03, DIN 20023, and SaE100 R9-13. Peristaltic pump pipe company Made of special synthetic rubber, it has excellent oil resistance, heat resistance and aging resistance. The rubber hose has high bearing pressure and superior pulse performance. The tube body is tightly combined, soft to use, and has little compression deformation. The hose has excellent bending resistance and fatigue resistance. The sandblasting hose is 20m long and can be made within 50m as required.

production Peristaltic pump pipe The inner rubber layer of（ ф 0.3-2.0 reinforcement layer) is the skeleton material that plays the role of reinforcement. What should be paid attention to when storing the wear-resistant sandblasting pipe. 1. The wear-resistant sandblasting pipe should be stored as loose as possible. Generally, rubber hoses with inner diameter less than 76 mm can be wound and stored. 2. During the storage of wear-resistant sand blasting pipe, it is strictly prohibited to stack heavy objects on the pipe body to prevent external extrusion and damage. 3. During the storage of wear-resistant sand blasting pipe, do not contact with acid, alkali, oil, organic solvent or other corrosive liquids and gases, and the heat release should start from 1m away. 4. The storage period of wear-resistant sand blasting pipe shall not exceed 2 years, and it shall be used by the first person to prevent the quality of rubber pipe from being affected by long-term storage. 5. When wear-resistant sand blasting pipes need to be temporarily stored in the open air, the site should be flat and the rubber pipe should be laid flat. The upper cover should be placed under the rubber pipe and no heavy objects should be stacked. At the same time, the hose shall not contact the heat source. 6. The storage place of the upper and lower rubber pipes in the well shall be kept clean and ventilated, and the relative humidity shall be 80. The temperature of the storage place shall be kept between - 15 ℃ and 40 ℃, and the rubber pipe shall be protected from direct sunlight and water spray. 7. When storing wear-resistant sand blasting pipe, Peristaltic pump pipe company Both ends of the hose shall be sealed firmly to prevent sundries from entering the hose. 8. When the wear-resistant sand blasting pipe is stored, it should be placed separately according to different varieties and specifications, not mixed, and hang the management board. 9. In order to prevent the pipes from being pressed and deformed during storage, they should not be stacked too high, and the stacking height should not exceed 1.5m. It also requires rubber hoses to be "stacked" frequently during storage, at least once a quarter.

Daqing Peristaltic pump 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.

I, production Peristaltic pump pipe 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, Peristaltic pump pipe company 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.
