production Sandblasting hose 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. Sandblasting hose 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.
Wuxi Sandblasting hose It is used in transportation, construction and other industries. Correct procurement can not only save procurement costs, but also ensure its operation safety. The following series will introduce some purchase suggestions, hoping to help you. Suggestion 1. Determine the type of hose brand to be purchased according to the connection equipment and budget of sandblasting hose, such as high-tech equipment. Naturally, it is necessary to buy large brand sandblasting hose. However, if it is industrial and mining equipment with extremely fast scrapping speed, general quality is enough. Recommendation 2. The price of sand blasting hose with uniform quality grade is also different, especially for large-scale procurement, the price difference will be obvious, so it is necessary to have three quality grades to determine the final partner. Suggestion 3: Select appropriate channels. Sand blasting hoses are usually purchased in large quantities, which means that their turnover is relatively large. Therefore, reliable channels need to be selected to ensure the safety of their own loans. Sandblasting hose company The purchase of sand blasting hose components is also described in the model. High pressure hose assembly, pipe body specification (inner diameter, number of pressure layers, winding or braiding), joint type (national standard or Eaton), protective layer type, length and other parameters are the basic data for determining hose assembly.
production Sandblasting hose It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Sandblasting hose company During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.
Wuxi Sandblasting 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.

Sandblasting hose company 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.
Prof. Weina, University of New South Wales, Australia? Sahajwara has developed a new method of using waste rubber and plastic for steel production - polymer injection process. Wuxi Sandblasting hose It can not only greatly reduce the environmental pollution caused by waste rubber and waste plastics, but also effectively reduce the cost of steel production. Waste rubber and plastic contain a lot of carbon. Waste rubber and plastic are put into the electric arc furnace as substitutes for carbon element. The carbon originally locked in the waste plastic hose will react at ultra-high temperature and burn with coal to become clean fuel, thus reducing greenhouse gas emissions, At the same time, it also alleviates the environmental pollution caused by using them as landfill. The advantage of polymer injection process is that by injecting polymer and coke or anthracite rubber tube mixture, the volume of slag can be increased and the foaming degree can be increased, which can extend the arc length, increase the heat transfer from the arc to steel, reduce the heat loss through the slag and side walls, and thus improve the power efficiency. This reduces power consumption by about 3%. For every 1 ton of steel, about 24% of the cost comes from the cost of electricity. After polymer injection technology is adopted, each furnace of steel is, Sandblasting hose company The average total amount of carbon injected can be reduced by 10%~20%. In addition, the potential price of polymer is lower than that of coke, and the total cost of carbon injection can be saved by 15%~35%.
