Whether in the process of purchase or use, high quality Sanding 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 of 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, Sanding 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.

polyurethane high quality Sanding pipe Maintenance measures; Cleaning: It is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber tube must be inspected to ensure that there is no structural damage. Pressure: If the rubber pipe is under great pressure during use, or the outer layer of the rubber pipe will contact with the conveyed liquid for a long time, it is recommended to conduct a hydrostatic test. Due to the natural characteristics of rubber, the physical properties and performance levels of all rubber products will change. This change usually occurs over time, depending on the type of rubber used. However, changes may also accelerate due to several factors or a combination of several factors. Other materials used to reinforce rubber tubing may also be adversely affected by improper storage conditions. Detailed step 1. Polyurethane sand blasting pipe mandrel: the mandrel is usually pulled backward, mainly to increase the firmness of the connection between the mandrel and the hose. After the spindle barb processing is completed, the barb tip must also be passivated, otherwise the barb tip will pierce the lining material of the high-pressure rubber tube during the buckling process. Sanding pipe company Even if the high-pressure rubber pipe joint is firmly buckled, if the inner layer is damaged, high-pressure water will leak from the buckle. 2. Polyurethane sand blasting pipe sheath: the sheath is generally in the form shown in the figure, the wall thickness should be moderate, and the internal rectangular tooth height should not exceed 2mm, that is, (d-d) should not exceed 4mm.

If conditions permit, secondary vulcanization shall be adopted, high quality Sanding pipe Effectively remove the odor generated during the consumption of odorless hose. Pay attention to the volatilization of various ingredients in the odorless hose formula. When the odorless hose is consumed, in addition to paying special attention to the raw materials and vulcanization process of the reclaimed rubber, pay attention to the selection of various ingredients and whether they will volatilize in the vulcanization process. The volatilization of vulcanizing agent, accelerator and antioxidant will produce a great smell. It is very important to accurately determine the length of the required rubber sand blasting pipe by using the rubber sand blasting pipe. It shall also be checked whether the use conditions of the rubber sand blasting pipe meet the requirements of the selected rubber sand blasting pipe. It should be ensured that the rubber sand blasting pipe you will use is the most suitable one. The working pressure and suction should be carefully determined. Special attention shall be paid to the test standard pressure change or pressure peak of wear-resistant sand blasting pipe. Exceeding the promised maximum value will greatly shorten the service life of the rubber sand blasting pipe. Both ends of the rubber sand blasting pipe cannot be continuously immersed in the transported material. If the bending radius of the rubber sand blasting pipe is less than the minimum value, Shijiazhuang Sanding pipe Its service life will be greatly shortened. Therefore, before installation, it is recommended that you consult the application of information, especially the information about the bending radius of the rubber sand blasting pipe. Protection and cleaning of rubber sand blasting hose: it is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber sand blasting pipe must be inspected to ensure that it does not show structural damage.

high quality Sanding 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. Sanding 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.
