high quality Sand suction hose Or PVC steel wire spiral reinforced pipe. The commodity is made of high-quality PVC plastic raw materials. PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework. The inner and outer tube walls are clear, lubricated, free of bubbles, and the fluid transportation is clearly visible. Silicone fiber tube is resistant to low concentration of acid and alkali, high elasticity, not easy to age, and has a long service life. Resistant to high pressure and can be kept intact under high pressure and vacuum. PVC steel wire pipe is made of new PVC reinforced materials, and has made great progress in compressive strength and hardness. The main production method of silica gel steel wire pipe is multiple production method. The main types of steel wire pipe in shopping malls include high pressure steel wire pipe, low pressure steel wire pipe, steel wire skeleton pipe and Tongming steel wire pipe. The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Sand suction hose company After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.

Lanzhou Sand suction hose With the continuous updating of technology, the products are also developing in the continuous updating. At present, the inspection requirements of rubber hose are also improved compared with the previous ones. The inspection index of ultra-high pressure hose shall meet the following index requirements according to the requirements of the Safety Code for High Pressure Water Jet Cleaning Operation: 1) The bursting pressure shall be more than 2.5 times of the working pressure. 2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage. 3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar. Since high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents. Sand suction hose company The development of rubber hose can not be separated from cooperation, R&D and innovation can not be separated from communication, and the inspection requirements of rubber hose have been improved compared with the previous ones. The storage site shall be free of ozone, heat source and equipment generating electromagnetic field. The coiled hoses or hose assemblies shall be stored horizontally, and the stacking height shall be limited to the extent that the products at the bottom will not produce permanent deformation.

Common for ventilation duct high quality Sand suction hose What should be paid attention to during processing: the galvanized air duct shall not be connected with s-shaped, c-shaped right angle and vertical angle plugs. Clasp type air duct shall not be used for Grade 1 to 5 clean air. The rivet spacing of air duct shall be less than 100 mm. When the air purification level is 1-5, the rivet spacing of air duct shall be less than 65 mm. Before processing the galvanized air duct, use cleaning solution to remove the oil stain and dust on the surface of the plate. The cleaning solution shall be a neutral detergent, which will not damage the board surface, and will not produce dust after drying, so it will not be harmful to human health. Clean the vent pipe with cleaning solution after fabrication. After cleaning, the electric board shall be sealed in time after the white silk cloth cleaning inspection meets the requirements. The inner wall of color coated steel pipe shall be smooth, and the coating shall not be damaged during steel plate processing. The damaged parts shall be coated with epoxy resin. The galvanized air duct seamed joints, riveted joints and flange flanged corner joints shall be sealed with sealant or other sealing measures according to the design and cleaning level requirements. The sealing materials shall be isobutyl rubber, chloroprene rubber, modified silica gel, etc. The sealing surface of the air duct plate joint shall be located at the positive pressure side of the air duct wall. The production site of galvanized air duct shall be relatively closed, and the production site shall be paved with soft materials that are not easy to produce dust. The galvanized air duct shall have fewer longitudinal joints, glass fiber reinforced plastic ventilation pipes, and no transverse joints. Sand suction hose company The processing of connecting bolts, nuts, washers and rivets shall be galvanized or other anti-corrosion measures, and blind rivets shall not be used.

“ high quality Sand suction hose What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, Sand suction hose company It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.
