A customer request: The tube can be rolled up mechanically. Length: 30~100m, inner diameter 150mm, pressure 350KG Flow rate: 300~450 cubic meters per hour Medium: underground gravel slag, (two rounds of grinding), about 30% of the slag, the largest conveying particle is oval Gravel (sharp edge), usually used for pipes. It will be replaced in a few days. After using the latest Litong wear-resistant pipe, the customer’s production efficiency has been greatly improved. High-pressure hoses are widely used in 1. Textile, chemical fiber, printing and dyeing, petroleum, chemical industry, steel, gas, air conditioning, automobile, fire protection, urban water supply, construction, metallurgy and petrochemical fields; 2. Transporting high-temperature gas, hot oil and other high-temperature media. (For example: hot steam, heat transfer oil, etc.); 3. Transport low temperature or ultra-low temperature medium. (For example: liquid atmosphere) 4. Transport water, steam, oil and other media in high temperature environment. (For example: water vapor system and hydraulic system in coking, steelmaking, continuous casting equipment).
On February 18, 2020, Chairman Zhao Hongliang personally presented a golden sunflower road to front-line workers. The study found that the main raw material of golden sunflower tea is organically grown golden sunflower. Through low temperature processing, the proportion of flowers, seeds, leaves and roots can be scientifically adjusted, so as to give full play to the bioflavonoids and linseed oil contained in different parts of golden sunflower. The role of sour flax. Acid, high polysaccharide gum, organic selenium, vitamin E and other high-density nutrients can rapidly improve blood circulation, activate cells, improve the functional status of five organs and enhance immunity. This is a critical moment to end this pandemic. Corrugated PTFE hoses are suitable for conveying compressed air, esters (such as grease), viscous substances (such as glue), corrosive chemicals, and fluids such as oil at high temperatures. The inner part is made of corrugated PTFE, and the outer part and the reinforcement layer are woven with high-strength 304 stainless steel wire. , The inner diameter of the pipe can be customized according to customer requirements. What are the advantages of PTFE hose? 1. Excellent resistance to atmospheric aging, radiation resistance and low permeability. It can be exposed to the atmosphere for a long time, and its appearance and function remain unchanged; 2. Excellent high and low temperature resistance. PTFE hose has little effect on temperature, wide temperature range, melting point of 327℃~342℃, and can work at +250℃~180℃ for a long time; 3. Excellent corrosion resistance. It can withstand the effects of molten alkali metals, fluorinated media, strong oxidants, reducing agents and various organic solvents. Reasons for bulges and cracks in high-temperature steam rubber hoses: 1. The steam hose loves bulging because the internal temperature of the steam hose is high, and the expansion coefficients of the inner and outer rubber are inconsistent; 2. The outer rubber of the steam hose is always cracked, one of the reasons is The outer rubber is not resistant to high temperature. Another reason is that the external temperature is high, and EPDM rubber is not resistant to dry heat.
