On September 14, 2017, the company was identified as a "designated enterprise of the People's Bank of China's prosperity survey", and on September 7, 2017, the company signed the largest equipment purchase contract: 100 Meier knitting machines will be deployed in 5 years, making it the first in China. The company's third-phase project was officially deployed, and the company's annual production capacity doubled again. With the help of the Litong e-commerce platform established in 2015, it vigorously develops domestic and international markets, and delivers Litong's products to various markets across the country and even around the world.
R4 Return Line Suitable for hydraulic suction and return lines. The interior is made of black oil-resistant synthetic rubber, the outer layer is made of oil-resistant, weather-resistant, wear-resistant black synthetic rubber, and the middle is reinforced with one or two layers of braided fibers and a layer of spiral steel wire. Continuous operation in the temperature range of 40°C to +100°C (-40°F to +212°F). Establish a technical research and development team for new technology, continue to innovate, improve the original technology, and develop new R & D ideas, walking in the international forefront. Report on the work in a timely manner, and dare to promote the merits and demerits. The value of Litong to customers is the value of service, improving product quality control, product distribution, maintaining close communication with cooperative customers and actively cooperating with customers.
Litong strictly requires itself in the development process and takes the lead in the work inside and outside the party. The service life of the sandblasting hose is much worse. The following reasons are listed: 1. Whether the bending degree of the sandblasting hose is less than the bending radius; 2. The particle size of the medium conveyed by the sandblasting hose; 3. The sharpness of the particles conveyed by the sandblasting hose; 4. The speed of the medium conveyed by the sandblasting hose; 5. The temperature and pH of the medium conveyed by the sandblasting hose; 6. The dryness and humidity of the medium conveyed by the sandblasting hose. The ultra-high pressure rubber hose has one or more layers of steel wire braided outside the bellows, and is made of rubber. Low temperature resistance (-196℃~+420℃), light weight, small size, good flexibility and so on. It is usually used to transport high temperature media such as corrosive chemical media, organic solvents, high temperature gas, hot oil, and low temperature or ultra-low temperature media.
The characteristics of high temperature hose with corrosion resistance, acid and alkali resistance can be used to transport most chemical substances, with good mechanical properties, good bending radius, aging resistance, ozone resistance, wear resistance and corrosion resistance. Its technical parameters are inner layer material Teflon / PTFE; outer reinforcement layer, high fiber reinforced fabric, double-layer surface heat treatment stable coating, outer spiral metal keel reinforcement, its working temperature range is -40 ℃ to +200℃; applicable standard EN12115
