The company has reached an agreement with the customer on the warranty of Litong rubber hoses and hose joints. Litong always insists on "improving the quality of my country's hydraulic pipeline system, reducing the user's cost of use, and saving resources for the society" to strengthen party education, strengthen ideological and political work, and contribute to production work. It provides a strong spiritual power and ideological guarantee, and orders for military-grade products should be treated with a more rigorous working attitude. There is also a security issue. The use of the sandblasting machine itself is usually used to complete the sandblasting process, so many large enterprises have their own sandblasting rooms. What should I do when it is dangerous to use the sandblasting room? There is also a security issue. The use of the sandblasting machine itself is usually used to complete the sandblasting process, so many large enterprises have their own sandblasting rooms. If it is dangerous to use the sandblasting room, what should we do? When the accident occurs, because the sandblasting machine adopts high-pressure wear-resistant pipe, the pipe wall is very dangerous, and the operator is out of danger as soon as possible, and the ventilation equipment provides fresh air to the operator through the protective clothing and helmet. The excellent wear resistance of UPE concrete wear-resistant hose determines its specific and better wear resistance as the inner rubber layer of the wear-resistant hose. Litong has the patented technology of UPE with rubber layer bonding technology. Due to its excellent chemical stability, it does not react with most substances, and there are few UPE materials that can be bonded in reality. Litong's patented technology not only realizes the practical application of pipes and UPE, but also reflects the extraordinary combination of inner walls. The effect has been unanimously recognized by customers. A steel plant in Shandong needs a batch of high temperature rubber hoses. The equipment used in the steel production process includes continuous casting equipment, which is divided into electric oven converters and thermal oven converters. The requirements for the hose must be a shielded appearance for thermal insulation, temperature reduction and fire protection. Qualified pressure must be obtained to use oil pumps and pumping stations. The high-temperature resistant series hoses developed by Litong can safely transport 260°C saturated steam, petroleum-based hydraulic oil, and high-quality hot water hoses, mainly in the fields of petroleum, construction machinery and smelting. The rotary drilling hose is used between the top of the riser and the upper and lower rotary joints, and the marine mud transportation hose is used for ultra-high pressure mud transportation between the barge and the offshore drilling platform. The length is usually more than 135m, and the shock absorption hose is short (9) m or less) is used between the pump and the drilling rig i.e. the riser manifold to accommodate different shafts and isolate vibrations. Structural editing. It consists of inner rubber layer, inner rubber protective layer, middle rubber layer, steel wire winding layer and outer rubber layer. Teflon hose is a kind of food grade hose with high temperature resistance, acid and alkali resistance, corrosion resistance, with high chemical stability: can withstand aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, nicotinic acid, organic acid, strong All strong acids such as alkalis, strong oxidizing agents, reducing agents and various organic solvents. Ideal for high-purity chemical feeds.
