Ordinary liquid hoses are usually made of polyethylene, that is, plastic materials, but plastic materials are usually not wear-resistant, so rubber materials are needed to produce high wear-resistant hoses. UPE material in composite rubber material has high wear resistance, certain corrosion resistance and excellent comprehensive performance. Therefore, UPE high-pressure wear-resistant hose has been widely used in today's production and life. At high temperature, steam will seriously affect all types of rubber hoses. Therefore, temperature must be considered when selecting steam hoses, which is very important for the use and maintenance of hoses. Higher steam temperature and pressure will degrade some reinforcing materials used in the hose, which will greatly affect the performance of the hose. Therefore, selecting an appropriate steam hose can not only avoid unnecessary safety hazards in use, but also prolong the service life of the steam hose to a certain extent. PTFE hose has been widely used in water supply pipeline system and gas transmission pipeline system, but in recent years, the market share of PTFE pipeline system in gas transmission field is almost zero, and the consumption of water supply system has also declined slightly However, the consumption of PTFE hose in non pressure pipeline systems such as drainage, sewage and waste discharge systems has increased steadily, mainly because the production of PTFE raw materials is less dependent on crude oil than other thermoplastics, making its production cost relatively low. On July 13, 2013, Litong held the first oath conference "zero defect day of product quality", emphasizing that "without quality, everything is negative". August 2013, Zhao Hongliang, President of the company, proposed The idea of "sample production \ '\' means that all products on the production line can be used as samples for customers, which fully reflects the company's emphasis on production. Product quality. In September 2013, the steel wire braided hose pulse PK competition was held. The wear-resistant pipe is easy to obtain and widely used, but its rigidity is poor, so it is not suitable for the chemical process piping system and height with supply and demand, flammability, explosion and high vacuum requirements. In order to improve the welding efficiency Quality. The wear-resistant pipe shall pass the pressure test and air tightness test before leaving the factory. What is a high-pressure wear-resistant pipe? What features does it have that are not usually contained in rubber tubes? High pressure wear-resistant pipe is a kind of rubber hose produced by new wear-resistant technology. With the continuous development of society and the continuous improvement of industrial requirements, wear-resistant rubber has gradually become an indispensable wear-resistant material in automobile, petroleum, printing and other industries. Rubber has good oil resistance. Its oil resistance is much higher than that of plastic or nylon, and it is wear-resistant and sealed. The disadvantage of NBR is that it can not insulate ozone and aromatic, halogenated hydrocarbons, ketones and ester solvents.
