At present, the wear-resistant hoses on the market are divided into the following types according to the structure and pressure (A, B, C, D working pressure from low to high) four types: Type A: its working pressure is too high Between 1.5MPa and 2.5MPa (the test and blasting pressure is about 1.5 times and 2.5 times the working pressure), the inner and outer rubber components of the tube body are generally wear-resistant and weather-resistant plastics, which improve the application cost of the neutral cloth. As a reinforcement layer; Type A is relatively simple in terms of production cost and process, and has the least cost. The company was successfully listed in 2015, which is in line with my country’s development strategy. It is used in high-end industries. It gets rid of the awareness of product procurement that only recognizes international brands. In the basic material research and development industry, the company develops a variety of high-end mixed rubbers to ensure high-end equipment, and introduces overseas high-end experimental instruments and production line equipment together to gain the sales market for Litong and carry out the corporate vision of Litong slowly facing the world. LT301API 7K series products – high wear-resistant alkalizing and hydraulic fracturing plastic hoses, mainly used to transport water-based, oil-based, foam plastic, Acid-based and other fracturing fluids, the internal structural raw materials are made of German brand ultra-high molecular polyethylene (UPE) raw materials, which have great chemical stability and wear resistance; the outside is made of wear-resistant and weather-resistant styrene-butadiene rubber, which conforms to international API 7K specification. Next, the high pressure rubber tube is soft and has a small bending radius, and the internal structure of the tube body improves the layer The adhesive and the reinforcing layer in the new high-pressure resin tube are basically non-adhesive, even if the manufacturer chooses raw materials such as adhesives as compensation; but this is a disadvantage after all. The key to this problem lies in the insufficient precision of the plastic hose crimping equipment at this stage, and the second is caused by the unlimited quality of the tee joint.

In March 2018, the bonding of PTFE plastic was successfully completed. The improvement of this process not only overcomes the shortcomings of PTFE pipe body in use, but also creates more main uses, which promotes Teflon Plastic hoses have been extremely used in many industries such as organic chemistry, pharmaceuticals, food, chemical plants, etc., which not only shows the excellent technology of Litong hydraulic press in the processing technology of rubber hoses, but also completes a milestone in plastic research and development. It has become the first manufacturer in the world to complete the bonding of PTFE raw materials. There are many types of high-pressure wear-resistant pipes that people often talk about. This time, we mainly talk about the plastic hose of concrete structure cryogenic pump. It is a kind of plastic hose for transporting concrete. It is easy to assemble and easy to operate. , its wear resistance and oxidation resistance characteristics are further improved, the efficiency of mixing slurry transportation is many times higher than that of traditional mud pipes, and it is more suitable for on-site construction of cast-in-place concrete. It has become a popular plastic hose for cast-in-place concrete on the spot. .
