Common working conditions of concrete conveying pipes

 Concrete conveying pipe is a relatively common one. Generally, there are three specifications, 4", 5", 6" (2", 3" specifications are rare). The pipe body is generally 3m long, and the general concrete hose is carried out at room temperature. Operation (-29℃~+80℃), the working pressure ranges from 2MPa to 8.5MPa. The price is also divided into several grades according to the performance of the pipe body. The cord fabric is used as the reinforcing layer, because the pressure requirements are relatively low. , so the price is the most favorable, but its lifespan is also short. In 2013, Litong Testing Center was awarded the title of high-pressure hose technology research center awarded by the Science and Technology Department of Henan Province. In July 2016, Litong Testing Center was the first official testing center in China. A professional rubber hose R&D center that has obtained the laboratory accreditation certificate issued by China National Conformity Assessment Agency (CNAS). The certificate confirms the testability of Litong vulcanized rubber and rubber hose, indicating that Litong is qualified to test and evaluate vulcanized rubber and rubber hose The quality of the inspection is fair, accurate and authorized. In the history of the development of the cord blasting pipe, the selection of the skeleton layer has been from the previous cloth to the now widely used cord and steel wire. The processing technology of the cloth is It is wrapped in layers of cotton cloth, and this process has been basically eliminated at home and abroad; foreign countries basically use cord sandblasting pipes, while domestic use both cord and steel braid. Winding; the steel wire is braided or wound with steel wire. Now there are many kinds of sealing products on the market, and the work requirements are various, such as good heat resistance, oil resistance, and resistance to chemical corrosion. Pressure is also a reference factor. These stringent requirements require the improvement of product production technology, so our technical department thought of using rubber seals for mechanical seals, which can not only meet all the above requirements, but also have elasticity and lower compression set. It is the technical advantage of Litong Hydraulics. What is the high-pressure anti-wear structure? The anti-wear tube is made of steel wire wound wear-resistant rubber tube, and the reinforcement layer is a high-strength steel wire winding layer. After special treatment, most of the inner layer is UPE, and the outer layer is polyamide or Polyurethane, it has extremely small liquid resistance, wear resistance, small volume expansion, chemical corrosion resistance, light weight and small outer diameter, so it is generally used for material transportation or chemical mixture transportation in the environment. Pipe joints are selected from carbon steel or Stainless steel, compactor and workmanship.High quality hot air hose flexible lightweight hose at a good price for competitive applications where the most important operating characteristics are not a major issue.This hose Mainly used to deliver hot non-oily air up to 163°C (325°F) from manifold blowers on dry haul trucks or compressors in factories to storage tanks for dry bulk material transport. Designed to eliminate moisture build-up in dry bulk products. Stay tuned for more updates on chemical transfer pipes.
