The inner layer is two kinds of multi-functional chemical delivery pipes, PTFE and UPE. Different types of inner layers can be selected according to different controls. This is a customized hose with good bending radius and acid and alkali resistance, which can transport 98% of For industrial chemicals, the middle layer adopts a single or two-layer spiral steel wire skeleton layer, which can well prevent the absorption operation due to the negative pressure flattening the tube. Pipes can be customized from 9mm to 200mm. Low temperature resistance, can be used normally at -30 degrees Celsius. In 2017, we achieved the best half-year performance in the history of Litong: Super Hercules oil drilling hose 7 series products remained stable K/16C products have obtained API certification, newly developed Teflon high, medium and low pressure will be standard hoses. The name translated into "KING HOSE" in Chinese is "King of Hose". The third phase of Litong was put into operation in 2019. The Xifa Compound Rubber Building of Litong Fluid Intelligent Industrial Park has been completed. The annual production capacity of GK190E is 10,000 tons. The automatic rubber mixing intelligent production line was successfully put into operation. The impact of the high-pressure cleaning pipe plunger pump on the high-pressure water flushing the surface water will be deprived of the dirt that is larger than the dirt attached to the high-pressure water surface of the power plant, and the cleaning equipment for cleaning the surface has been realized. Because of the dirt cleaned with high pressure water jets, unless it is stubborn oil, the high pressure cleaning tube only needs to add a small amount of detergent or general dirt with sufficient foam water pressure. Litong adheres to the principle of "integrity first, users first" and leads all Litong employees to overcome difficulties continuously, and at the same time obtains Russia-GOST-petroleum certification and Lloyd's refractory certification. The company's products are used in harsh environments such as high risk, high pressure, and high temperature, which is enough to prove its reliability. For more than ten years, Litong Hydraulics has insisted on taking the opportunity of continuous innovation and development to promote product technology innovation and speed up the development of new products. The characteristics and structure of the slurry conveying pipeline: with polyurethane and butyl rubber as the basic raw materials, after adding special reinforcing agent, the rubber is in a transparent state, and has the characteristics of super wear resistance, toughness and high pressure resistance. The wear resistance index is 2-3 times that of ordinary sandblasting pipes. Reinforcing layer: Sandblasting pipe is the reinforcing layer, which has good elasticity and strong pressure resistance. The sandblasting pipe is copper-plated rubber hose. good feature. The scope of application of oil hose products: oil tankers, oil tanker refueling, oil tanker oil discharge in oil depots, large and medium-sized petrochemical refineries, large and medium-sized animal and plant refineries, oil tankers, railway train refueling, petrochemical oil storage and transportation companies and other large and medium-sized port terminals. 1. Determine the pipe joint for the oil hose. The oil hose joint is installed outside the pipeline, and its tightness cannot be adjusted.
