At present, the rapid development of various industries also promotes the continuous innovation of technology and the wide application of various facilities, and various wear-resistant pipe fittings are an indispensable special purpose in the process of raw material storage and transportation tool way. High-pressure wear-resistant hoses are relatively widely used in industrial production infrastructure, and they are often seen in other industries, such as mortar transportation or raw material suction and discharge, etc., with a variety of excellent characteristics. In order to improve the replacement efficiency of cement mortar and ensure that the cementing truck can effectively carry out the daily tasks of cementing engineering construction under high pressure, LT301C high-pressure concrete hose is made of 4-6 layers of extremely strong and highly flexible stainless steel wire or galvanized steel wire rope. The improved layer has the characteristics of high pressure resistance and elongation resistance, which can effectively improve the operation efficiency and ensure the safety of the operation. Its outer viscose is made of wear-resistant and weather-resistant styrene-butadiene rubber, which has the characteristics of flame retardancy and ozone aging resistance, which greatly prolongs the service life and service cycle of the hose (supports customized high wear-resistant UPE outer cladding). The key components of the gold medal hoses under the Litong Group are the double-layered and differentiated lifting plastic hoses. The lining and surface of the hose are extruded, and a series of compound rubbers are used for the lining. Once the hose is formed, it is machined. Machining is the last process in the manufacture of hoses to ensure that the product meets the precise tolerances. The high-precision extrusion hose is a high-quality natural plastic, which is more resistant to wear, has no residue, and has a lighter net weight. Positive pressure and negative pressure resistance, thickened nylon, the actual effect of supporting points and compressive strength is significantly improved. The service life is improved, and the service life is 3 times longer than that of ordinary plastic hoses through tens of thousands of friction tests. EPDM hose advantages and disadvantages: anti-aging, insulation properties and resistance to reactive oxygen species are prominent. Excellent weather resistance, active oxygen resistance, high temperature resistance, corrosion resistance, water vapor resistance, color tone reliability, electrical properties, oil-filled solubility and fluidity at room temperature, suitable for all kinds of positive and negative chemicals such as alcohol, acid, alkali, oxide , refrigerants, detergents, animal and vegetable oils, ketones and greases have good resistance to resistance; but the reliability of fatty and aromatic organic solvents (such as automotive gasoline, benzene, etc.) and mineral oil is weak. The performance under the long-term action of concentrated acid also needs to reduce the water vapor resistance and evaluate it better than its temperature resistance.

In the application field of oil drilling and production, API7K is a common standard, and the high-pressure salon movable belt is a pipeline that meets this standard. This part of the hose is a soft joint connecting the drilling engineering platform and the mud treatment equipment. Generally, DN102 type hose is used as the medium. The core result is that the inner viscose (HNBR, NBR) is wound with several layers of stainless steel wire, and the outer viscose is weather-resistant and abrasion-resistant plastic; the hose wrapped with double-layer stainless steel wire is used, which has a higher working pressure. It can be pressed above 100Mpa. On the cornerstone of the original various hydraulic machine hose product clusters, our company has designed and manufactured more than one million single-pulse high-strength winding series hoses, innovative and upgraded ultra-flexible ultra-high-pressure high-pressure low-bending series hoses, The ultimate value high pressure cleaning hose, the 400MPa ultra-high pressure epoxy resin cleaning series product hose and the UPE high wear-resistant concrete transportation series product hose with the reputation of “Anti-Abrasion King” preferred by customers, the characteristics and quality of the products have been recognized by countries all over the world. The affirmation of construction machinery customers.
