The characteristics of Litong chemical delivery hose - long life and wide application range

The high-strength mining hose is mainly reflected in the application of high-strength mining. The inner layer is black SBR/NBR mixed rubber with oil mist resistance, and the outer layer is green SBR rubber with wear resistance, oxidation resistance and weather resistance. Continuous operation under the constant pressure of 400psi, the middle is wound and strengthened with high tension fiber textile thread, the pipe body has good flexibility, easy to operate, and the diameter of the pipe body can be customized according to customer needs.

How to extend the service life of ultra-high pressure cleaning hoses? First, the operation, maintenance and maintenance must be carried out in strict accordance with the relevant manuals. Do not twist the hose by hand while the high pressure cleaning equipment is in operation. If it is really necessary to bend due to construction needs, the bending radius should not be too small, and it should not be bent at a small angle. Second, during the operation of the equipment, the high-pressure injection device cannot be turned on and off repeatedly, and the impact force of the hose will be damaged by frequent operation. In addition, when it is not used for a long time and does not work, the water in the hose should be drained, and the hose should be bent and coiled into a roll according to the specified size, and then placed in a horizontal state.

Litong's wear-resistant hoses are characterized by high wear resistance and long service life. A customer's equipment in Shaanxi is made of high-strength materials, which can continuously filter a large amount of sludge. And our wear-resistant pipe has the characteristics of large processing capacity, high dehydration efficiency and long service life. It is widely used in various production lines. in the solid-liquid separation industry. The selection of wear-resistant pipes in the equipment should be based on the experience of experiments and actual use, and the best wear resistance should be selected according to the actual material to ensure a longer service life.

The petrochemical hose Litong products have obtained the American Bureau of Shipping ABS certification. In the heavy industry such as shipbuilding, infrastructure, machining and manufacturing, Litong products have developed Hercules series products, which have the characteristics of low bending, high temperature resistance, high pressure resistance, etc. Super Hercules , Using hydrogenated nitrile rubber and Teflon material, under high temperature, high pressure, acid and alkali conditions, it can withstand high pressure and maintain stability, solve the trouble of frequent replacement of wearing parts for customers, and improve work efficiency. Litong chemical conveying hose has the characteristics of long service life and wide application range.

Its structure is woven from one or more layers of reinforced high-strength steel wire. The inner and outer liners of the hose are extruded and the inner liner is made of a series of compound rubbers. The tube body is soft, high strength, good elasticity and good wear resistance. Steel wire is added to the tube to enhance the overall performance of the tube. It has the characteristics of low calorific value, good elasticity and long service life. Rubber hoses have good positive and negative pressure resistance, acid resistance, alkali resistance, oil resistance, high temperature resistance, etc., and can transport more than 90% of today's chemicals. In December 2019, Litong obtained the Lloyd's refractory certification, indicating that the fire resistance of Litong API 16D hose has been recognized by the industry.

In addition, Litong API 16D hose also has the characteristics of equal diameter (total flow), and the effective diameter exceeds the industry standard by about 2 times. Greater fluid flow allows for faster and more efficient control of BOP opening and closing. The leakage current at the connection between the pipe body and the connector is avoided, so the hose has a higher safety factor.
