Another type of Litong's wear-resistant hose is custom developed for special industries, that is, LT1306UPE ultra-abrasive concrete conveying hose, because it uses a special inner rubber material UPE (ultra-high molecular polyethylene) as its wear-resistant layer. Therefore, in terms of service life, it can reach several times that of ordinary wear-resistant hoses. It can pass most corrosive mixed media such as acid-base, hydrogen sulfide, etc., and its excellent characteristics make it free from the corrosion of acidic substances in concrete or mud. Luohe Litong Technology Co., Ltd. processes 15,000 tons of rubber annually, produces 40 million meters of hydraulic hoses, petrochemical and other industrial hoses, and 20 million rubber seals and related products. It is expected that after the project is fully put into operation in 2024, the production and sales volume of various pipes will reach 120 million meters, the production and sales volume of compound rubber will reach 35,000 tons, and the number of gaskets and related products produced and sold will increase to 10 million pieces. The output of the device will reach 50 million pieces, and the output value is expected to exceed 2.5 billion yuan.
During the tunnel construction process, the shield machine is like a "big mac" gluttonous snake digging in the soil layer, its head is like a disc full of teeth spinning, swallowing soil and stones. In the long barrel of nearly 100 meters, the mud circulation system, as the core part of the shield machine, is the key to maintaining the stability of the face and conveying the muck. The mud circulation pipeline is the main carrier of slag discharge in the mud circulation system of the shield machine, which directly affects the lift of the slurry pump of the conveying system. While the machine is excavating along the axis of the tunnel, the purpose of rapid slag discharge is achieved. High-temperature and high-pressure steam transportation is a dangerous industry to ensure the safety of construction workers and construction. Litong steam hose products can be safely transported and transferred. The working pressure and temperature are at 270PSI and 430°F (+220°C) saturated steam, high-temperature liquid transportation, and water-vapor mixture. , etc., Litong products can fully meet the application in special environments, the production of EPDM mixed collagen materials and their products are leading in the high temperature resistance industry. </div><div>The core component of Litong's ace product hose is a multi-layered reinforced rubber hose. The inner lining and outer layer of the hose are extruded, and the inner lining is made of a series of compound rubber. Once the hose is formed, it is machined. Machining is the last step in hose manufacturing to ensure the product meets tight tolerances. Precision extruded hose is a high-purity natural rubber that is more wear-resistant, free of impurities, and lighter in weight. Resistant to positive pressure and negative pressure, thickened nylon cloth, the support and anti-pressure effect are significantly improved. The service life is improved. After tens of thousands of friction experiments, the service life is 3 times longer than that of ordinary rubber hoses.
The frosted UPE film is made of high-quality raw materials, with a minimum molecular weight of 840, which meets ISO requirements. According to customer requirements, it can be made into any thickness of 0.0.08-3mm. At the same time, because of its low density, light weight, good stability and long service life, it is more wear-resistant than traditional Teflon, and its high temperature resistance is only It is inferior to Teflon material, so it is the first choice material that can gradually replace Teflon.
We will update more about -Teflon- gradually, so stay tuned.
