The armored cloth steam hose is used to transport saturated steam or superheated water just like the cloth cloth steam hose. Its characteristic is that the outer surface of its high-pressure hose is made of galvanized metal wire winding, this method can effectively increase the strength of its tube body, so as to improve the pressure-bearing capacity of the steam hose. This kind of hose is often used in environments with complex working conditions, but it has high requirements for safety. Asphalt hoses are generally used for loading and unloading hot asphalt. The pipes are designed to withstand positive and negative pressure. In addition to the normal reinforcement layer, there is also a layer of spiral steel wire to support the pipe body. When negative pressure occurs during loading and unloading, the pipe will not be damaged. Press plaque.
In addition to synthetic rubber, the inner rubber can also be made of PTFE. The outer rubber layer has the characteristics of weather resistance and wear resistance. There are various forms of asphalt hose joints, and customers can assemble different joints according to different use environments. In the process of development, Litong has received the care and support of many provincial and municipal leaders, and has taken root in Henan to expand overseas markets. After more than 10 years of development, Litong has lived up to expectations and won the top ten rubber hoses in China for 8 years. Behind the honor is that Litong serves customers and is recognized by customers. Yes, but Litong is not satisfied with the status quo. It is used to expand new markets, develop new products, and set new goals every year. For China's 2025 high-end manufacturing, all staff will surely realize the Litong dream.
Litong Testing Center currently has: raw material analysis room, semi-finished product testing room, finished product testing room, pulse testing room, sandblasting testing room, assembly extraction laboratory, chemical analysis room, physical performance laboratory, salt spray laboratory, many advanced laboratories Fireproof laboratory, low temperature laboratory, wear resistance laboratory, flame retardant laboratory, atomic absorption laboratory, image measurement room and other levels, they can be assembled in all directions, etc., ensuring the transformation of product production and technological innovation. The use of a certain proportion of reclaimed rubber in the acid and alkali resistant hose can not only reduce the cost of raw materials, but also improve the aging resistance of the rubber material, thereby prolonging the performance and service life of the acid and alkali resistant hose.
However, if you want to significantly improve the aging resistance of acid and alkali resistant hoses, rubber antioxidants are essential. Generally, antioxidant A or antioxidant D is often used in acid and alkali resistant hoses used to transport dilute acid and dilute alkali solutions. In the acid-concentrated and alkali-resistant hose, the above three antioxidants are used together to further delay the aging time and prolong the service life of the acid and alkali-resistant hose. PTFE is a new type of rubber material. It has strong corrosion resistance when conveying strong acids and alkalis. The hose is super wear-resistant. This hose is mainly used for special chemicals, cooling water, waste gas and other materials. The safety performance of the hose itself is relatively high, but for safety reasons, it must be checked regularly to avoid abnormal situations.
