Since the establishment of Litong Hydraulic Technology in 2003, after 19 years of ups and downs, Litong Hydraulic Technology has gradually made a name for itself in the rubber hose industry, and has gained a good reputation in the industry for its honesty and trustworthiness, and the principle of customer first. The self-developed high-pressure oil pipe self-owned brand Super Hercules has the characteristics of high pulse, high pressure, long life and low bending. In terms of super wear resistance and corrosion resistance, PTFE multifunctional high and low pressure hoses and UPE multifunctional high and low pressure hoses have also…
Process requirements for steel wire wound high pressure hose
There are many types of high-pressure hoses, and different types have different functions. Let’s take a look at the process requirements of wire-wound high-pressure hoses.1. Before winding, the inner tube should be checked one by one, and those that do not meet the process requirements should be returned to the previous process.2. During the winding process, strictly follow the number of steel wires, winding stroke and winding outer diameter specified in Table 3 and Table 4 of the process table.3. When winding, the tube should be twisted at the same time to prevent the uneven diameter of the winding caused…
Classification and characteristics of high temperature steam hose – high pressure hose
(1) Application: It is used for conveying saturated steam or superheated water at 165℃~220℃. It is suitable for steam cleaner, steam hammer, flat vulcanizer and injection molding machine and other hot pressing equipment as flexible pipeline. (2) Features The inner and outer rubber layers of the high-pressure hose are made of synthetic rubber with excellent heat resistance. The tube body has the characteristics of softness, lightness, good flexibility and high heat resistance. (3) Classification and characteristics of high temperature steam hoses: Cloth steam hose: 1. Application: It is suitable for conveying saturated steam or superheated water not higher than…
Specific requirements for use, storage and custody of ultra-high pressure hoses
(1) When the ultra-high pressure washer is working, the hose must not be twisted, and try to avoid bending. If bending is necessary, ensure that the bending radius is not too small, generally not less than 15 times the outer diameter of the pipe, otherwise the outer steel wire of the reinforcement layer will be stretched and the inner steel wire will be compressed, thereby reducing the entire ultra-high pressure hose. Compressive strength, which ultimately affects the service life of the hose. (2) When the ultra-high pressure washer is in working state, the ultra-high pressure hose cannot be crushed…
How to choose hoses for petrochemical needs
In the petrochemical industry, which is a mining and experimental industry, either there is no problem, and once there is a problem, it is a big problem. Therefore, the safety of production is the most important. API certificate is our requirement for security. In the petrochemical industry, especially the highly corrosive chemical industry, it is necessary to use a large number of Teflon products to transport materials, which is a necessary condition to ensure long-term safe production. Teflon hoses and fluorine-lined joints not only meet the functional needs of users, but also achieve excellent performance in cleanliness and durability. …

How to use the acid hose in acid fracturing?
2022年7月12日
Stress crack acidification is called acid stress. In acid pressure construction, if acid pressure is used directly, acid is not only a pressure crack fluid, but also a liquid that reacts with the rock wall of pressure cracks; if non-reactive pre-hydraulic pressure cracks are used, the acid will flow along the water Cracks flow and react with cracked walls. Because of the uneven ground, the reaction between the cracked wall and the acid is irregular. This acid-etched rock wall will form an acid-etched earthworm hole with high conductivity after the fracture is closed, thereby improving the seepage capacity of…

Confirm selection of hose suitable for conveying steamThe category of the hose should be printed not only on the packaging, but also on the body of the hose in the form of a trademarkTo correctly identify the area where the steam pipe is useda) What is the pressure of the steamb) Whether the maximum working pressure can be reachedc) What is the temperature of the steamd) What is the humidity and dryness of the steame) how often is usedf) What are the external conditions for the hoseSpilled and corrosive chemicals attached to the hose have a destructive effect on the…
EPDM and NBR
EPDM rubber is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It only contains unsaturated double bonds in the side chain, so it has excellent aging resistance such as ozone resistance, heat resistance and weather resistance. Foreskin and high-voltage, ultra-high-voltage insulating materials. It can also manufacture light-colored products such as shoes and sanitary products. The natural color usually said in the industry refers to black.Nitrile-butadiene rubber (NBR) is a copolymer of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and…
Good rubber properties determine the market of rubber product manufacturers
For us, rubber products are already a product that can be seen everywhere, and rubber products also play a powerful role in life. Early rubber is the latex obtained from rubber trees, rubber grass and other plants. High-elastic polymer compounds are divided into natural rubber and synthetic rubber, such as automobile tires, industrial products, plastic products, etc. The annual production and processing volume of rubber is particularly large. According to this trend, it is far from impossible. Meet the current production requirements. Such is the case with rubber seals, which are a type of universal basic part in sealing…
