peculiarity
High strength: Able to withstand high pressure, generally made of high-strength materials, such as alloy steel, stainless steel, etc., to ensure safety and reliability in high-pressure environments.
Good sealing: with excellent sealing performance, it usually adopts special connection methods and sealing structures, such as welding, flange connection, ferrule connection, etc., with sealing elements such as sealing gaskets and sealing rings to prevent fluid or gas leakage.
Corrosion resistance: Depending on the conveying medium, the high-pressure pipe needs to have a certain corrosion resistance. For example, when transporting corrosive media in the chemical industry, corrosion-resistant stainless steel or high-pressure pipes lined with corrosion-resistant materials are used.
High precision: The manufacturing accuracy of high-pressure pipes is required to be high, and the dimensional accuracy of pipe diameter and wall thickness is strictly controlled to ensure the pressure resistance of the pipeline and the stability of fluid transportation.
Fields of application
Industry: In the petrochemical industry, it is used to transport high-pressure fluids such as crude oil, natural gas, and chemical raw materials; In the power industry, it is used for steam transportation in thermal power generation, high-pressure water pipelines in hydropower generation, etc.; In the metallurgical industry, it is used for high-pressure water cooling systems and oxygen delivery pipelines for blast furnaces, converters and other equipment.
Machinery: All kinds of hydraulic equipment, such as hydraulic presses, injection molding machines, construction machinery, etc., all need high-pressure pipes to transmit high-pressure oil to achieve power transmission and precise control of equipment.
Aerospace field: The hydraulic system and fuel system of the aircraft all use high-pressure pipes, which require the pipes to have the characteristics of high strength, light weight, fatigue resistance, etc., to meet the strict requirements of aerospace equipment.
Selection of high-pressure pipes
High-pressure pipes play a key role in various high-pressure fluid conveying systems, and their quality and performance are directly related to the safe and stable operation of the whole system. When selecting and using high-pressure pipes, it is necessary to reasonably select the material, specifications and connection methods of pipes according to specific working conditions and requirements, and install, maintain and test them in strict accordance with relevant standards and specifications.
FAQ
Q: What may be the cause of bulging pipe body?
A: The inner hose is aging, the braid is broken, or long-term overpressure is used.
Q: Frequent cracking at the bends, where is the common problem?
A:The bending radius is too small, the material has poor fatigue resistance or frequent bending.
Q: How to deal with scaling on the inner wall that causes the diameter to become smaller?
A:Rinse with special cleaning agent, and in severe cases, replace the new pipe and check the cleanliness of the medium.
