Welded pipe joints are widely used in pipeline connections in various fields due to their sturdy structure, good sealing, and strong pressure resistance. The following are some common application scenarios:
Industrial manufacturing field
Petrochemical industry
Used to connect refining units, chemical reaction vessels, pipeline transportation systems, etc., for transporting crude oil, chemical raw materials (such as ethylene and benzene), corrosive media (such as acid and alkali solutions), etc. For example, in oil pipelines, welded pipe joints can ensure stable transportation of crude oil under high pressure, avoiding safety accidents caused by leaks.
Power and energy industry
Suitable for connecting steam pipelines, cooling water pipelines, and fuel delivery pipelines (such as natural gas and coal powder pipelines) in power plants. For example, in high-temperature and high-pressure steam pipelines, welded pipe joints can withstand high temperatures and pressures, ensuring efficient steam transmission.
Metallurgical Industry
Used to connect cooling water pipelines, hydraulic system pipelines, and pipelines for transporting gases such as oxygen and nitrogen for steelmaking furnaces and rolling mill equipment. For example, in the hydraulic system of a rolling mill, welded pipe joints can ensure the sealed transmission of high-pressure hydraulic oil and support the movement of the rolling mill rolls.
Mechanical Engineering and Equipment Field
Hydraulic and Pneumatic Systems
Widely used in hydraulic pipeline connections of construction machinery (such as excavators, cranes) and machine tool equipment (such as lathes, milling machines), transmitting hydraulic oil to drive components such as hydraulic cylinders and hydraulic motors. For example, the hydraulic arm movement of an excavator relies on the reliable connection of welded pipe joints to ensure no leakage of high-pressure hydraulic oil.
Compressor and pump equipment
Used to connect the intake/exhaust pipelines of compressors and the inlet and outlet pipelines of pumps, such as the high-pressure air pipe of air compressors and the water supply pipeline of water pumps. The high strength of welded pipe joints can withstand high-pressure impacts from gases or liquids.
In the field of architecture and infrastructure
Water Supply and Drainage System
Welded pipe joints can be used to connect large-diameter steel pipes in fire and industrial water pipelines of large buildings, ensuring stable water flow and no leakage. For example, in the fire sprinkler system of high-rise buildings, welded pipe joints can withstand water pressure, ensuring timely water spraying in case of fire.
Heating and gas system
Connection of steam pipelines for central heating and gas transmission pipelines for residential areas. For example, in urban gas pipeline networks, welded pipe joints ensure gas sealing through high-quality welding, avoiding safety hazards caused by leaks.
Aerospace and Defense Fields
Aircraft Hydraulic and Fuel Systems
Used for connecting hydraulic pipelines of aircraft landing gear and fuel supply pipelines of engines, requiring pipe joints to maintain sealing and firmness in harsh environments such as high altitude, low pressure, and vibration. For example, in the fuel system of fighter jets, welded pipe joints need to meet the requirements of anti vibration and high temperature resistance to ensure flight safety.
summarize
The application scenarios of welded pipe joints cover multiple fields from industrial production to high-end manufacturing, from infrastructure to aerospace. Its core advantage lies in achieving high-strength connections and reliable seals through welding processes, especially suitable for high-pressure, high-temperature, corrosive or high safety requirements. In practical applications, it is necessary to select the appropriate model based on the characteristics of the medium, pressure and temperature parameters, and industry standards, and ensure that the welding quality meets the requirements.
