High frequency welded pipe
High-Frequency Welded Pipe (HFW Pipe) is a type of welded steel pipe produced by using the skin and proximity effects of high-frequency current to rapidly heat the edges of a steel strip to a molten state, followed by pressure welding.
Round Pipes
Round HFW pipes are the most widely used, serving industries like oil & gas, construction, and machinery.
Rectangular Pipes
HFW rectangular tubes: high-strength, lightweight solutions for construction and industrial applications.
Profiled Pipes
HFW profiled pipes provide lightweight strength in custom shapes for industrial applications.
Application Fields of Round Pipes
Widely used in:
- Building plumbing & potable water systems
- Oil/gas (drilling, refining, transportation)
- Specialized industries: • Geological drilling • Chemical processing • Construction machinery • Aerospace/automotive manufacturing • Boilers, medical devices • Furniture/bicycle production • Fitness equipment
Domestic water supply
For building water supply and drinking water lines.
Construction support systems
Temporary structural supports needed for construction.
Domestic applications
Common in furniture, bicycle, and fitness equipment manufacturing.
Applications of HFW Rectangular Pipes
High-frequency welded rectangular tubes are widely used in various fields due to their high strength, lightweight, precise dimensions, and excellent formability.
Architectural & Structural Engineering
Structural supports (beams, columns, trusses) for industrial buildings, warehouses, stadiums.
Furniture and Daily Facilities
High-frequency welded rectangular tubes are widely used in furniture and simple storage racks.
Power and Energy Transmission
HF-welded rectangular pipes for power grids—ideal for transmission towers & substations due to conductivity & stability.
Applications of HF-Welded Shaped Pipes
HF-welded profiled pipes: Automated production, stable welds, ideal for complex industrial shapes.
Construction and Machinery
Applications: Civil building components (steel windows/doors), agri-machine parts, conveyor rollers.
Industrial Equipment
Widely used in refrigeration equipment (e.g. AC condensers), solar water heater tubes, and plumbing pipes/fittings.
Special Scenarios
HF-welded profiled pipes are also widely used in water supply/drainage pipes and fittings (nozzles, faucets, etc.).
