HFIW Pipe
High-Frequency Induction Welded (HFIW) pipes
High-Frequency Induction Welded (HFIW) pipes are widely used in industries that demand strength, reliability, and precision. Known for their superior weld quality and cost-effectiveness, HFIW steel pipes are extensively applied in oil & gas, water transmission, construction, and automotive industries.
At Emirerri Steel, we manufacture and supply premium-quality HFIW pipes that meet international standards such as API, ASTM, and EN. Our pipes are trusted for their dimensional accuracy, smooth surface finish, and long-lasting performance in critical applications.
What is an HFIW Pipe?
An HFIW pipe is produced using a high-frequency induction welding process, where an induction coil generates a strong electromagnetic field that heats the edges of the strip. The heated edges are then forged together under pressure, forming a weld without using any filler material.
This advanced process ensures that the weld zone has high strength and durability, making HFIW steel pipes an ideal choice for both structural and fluid transportation applications.
Key Features of HFIW Pipe
High weld strength and consistency
Smooth internal and external weld seam
Cost-effective production with high efficiency
Suitable for both low and high-pressure applications
Wide range of diameters and thicknesses available
No filler material required, ensuring a clean weld
Manufacturing Process of HFIW Pipe
The production of HFIW welded pipe involves the following steps:
Raw Material Selection – Hot-rolled steel strips or coils are prepared.
Forming – The strip is shaped into a cylindrical form.
High-Frequency Induction Welding – The edges of the strip are heated and fused under pressure.
Sizing & Shaping – Pipes are sized and shaped for dimensional accuracy.
Non-Destructive Testing – Ultrasonic and eddy current testing ensure weld integrity.
Finishing – Pipes are cut to desired lengths and undergo surface treatment if required.
Applications of HFIW Steel Pipe
Thanks to their versatility and cost-effectiveness, HFIW pipes are used in a wide range of industries:
Oil & Gas Transmission – Pipelines for crude oil, petroleum products, and natural gas.
