HFW Low Temperature Resistant ERW Pipe 76mm-660mm Cold Region Project Tube

Product Title

HFW Low Temperature Resistant ERW Pipe 76mm-660mm Cold Region Project Tube / Low Temperature Impact Resistant High Frequency Welded Steel Pipe

Brief Introduction

HFW Low Temperature Resistant ERW Pipe is specially engineered for engineering projects in frigid and cold regions. Manufactured by advanced high-frequency welding technology, this steel pipe adopts low-temperature toughness optimized steel coil as raw material. Through precise forming, online weld normalization and strict low-temperature impact testing, the pipe maintains stable mechanical properties and prevents brittle fracture under sub-zero working environments.

With outer diameter ranging from 76mm to 660mm, this cold-resistant tube delivers reliable performance for structural support, fluid transportation and pipeline systems in areas with long winters and extremely low ambient temperatures. It can withstand drastic temperature fluctuations, frost heave stress and cold cyclic loads. The product complies with international standards, supports customized wall thickness, fixed length and surface anti-corrosion treatments. It is an ideal tubular material for cold-region infrastructure, oil & gas auxiliary piping, municipal waterworks and industrial construction projects. Hebei Huayang implements full-process quality inspection to guarantee low-temperature performance consistency for bulk cold-area engineering orders.

Product Parameters

Production Process & Performance

Low-Toughness Optimized Raw Material Selection We select special low-temperature steel coils with fine grain structure. Raw materials pass chemical composition analysis and Charpy V-notch impact test at specified low temperature before entering production. This eliminates the risk of cold brittleness from the source, which is the foundation for cold-region project application.

HFW High-Frequency Welding Continuous strip forming and high-frequency resistance welding without filler metal. Inner and outer welding flash are removed by online scarfing to make weld flush with base metal. The forming process controls cold forming strain to avoid residual deformation that may degrade low-temperature toughness.

Online Weld Normalization Heat Treatment This is the core procedure for low-temperature resistant ERW pipe. The weld and heat-affected zone are subjected to normalization treatment to refine grain structure, eliminate welding residual stress and balance the mechanical properties between weld seam and base metal. It significantly improves the low-temperature impact resistance of welding zone and avoids brittle cracking under low temperature and external load.

Precision Sizing and Straightening Multi-stand sizing mill ensures uniform wall thickness and high dimensional accuracy. Full-length straightening reduces bending stress. Consistent pipe geometry helps the pipeline resist frost heave and uneven ground settlement in cold zones.

Full Batch Inspection & Low-Temperature Performance Test 100% online ultrasonic non-destructive testing for weld seams. Each batch undergoes Charpy V-notch low-temperature impact test, tensile test, bending test and hydrostatic pressure test. Test records and MTR reports are available for project acceptance.
