Product introduction
Product Overview
We are a professional manufacturer specializing in custom HFW high-frequency straight welded carbon steel tubes with outer diameters ranging from 76mm to 660mm. Adopting advanced high-frequency induction welding technology, our custom carbon steel welded tubes feature uniform weld structure, high structural stability, precise dimensional accuracy and excellent mechanical performance. Different from standard fixed-size steel pipes, this series supports full-customized specifications to meet diverse non-standard and project-specific pipeline demands.
All custom HFW carbon steel tubes are produced with premium low-carbon steel raw materials, strictly following international manufacturing and testing standards. We support customized outer diameter, wall thickness, pipe length, surface treatment, pipe end processing and mechanical property requirements. Widely applicable for structural engineering, water conveyance, mechanical manufacturing, municipal construction and industrial pipeline projects, our custom steel tubes provide one-stop personalized manufacturing solutions for global distributors, engineering contractors and factory clients.
Production Process
Custom Raw Material Preparation: Select qualified carbon steel coils according to customer's technical requirements, control chemical composition and mechanical indicators precisely to match custom project standards.
Precision Slitting & Forming: Slit steel coils into customized strip width, and adopt multi-pass cold rolling forming process to ensure consistent roundness and structural uniformity of custom tube blanks.
HFW High-Frequency Welding: Apply high-frequency induction welding technology with adjustable welding parameters according to tube specifications. The narrow heat-affected zone ensures strong, tight and defect-free welding seams for custom tubes.
Full Weld Bead Trimming: Remove internal and external welding beads thoroughly, polish the tube wall smoothly to eliminate stress concentration and meet high-precision custom pipeline requirements.
Custom Sizing & Straightening: Adjust sizing and straightening equipment parameters targeting custom dimensions, strictly control OD, wall thickness and straightness tolerance within customer-specified ranges.
NDT & Hydrostatic Testing: Conduct 100% eddy current non-destructive flaw detection and hydrostatic pressure test on finished tubes to ensure welding quality and pressure resistance meet custom technical standards.
Custom Fixed-Length Cutting: Cut tubes into arbitrary fixed lengths as required, support irregular length customization to reduce on-site secondary processing and material waste.
Personalized Surface & End Treatment: Provide custom processing including black uncoated finish, anti-rust oil coating, hot-dip galvanizing, pipe end chamfering, grooving and threading.
Targeted Sampling Inspection: Conduct customized mechanical and chemical tests based on customer order standards, provide exclusive inspection reports for each custom batch.
