Product introduction
1. Product Overview
76-660mm HFW Custom Wall Thickness Non-standard Welded Tube is a personalized customized high-frequency welded steel pipe developed for special engineering projects that cannot be met by standard SCH/STD pipe specifications. Breaking the limitation of conventional fixed wall thickness and fixed size welded pipes, this product supports full-range non-standard customization of outer diameter, wall thickness and pipe length within 76mm-660mm OD range, solving the size mismatch problem of pipeline construction in special industrial, municipal, mechanical and infrastructure projects.
Adopting advanced HFW high-frequency welding technology and precision rolling forming process, our custom non-standard welded pipes strictly control dimensional tolerance and weld quality. All customized sizes undergo independent process debugging and quality testing to ensure mechanical performance, pressure resistance and structural stability fully meet custom project design requirements. It is the most reliable customized pipe solution for special pipeline engineering with non-standard size parameters at home and abroad.

4. Core Custom Product Performance
4.1 Personalized Structural Stability
For non-standard thin-wall and thick-wall customized pipes, we adjust rolling compression ratio and welding parameters in real time to ensure uniform pipe body structure and no deformation. Custom thick-wall pipes have high pressure-bearing capacity, while custom thin-wall pipes maintain structural rigidity, fully adapting to special structural and pressure-bearing requirements of non-standard projects.
4.2 Zero-Defect Custom Weld Quality
Aiming at non-standard size characteristics, adopt targeted high-frequency welding process and online heat treatment technology. The weld strength is consistent with the base metal, with no crack, trachoma or leakage risk. 100% full-length ultrasonic inspection ensures the stability of custom weld quality for special pipeline working conditions.
4.3 High Installation Matching Accuracy
Strict one-to-one size calibration for non-standard custom dimensions, precise control of roundness, straightness and end flatness. Effectively solve the problem of difficult assembly and poor sealing of special-size pipes on site, greatly improving the installation efficiency and engineering qualification rate of non-standard projects.
4.4 Environmentally Adaptable Custom Performance
According to customer's use environment (high temperature, low temperature, humid, corrosive, outdoor buried), customize matching steel grades and surface anti-corrosion processes. Realize personalized anti-rust, anti-corrosion and temperature-resistant performance, ensuring long-term stable operation of non-standard pipelines in special environments.
4.5 Project Cost Optimization
Precise customization according to project design parameters eliminates the need for forced replacement of standard pipes. Avoid structural performance redundancy or insufficient bearing capacity caused by size mismatch, effectively saving project procurement and construction costs for special pipeline engineering.
5. Strict Customized Quality Inspection System
All non-standard custom HFW welded pipes adopt customized inspection standards based on customer project requirements, abandoning single standard pipe detection mode to ensure full compliance with project acceptance specifications:
Raw material performance test matching custom working conditions
One-to-one full-dimensional size detection for non-standard parameters
Customized hydrostatic pressure test (simulate actual project working pressure)
Weld bending, flattening and impact performance test
100% online ultrasonic weld non-destructive flaw detection
