Product introduction
Product Title
HFW Galvanized Thin Wall Pipe 76~660mm Small Household Water Project Tube / HFW Welded Hot-dip Galvanized Thin Wall Steel Pipe for Residential Domestic Water Works
Brief Introduction
HFW Galvanized Thin Wall Pipe is high-frequency welded thin-wall steel pipe with hot-dip galvanized surface, specially manufactured for small household water supply projects. Outer diameter ranges from 76mm to 660mm.
This thin wall HFW pipe adopts advanced HFW high-frequency resistance welding process, followed by hot-dip galvanizing treatment to form a uniform zinc coating on inner and outer surfaces. The zinc layer provides excellent rust and corrosion resistance, effectively protecting the pipe from oxidation in indoor and mild outdoor environments. With light weight, smooth surface, stable weld quality and easy cutting and threading, it is ideal for small residential water projects. Online normalization eliminates welding residual stress to ensure weld integrity. We can provide custom fixed-length pre-cutting, deburring and pipe end protection. It is widely used for community household water supply, residential building branch water pipes, small villa water distribution networks and domestic water renovation projects. Hebei Huayang controls zinc coating thickness strictly to guarantee long service life for household water delivery systems.

Production Process & Pipeline Performance
Thin Wall Grade Steel Coil Raw Material High-quality low carbon steel coil is selected for thin wall pipe production. Raw materials are checked for chemical composition and ductility to ensure good forming performance during rolling and welding, avoiding cracking during galvanizing and later threading processing.
HFW High Frequency Forming & Welding Multi-pass continuous precision rolling forms thin wall round tube. High-frequency welding without filler metal. Online inner and outer scarfing removes weld flash, ensuring smooth pipe surface for subsequent galvanizing. The thin wall tube maintains good roundness and uniform wall thickness.
Online Weld Normalization Heat Treatment Weld seam normalization relieves welding residual stress, balances mechanical performance between weld and base metal. It prevents weld cracking in the hot-dip galvanizing high-temperature process and improves the stability of thin wall pipe for long-term water delivery.
Hot-Dip Galvanizing Anti-Corrosion Treatment After pipe cleaning and pre-treatment, the pipe is immersed in molten zinc. A tight zinc coating is formed on both inner and outer pipe surfaces. The zinc layer isolates air and moisture, providing reliable anti-rust protection for household water pipelines. Zinc thickness can be adjusted according to project requirements.
Finished Pipe Inspection & Preprocessing 100% online ultrasonic weld inspection and hydrostatic pressure test. Zinc coating thickness test, surface visual inspection and dimensional checking are performed batch by batch. We support fixed-length cutting, deburring and threading for on-site installation of household water projects.
Key Advantages
✅ Hot-Dip Galvanized Anti-Corrosion: Uniform zinc coating inside and outside, effectively preventing rust for household water pipelines ✅ Light Thin Wall Design: Lower material cost, easy transportation, cutting and manual installation for residential projects ✅ Smooth Inner Wall: Low water flow resistance, less scaling, keeps household water clean and reduces maintenance ✅ Stable Weld Performance: Stress relieved weld seam, no leakage risk under normal household water pressure ✅ Flexible On-site Processing: Support threading, pre-cutting and end finishing to fit small household water project construction ✅ Strict Zinc Layer Control: Stable galvanizing quality, long service life for indoor residential water supply
