Key points for the installation of galvanized pipes
1、Installation Guidelines for Hainan Galvanized Pipes
Inspection Before Installation
Check pipes and fittings to ensure they are free from surface defects, meet dimensional requirements, and have intact zinc coating.
Repair or replace any damaged galvanized pipes to avoid compromising performance.
2、Threaded Connections
Ensure thread quality—smooth and burr-free.
Use appropriate sealing materials (e.g., PTFE tape) to prevent leaks.
Avoid over-tightening, which may damage the zinc coating.
3、Welded Connections
After welding, apply zinc-rich repair coating to the weld seam and heat-affected zone to restore corrosion protection.
Note:Welding vaporizes the zinc layer, leaving areas vulnerable to rust.
4、Handling & Damage Prevention
Avoid mechanical damage (scratches, impacts) during installation.
Promptly repair any zinc layer damage using zinc-rich paint or approved methods.http://www.hnftsteels.com
