Galvanized steel pipe Galvanized steel pipe
Galvanized steel pipe
2026-10-20
Hot dip galvanized steel pipe starts as ERW welded or seamless carbon steel tube. It is cleaned, then dipped in molten zinc, so a metallurgically bonded zinc coating forms on the surface — on hot dip material the bore is coated as well as the outside.

Galvanized Square Pipe
2026-04-30
Galvanized square steel pipe is a welded steel pipe with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and prolong the service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipes in the petroleum industry, especially in offshore oil fields, and oil heaters and condensers in chemical coking equipment. Pipes for coolers, coal distillation washing oil exchangers, and pipes for trestle piles and supporting frames of mine tunnels, etc.
Galvanized steel fire sprinkler pipe
Galvanized steel fire sprinkler pipes, often referred to as GI (Galvanized Iron) fire pipes, are carbon steel pipes coated with a zinc layer to enhance corrosion resistance, designed specifically for fire protection systems like wet, dry, preaction, and deluge sprinkler systems. ASTM A795, a key standard for these pipes, specifies both black and hot-dip galvanized welded (ERW) and seamless steel pipes for fire fighting applications, available in Grades A and B, with Grade B being more common due to its mandatory post-weld heat treatment (minimum 1000°F or 540°C). The galvanization process involves dipping the steel pipe in molten zinc, creating a protective coating of at least 1.5 oz/ft² (0.46 kg/m²), which shields the pipe from rust in moist environments, per ASTM A795 requirements.
