20*20 Galvanized Steel Pipe Round API J55
Production Description

Fire-fighting engineering: The current fire-fighting water supply pipes are basically galvanized pipes, and a layer of paint is applied to the outer layer of the galvanized pipes, so that everyone can see the red fire-fighting pipes, which areactually only plated. Zinc tube is formed by processing.Steel structure and welding engineering: Now many scaffolding workshops outside, the old workshops were built with welded steel pipes, but the welded steel pipes are prone to rust. In order to prevent rust, a layer of paint must be applied. In order to solve this problem, Nowadays, many new steel structure projects directly use galvanized pipes, which can save man-hours and can last longer. Agriculture: mainly used to build warm greenhouses, flower sheds, and pillars for flowers and melons.

Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned, and the latter is also advocated by the state to be used temporarily. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. Four ministries and commissions including the Ministry of Construction of China also issued a document clarifying that galvanized pipes have been banned as water supply pipes since 2000. Galvanized pipes are rarely used for cold water pipes in newly built communities, and galvanized pipes are used for hot water pipes in some communities. Hot-dip galvanized steel pipes are widely used in fire fighting, electric power and highway.
