Galvanized square pipe is a hollow square section steel pipe with a square section shape and size made of hot-rolled or cold-rolled galvanized strip steel or galvanized coil as a blank, cold-bent and formed by high-frequency welding. Or a galvanized rectangular tube made of cold-formed hollow steel pipe prepared in advance and then processed by hot-dip galvanizing. Galvanized square pipes are divided into hot-dip galvanized square pipes and cold-galvanized square pipes from the production process. It is precisely because the processing of these two galvanized square tubes is different that they have many different physical and chemical properties. In general, they have many differences in strength, toughness and mechanical properties.

Advantages

Applications
Galvanized steel pipes have a wide range of uses. In addition to being used as pipelines for low-pressure fluids such as water, gas, and oil, it is also used in the petroleum industry, especially oil well pipelines, oil pipes and petroleum heaters in offshore oil fields, and used in chemical coking equipment. Condensation cooler, coal distillation wash oil exchanger pipeline, as well as mine pipe piles, mine tunnel support frame pipelines,Urban/civilian construction pipes, mechanical structure pipes, agricultural equipment pipes, water and gas pipes, greenhouse pipes, scaffolding pipes, building materials pipes, furniture pipes, low pressure fluid pipes, oil pipes, etc. Also, galvanized steel pipes are widely used in construction, machinery, coal mining, chemical industry, electric power, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, exploration machinery, greenhouse construction and other manufacturing industries.
