Hot Rolled Welded Steel Square Pipe And Rectangular Tube

1.The surface of the rectangular square pipe is hot-dip or galvanized welded steel pipe. Hot-dip galvanizing can be improved The steel pipe is corrosion-resistant and prolongs its service life. Galvanized square pipes are widely used, in addition to water,General low-pressure fluid pipelines such as natural gas and oil are also used in the petroleum industry, especially offshore oil wells and pipelines.
2.A rectangular pipe is a hollow square cross-section lightweight, thin-walled steel pipe, also known as a steel refrigeration bending profile. It is a square cross-sectional shape and size steel made of Q235 hot-rolled or cold-rolled strip or coil as the base metal, formed by cold bending, and then welded by high frequency.
3.Rectangular steel pipes have high tensile strength and large bearing capacity. Smooth inner and outer surfaces with precise dimensions. Suitable for fields such as high-voltage equipment, petroleum geology, shipbuilding, etc.
