Is the general spiral steel pipe made of Q235

Commonly used spiral steel pipes do not use Q235 material. The commonly used spiral steel pipe materials are: Q235A, Q235B, Q345, L245, L290, X42, X52, X60, X70, X80, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb materials.

Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle) and then welding the pipe seam. , which can produce large-diameter steel pipes from narrower strips.

Spiral steel pipes are mainly used in water supply engineering, the petrochemical industry, the chemical industry, the electric power industry, agricultural irrigation, and urban construction. They are 20 key products developed by our country. For liquid transportation: water supply, drainage, sewage treatment engineering, mud transportation, ocean water transportation. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: such as piling pipes and bridges; pipes for harbors, roads, building structures, marine piling pipes, etc.
