DN900 spiral steel pipe is a common type of steel pipe with an inner diameter of 900 mm. This steel pipe is made of high-quality steel and produced through a spiral welding process. DN900 spiral steel pipe has excellent bearing capacity, corrosion resistance, ductility and other properties, and is widely used in water supply and drainage, oil, natural gas, electricity and other fields.
DN900 spiral steel pipe specifications and performance characteristics
Specifications: The inner diameter of DN900 spiral steel pipe is 900 mm, and the wall thickness can be selected in different specifications according to actual needs, such as 6mm, 8mm, 10mm, etc.
Material: Commonly used materials include Q235, Q345, 16Mn, X60, X70, etc., which have good mechanical properties and corrosion resistance.
Welding process: Double-sided submerged arc welding and spiral welding processes are used. The welding seam is smooth, no bubbles, no cracks, and has good sealing performance.
Surface treatment: Anti-corrosion and anti-rust treatment can be carried out according to needs, such as 3PE, epoxy coal pitch and other anti-corrosion layers to extend the service life of the steel pipe.
Performance characteristics: DN900 spiral steel pipe has the advantages of high bearing capacity, corrosion resistance, ductility, earthquake resistance, etc., and can meet the requirements of different engineering environments.
