Q235B Welded Spiral Pipe

Q235B spiral steel pipe also has excellent elongation, toughness and castability, and the weld length is increased, so the production speed is lower. Therefore, straight seam welding is mostly used for smaller diameter welded pipes, while spiral welding is mostly used for large diameter welded pipes.

Product Introduction

Q235B spiral steel pipe is a kind of steel pipe with spiral outer surface, which has the following characteristics: High strength: Q235B is a low-alloy high-strength structural steel with high strength and bearing capacity, and can withstand various conditions such as high pressure, heavy load and high temperature. Corrosion resistance: The outer surface of Q235B spiral steel pipe has been specially treated, which has good corrosion resistance and can resist the corrosion of various chemicals, thus reducing the damage and maintenance of the pipeline. Easy connection: The connection modes of spiral steel pipes are simple and varied, such as welding, flange connection, socket connection, etc., which are convenient and quick, and can greatly shorten the construction period. Economy: Under the same conditions, Q235B spiral steel pipe is cheaper than other metal pipes, and it is an economical and practical pipe material. The application fields of Q235B spiral steel pipe include water supply and drainage engineering, sewage treatment, gas transportation, petrochemical industry and thermal transportation. The production process mainly includes cutting and curling of steel plate, forming and welding of tube blank, heat treatment and straightening, surface treatment and detection.
