How to distinguish inferior spiral steel pipe?
Spiral steel pipes, also known as spiral welded pipes, are manufactured by rolling strips of low-carbon structural steel or low-alloy structural steel at an angle to form a continuous tube blank. The edges of the tube are then welded together along the spiral seam. This production method allows the creation of large-diameter steel pipes using relatively narrow steel strips, making SSAW pipes highly versatile for specific applications like water pipelines, piling, and structural supports.

Introduction to insulation spiral steel pipe
Insulated Spiral Steel Pipe refers to spiral steel pipes (SSAW pipes) that are specially treated for thermal insulation. The most common method of heat preservation is polyurethane insulation, where the steel pipe is coated with a layer of polyethylene or steel, with the thickness tailored to customer needs. Foam is injected between the pipe and its outer jacket, and the foam thickness can also be adjusted based on customer specifications. Insulated spiral steel pipes can be installed either overhead or underground. These pipes are widely used in the transportation of liquids and gases, as well as in chemical, petroleum, and municipal engineering projects, including central heating networks, central air-conditioning systems, and chemical pipe insulation.
