Product Introduction

Large-diameter spiral steel pipes generally refer to spiral steel pipes with a diameter greater than 1 meter. Spiral steel pipes are made of steel strips that are bent and then welded.

The manufacturing process of large-diameter ssaw pipe is to roll a steel strip of a certain length through rollers and then weld it into a pipe of a certain length. Compared with traditional steel pipes, it is not only more mature in technology, but also can produce larger diameter pipes, which can reduce the number of pipes and reduce project costs while ensuring quality.

In addition, the corrosion resistance of large-diameter spiral welded pipe is also one of its excellent properties. During the manufacturing process, different types of anti-corrosion coatings can be used to greatly extend the service life of the pipeline. At the same time, during the use of pipelines, widely used surface anti-corrosion materials can also ensure their long-term corrosion resistance, providing guarantee for the reliable operation of the project.

Commonly used materials are: Q235A, Q235B.Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb. Q345 L245 L290 X42 X46 X70 X80.

Cutting method of large diameter spiral steel pipe:

Prepare the corresponding tools, such as cutting machines, grinders, hand hammers, wire brushes, etc. Polish the surface of the spiral steel pipe to remove rust, oil and other impurities to ensure a smooth cutting surface. Use chalk or paint to mark the cutting lines on the spiral steel pipe, making sure the markings are clear and accurate. Place the spiral steel pipe on the cutting machine, adjust the position and angle of the cutting machine, and then cut. Maintain stability when cutting to avoid cutting deviations. Use a grinder to smooth the cutting surface and remove burrs and edges to ensure cutting quality. Check whether the cutting surface is smooth and whether there are cracks, burrs and other defects. If there are defects, they need to be repaired.
