Insulation steel pipe is an important factor affecting energy saving, and the development and application of insulation steel pipe have received more and more attention from countries all over the world.

The thickness of the insulation layer of polyurethane insulation steel pipe is directly related to the insulation effect. The thicker the insulation layer, the better the insulation material and the better the quality.

Some notes on the transportation, loading and unloading and storage of spiral welded pipes for steel protective cylinders.

The spiral steel pipe adopts a special welding process without any errors and defects, which can ensure the qualification of the spiral steel pipe and the quality is well guaranteed.

The finished spiral welded pipe is water-cooled and rolled off the production line, but after high temperature heating, the temperature of the spiral welded pipe after water cooling is still quite high.

There are several methods for cutting fluid seamless pipes, including shearing, breaking, sawing, flame cutting and anode cutting.
