What is the practical difference between straight seam steel pipe and seamless pipe?

The difference between straight seam steel pipe and seamless pipe in the production process*** is that straight seam steel pipe is made by rolling the plate open flat and then welded by resistance welding, or submerged arc welding. There is a longitudinal weld seam. Seamless steel pipe is made by hot rolling round steel or by cold drawing process. As the name implies, seamless steel pipe has no welded seam.

Polyurethane insulation steel pipe has good mechanical properties and thermal insulation properties

How is the corrosion resistant bend made?

Many people doubt the corrosion resistance of 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe, only if you understand the production technology of 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe, you will understand that 3pe elbow anticorrosive steel pipe and 2pe elbow anticorrosive steel pipe are as good as the general anticorrosive steel pipe. 3pe elbow anticorrosive steel pipe looks messy, the reason is that the anticorrosive of these two are Ended in a specific equipment. And the equipment is unable to meet the construction of the elbow. Generally speaking, only straight pipes can end the construction on the equipment. Regarding the 3PE or perhaps 2PE anti-corrosion of bends, the general solution is as follows:

5 kinds of coloring methods of anti-corrosion steel pipes are introduced

Anti-corrosion steel pipe surface mirror bright treatment method: according to the complexity of anti-corrosion steel pipe products and user requirements of different situations can be used respectively mechanical polishing, chemical polishing, electrochemical polishing and other methods to achieve a mirror gloss. Anti-corrosion steel pipe coloring methods are as follows:

How to identify the quality of polyurethane insulation steel pipe?
