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.

How is the corrosion resistant bend made?

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:

What is a welded pipe? Definition of piping

What is a welded pipe? Definition of piping

Welded piping is a device for conveying gases, liquids or fluids with solid particles by coupling pipes, pipe couplings (fittings) and valves, etc. Usually, fluid is pressurized by blowers, compressors, pumps and boilers, etc., and flows from the high pressure of the pipe to the low pressure, or it can be transported by the fluid's own pressure or gravity. Pipelines are used in a wide range of applications, mainly in water supply, drainage, heating, gas supply, long-distance transportation of oil and gas, agricultural irrigation, hydraulic engineering and various industrial installations.
