What is the production process of the welded pipe?
Mar 30, 2017


What is the production process of straight seam welded pipe? Straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of the spiral welded pipe is generally higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced with the narrow billet. The pipe with different diameter can also be produced with the same width. However, compared with the same length of the straight pipe, the weld length increased by 30 to 100%, and the production rate is low.

Therefore, the smaller diameter of the pipe are mostly used straight seam welding, large diameter welded pipe are mostly used spiral welding.

         1. Low-pressure fluid delivery with welded steel pipe (GB / T3092-1993), also known as the general pipe, commonly known as black tube. Is a welded steel pipe for the transport of water, gas, air, oil and heating steam, and other generally lower pressure fluids and other uses. Steel pipe wall thickness is divided into ordinary steel pipe and thickened pipe; take the end of the form is divided into non-threaded steel pipe (light pipe) and threaded steel pipe. The specifications of the steel pipe are denoted by nominal caliber (mm), and the nominal caliber is the approximate value of the inner diameter. Commonly used in inches, said low-pressure fluid delivery welded pipe in addition to direct use for the transport of fluid, but also a large number of low-pressure fluid for the use of galvanized welded steel pipe of the original pipe.

         2. Low-pressure fluid transmission with galvanized welded steel pipe (GB / T3091-1993) also known as galvanized welded steel pipe, commonly known as white tube. It is a hot dip galvanized (welded or welded) steel pipe used to transport water, gas, air oil and heating steam, warm water and other generally lower pressure fluids or other uses. Steel pipe wall thickness is divided into ordinary galvanized steel pipe and thick galvanized steel pipe; take the end of the form is divided into non-threaded galvanized steel pipe and threaded galvanized steel pipe.
