High Production Efficiency Of Welded Steel Pipe
Oct 18, 2017



Welded steel pipe is also known as welded pipe, is made of steel plate or steel after the forming of welded steel pipe. Welded steel pipe production process simple, high production efficiency, variety specifications, equipment, but the general strength of less than seamless steel tube. Since the 1930s, with the rapid development of high quality strip rolling production and the progress of welding and inspection technology, Welded Steel Pipes the weld quality has been increasing, the variety specifications of welded steel pipe are increasing, and more and more fields have replaced the seamless steel tube. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe.

Welded steel pipe used in the billet is steel plate or strip, because of its different welding process and divided into furnace welded pipe, welding (resistance welding) pipe and automatic arc welded pipe. Welded Steel Pipes Because of its different types of welding is divided into straight seam welded pipe and spiral welded pipe two. Because of its end shape is divided into circular welded pipe and shaped (square, flat, etc.) welded pipe.

The variety specification of welded steel pipe is increasing, and the seamless steel tube is replaced in more and more fields. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe. Straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe, which can produce pipe with larger diameter with narrower billet, and can produce pipe with different diameters with same width. But compared with the same length of straight seam tube, the weld length increases $number and the production speed is lower. Therefore, Welded Steel Pipes the smaller-caliber welded pipe mostly adopts straight seam welding, and the large diameter welded pipe is mostly spiral welded.

1. Low-pressure fluid transport welded steel pipe (gb/t3092-1993) also known as the general welded pipe, commonly known as clarinet. is used for conveying water, gas, air, oil and heating steam and other general low pressure fluid and other uses of welded steel pipe. The pipe wall thickness is divided into ordinary steel pipe and thickened steel pipe, and the nozzle is divided into non threaded steel pipe (light tube) and threaded steel pipe. The specification of the steel pipe is indicated by the nominal caliber (mm), Welded Steel Pipes and the nominal caliber is the approximate value of the inner diameter. Commonly used in inches, such as 11/2. In addition to the direct use of welded steel tubes for conveying fluids, low pressure fluid transport is also used as the original tube of galvanized welded steel tubes for low pressure fluid transport.

2. Low-pressure fluid transport galvanized welded steel pipe ($literal) also known as galvanized welded steel pipe, commonly known as white tube. is used for conveying water, gas, air, oil and heating steam, warm water and other general low pressure fluid or other uses of hot-dip galvanized welding (furnace welding or welding) steel pipe. Welded Steel Pipes The thickness of steel pipe wall is divided into ordinary galvanized steel pipe and thickened galvanized steel pipe, and the nozzle is divided into non threaded galvanized steel pipe and galvanized steel pipe with threaded thread. The specification of the steel pipe is indicated by the nominal caliber (mm), and the nominal caliber is the approximate value of the inner diameter.
