Welded pipe production line processing and production of steel pipe in the thickness of the size of the scope of a higher coordination capacity

Welded pipe production lineProcessing and manufacturing steel pipes have higher coordination ability in the size and specification of outer diameter and thickness, and can produce both large quantities of goods and small quantities of goods. It can not only produce small-diameter high-toughness thick-walled steel pipes, but also produce small-diameter and large-thickness steel pipes. Especially in the production of high-grade thick-walled steel pipes, especially medium-diameter small-thick-walled steel pipes, it has advantages that other processing technologies do not have.
The welded pipe production line can meet more requirements of customers at the level of steel pipe specifications and models. Low investment, but the production efficiency is relatively low, the general annual output is 10~250000 t.
The straight seam high frequency welded pipe (ERW) of the welded pipe production line is produced by heating and melting the edge of the pipe material by using the pulse current of the high frequency current and the proximity effect after the hot rolled plate is formed by the forming machine, and the working pressure electric welding is carried out under the influence of the squeezing roller.
Welded steel pipes, also known as welded pipes, are made of thick steel plates or hot-rolled strip steel through electric welding after rolling and forming. Welded steel pipe production and processing technology is simple, production efficiency, types and sizes, less machinery and equipment, but the general compressive strength is less than seamless splicing steel pipe.
According to the classification of production methods: processing technology classification-arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
Welded pipe production line of straight seam welded pipe production process is simple, production efficiency, low cost, rapid development trend. The strength of spiral welded pipe is generally higher than that of straight welded pipe. Narrow blank can be used to produce welded pipe with larger pipe diameter, and different types of welded pipe can also be produced with blank material with the same width.
However, compared with the same length straight seam pipe, the weld length is increased by 30~100%, and the production rate is relatively low.
The blank material used for welding steel pipe is thick steel plate or hot rolled strip steel, which is divided into furnace welded pipe, arc welding (resistance welding machine) pipe and automatic arc welded pipe according to different welding methods. According to the difference of welding form, it is divided into two kinds: straight seam welded pipe and spiral welded pipe. Because the top shape is divided into annular welded pipe and special-shaped (square, flat, etc.) welded pipe.
