Spiral Steel Pipe

Since steel has good physical, chemical and mechanical properties, it can be used for rolling, piercing, drawing, punching, etc. So, spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are more widely applied than cast iron. Forging cast iron is used for producing cast iron parts. About 90% cast iron is smelt and made into steel in steelmaking to meet demands of all walks of life.

Product Details


Spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are made of low-carbon environment-friendly carbon steel or low-alloy steel chains stacked up into the pipe blank according to the vortex figure and the subsequent electric welding of weld joints. They can be made of narrow hot rolled strip steel. Large-caliber seamless steel pipe. The spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are the spiral submerged arc weld pipes. They have been widely applied to infrastructure of various natural gas pipes. Their specifications are described with diameter and wall thickness. Spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are made with one-side weld or double-side weld. It shall be ensured that spiral weld pipes receive the pressure test, and the compressive strength and cold-drawing performance of weld shall meet requirements.
Spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are mainly made of the following two types of materials: steel and iron. Iron is classified into cast iron and industrial pure iron. Industrial pure iron is of good ductility and good weldability, but its strength and hardness are relatively poor. In addition to application in the electric industry, it has not been widely applied in other industrial fields, so most iron in daily life refers to cast iron. From the perspective of chemical composition, both steel and cast iron fall to iron-carbon alloy and contain Si, Mn and P, but the content of such elements is different. The carbon content of 2% is the cut-off point of steel and cast iron. Usually, iron-carbon alloy with the carbon content of 2%-4.5% is called cast iron, while iron-carbon alloy with the carbon content of 0.02%-2.0% is called steel, and the iron-carbon alloy with the carbon content less than 0.02% is called pure iron.
Since steel has good physical, chemical and mechanical properties, it can be used for rolling, piercing, drawing, punching, etc. So, spiral weld pipes sold by Zhongyuan Pipeline Manufacturing Co., Ltd. are more widely applied than cast iron. Forging cast iron is used for producing cast iron parts. About 90% cast iron is smelt and made into steel in steelmaking to meet demands of all walks of life.
