Different definitions

CS seamless pipe is a long strip of steel with a hollow section. A large number of pipelines are used for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipe has the same bending and torsional strength, and is lighter in weight. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, Bicycle racks and steel scaffolding used in building construction, etc.
SSAW steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. The ssaw steel pipe feeds the strip into the welded pipe unit. After being rolled by multiple rollers, the strip is gradually rolled up to form a circular tube blank with an opening gap. 3mm, and make both ends of the welding joint flush.

Different production processes

SSAW steel pipe is a steel pipe with a large diameter formed by continuous welding of steel strip or steel plate after bending and shaping;
The cs seamless pipe is a pipe processed by heating, perforating and other processes of the billet, and there is no gap in the whole body.

Different characteristics

The characteristics of the ssaw steel pipe: the production process of the straight seam welded pipe is simple, the production efficiency is high, the cost is low, and the development is fast. The strength of the ssaw steel pipe is generally higher than that of the straight seam welded pipe. However, compared with the same length of straight seam pipe, the length of the weld is increased by 30~100%, and the production speed is lower. Therefore, most of the welded pipes with smaller diameters use straight seam welding, and most of the welded pipes with large diameters use spiral welding.

Different uses

SSAW steel pipe is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction, and is one of the twenty key products developed in my country.
For liquid transportation: water supply, drainage;
For gas transportation: gas, steam, liquefied petroleum gas;
For structure: for piling pipe, for bridge; for wharf, road, building structure, etc.

Different prices

Compared with cs seamless pipes, the price of ssaw steel pipes is more economical.
