How to distinguish CS seamless pipe from ssaw steel pipe?

Different definitions

CS seamless pipe is a long strip of steel with a hollow section. Pipelines are widely used to transport fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, steel pipes have the same flexural and torsional strength and are lighter in weight. It is an economical steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames and steel scaffolding for building construction.

SSAW steel pipe is a spiral seam steel pipe welded by automatic double-wire double-sided submerged arc welding process, which is made of strip steel coil as raw material, often extruded at high temperature. Sawing the steel pipe will send the steel strip into the welded pipe device. After the strip is rolled by multiple rolls, it is gradually rolled up to form a round tube blank with an opening gap. 3mm, and make both ends of the weld flush.

The production process is different

SSAW steel pipe is a large-diameter steel pipe formed by continuous welding of steel strips or steel plates after bending and shaping;

CS seamless pipe is a pipe processed from steel billets through heating, perforation and other processes, and the whole body has no gaps.

Different characteristics

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

Different uses

SSAW steel pipe is mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. It 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 structures: for piling pipes, for bridges; suitable for docks, roads, building structures, etc.

Different prices

Compared with cs seamless pipe, ssaw steel pipe is more economical in price.
