Thick Wall Seamless Steel Pipe

 Thick Wall Steel Pipe And Its Application

 

The steel pipe with outer diameter to wall thickness ratio is less than 20 is called thick-walled steel pipe. Mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industry, boiler pipes, bearing pipes and high-precision structural pipes for automobiles, tractors, and aviation.

 

The biggest difference between thick wall steel pipe and thin wall steel pipe is the wall thickness. Generally speaking, thin wall steel pipes are cold drawn/rolled and thick-walled steel pipes are hot-rolled. If it is distinguished by measurement units, it is generally believed that thickness/ diameter equal to 0.02 is the demarcation point between thick wall steel pipes and thin wall steel pipes, thin wall steel pipes are less than 0.02 and thick wall steel pipes are more than 0.02. In terms of usage, thin-walled steel pipes are mostly used for pipelines and thick wall steel pipes are mostly used in blanks of hollow parts, pressure-bearing and important pipes.

 

Thick wall steel pipes are mainly used in water supply engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, urban construction. For liquid transportation: water supply, drainage. For gas transportation: coal gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes, bridges, wharves, roads, building structures, etc.
