The difference between thin-walled spiral steel tube and thick-walled spiral steel tube

Keywords :spiral steel tube, thin walled spiral steel tube, thick walled spiral steel tube        Update : 2024-11-01        View(s) : 171

First, the concept of a thin-walled spiral tube: the strip steel is fed into the welded pipe unit, and after multiple rollers rolling, the strip steel is gradually rolled up to form a round tube blank with an open gap. The pressing amount of the extrusion roller is adjusted to control the weld gap t...

The formation process and characteristics of tempered troostite in steel pipes

Keywords :steel pipe tempered troostite, steel pipe process, steel pipe characteristics        Update : 2024-10-30        View(s) : 154

Troustite can be divided into quenched troostite and tempered troostite. For example, in the normal martensite quenching process, quenched troostite is formed in the troostite transformation zone due to the slow cooling rate. Another case is to first quench to obtain quenched martensite, and then te...
