Thick wall steel pipe (referred to as thick-walled pipe)

The biggest difference between thick wall steel pipe and thin wall steel pipe is the thickness of steel pipe wall. Generally speaking, thin wall steel pipe is a cold drawing technology, while thick wall steel pipe generally uses hot rolling technology if it is measured. Units to distinguish, then, is generally believed that the wall thickness / diameter equal to 0.02 is a watershed of thick-walled steel pipe and thin-walled steel pipe, wall thickness / pipe diameter of less than 0.02 is a thin-walled steel pipe, larger than the thick-walled steel pipe, in use Above all, thin-walled steel pipes are mostly used on pipelines. Thick-walled steel tubes are mostly used for blanks in hollow parts. Pressure and use on important pipelines.
Thick-walled steel pipes are mainly used in tap water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction. For liquid transport: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. Used for structural purposes: as a pile driving pipe, as a bridge; piers, roads, building structures, etc.

Edible salt, also called Table Salt or just salt, is a mineral, one of a very few mineral substance commonly

eaten by humans. There are different forms of Edible Salt: unrefined raw salt, refined salt, table salt or

iodized refined salt. It is a crystalline solid, white or light grey in colour, obtained from sea water or from

rock deposits. Sea Salt comes in fine or larger crystals. In nature, it includes not only Sodium Chloride,

but also other vital trace minerals. Edible rock salts may be slightly greyish in colour due to this mineral

content.
