Thick wall steel pipe is also called as thick-walled tubes or thick walled pipe or heavy wall pipes. Thick wall thickness steel pipe means the ratio of the outer diameter and wall thickness is less than 20. The main application of thick wall seamless steel pipe is as boiler steel pipe, making high precision components of cars, tractors and space industry, making bearings and as geological drilling pipe.

Large diameter thick wall steel pipe is steel pipe diameter with large diameter and wall thickness is less than 20 steel pipe. Thick wall steel pipe can be used as geological drill pipe is mainly used for oil, oil chemical industry with the cracking of pipe, boiler tube, bearing and automobile, tractor and aviation with high precision tube structure etc.
Large diameter thick wall steel pipe has the biggest difference between thin-walled steel tube in the steel tube wall thickness. Generally speaking thin-walled steel pipe cold drawing technology, and the thick wall steel pipe generally use hot rolling technology. If unit of measure is used to distinguish. So it is generally believed that wall thickness/diameter is equal to 0.05 is the watershed thick-walled steel pipe with large diameter and thin wall steel tube. Wall thickness is thin wall steel tube/pipe diameter less than 0.05 is greater than thick wall steel pipe. On purpose thin-walled steel tube used in pipeline and large diameter thick wall steel pipe used in billet of hollow parts. Thick wall steel tube is mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation and urban construction. And large diameter thick wall steel pipe can be used in liquid transportation, water supply and drainage and transporting gas, steam, liquefied petroleum gas. And also used in piling pipe, bridge, Dock, road, and building structural. Our large diameter thick wall steel pipe is with good price, low MOQ and high quality.
