Cylinder pipe are mainly applied in hydraulic driving equipment (including hydraulic and pneumatic steel cylinder, hydraulic support, oil-well pumping barrel, and etc.) used for the manufacturing of vehicle, engineering machinery, lifting and transportation machinery and other machinery.
Cold drawn cylinder pipes are manufactured by pulling a solid cylindrical bar through a die to reduce its diameter and achieve the desired dimensions.

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
