Bearing Pipes
Pipes designed for bearing loads, offering high strength and durability.
Cold drawn cylinder pipes are precision pipes that have been manufactured through a cold drawing process.
This method involves pulling a hollow tube through a die to reduce its diameter and wall thickness, which results in improved mechanical properties and surface finish. These pipes are widely used in various industries due to their high strength, precision, and excellent surface quality.
Cold drawn cylinder pipes are manufactured by pulling a solid cylindrical bar through a die to reduce its diameter and achieve the desired dimensions.

Cold drawn cylinder pipes are manufactured according to various international standards to ensure quality and consistency. Some common standards include ASTM, DIN, EN, and ISO.
Cold drawn cylinder pipes can be made from various materials, including carbon steel, alloy steel, stainless steel, and other specialty metals, depending on the application requirements.
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.
