HFI Pipe
High Flow Index (HFI) pipes for various industrial applications.
Cold Drawn ERW (Electric Resistance Welded) pipes, their characteristics, applications, and differences from CDW, CDS, and MS pipes.
Cold Extruded Welded (CEW) tube is one of the best choices for the manufacture of multi-stage hydraulic cylinders. Its process is the same as that of cold drawn precision seamless tubes. It is precision drawn by electric resistance welding (ERW) and manufactured to EN. 10305-2 EU standard for mechanically cold-drawn welded carbon steel tubes.
After the electric resistance welded pipe is welded, the whole pipe body is normalised to ensure the homogeneity of the weld and the heat affected zone with the rest of the metallographic structure and mechanical properties; cold drawing and subsequent heat treatment (elimination of internal stress) and the steel pipe has good dimensions and mechanical properties.
Cold Drawn ERW pipes are widely used in industries such as petroleum, oil and gas, and petrochemicals, where high precision dimensional tolerances and superior surface finishes are critical.
DOM (Drawn Over Mandrel) refers to a high-precision steel tubing product produced by a cold drawing process. This method enhances the dimensional accuracy, surface finish, and mechanical properties compared to other tubing types.
DOM tubing is preferred over other types like hot-finished seamless or standard ERW due to:
Compared to other tubing (e.g., hot-finished seamless or standard ERW), DOM tubing provides:
DOM tubing is commonly chosen for applications that demand high strength, precision, and reliability. If you'd like to learn more about DOM tubing or discuss its applications further, let me know!

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.
