Jiangsu Xingrui Piping Co., Ltd

Oxygen Lance Pipe, are small diameter pipes used with oxygen is an invaluable tool for the primary metals industry. It is used daily in almost all ferrous and non-ferrous primary production facilities.

Calorised Steel Pipe is continuously hot dip diffusion coated inner & outer with an aluminum coating according to the standard of GB/T18592-2001.The hot dip diffusion process, pioneered by Xingrui, provides a tight metallurgical bond between the steel and the coating,lance pipe lasts five to seven times longer than mid steel pipe in oxygen injection,also shorten the tap-time in the oxygen enrichment operation
In our calorising process, the diffusion layer formed is a mixture of iron and aluminides, dependent on the substrate material, with an aluminium content of between 30 and 45 wt. % at the surface. The percentage of aluminium gradually decreases through the diffusion zone to that of the substrate material.
This process results in a material with the strength of steel plus the corrosion protection of aluminum, and the synergistic heat protection of an aluminum alloy,high temperature resistance can reach to 600℃。

Ceramic coated pipe is a carbon steel pipe with multiple, thin layers of ceramic coating both outer and inner. The ceramic coating is resistant to slag attack and extends the life of the pipe when it is immersed into molten metal or in high temperature atmospheres. The applications include powder injections, tap-hole cleaning and opening nozzles in ladles, tundishes and launders.
Ceramic coated pipe was developed to increase the lance life beyond conventional calorized or black pipes. Due to innovative methods of refractory deposition for interior and exterior coatings, it provides unequaled lance life at lower cost. A special ceramic coating has been developed for copper smelter applications.
