High-purity iridium tubes offering exceptional corrosion resistance, ultra-high temperature stability and precision fabrication for demanding industrial applications.
Precision Iridium Tubes for Crystal Growth, Semiconductor Processing, Glass Manufacturing and Ultra-High Temperature Applications
Iridium tubes are precision-fabricated from high-purity iridium and are designed for applications requiring exceptional thermal stability, outstanding corrosion resistance and reliable performance in extreme operating environments. Their excellent resistance to oxidation and molten oxide attack makes them an ideal solution for crystal growth equipment, semiconductor processing systems, laboratory furnaces and high-temperature industrial applications.
Compared with conventional platinum or refractory metal tubes, iridium tubes provide higher temperature capability, superior dimensional stability and excellent chemical inertness. These characteristics significantly reduce contamination during high-purity material processing while extending component service life.
Sunny Steel supplies seamless and fabricated iridium tubes in standard and custom dimensions. Precision machining, polishing, welding and custom fabrication services are available according to customer drawings and technical specifications.

To ensure reliable performance in demanding industrial environments, every iridium crucible is manufactured under strict quality control procedures and inspected before delivery.
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.
