Heavy calibre recombination reducer
Heavy calibre recombination reducer - industrial steel product
Cast basalt lined steel pipe tees are wear-resistant branch fittings designed for abrasive material transport and industrial pipeline distribution systems.
Cast basalt lined steel pipe tees are specially designed wear-resistant branch fittings used to divide, combine or redirect the flow of abrasive materials within industrial pipeline systems. The cast basalt lining provides superior protection against abrasion, erosion and impact wear at critical flow junctions.
Tee fittings are among the most heavily worn components in slurry and bulk material transport systems because flow direction changes often generate turbulence and particle impact. By incorporating cast basalt lining, the service life of the fitting can be significantly extended.
These fittings are widely used in mining, thermal power plants, cement production, steel manufacturing, dredging operations and bulk material handling facilities.
Cast basalt is produced by melting selected natural basalt rock at temperatures exceeding 1250°C and then crystallizing it under controlled conditions. The resulting material exhibits exceptional hardness and wear resistance.
Combined with a robust carbon steel shell, cast basalt lined pipe tees offer a durable and economical solution for severe operating environments where conventional steel fittings experience rapid wear.
Standard and customized tee configurations are available to meet various pipeline design requirements.
A cast basalt lined pipe tee is a branch fitting that connects three sections of pipeline, allowing material flow to split into multiple directions or merge into a single line. The internal cast basalt lining protects the fitting from severe wear caused by abrasive particles and turbulent flow.
Because tees are often located at critical distribution points, enhanced wear protection is essential to maintain system reliability and minimize downtime.

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.
