Cast basalt pipe is a type of pipe made from basalt rock using a casting process. Basalt is a volcanic rock that is formed from the solidification of lava. Cast basalt pipe is manufactured by melting raw basalt at high temperatures and then pouring it into a mold to take the shape of a pipe.

The resulting cast basalt pipe has excellent properties such as high hardness, resistance to abrasion, and good heat resistance. It is known for its exceptional wear and corrosion resistance, making it suitable for various applications where the pipe needs to withstand harsh conditions. Cast basalt pipe is commonly used in industries such as mining, steel making, power generation, and chemical processing, where it is used to transport abrasive materials, corrosive fluids, and hot gases or liquids.

After selective quarrying, the volcanic rock is melted at a temperature of around 1500ºC and cast into molds or spun into cylinders. The castings so produced are then subjected to heat treatment cycles in special kilns to produce re-crystallized basalt. The product thus produced inherits inertness of parent material. Its micro crystalline, non-porous texture being denser and more homogenous than raw basalt, acquires exceptionally high abrasion resistance.

What size is a cast basalt pipe?

Straight pipe lengths come in diameters from 50mm to 700mm, and 500mm in length. It is also possible to line lobster back bends with bend diameters ranging from 50mm to 700mm. The thickness of the basalt depends on the diameter. It ranges from 20mm to 25mm.

What is basalt lining?

Cast basalt lining is a wear resistant solution that is based on minerals. It handles and processes the components that convey abrasive elements. The cast basalt liners and tiles are manufactured by melting volcanic rocks. They are then casted in the form of different shapes including cylinders and tiles.

【H】 Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

【H】 Cast basalt lined steel pipe

Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.

【H】 Ceramic Tile Lined Pipes

Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.

【H】 Rare earth alloy wear-resistant pipe

The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.

【H】 Tubes Erosion Shields

Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.

【H】 ASTM A213 T91 Alloy Tube

The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
