Stone Basalt Cast

Stone Basalt Cast is the best material for the industrial factories which face the problem of an abrasive wear.

Stone Basalt Cast is the best material for the industrial factories which face the problem of an abrasive wear, affecting of severe atmospheres and elevated temperatures to the equipment and constructions used in their production process. Stone Basalt Cast falls into 8th group of mineralogical hardness (т.е actually concedes only to diamond and emery by this parameter) and consequently, its wearing quality considerably exceeds all steels, including the manganese steel, cast iron (incl. IChKh grade), rubbers, plastics and all the rest.

As a rule, surfaces of the equipment and its useful areas at the industrial factories are not protected from destroying affecting of operating environment or protected by ineffective materials. At the same time, more than 90 % of deteriorated area of the equipment and constructions work at pressures less than 5 MPa.

By their mechanical properties, such stonecast products, as:

Acid-proof branch pieces, T-pieces, crosspieces lined by cast basalt insert.
Withstand loads which considerably exceed 5 MPa and consequently can be widely used for protection of the equipment against an abrasive wear, affecting of severe atmospheres and elevated temperatures (Eucor). The demonstrative example of long-term and successful practice of CAST BASALT use is the Starobeshevsky state district power station where separate sections of lined pipeline for ash handling which has been installed in 1967 are still remain.

There is also a number of special properties: low water absorption, fairly good dielectric properties, and also STONE CASTING is not subject to ageing (i.e. its properties do not change with the course of time) and does not form a radioactive dust in case of interacting with radioactive substances.

From the economic point of view there is no concurrence with stone casting. Despite initially higher cost of TUBES LINED by FUSED BASALT, their higher endurance will allow more than six times expenses to save than at use of unlined steel tubes. Products lined by FUSED BASALT not only serve much longer than made of steel, but also you will not further lose time on repair and maintenance.

Being the chemical-resistant material, stone casting successfully replaces lead, alloys, ferrous and non-ferrous metals, acid-proof ceramics, porcelain, granite and some brands of plastics. Having a high mechanical strength and abrasion resistance; CAST BASALT PRODUCTS replace granite and marble in road construction and civil engineering, and are also applied to a decorative coating. Having low heat and electric conductivity, products made from fused basalt in some cases successfully expel porcelain, glass, ceramics and other materials used for the dielectric and heat-insulating purposes.

Industries and sectors of national economy where stone casting is applied:

Application of stone casting in the capacity of the chemical-resistant material

Type of industry and material The service life of steel pipe The service life of lined steel pipe
Iron ores and pulpes 1-2,5 year No less 10 year
Quartz sands Until 2 year No less 7 year
Chemical compound Until 2 year No less 8 year
Ashes from thermal power station 1-2 yea 20-25 year

Flat and shaped cast basalt products are applied to facing of various chemical apparatuses and constructions subject to chemical affecting of severe atmospheres:

Bracing of stonecast parts to bearing walls of chemical apparatuses is carried out by a silicate fireproof luting on the basis of soluble silicate with an acid-proof powder (products of refuse grinding) in the capacity of the chemical-resistant filler. The luting can be also used as an independent refractory.

【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.
