Heavy calibre recombination reducer - industrial steel product
Cast basalt composite S pipes are specially designed for smooth directional changes and severe wear applications in industrial pipeline systems.
Cast basalt composite S pipes are specially engineered wear-resistant pipe fittings designed to provide smooth directional changes in abrasive material conveying systems. By combining the structural strength of steel with the exceptional wear resistance of fused cast basalt, these pipes deliver long service life and reliable performance under severe operating conditions.
The S-shaped configuration allows material flow to transition smoothly between different elevations or directions while reducing turbulence and localized impact. Compared with multiple standard elbows, an S pipe can often provide a more compact and efficient pipeline layout.
In high-wear applications involving coal powder, fly ash, mineral slurry, clinker, sand and bulk solids, cast basalt composite S pipes significantly reduce maintenance frequency and replacement costs.
The internal lining is manufactured from carefully selected volcanic basalt that is melted at temperatures exceeding 1250°C and then crystallized under controlled conditions. The resulting material exhibits outstanding hardness, abrasion resistance and chemical stability.
These S-shaped pipe sections are widely used in power plants, mining operations, cement factories, steel mills, dredging projects and pneumatic conveying systems where conventional steel fittings experience rapid wear.
Custom dimensions, radii and connection types can be supplied according to project specifications.
A cast basalt composite S pipe is a specially shaped pipeline component featuring an S-type flow path and an internal wear-resistant cast basalt lining. It is designed to redirect the flow of abrasive materials while minimizing turbulence, impact wear and pressure loss.
The pipe consists of a fabricated steel shell and precision-machined cast basalt lining sections. The steel structure provides strength and pressure resistance, while the basalt lining protects against erosion, abrasion and corrosion.
Due to its unique geometry, the S pipe is commonly used where pipeline routing requires two directional changes within a relatively short distance.
In many conveying systems, multiple elbows are used to achieve directional changes. However, each elbow introduces turbulence and creates concentrated wear zones where particles impact the pipe wall.
An S pipe integrates two directional transitions into a single component, creating a smoother flow path and reducing the number of welded joints. This can improve conveying efficiency while simplifying installation.

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.
