Cast basalt composite cross fittings are used for four-way flow distribution in high wear industrial pipeline systems.
A cast basalt composite cross is a four-way pipe fitting that allows flow distribution or collection in multiple directions within a pipeline system.
It consists of a steel outer shell and an internal cast basalt lining that protects against abrasion and erosion caused by high-velocity particle flow.
Cross fittings are among the most critical wear points in a pipeline because they involve multiple flow intersections.
The collision of particles from different directions creates turbulence and high-impact erosion zones.
Without proper protection, conventional steel crosses often fail prematurely.
| Component | Function |
|---|---|
| Steel Outer Shell | Provides mechanical strength and pressure resistance. |
| Cast Basalt Lining | Protects against abrasion and erosion. |
| Bonding Layer | Secures lining inside cross junction. |
| Four-Way Junction | Enables multi-directional flow distribution. |
| Type | Description |
|---|---|
| Equal Cross | All four branches have the same diameter. |
| Reducing Cross | Branch diameters vary according to system design. |
| 90° Cross | Standard perpendicular flow distribution. |
| Custom Cross | Manufactured based on engineering drawings. |
Enables efficient pipeline distribution.
Suitable for abrasive slurry systems.
Reduces failure at junction points.
Extends maintenance intervals significantly.
Cast basalt is a highly wear-resistant and corrosion-resistant lining material widely used in pipes, chutes, bunkers, cyclones, and hoppers.
Usage
Installation
Cast basalt has become the global standard for ash slurry pipelines in fossil-fuel power stations and other heavy industries. It significantly extends equipment service life in environments with severe abrasion and corrosion.
It is commonly used as a cost-effective lining material for steel, cast iron, rubber, or polyurethane equipment, offering 5–10 times longer service life than traditional materials.
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.
