Cast Iron: Provides good abrasion resistance for many applications.
Carbon Steel with Hard Coatings (e.g., Chromium Carbide): Common in
severe abrasive conditions.
Ceramic-Lined: These fittings have a ceramic lining that provides
excellent wear resistance.
Polyurethane & Rubber Linings: Used for applications involving wet
slurries or where a flexible and wear-resistant liner is required.
Abrasion-Resistant Steels (e.g., AR400, AR500): Common for high-wear
environments.
Elbows: Used to change the direction of the pipe, these are commonly
reinforced with abrasion-resistant materials.
Reducers: Designed to reduce the pipe diameter while maintaining wear
resistance.
Tees: Used to split or combine flow, these are built to handle abrasive
material flow through multiple branches.
Couplings and Adapters: Abrasion-resistant couplings are used to join
pipes while preventing wear at the connection point.
Ceramic Lining: Often used in high-wear applications, it can significantly
extend the lifespan of the fittings.
Chromium Carbide Coatings: These hard coatings are applied to the inner
surface of the fittings to resist abrasion.
Rubber or Polyurethane Lining: For wet, slurry, or corrosive
environments, providing flexibility and resistance to both abrasion and
corrosion.
Wall Thickness: Abrasion-resistant pipe fittings often have thicker walls compared to standard fittings to increase their lifespan.
Durability: The lifespan depends on the material and the severity of the abrasion, but these fittings are typically designed to last much longer than standard pipe fittings.
Mining and Minerals Processing: Transporting ores, rocks, and slurries.
Cement and Concrete: Handling cement powder, aggregates, and other abrasive materials.
Power Generation: Ash handling, coal transport, and similar applications.
Chemical and Petrochemical: For handling abrasive chemicals and slurries.
Installation: Usually straightforward but requires careful alignment to minimize wear at joints and connections.
Maintenance: Regular inspection is necessary to monitor wear, and in some cases, the liners or coatings can be replaced without replacing the entire fitting.
ASTM A532: A standard specification for abrasion-resistant cast iron fittings.
ASME B16.9: Standards for dimensions and tolerances for welded fittings, including those used for abrasion-resistant applications.
