Abrasion-resistant piping is specially engineered piping designed to withstand material loss caused by abrasive particles traveling through industrial piping systems. Unlike conventional carbon steel pipe, abrasion-resistant piping incorporates specialized wear-resistant materials or protective internal surfaces.

These materials reduce the rate at which abrasive particles remove metal from the pipe wall, helping extend service life and minimize maintenance requirements.

SAS Global Corporation manufactures premium abrasion-resistant piping using SureAlloy® Carbide Overlay Plate and internally hardfaced CLADPIPE™ technology for demanding industrial material transport applications.

The best piping material depends on the type of abrasive material, particle velocity, impact angle, operating temperature, and system configuration.

Common wear-resistant piping solutions include:

• Chromium carbide overlay pipe
• Complex carbide overlay pipe
• Internally hardfaced steel pipe
• Ceramic-lined pipe
• Hardened alloy steel pipe

SAS Global specializes in SureAlloy® Carbide Overlay Pipe and CLADPIPE™ Internally Hardfaced Pipe. These products provide engineered wear protection for applications involving severe abrasion and particle erosion.

The most suitable material should be selected based on actual operating conditions rather than hardness alone.

SAS Global specializes in SureAlloy® Carbide Overlay Pipe and CLADPIPE™ Internally Hardfaced Pipe. These products provide engineered wear protection for applications involving severe abrasion and particle erosion.

The most suitable material should be selected based on actual operating conditions rather than hardness alone.

Conventional carbon steel pipe provides structural strength and material containment but generally has limited resistance to severe abrasive particle wear.

Abrasion-resistant pipe incorporates specialized protective materials designed to resist the cutting, grinding, and erosion caused by abrasive particles.

In demanding applications, wear-resistant piping can provide:

• Longer operating life
• Reduced wall thickness loss
• Fewer premature pipe failures
• Lower replacement frequence
• Reduced maintenance downtime
• Improved system reliability

SAS Global's abrasion-resistant piping systems are designed to provide long-term wear protection in applications where conventional steel pipe experiences accelerated deterioration.

Abrasive wear occurs when hard particles traveling through a piping system repeatedly contact the internal pipe wall, gradually removing material.

Common contributing factors include:

• High particle velocities
• Hard or angular particles
• High solids concentrations
• Turbulent flow conditions
• Changes in piping direction
• Particle impacts at elbows and transitions
• Inadequate wear-resistant materials

The severity of wear depends on particle characteristics, flow conditions, piping geometry, and the properties of the internal pipe surface.

Selecting appropriate abrasion-resistant materials can significantly reduce premature piping deterioration.

Abrasion and erosion are related wear mechanisms that can occur within industrial piping systems.

Abrasion generally involves hard particles sliding, scraping, or grinding against the pipe's internal surface, progressively removing material.

Erosion typically occurs when moving particles repeatedly impact the pipe wall, removing material through high-velocity particle contact.

Both mechanisms can occur simultaneously in pneumatic conveying systems transporting coal, fly ash, cement, minerals, and other abrasive materials.

SAS Global manufactures wear-resistant piping solutions designed to address abrasive and erosive wear conditions.

SAS Global Corporation manufactures two primary categories of abrasion-resistant piping.

SureAlloy® Fabricated Wear-Resistant Pipe

Manufactured using premium SureAlloy Carbide Overlay Plate, providing a highly wear-resistant internal surface for demanding abrasive material transport applications.

CLADPIPE™ Internally Hardfaced Pipe

Manufactured by depositing specialized wear-resistant hardfacing alloys directly onto the inside diameter of steel piping through automated welding technology.

Both solutions are available in custom configurations for industrial applications, including straight piping, elbows, transitions, and specialized piping systems.

SureAlloy® Carbide Overlay Pipe is an abrasion-resistant piping solution fabricated from SAS Global's premium SureAlloy Carbide Overlay Plate.

The internal surface contains hard chromium carbides or complex carbides embedded in a specially engineered alloy matrix, providing excellent resistance to abrasive material transport.

Available material options include:

• SA1750CR® Chromium Carbide Overlay
• SA2000® Complex Carbide Overlay
• SA6000® Advanced Complex Carbide Overlay

SureAlloy piping is commonly used for pulverized coal transport, fly ash conveying, mineral processing, and other severe abrasion applications.

CLADPIPE™ is a premium internally hardfaced cladded piping system manufactured by Cladtec, a division of SAS Global Corporation.

CLADPIPE is produced by applying a specialized wear-resistant weld overlay directly to the inside diameter of steel pipe using automated cladding equipment.

The process creates a metallurgically bonded protective layer designed to withstand abrasive particles and erosion.

CLADPIPE is manufactured in the USA and can be customized with different pipe diameters, lengths, and hardfacing alloys to meet specific industrial operating requirements.

Fabricated carbide overlay pipe and internally hardfaced pipe provide wear protection through different manufacturing processes.

Fabricated Carbide Overlay Pipe: Manufactured by forming premium carbide overlay plate into the required piping configuration. The wear-resistant overlay becomes the internal pipe surface.

Internally Hardfaced Pipe (Cladded Pipe): Manufactured by applying a protective weld overlay directly onto the internal diameter of an existing steel pipe structure.

Both methods provide abrasion-resistant internal surfaces.

The preferred solution depends on piping geometry, diameter, fabrication requirements, operating conditions, and the selected wear-resistant alloy.

SAS Global offers several SureAlloy materials engineered for different abrasive wear conditions.

SA1750CR®: Premium chromium carbide overlay designed for severe sliding abrasion and consistent wear protection.

SA2000®: Advanced complex carbide overlay offering improved abrasion resistance with additional toughness and temperature stability.

SA6000®: Patented complex carbide technology engineered for demanding applications involving abrasion and impact.

RapidFlow®: Premium smooth-surface carbide overlay designed to reduce friction and material buildup.

The appropriate material depends on abrasion severity, particle characteristics, impact loading, operating temperature, and maintenance objectives.

SAS Global's CLADPIPE is manufactured in various diameters and lengths to accommodate industrial piping applications.

Standard manufacturing capabilities include:

• Finished internal diameters from 5.5 inches to 26 inches
• Special configurations up to 30 inches internal diameter, depending on specifications
• Internal hardfacing thicknesses from 1/8 inch to 1/2 inch, depending on material
• Custom pipe lengths and configurations

CLADPIPE is typically manufactured using heavy-wall steel pipe with a precision-applied internal wear-resistant overlay.

Customers should contact SAS Global to confirm availability for specific dimensions and operating requirements.

Yes. SAS Global manufactures custom abrasion-resistant piping components engineered for specific equipment configurations and industrial operating conditions.

Available solutions include:

• Straight pipe sections
• Fabricated gored elbows
• Wear-resistant bends
• Pipe transitions
• Custom piping configurations
• Complete fuel piping systems
• Replacement piping assemblies

Components can be manufactured using SureAlloy Carbide Overlay Plate or internally hardfaced CLADPIPE technology.

Custom designs help protect localized high-wear areas and accommodate existing piping layouts.

Pipe elbows and bends frequently experience accelerated abrasive wear because particles change direction as they travel through the piping system.

Particle momentum causes abrasive solids to strike the internal pipe wall, creating concentrated impact and erosion.

Wear severity depends on particle velocity, solids loading, elbow geometry, and material characteristics.

High-wear areas commonly occur along the outside radius of elbows, although actual wear patterns vary with flow conditions and geometry.

SAS Global manufactures abrasion-resistant elbows and piping components using premium carbide overlay and hardfacing technologies to protect these vulnerable locations.

Pulverized coal piping requires materials capable of resisting continuous abrasive particle movement, localized erosion, and wear caused by changes in flow direction.

Chromium carbide and complex carbide overlay piping are commonly used for these applications.

SAS Global manufactures SureAlloy Carbide Overlay Pipe and CLADPIPE Internally Hardfaced Pipe for coal-fired power generation facilities.

These systems are designed to protect straight piping, elbows, transitions, and other high-wear components within pulverized coal transport systems.

Material selection should consider coal characteristics, air-to-fuel ratio, conveying velocity, and existing piping wear patterns.

Fly ash pneumatic conveying systems can experience significant internal pipe erosion due to continuous transport of abrasive particles.

Wear-resistant piping options include chromium carbide overlay pipe, complex carbide overlay pipe, internally hardfaced pipe, and other engineered lining systems.

SAS Global offers SureAlloy Carbide Overlay Pipe and CLADPIPE for applications requiring improved resistance to fly ash abrasion and erosion.

The best solution depends on conveying velocity, ash characteristics, solids concentration, piping geometry, and operating temperature.

Material velocity is an important factor affecting abrasive wear in pneumatic conveying systems.

As particle velocity increases, the energy associated with particle impacts generally increases, potentially accelerating internal pipe erosion.

However, the relationship between velocity and wear depends on particle characteristics, impact angle, material properties, and conveying conditions.

Excessive velocity may significantly shorten piping service life, particularly at elbows and transitions.

Proper system design, operating velocity, and wear-resistant material selection can help reduce premature piping deterioration.

Abrasion-resistant piping is particularly valuable in industries transporting abrasive solids through pneumatic or mechanical conveying systems.

Common industries include:

• Coal-fired power generation
• Mining and mineral processing
• Cement manufacturing
• Steel production
• Foundry operations
• Aggregate processing
• Bulk material handling

Typical applications include coal piping, ash transport lines, cyclone piping, classifier connections, mineral conveying systems, and industrial material transfer lines.

SAS Global provides engineered piping solutions designed for the demanding operating conditions found in these industries.

Abrasion-resistant piping can help reduce failures caused by progressive internal abrasive wear.

As abrasive particles remove material from a pipe's internal surface, the remaining wall thickness decreases. If wear continues unchecked, the pipe may eventually develop leaks or lose its ability to safely contain the transported material.

Properly selected wear-resistant piping can slow this deterioration and extend replacement intervals.

However, abrasion-resistant materials do not eliminate the need for inspection, maintenance, and appropriate piping system design.

The service life of abrasion-resistant piping varies significantly depending on operating conditions and material selection.

Factors affecting service life include:

• Abrasive material characteristics
• Particle velocity
• Solids concentration
• Operating temperature
• Pipe diameter and geometry
• Impact angle
• Internal wear-resistant material

Properly selected carbide overlay or internally hardfaced piping can provide substantially longer service life than conventional carbon steel piping in severe abrasion applications.

SAS Global can help evaluate operating conditions and existing component performance to identify suitable wear-resistant piping solutions.

Industrial facilities can monitor piping wear through scheduled inspections and wall-thickness measurements.

Ultrasonic thickness testing and other suitable nondestructive inspection methods can help identify areas of material loss.

By recording wall-thickness measurements over time, maintenance personnel can evaluate wear trends and estimate future replacement requirements.

Critical inspection locations typically include elbows, bends, transitions, and other areas exposed to concentrated particle impact.

Inspection methods and replacement criteria should account for the piping material, internal overlay, operating conditions, and applicable engineering requirements.

Yes. Properly selected abrasion-resistant piping can reduce maintenance costs by extending component service life and decreasing replacement frequency.

Potential benefits include:

• Fewer piping replacements
• Reduced maintenance labor
• Less emergency repair work
• Improved outage planning
• Lower replacement material costs over time
• Increased operating availability

Although premium wear-resistant piping may have a higher initial purchase price than conventional steel pipe, longer service life can reduce the overall cost of ownership.

Actual savings depend on operating conditions, installed costs, and service life achieved.

In certain applications, internally hardfaced piping may be suitable for rebuilding or refurbishment.

SAS Global's CLADPIPE technology allows wear-resistant hardfacing to be applied to the internal pipe surface.

Whether a worn pipe can be refurbished depends on the condition of the base material, remaining wall thickness, structural integrity, and operating requirements.

A technical inspection is necessary to determine whether rebuilding is practical and appropriate.

Rebuilding suitable components may help reduce replacement costs and extend the useful life of industrial piping assets.

Selecting the correct abrasion-resistant piping system requires evaluating the material being transported, operating conditions, and existing wear problems.

Important considerations include:

• Abrasive material type and hardness
• Particle size and concentration
• Conveying velocity
• Pipe diameter and length
• Operating temperature
• Elbow and transition geometry
• Current piping service life
• Maintenance and replacement requirements
