Forever Pipe™ Duo-Bar

Up to 92% through-life cost savings with duo-metal casting

Forever Pipe™ Duo Bar is a dual-metal centrifugally cast pipe designed for extreme abrasion environments. A high-chrome white iron bore provides exceptional wear resistance, while the outer steel layer delivers structural toughness and weldability.

The bore is extremely abrasion resistant and gives a 10x wear life compared to weld overlay. The outer layer protects from any impact cracking.

Alloy Range

Typically made with an inner layer of 27% Chrome white iron metallurgically bonded to an outer carbon steel layer. VEEM offers an extensive range of over 250 alloys, including non-ferrous and ferrous options such as stainless steel, nickel, aluminum, copper, and cobalt alloys. View all alloys >

Sizing Options

VEEM boasts the largest range of die sizes in Australia (77mm to 764mm for long dies and up to 1250mm for shorter lengths). Forever Pipe™ Duo-Bar is available in 80NB to 600NB. View complete size list >

Ultrasonic Inspection Capability

Duo-bar materials allow for ultrasonic thickness monitoring to determine the remaining inner wear layer, which is crucial for managing maintenance and preventing unplanned downtime in refineries and high-wear environments.

Centrifugal Casting

Engineered metallurgy for extreme performance

Centrifugal casting is a specialised manufacturing process in which molten metal is poured into a rotating mould. Under centrifugal force, the metal is distributed evenly around the mould, forming a dense, close-grained structure with exceptional structural integrity.

Unlike conventional gravity casting, centrifugal casting produces material that solidifies from the outside diameter inward. This directional solidification significantly reduces defects such as shrinkage, gas porosity, blowholes and non-metallic inclusions, resulting in higher strength, reliability and consistency.

Where Forever Pipe™ outperforms
conventional pipe solutions

Forever Pipe™ is engineered for industries where standard fabricated, welded or coated pipe systems fail under wear, corrosion, heat or mechanical stress. By combining centrifugal casting with engineered alloy systems, Forever Pipe™ delivers extended service life, improved reliability and significantly lower through-life costs across critical industrial applications.

From mining and slurry transport to energy, infrastructure and heavy industry, Forever Pipe™ is designed to perform in environments where downtime is costly and failure is not an option.
