Victaulic, a world leading manufacturer of mechanical pipe-joining systems, introduces the Style W256 Expansion Barrel, a solution for large-diameter water and abrasive service piping systems that accommodates up to 1,067 mm (42”) of in-line expansion and contraction. The Expansion Barrel simplifies system design and installation, and offers durable, reliable service.

The Style W256 Expansion Barrel simplifies system design by enabling all in-line movement to be accommodated in one location in a single unit. It eliminates the need for space-consuming, expensive expansion loops or multiple expansion compensators along the line. Standard Victaulic Style W07 AGS rigid couplings are used to join the barrel to the pipeline, easing installation.

The barrel is constructed of durable ductile iron and features redundant engineered seals for reliable, long service life. An external coating on the inner barrel reduces the risk of seizing and adds a level of wear resistance while reducing activation forces. Specially designed integrated wipers maintain contact to shed away foreign materials, reducing seal wear. The triple redundant seals eliminate the need for field maintenance required with packing glands.

The Style W256 Expansion Barrel is available in 600 to 1,050 mm (24- to 42”) sizes and accommodates pressures of up to 2,065 kPa and straight-line movement of up to 1,067 mm. The Style W256 does not accommodate system deflection.
