Metraflex: Pipe Expansion Joint

December 31, 2011
Pipe Expansion JointThe Metraloop® has achieved NSF 61, annex G certification for use with potable water, complying with California’s Health & Safety Code Section 116875 (commonly known as AB 1953). An extremely flexible and compact expansion joint, the Metraloop has none of the pressure thrust loads of conventional bellows-type joints and negligible spring rates, the company says. It needs no anchoring, thrust blocks or structural steel, and little or no guiding. It flexes before the pipe begins to bow and before any significant loads are imposed at anchor points to the building.
