Abstract
Modular wall manifolds are used to distribute coolant in a data center. These are often large, heavy pipes assembled at heights. Maintaining proper alignment of these pipes is critical to prevent leaks and stress at the joints. Angular misalignment can lead to seal failures, leaks, and system downtime. Achieving the required sub-degree alignment during assembly is challenging due to factors like support structure tolerances, pipe straightness, mounting hardware variations, and manufacturing tolerances. Working at height and with heavy components further complicates precise alignment. This disclosure describes techniques for precise axis alignment of pipe sections and manifolds by aligning the mounting brackets of manifold support hanger on horizontal beams to expedite installation. Support hanger driven alignment is performed via a multi-step process that includes bracket preparation and initial positioning, laser setup and baseline establishment, establishing the straightness axis, fine-tuning bracket alignment, and manifold installation. The described techniques can expedite installation within a production environment while eliminating the need for supplementary angular measurement tools and specialized fixtures. An example use context for the described techniques is in data center liquid cooling manifold assembly procedures.
