304 Stainless Steel Coolant Manifold, 4/6/8 Branch, Built to Drawing

Quick Answer304 Stainless Steel Coolant Manifold, 4/6/8 Branch, Built to Drawing — an IDCPDU Manifold for liquid-cooling loops.

304 stainless, TIG welded and passivated — Weld seams are pickled and passivated after welding, which is where chloride pitting starts in a water loop.
4 / 6 / 8 branches, valve per branch — A ball valve on each branch isolates one circuit for service while the rest of the loop stays live.
Pressure test and material certificate — Each manifold ships with a tightness report and mill certificate, which is what the commissioning file needs.
Custom builds in 7 days — Length, branch spacing and port size are made to drawing, and the quoted lead time counts from drawing approval, not from order date.

Four, six or eight branch outlets on a single 304 stainless body
Male-thread run and branch ports, argon-purged welded joints
Pickled and passivated, pressure and tightness tested before dispatch
The body is built from 304 stainless tube, with 316L available for water that carries chlorides. Branch spacing, overall length, port size and branch count are cut to the customer drawing, and a sample can be run before the batch to confirm the fit.
Every joint is TIG welded under argon shielding, so the weld root stays clean on the inside of the tube and no oxide scale is left in the flow path. After welding the whole part is pickled and passivated to restore the passive layer, which is where a stainless manifold normally starts to corrode first.
Each unit is pressure tested and checked for tightness before packing. Material certificates, pressure test reports and tightness reports can be issued with the shipment when the project needs the paperwork.
It feeds the primary and secondary loops of a CDU, ring-main pipework and the water supply of a rack. A ball valve can be fitted on each branch for single-circuit isolation, and volume orders ship in wooden crates with foam inserts so the threads arrive undamaged.

Frequently Asked Questions

Can the branch count be changed?

Yes. 4, 6 and 8 branches are the standard builds; other counts, spacings and lengths are cut to your drawing.

What thread do the ports use?

Run and branch ports are male thread. Tell us the thread standard and size when ordering so the mating fittings are checked against it.

Can each circuit be shut off separately?

Yes. A ball valve can be fitted on each branch, so one circuit can be isolated while the rest keeps running.

How is the surface finished?

The part is pickled and passivated after welding to restore the passive layer on the weld and the heat-affected zone.

What test documents are supplied?

Material certificate, pressure test report and tightness report can be issued with the shipment on request.

How long does a custom build take?

Custom manifolds ship within 7 days after the drawing is confirmed.
