Mill-direct 316L stainless pipe, butt-weld fittings and lap-joint flanges — supplied to your project mechanical specification, container-optimised, and ready to weld.
Everything for the wetted stainless loop — pipe, butt-weld fittings, and the lap-joint flange sets that keep only stainless and gasket in contact with the coolant.
Welded or seamless austenitic pipe, pickled and passivated, bevelled and ready for orbital or manual GTAW.
Wrought 316L fittings matched to pipe wall — long-radius elbows, equal tees, concentric reducers and caps.
Van-Stone arrangement: a 316L angle-face ring butt-welded to the pipe, with a loose galvanised backing flange — only stainless and gasket touch the fluid.
Matched consumables to complete the demountable joints — reinforced neoprene gaskets and stainless bolt sets, packed by joint.
Wall thickness is set by size; test pressure is 1.5× design or 1 MPa, whichever is greater. Confirm the governing figures against your project mechanical specification.
| Nominal size | Wall (min) | Design — CDU | Test — CDU | Other systems |
|---|---|---|---|---|
| DN25 – DN50 | 1.6 mm | 3.0 MPa | 4.5 MPa | 1.0 MPa |
| DN65 – DN100 | 1.6 mm | 3.0 MPa | 4.5 MPa | 1.0 MPa |
| DN125 – DN150 | 1.6 mm | 3.0 MPa | 4.5 MPa | 1.0 MPa |
| DN200 – DN300 | 2.0 mm | 3.0 MPa | 4.5 MPa | 1.0 MPa |
Joints — permanent: GTAW butt-weld, passivated. Demountable: lap-joint flanged (316L ring + galvanised backing). Valves ≤DN50 female threaded; >DN50 flanged / wafer between flanges. Grooved couplings not accepted.
Surge and overflow supply when OEM lead-times and grid-connection dates don't line up.
Bridge the gap between specified dates and OEM lead-times with stock-backed, mill-direct supply sized to your programme.
Thin-wall stainless cubes out before it weighs out — we load and cost 40 ft containers by volume, with a live BOQ per shipment.
Mill certificates, heat traceability, passivation and an inspection & test plan — the document set that gets goods released and paid.
Bevelled, capped and cleaned to keep bores dry in transit — pipe and fittings arrive fabrication-ready for orbital or manual GTAW.
