Clean media compatibility
Deionised water and glycol blends demand tube and fittings that do not shed particulates or leach ions into the loop.
Industries / Semiconductor
Ultra-Clean Process Cooling Loops for Semiconductor Tools
Closed-loop distribution for process tools where particulate, ionic contamination and an unplanned leak all carry the same cost: a stopped fab.
Application requirements
What This Application Demands
The pipework is specified by the failure modes it has to prevent, not by a catalogue part number.
Joint integrity
Every welded or pressed joint is a potential particle trap and leak path. Joint method and internal bead profile are specified, not assumed.
Dimensional repeatability
Tool-bay skids must match interface drawings exactly so that replacement or expansion does not require field rework.
Traceable material
Heat numbers, chemical composition and mechanical values stay attached to each batch through fabrication and shipment.
Where our piping fits
Components We Build for This Application
Complete loops are engineered to your P&ID or CAD package; these are the building blocks we fabricate in-house.
Seamless 316L distribution headers
Multi-port manifolds with welded branch outlets, passivated after fabrication.
Made to drawing
Tool-side prefabricated spools
Cut, bent and formed to bay drawings with flanged or pressed ends.
Made to drawing
CDU interface blocks
Valve-integrated blocks matched to the tool's flow and isolation scheme.

Typical configuration
Specified Per Project
The table below describes the parameters we normally agree at engineering review. Nothing here is a fixed catalogue SKU - final values follow your drawing, coolant and acceptance criteria.
NSF / WRAS material standards and DVGW W534 fitting tests describe materials and components; they are not semiconductor-process or system-level certifications.

Delivery
From Drawing to a Tested Assembly
One engineering team owns the loop from manufacturability review through to the leak-test record.
- Send the drawingP&ID, isometric or CAD package with flow rates, coolant type and interface points.
- Engineering reviewMaterial compatibility, wall thickness, joint method and routing checked, with a manufacturability proposal returned.
- FabricationIn-house cutting, bending, welding, passivation and dimensional inspection under one roof in Foshan.
- VerificationHelium leak test, hydraulic pressure test and MTC documentation before export packing.

Semiconductor Piping: Common Questions
Short answers grounded in what we actually fabricate and test.
What tubing grade do you use for ultra-clean process cooling loops?
We work in AISI 304 and 316L seamless stainless tube. The grade is selected against the coolant chemistry and cleaning regime at engineering review, and the batch is supplied with EN 10204 3.1 mill test certificates.
How do you keep the internal surface clean after fabrication?
Cutting, bending, orbital welding and passivation are done in-house in Foshan, then the assembly is cleaned and its interfaces capped before export packing. The internal bead profile and cleaning method are agreed against your drawing before cutting starts.
Do you design the loop or build to our drawing?
We fabricate to your P&ID, isometric or CAD package. Our engineering review returns manufacturability feedback on material, wall thickness, joint method and routing; we do not issue a system-level certification.
