Cutting & bending
Spools formed to isometric drawings with controlled bend radii.
Materials & fabrication
Material selection, joint method and surface condition are decided together with the coolant chemistry and the acceptance criteria.

Materials
Prime virgin steel from named mills, with documentation attached to every batch.
| AISI 304 | General closed-loop coolant and utility distribution |
|---|---|
| AISI 316L | Higher chloride resistance; specified for DI water and aggressive cleaning regimes |
| Tube form | Seamless, with controlled internal roughness |
| Wall thickness | 0.8 - 3.0 mm typical; project-specified |
| Traceability | EN 10204 3.1 Mill Test Certificates: chemical composition and mechanical values |
| Incoming checks | On-site laboratory, spectrometer and dimensional verification |
Coolant compatibility is reviewed per project. Final material grade is confirmed at engineering review, not assumed from this table.
Fabrication
Forming, welding, sizing and testing run under one roof in Foshan.
Spools formed to isometric drawings with controlled bend radii.
Orbital and argon-shielded welding with post-fabrication passivation.
V and M profile press connections for flameless assembly.
Automated forming and sizing lines; ductility checks by flattening / widening.
Online ultrasonic scanning, dimensional inspection, on-site laboratory.
100% helium leak testing and hydraulic pressure testing on custom assemblies.
Standards
Precision here protects both of us - and matters for Google Ads review and procurement audits.
ISO 9001 compliance describes our quality management system.
NSF / WRAS standards are potable-water material and component standards. They describe materials, not a liquid cooling system approval.
DVGW W534 is a press-fitting test standard. We describe our fittings as tested to it, not as certified liquid cooling equipment.
Mill Test Certificates (MTC, EN 10204 3.1) are material traceability documents supplied with the batch.
None of the above is a system-level liquid cooling certification. If your project requires a specific third-party system approval, tell us at inquiry stage so it can be scoped explicitly.
