Piping Components for Liquid Cooling Systems

ISO standard tubes, fittings, connectors, manifolds, and accessories — electropolished finish for ultra-clean coolant transport across the entire secondary loop.
Choose Your Configuration
Ultra-clean tubes, fittings, and custom manifolds for rack-level distribution — electropolished finish and auto-welded sealing for contamination-free transport.
Not Sure Which Valve Fits Your Cooling Loop?
Every cooling loop has unique isolation requirements. Describe your application and our engineers will recommend the right butterfly valve type and configuration.
Our Advantages
The QINFENG Valve Difference
Mirror-Smooth Inner Surface
Mirror-Smooth Inner Surface
Electrolytic polishing eliminates micro-cracks — inner walls mirror-grade smooth. No particulate shedding, no coolant contamination, no cold plate clogging over the system lifetime.
Precision Laser Cutting
Precision Laser Cutting
Every piping component is laser-cut for precision dimensional accuracy. Consistent edge quality and tight tolerances ensure perfect fit-up for welding and assembly — eliminating variability from manual cutting.
Prefabricated System Integration
Prefabricated System Integration
Distribution pipes and manifolds custom-built to your rack layout. Factory pre-assembled and pressure-tested — delivered ready for plug-and-play connection.
Material Traceability
Material Traceability
Full MTR documentation for all 316L stainless steel components. Every batch traceable from raw material to finished product — supporting your compliance and acceptance requirements.

Why is electropolished piping important for liquid cooling systems?

 
 

Electropolished inner walls eliminate surface micro-cracks and achieve mirror-grade smoothness. No particulate shedding, no coolant contamination, and no cold plate microchannel clogging over the system lifetime.

What ISO standards apply to liquid cooling piping components?

 
 

ISO 2852 for quick connectors, ISO 1127 and DIN 11850 for tube dimensions, ASME BPE for high-purity applications, and 3A sanitary standards for surface finish compliance.

How are prefabricated manifolds tested before delivery?

 
 

Every prefabricated manifold is factory pre-assembled and 100% pressure-tested before shipment. Delivered ready for plug-and-play connection — no on-site fabrication or welding required.

What precision manufacturing processes ensure piping component quality?

 
 

Laser cutting ensures precise dimensional accuracy and consistent edge quality. Every component undergoes dimensional inspection and surface finish verification to Ra ≤ 0.4μm before shipment.
