Core Challenges
Tight Space
CDU cabinets leave minimal room — standard valves simply don't fit.
Difficult Operation
Conventional valves are hard to open and close in confined spaces.
Leakage Risk
Bolted connections create leak paths inside the CDU over time.
PHE Clogging
Particulate buildup blocks heat exchanger microchannels.
How We Solve Pipeline System Solution Challenges
Compact Isolation
Low-torque operation in the tightest spaces. One-piece welded body — no bolted joints, no leak paths. Triple-sealed mid-head with patented anti-leak stem design keeps fluid contained even under abnormal conditions.
Recommended Products:
Vibration Absorption
Fully automatic welded seams — zero leakage at 1.6MPa. Electropolished surface eliminates micro-cracks, triples fatigue life. Flexibly compensates pump vibration and thermal expansion to prevent pipe rupture.
Recommended Products:
Vibration Absorption
Precision Flow Control
Proportional control for accurate flow regulation. Electric actuation enables remote operation and automated CDU control.

Precision Flow Control
Channel Protection
Multi-layer sintered mesh captures particulates before they settle in cooling channels. Backwashable for repeated use, it protects heat exchangers and piping from long-term clogging in continuous operation.
Recommended Products:
Balanced Flow Distribution

Frequently Asked Questions

How do fully welded piping systems prevent leakage in main cooling loops?

 
 

Fully welded one-piece butterfly valves and piping eliminate flanged and threaded joints — the most common leak sources in long distribution pipe runs. No mechanical joints means no leak paths.

What is the benefit of prefabricated piping modules for data center cooling?

 
 

Prefabricated piping modules shift over 90% of welding from the job site to our ISO 3834 certified factory. On-site work is reduced to standard connections, cutting installation time by over 70%.

Can branch lines be repaired without shutting down the main cooling loop?

 
 

Yes. Our inline-maintenance butterfly valves allow branch servicing by closing the disc and removing six flange bolts — the main loop stays pressurized and operational throughout the repair.

What prevents thermal expansion from damaging rigid cooling loop piping?

 
 

Metal bellows with braided reinforcement absorb axial, lateral, and angular displacement caused by thermal expansion and mechanical vibration — protecting pipe connections from stress fatigue.
