Core Challenges
Leakage
Flanged and threaded connections are the weak points in any long pipe run.
Pipe Rupture
Vibration and thermal expansion stress rigid connections to the breaking point.
Complex Installation
On-site welding across long pipelines is slow and quality-dependent.
Maintenance Downtime
Branch repairs require draining the main loop and shutting down operations.
How We Solve Pipeline System Solution Challenges
Zero-Leak Isolation & Inline Maintenance
One-piece welded body with gear-driven turbine handle — low-torque operation on large diameters. Close the valve, remove six bolts, service the branch without shutting down the main loop.
Flexible Compensation
Automatic welded seams — zero leakage at 1.6MPa. Absorbs thermal expansion and mechanical vibration to prevent pipe rupture at connection points.
Recommended Products:
Flanged Metal Bellows   
Vibration Absorption
Precision Flow Control
Proportional control for accurate flow regulation. Electric actuation enables remote operation and automated pipeline control.
Precision Flow Control
Channel Protection
Multi-layer sintered mesh captures particulates before they settle in cooling channels. Backwashable for repeated use, protecting heat exchangers and piping from long-term clogging.
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.
