304 Or 316L Custom Double Layer Water Cooling Vacuum Pipeline

Precision-Engineered Vacuum Welded Pipes for High-Integrity Systems

Custom Double-Layer Water Cooling Pipeline

Vacuum welded pipes are the gold standard for high-vacuum and ultra-high-vacuum (UHV) applications where absolute leak-tightness, structural integrity, and corrosion resistance are non-negotiable. Unlike mechanically joined or seamless drawn pipes, vacuum welded pipes are fabricated using automated orbital welding techniques, creating a homogenous, seam-free joint that withstands extreme pressure differentials and thermal cycling. These pipes are essential for semiconductor manufacturing, research chambers, pharmaceutical freeze-drying, and aerospace testing facilities.

Key Features & Characteristics

Our vacuum welded pipes are manufactured from certified stainless steel grades (304L, 316L, and 316LN) in controlled cleanroom environments. Distinguishing features include:

  • Full-Penetration Orbital Welds: Automated welding ensures 100% root fusion without cracks or porosity, eliminating virtual leaks.

  • Electropolished Inner Surfaces: Achieves Ra ≤ 0.25 µm (10 µin) surface finish, minimizing outgassing and particle entrapment.

  • Leak-Tight Integrity: Helium leak tested to rates as low as 1×10⁻⁹ mbar·L/s or better.

  • Bakeable & UHV Compatible: Designed for operating temperatures up to 400°C (with appropriate flanges) without degradation.

  • Seamless Transition Zones: Smooth internal weld profiles prevent turbulence and allow consistent conductance.

  • Full Traceability: Each pipe batch includes material certifications, weld logs, and helium leak test reports.

Conclusion

For high-vacuum systems where every leak counts, vacuum welded pipes offer unmatched reliability, cleanliness, and performance. Whether you are designing a new UHV deposition chamber or upgrading an existing pharmaceutical freeze-dryer line, welded pipe assemblies eliminate chronic leak points and reduce lifecycle costs. Contact our vacuum engineering team to review your process requirements—including desired base pressure, bakeout needs, and gas compatibility—and we will supply fully documented, helium-tested vacuum welded pipes tailored to your exact specifications. Choose welded integrity; choose long-term vacuum stability.
