Custom Vacuum 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.
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.
