XMS Heavy Industries

UHV & XHV Chamber Bodies. Built to Print, Leak Tested.

Ultra-high and extreme-high vacuum chambers, weldments, converters and convoluted tubing — designed and welded in-house for research, semiconductor, medical and industrial programs. Benchtop to building scale.

TUBE · FLANGE BOTH ENDS NOMINAL VIEW · CHOOSE SIZES TO SCALE THE DRAWING

Length is drawn to scale. Tube and flange diameters are drawn in true proportion to one another within each drawing.

Ends

The two ends are independent. Where a flange doesn’t weld natively to your tube we machine an adapter, shown on the drawing.

Complex or Unique Builds

Custom chambers, non-standard geometries, multi-port clusters, convoluted tubing — anything the builder below cannot configure. Describe the project and we will get back to you.

Autogenous Fusion Welds

No filler. Back-purged with high-purity argon, welded on the vacuum side wherever geometry allows.

In-House Design & Fabrication

Engineered, fabricated, and inspected under one roof — no outsourced production welding.

7 Families Flange Standards

CF, KF/QF, ISO-K, ISO-F, ASA/ANSI, JIS and VCR — imperial and metric, including legacy conversions nobody stocks.

FAQ

Vacuum Fabrication Questions

What vacuum levels do you build to?

High vacuum through ultra-high and extreme-high vacuum. At these pressures the chamber itself sets the achievable base pressure, not the pump — so the work goes into weld quality, surface finish, and designing out trapped volumes. Tell us your target base pressure and whether the chamber will be baked, and we will build to it.

Do you work from our drawings?

Yes — build to print is most of what we do. Send the drawing and you get a priced quote with a committed delivery date within 24 hours. We will flag anything in the design that creates an unaccounted-for trapped volume before we quote it, not after we build it.

Which flange standards do you cover?

ConFlat, KF/QF, ISO-K, ISO-F, ASA/ANSI, JIS and VCO/VCR — imperial and metric. Mixed-family converters are standard work here: ConFlat on one end and KF or ISO on the other, or imperial-to-metric adapters for equipment that predates the current convention. If nobody stocks the part you need, that is exactly the part we build.

What if the builder cannot configure what I need?

The configurator covers straight tube converters. Chambers, non-standard geometry, multi-port clusters, convoluted tubing and full weldments all go through the vacuum project form below — describe the geometry, material, pressure regime and timeline and we will come back with a quote.
