# High-pressure bolted sanitary clamp, 2 in (bought part: ratings, no drawing)

> What pressure is a 2 inch high-pressure sanitary clamp rated for?

- Category: Hardware › Sanitary clamp fittings
- Kind: Standard part
- Basis: Makers' published working-pressure ratings for the clamp union; no maker publishes a full dimensioned drawing, so no geometry is drawn here
- Page: https://xemstudio.com/objects/sanitary-high-pressure-clamp/ · JSON: https://xemstudio.com/api/geometry?object=sanitary-high-pressure-clamp · Plain text: https://xemstudio.com/objects/sanitary-high-pressure-clamp/sheet.txt

**Exact dimensions.** Every file is drawn at true size with no printing tolerance. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your printer's or process's clearance before making the part.

## Notes

- A heavy bolted clamp for ISO 2852 / BPE 2 in ferrules, bought as is. Two makers publish the same 2 in rating: 1000 psi (69 bar) working pressure at 70–75 °F and 800 psi (55 bar) at 250 °F (121 °C), as the rating of the clamp union with the clamp tightened as the maker states.
- The gasket is a separate rating: the gasket and the clamp must both be rated above the relief setting of the vessel at their temperature. Helium permeates silicone faster than PTFE; PTFE cold-flows under sustained load and heat.
- On the free-piston generator: five, one on each charged joint (A to E), relief set at 15 bar gauge (218 psi). The generator's assembly keeps 10 mm either side of each joint plane clear out to r 45, and the front (+Y) clear for its bolt: turn every clamp's bolt to the front.

## Questions

**Is there a STEP file?**

No: the makers publish ratings and one dimension, not a drawing; it is a bought part.
