Review fit and service access together
Send a drawing or photos with a scale. When the required measurements are available, we can prepare a CAD drawing or another annotated design for you and TERCC to review together.
What a review drawing covers
The drawing records the equipment, dimensions, intended cover boundary and the places your team needs to reach. We review open questions against a named revision. Material, fabrication feasibility and acceptance checks are agreed before a firm order.

What to send
Send the valve model, side and front photos with a scale, the flange outside diameter and the stem position at full travel. Show which side technicians work from.
What to compare
- Split body jacket
- Consider where the bonnet can remain exposed and the body sections can come away without catching the stem.
- Separate bonnet section
- Consider where the bonnet also needs coverage. Check how the second section opens and whether the packing gland remains accessible.
What to check
Review the cover boundary and strap position together. If a trial fit is agreed, run the handwheel through its full travel, reach the packing gland and remove and refit the cover.
Remove a flange cover in a tight bay
What to send
Send the flange outside diameter, full joint width including projecting studs, adjacent insulation outside diameter and the gap to walls or supports. Mark the side used for bolt work.
What to compare
- Two removable halves
- Consider when each half has a clear removal path and the closures are reachable. Verify both halves can clear the wall and the studs.
- Flexible wrap with a working-side closure
- Consider when there is enough space to pull a flexible wrap around the joint and a single reachable closure simplifies removal.
What to check
Agree the direction of removal and the space needed for bolt work. If a trial fit is agreed, remove the cover and check bolt access, adjacent insulation and any required leak-detection points.
Send us the fit problem
Include the equipment model, normal and peak surface temperatures, quantity, and anything the jacket must clear. For sensitive drawings, agree how to share them before sending files.
