Pipe Alignment Fixtures
Internal and external pipe clamps that hold a joint true while it is welded.
Pipe alignment clamps that hold two pipes concentric through the weld, including the purge gap. Without them, the root gap closes on one side and the weld is a repair waiting to happen.

What drives the price of this part
Derived from the callouts on this page. Where a driver is not on the drawing, it is not on this list.
- Tolerance
- Concentricity at 0.5 mm is the tightest callout this family carries. Tightening a callout is a process decision, not a machining decision: below the standard ±0.005 mm the work moves to grinding or jig boring, and the price moves with it.
- Material
- The first material listed, Stainless Steel 304 / 304L, rates 4/10 on our machinability scale at 201 HB. On this shop's scale a harder alloy means slower passes and more tool changes, and that is cycle time the quote has to carry.
- Order size
- Minimum order is 1 piece, so on a first order setup and programming are spread over very few parts and they are most of the price. Repeat orders at the same quantity are cheaper without anything on the drawing changing.
See how cycle time is calculated in the machining time calculator and what else moves a price in the cost driver reference.
How these parts are inspected
Matched to the callouts above and the instruments actually on the floor.
- Coordinate measuring machine (Zeiss CONTURA G2, two machines, GR&R 8.4% on the critical feature)
- Dimensional report against the drawing, with a 100% check on critical features rather than a sample
- Certificate of conformance and the mill certificate with every shipment
The full equipment list, with counts, is on the capability page; the inspection sequence is on quality and inspection.
Questions buyers ask
- Internal or external clamping?
- Internal for high-purity and stainless work, because it leaves the outside clear for the purge and the root. External chain clamps are faster on carbon steel spools.
