Pie cut marking sleeves for schedule 10 stainless pipe

Pie cut sleeves sized to fit NPS schedule 10 pipe from 1" to 5". They're built for turbo manifolds, intake pipework and any job where you need a bend angle that off-the-shelf weld elbows don't give you. Each sleeve marks a slice 20 mm at its narrowest, with 15° between its faces, so three slices make a 45° and six make a 90°, and you can stop anywhere in between in 15° steps.

SCH10S is thick enough that a badly placed cut shows up as a step inside the joint and a lot of grinding at fit-up. Marking every slice from the same sleeve keeps the faces matched and the bore smooth.

Which version do I need?

This version fits SCH10S pipe, which is sized by nominal bore (NPS). Its outside diameter doesn't match the number on the label: 1.5" NPS is 48.3 mm OD. If you're working in mandrel exhaust tube sold by outside diameter, you need the OD tube version. The sleeves fit by outside diameter, so they should also suit heavier schedules of the same NPS size.

Using the sleeve

  • Mark two reference lines 180° apart along the pipe and hold the sleeve on with its slots on those lines.
  • Scribe along both edges to mark a slice, then turn the sleeve 180°, butt it up to your last line and mark the next.
  • Cut and deburr, then turn alternate segments 180° to build the bend.
  • To roll the bend into another plane, move the cut round using the notches spaced every 15° round the rim.

Specification

  • Cut angle: 7.5° per edge, 15° per slice
  • Slice: 20 mm at its narrowest point (the inside of the bend)
  • Bend radius: set by the sleeve: 76.4 mm plus half the pipe OD (see table)
