Cut, Deburr, and Prepare Plumbing Pipe

A. Finished-Project Specification

Quantity: the number of copper, PEX, and PVC specimens stated in the controlled cut schedule, each cut to its stated target length, reamed or deburred and chamfered as its material requires, labeled by material, size, target length, actual length, and intended joining method, and dry-fit checked against a compatible test fitting.

B. Pipe Preparation Schedule

Item	Target Condition	Verification Method
Cut schedule review	Materials, sizes, fitting allowances, and tolerances reviewed and recorded before cutting	Written record on worksheet
Tool inspection	Every cutter, shear, saw, reamer, deburring tool, and chamfer tool inspected and functioning	Visual and operational check
Reference marking	Reference end and target length marked with a fine, square reference line on every specimen	Visual check against square or wraparound tool
Copper cutting and reaming	Each copper specimen cut square, reamed, and deburred without thinning or gouging the tube wall	Visual inspection of roundness, square cut, and clean surface
PEX cutting	Each PEX specimen cut square in one controlled action, free of angled cuts, flattening, or kinks	Visual inspection of cut end
PVC cutting and chamfering	Each PVC specimen cut square, deburred, and chamfered as required by the selected fitting system	Visual inspection of cut end and chamfer
Labeling	Every specimen labeled by material, size, target length, actual length, and intended joining method	Visual check of label against worksheet
Dry-fit check	Each specimen inserts into a compatible test fitting without forcing or damaging the prepared surface	Direct dry-fit observation

C. Material Takeoff

• Copper stock: new copper tube in the nominal size and quantity stated in the controlled cut schedule, sufficient for every copper specimen plus the stated waste allowance.
• PEX stock: new PEX tubing in the nominal size and quantity stated in the controlled cut schedule, sufficient for every PEX specimen plus the stated waste allowance.
• PVC stock: new PVC pipe in the nominal size and quantity stated in the controlled cut schedule, sufficient for every PVC specimen plus the stated waste allowance.
• Test fittings: one compatible fitting per material and size for dry-fit checking, reserved for verification only and not used for permanent assembly.
• Labeling supplies: durable labels for every specimen, plus the Pipe Preparation Worksheet.

D. Acceptance Standards

Check	Standard
Copper roundness and square cut	Tube retains its original round cross-section with no visible flattening; cut end is square to the tube centerline
Copper interior and exterior condition	Interior burr removed by reaming without thinning the wall; exterior burr removed without gouging the tube surface
PEX cut condition	Cut end is square, free of angled cuts, flattening, scratches, kinks, contamination, or tool damage
PVC cut and chamfer condition	Cut end is square, interior and exterior burrs removed, and chamfer formed to the depth required by the selected fitting system
Dimensional accuracy	Actual length matches the target length within the tolerance stated in the controlled cut schedule
Labeling	Every specimen labeled with material, size, target length, actual length, and intended joining method before proceeding
Dry-fit check	Specimen inserts fully into the compatible test fitting without forcing, and the prepared surface remains undamaged after the check

E. Cut Schedule Review and Tool Inspection

1. Review the controlled cut schedule, pipe materials, nominal sizes, fitting allowance rules, and accepted tolerances. Record every specimen's material, size, and target length on the Pipe Preparation Worksheet before cutting begins.
2. Confirm that all pipe specimens are new, clean, compatible with the selected fittings, and free of concealed pressure. Reject any specimen stock that does not meet this condition.
3. Inspect each pipe cutter, tubing shear, saw, reamer, deburring tool, chamfer tool, and work-holding device. Confirm each tool operates smoothly and that cutting wheels, blades, and reamer flutes are sharp and undamaged.

F. Reference Marking

1. Establish a reference end and identify whether each target length is pipe-only length or finished assembly length. Record this decision on the worksheet before marking any specimen.

G. Copper Specimen Preparation

1. Measure and mark each copper specimen using a fine, square reference line. Confirm the mark is square to the tube using a square or wraparound layout method.
2. Support the copper tube without crushing or flattening it. Use a work-holding clamp or vise sized for the tube diameter.
3. Cut copper with the approved tubing cutter, tightening incrementally to avoid reducing the tube diameter. Rotate the cutter fully around the tube between each incremental tightening.
4. Ream the copper interior and remove the exterior burr without thinning or gouging the tube wall. Use the reamer and deburring tool specified for the tube size.
5. Check copper roundness, square cut, clean surface, and fitting insertion. Confirm the specimen meets the Acceptance Standards table before labeling.

H. PEX Specimen Preparation

1. Measure and mark each PEX specimen using the required insertion or cut reference. Confirm the mark matches the reference convention established in Step 4.
2. Cut PEX square with the compatible tubing shear in one controlled action. Do not saw or rock the shear through the tubing.
3. Reject PEX with angled cuts, flattened ends, scratches, kinks, contamination, or tool damage. Set aside any rejected specimen and record the defect on the worksheet.

I. PVC Specimen Preparation

1. Measure and mark each PVC specimen using a square wraparound or approved layout method. Confirm the mark is square around the full pipe circumference.
2. Support PVC on both sides of the cut and use the approved ratcheting cutter or fine-tooth saw procedure. Keep the cut aligned with the marked reference line throughout the cut.
3. Remove interior and exterior burrs and form the chamfer required by the selected fitting system. Use the specified chamfer tool and depth.
4. Clean PVC ends without using incompatible chemicals or contaminating the prepared surface. Use only a cleaner approved for the pipe material.

J. Labeling, Dry-Fit Checking, and Error Correction

1. Label every specimen by material, size, target length, actual length, and intended joining method. Complete the label before the specimen leaves the work surface.
2. Dry-check compatible fittings without damaging prepared surfaces. Insert each specimen fully into its test fitting and remove it without forcing or scoring the surface.
3. Record dimensional errors and identify whether they resulted from measurement, fitting allowance, cut angle, tool control, or deburring. Write the identified cause on the worksheet for every specimen outside tolerance.
4. Replace failed specimens and complete the preparation inspection. Confirm every item on the Pipe Preparation Schedule meets its target condition before closing out the project.
