REED RG26 Series Roll Groover
Description and Specifications
Description
The REED RG26S Roll Groover is designed to form standard rolled grooves in steel, stainless steel, PVC, and aluminum pipe in 2-6” schedule 10, and 2-3” schedule 40. The REED RG26CU Roll Groover (discontinued) is designed to form standard rolled grooves in 2” to 6” copper tubing.
The groove is formed by a groove roll which is fed into the pipe wall. The pipe is supported by a drive roll, which is relieved to permit pipe wall deformation.
The formed grooves comply with the specifications required for mechanical coupling systems. The only adjustment required is for the depth of the groove.
Designed for ease of use and portability, the RG26 Series Roll Groover provides a practical solution for manual on-site and in-place roll grooving.

Tube/Pipe Preparation
For satisfactory tool operation, the following tube/pipe preparation tips should be carefully observed:

1. Tube/pipe must be square cut. Do not use a cutting torch.
   Note: When adjusting for roll groover depth, the trial groove pipe should not have a large burr protruding inward. Use a suitable tool for deburring the pipe or tubing. After the groove depth has been set, deburring of the pipe is not required.

2. The end of the tube/pipe, both inside and out, should be cleaned of coarse scale, dirt or other materials which might interfere with or damage the grooving rolls or distort the groove. Large weld beads are to be ground to permit smooth rolling operation.

Pipe Set-Up
The RG26 is an orbital roll grooving tool which rotates around a pipe held stationary. The pipe may be held in a pipe vise during grooving. The RG26 also grooves piping in a depressurized, in-place piping system.
Pipe Vise Set-Up
The choice of grooving location in the shop or field should take into account the following factors:

• Pipe handling requirements
• Working space requirements for the tool and pipe
• Anchoring requirements for the pipe vise

Procedure

1. Securely mount pipe vise (chain type) on a secure stand or workbench. Pipe vise should be mounted flush with or overhang the edge of the stand or workbench so, when
   the tool is mounted on the pipe, the tool will rotate freely around the pipe and not be obstructed by the bench or stand.

2. Secure pipe in pipe vise, anchored to hold securely the weight of the tool (21 lbs.) 9.5 kg. Position the pipe to overhang the pipe vise approximately 5 – 12” (127 – 305 mm) so the tool can rotate in an unobstructed manner. (See Fig. 1.)

Groove-In-Place Set-Up
Previously installed piping may be grooved with the RG26, providing the piping is securely supported.
NOTE: Pipe hangers must be able to accommodate the weight of the 21 lb. (9.55 kg) RG26 plus the manual effort to operate the tool (approximately 20 ft.-lb. torque) during
grooving.
WARNING
Piping systems must always be depressurized and drained before attempting disassembly.
Failure to do so could result in serious injury, property damage, joint leakage or joint separation.
Mounting Tool

1. Retract the upper roller fully by turning the brass feed nut counterclockwise.
2. With the hex drive nut down, insert the nose of the body into the pipe end. Push the tool onto the pipe until the pipe end stops rest against the pipe end. (See Fig 2.)
3. Draw rolls together by turning the brass feed nut clockwise. Continue tightening until the grooving rolls are in light, but firm contact with the pipe.

Adjusting Groove Depth

The Depth Stop Collars must be adjusted for each tube/ pipe size or change in wall thickness. Groove diameter, identified as the “C” dimension for each tube/pipe size, is
listed under Standard Roll Groove Specifications – Steel and Other IPS Pipe. For convenience, a “C” Diameter Chart for the most common pipe sizes is also on the tool.

1. Unlock the depth stop collars by turning them in opposite directions until they are separated.

2. Locate the groove depth gauge attached to the tool which is identified with the pipe size to be grooved. Turn the depth stop collar, closest to the trunnion, until the distance between the collar and the top of the trunnion is equal to the groove depth gauge thickness. Use the groove depth gauge like a feeler gauge. (See Figure 3.)

3. Turn the second collar until both are locked firmly against one another, maintaining the gap set with the feeler gauge. Replace the depth gauges back into the holder.

4. Prepare a trial groove by tightening the brass feed nut the recommended turn increment, and then by turning the crank nut clockwise until the roll groover has made
   one full revolution around the pipe. (See Fig. 4.)

5. Continue turning the feed nut and cranking the tool around the pipe. Once the jam nuts rest against the trunnion, continue to crank the tool around for one more revolution. (See Fig. 5.) Note: Trial groove pipe should be deburred for best results. A burr on the inside of the pipe will raise the pipe away from the drive shaft, causing inaccurate set-up adjustment. After proper groove depth has been verified by the trial groove, deburring of the following pipes is not required. See Step 1 of “Tube/Pipe Preparation”

6. After a trial groove is prepared and the tool is removed from the pipe, carefully check the groove diameter (“C” dimension), a charted under Standard Roll Groove Specifications – Steel and Other IPS Pipe, page 8, and Drawn Copper Tubing Groove Specifications, page 9. The “C” dimension is best checked with a pipe tape. It may also be checked with a dial caliper or narrow land micrometer at two locations, 90° apart, around the groove. The average reading must equal the required Groove Diameter.
   CAUTION
   The “C” Dimension (groove diameter) must always conform to specifications under Standard Roll Groove Specifications, page 9, to ensure proper joint performance.
   Failure to do so could result in personal injury, property damage, improper installation, joint leakage or joint failure.

7.  If groove diameter (“C” dimension) is not within tolerance, adjust the depth stop collars to obtain the proper dimension. To adjust for a smaller groove diameter, turn the depth stop collars counterclockwise. To adjust for a bigger groove diameter, turn collars clockwise. A quarter turn either way will change the groove diameter by .017” (.068” per full turn).

8. Prepare another trial groove and check the groove diameter again. Repeat Steps 6 and 7 until groove diameter is within specification.

Grooving Operation

NOTE: REED RG26 tool is designed only for roll grooving tube/pipe of the appropriate sizes. Grooving of tube/pipe other than that recommended may not produce grooves of proper tube/pipe end configuration or groove dimensions necessary for joining.
Before Grooving:

• Review Safety Precautions before operating the tool.
• Check to be certain tube/pipe has been prepared properly as detailed in Tube/Pipe Preparation.
• Check to be certain pipe is properly supported as detailed in Pipe Set-Up.
• Check to be certain the tool is properly mounted on the pipe. See Mounting Tool.
• Check to be certain the depth stop collar is adjusted correctly. See Adjusting Groove Depth.

CAUTION
Keep fingers, clothes, hair and objects other than tube/ pipe away from the rotating tool. Use safety glasses, hardhat and appropriate footwear. Failure to do so could result in personal injury.

1. Advance the feed by turning the feed nut clockwise by the amount show in Table 1. Feed rates for the RG26 vary depending on material and pipe wall thickness.
   Material| Wall Thickness inches/(mm)| Turns of Feed Screw to Advance the Feed
   ---|---|---
   Steel and Stainless Steel| .135 to .216
   (3.43 to 5.49)| 1/4 turn
   .120 to .134
   (3.05 to 3.40)| 1/3 turn
   .065 to .119
   (1.65 to 3.02)| 1/2 turn
   Aluminum  and Copper| .135 to .216
   (3.43 to 5.49)| 1/3 turn
   .120 to .134
   (3.05 to 3.40)| 1/2 turn
   .065 to .119
   (1.65 to 3.02)| 2/3 turn
   PVC| .154 to .258
   (3.91 to 6.55)| 3/4 turn

Table 1 – Feed Rates
Note: Over-tightening (overfeeding) will result in shortened bearing life and other tool damage. Over or under-tightening could result in the tool “walking” off the pipe and eventually becoming disengaged from the pipe.

2. Place the ratcheting crank handle onto the drive hex.
   Crank the drive hex nut clockwise until the tool travels one full turn around the tube/pipe.

3. Advance the feed by turning the brass feed nut clockwise by the amount show in Table 1. Crank the tool another full turn around the pipe.

4. Continue grooving by advancing the feed (Table 1) and cranking the groover around the tube/pipe until the depth stop collar comes in contact with the trunnion. At this
   point, the brass feed nut can no longer be tightened. Crank the tool at least one more full turn around the tube/ pipe after full groove depth is achieved.

5. After dismounting tool from pipe (see below), check groove depth to ensure groove meets groove depth specification. NOTE: Groove Diameter should be correct for the diameter and wall thickness of tube/pipe for which it was set under Groove Diameter Stop Setting procedures. Groove diameter should be checked periodically and adjusted as necessary.

Dismounting The Tool

1. Crank the tool until the drive hex is located in the down position.
2. Turn the feed nut counterclockwise to retract the upper roll arm to the full open position.
3. Lift the tool and remove it from the pipe. (See Fig. 6.)

Maintenance

1. Keep tool clean for best and safest performance.
2. Lubrication:
   a) After approximately eight hours of operation, grease the bearings at the three grease fittings on the tool. Use a No. 2 EP Lithium base grease.
   b) Weekly apply a light oil (SAE 10W-30 or equivalent) to the threads where the feed screw passes through the feed nut. Also, oil should be applied to the shoulder bolts
   which hold the roll arm to the body, the feed screw to the roll arm, and at the trunnion pivots.
