Materials Needed:

Coupling Alignment Gage (CA-9001) Calipers



Contact points (3)



Paper clip or Piano Wire

Marker Scale or Ruler

1. Use the table at right to determine which

contact points should be installed to inspect

the coupling.

IMPORTANT: API Specification 5B Section

5.1.35 requires proper contact points be used

during the inspection of coupling alignment.

2. Rock the gage forward and seat the moveable

contact point into the thread. Use your index

finger to apply just enough pressure to

maintain the gage’s contact with the thread

flanks.

3. Use a marker to draw a line inside of the

coupling.

NOTE: This line will be used as a timing mark.

4. Use a marker to mark the center of the

coupling.

5. Mark the thread that is 1.500 in. from the

center of the coupling.

IMPORTANT: This mark will be used to properly

position the center of the coupling between the

contact points of the CA-9001 as mandated by

API Specification 5B Section 5.1.35.

6. Place the coupling on a table or surface and

position it on its side.

NOTE: The table or surface needs to have

enough room for the coupling to roll one complete

revolution.

IMPORTANT: Proper Personal Protective

Equipment (PPE) such as steel toed boots should

be worn during the inspection of the coupling to

prevent injuries from falling objects.

7. Position the CA-9001 by placing the two fixed

contact points into the thread groove marked

in Step 5 (1.500 in. from center). Ensure that

all of the contact points are seated in the

proper thread grooves.

8. Zero the gage by adjusting the bezel.

9. Roll the coupling one complete revolution and

make note of the minimum and maximum

indications.

TIP: Roll the coupling by keeping both hands on

the gage and pushing the gage down and

forward.

10. Determine the total sweep by subtracting the

minimum indication from the maximum

indication.

The total sweep of the coupling must not

exceed the maximum sweep value recorded

in the tables found in the Maximum Sweep

Value tables on page 7 & 8.

The maximum sweep values were calculated

using the following equation from API

Specification 5B Section 5.1.35.

where

R= maximum permissible sweep of the

dial gauge indicator;

E= pitch diameter of the coupling where

the contact points on the gauge are

located. This must be calculated for the

coupling being inspected;

A= maximum allowable misalignment in

20 ft. API Specification 5B Section 4.1.10

states that the maximum angular

misalignment shall not exceed ¾” per 20’

of the projected axis for all tubing and

casing sizes.

Maintenance Tips

•Keep all unprotected metal surfaces coated with light oil.

•Avoid dropping the gage or subjecting it to any vibration or impact.

•Keep the gage dry and away from any machine coolant spray.

•Do not force the movement of any of the mechanical parts. The mechanics are designed to

move freely.

•Keep the indicator face clean.
