Inspecting used RSC box threads with JSS Pitch Diameter gages allows for an isolated measurement of the connection size, quantifying the change in thread cone interference between the new and used conditions. This method will identify box swell or bell mouthing. Instead of measuring directly on used box threads, people often use an OD Mic […]
On used rotary shouldered connection pins, pin stretch is typically quantified in the field by only inspecting lead. The resulting lead error combined with the effect of worn threads causes pre-mature stand-off inhibiting the use of rings. Instead, use a JSS Pitch Diameter gage to directly measure the change in diameter between the allowable tolerance […]

A coupling is aligned when the axis of each threaded taper cone is properly oriented to the other. If either or both axes are not correctly orientated, the coupling is misaligned and […]
To increase measurement accuracy and reproducibility between taper inspections on a single part, mark a guideline with a felt tip pen along the crests of the threads. Then, add a mark on the thread itself for each desired inspection interval. These lines act as a reference point for placing the taper gage’s contact points between […]

Quantifying misalignment on tubing & casing couplings can be cumbersome. A CA-9001 coupling alignment gage makes it easier. The gage utilizes a three point system, so there is no unnecessary sweeping to find maximum & minimum indications. Instead, lay the coupling on its side, seating the gage into the threads, and then zero the dial. […]
For inspecting larger diameters and excessively long depths, the IT-6000 and the PD-6000 are limited. Use an IT-6001 for inspecting taper on tapered threads with greater than 9″ diameters. For diameters greater than 6″, a PD-6001 will inspect pitch diameter on straight threads and seal grooves. By stacking extension rods, these gages will inspect diameters […]
For Tubing and Casing, properly setting a TH-3002R thread height gage is easy, yet often done incorrectly. The setting standard (1014) has a square-shaped notch and a v-shaped notch. First, use the square-shaped notch, zero the gage. Then, use the v-shaped notch to verify the gage is zeroed. If the gage does not read zero […]
