Description: The 1222M Three Dial Gauge is used to check the thread form of API Internal Buttress Casing from 114~508mm. Possible problems that may arise in the thread flanks and tooth width are determined through readings of the three separate dials. Indicator #1 contacts and measures the 10 Degree flank, while Indicators #2 & #3 contact and measure the straight portion of the 3 Degree flank. When used in conjunction with the specific Buttress Segment, incorrect flank angle, flank shave and improper tooth width can be verified. The use of a #1232-D Segment Base is required to properly “zero” your gauge. This gauge is used to determine the discrepancies in the thread form that may require further investigation with the #3285 Allen Portable Optical Comparator in conjunction with castings of the thread form.

Three Dial and Single Dial Gauges

The Three Dial and Single Dial gauges are convenient working gauges for controlling the basic thread form on API buttress casing. Their main role as a quick check of thread angles and tooth width during production help to control the manufacturing process and to evaluate incorrect or worn tooling.
