1227/1228 Single Dial Buttress Form Gauge

To purchase – please contact Allen Gauge directly: 412-241-6410

New and Improved. Used to check tooth thickness at the pitch line on external and internal buttress casing. The new reduced size and smooth operation make it easy to check couplings.

1227- Single Dial Gauge 4 1/2″-13 3/8″

1228- Single Dial Gauge 16″ and Larger

1227

Gauge Type: Single Dial Buttress Form Gauge
Thread Type: Buttress Casing 4-Ω~13 3/8″
Dial Type: 0~5~0, Balanced
Graduation: 0.0005″
Dial Travel: 0.020″

Description: The 1227 is a thread form gauge used to check the tooth thickness of either External or Internal API Buttress Casing in sizes from 4-Ω~13 3/8″. It utilizes an anvil with a fixed pin locator on the 10 Degree flank while the moveable point contacts pitch line of the 3 Degree flank for accurate readings. Product error is determined by first and “zeroing” the indicator on a setting standard. Due to the differences in thread form, a 1225-A Setting Standard is required for External threads and a 1224-A is needed for Internal threads. The measurement taken then indicates the deviation from the API Nominal.

1228

Gauge Type: Single Dial Buttress Form Gauge
Thread Type: Buttress Casing 16~20″
Dial Type: 0~5~0, Balanced
Graduation: 0.0005″
Dial Travel: 0.020″

Description: The 1228 is a thread form gauge used to check the tooth thickness of either External or Internal API Buttress Casing in sizes from 16~20″. It utilizes an anvil with a fixed pin locator on the 10 Degree flank while the moveable point contacts pitch line of the 3 Degree flank for accurate readings. Product error is determined by first and “zeroing” the indicator on a setting standard. Due to the differences in thread form, a 1225-B Setting Standard is required for External threads and a 1224-B is needed for Internal threads. The measurement taken then indicates the deviation from the API Nominal.

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.
