RTJ API Ring Groove measuring Digital Caliper JOINT flange valve seal instrument

FEATURES

RTJ (ring type joint facing) API Ring Groove Digital Calipers, RING JOINT GROOVE measuring instruments, RTJ ring groove measuring instruments, rjt vernier caliper
This special caliper is used to measure the ring groove or ring joint in valve flange and pipe flange.
Denotes API critical dimension, break sharp corner typical, groove dimensions for type "R" and "RX" gaskets, size API 6A, API 3-5m ANSI.
With presetting function, so it is easy for origin-setting.
Can measure the outside and inside diameter of the RTJ and API (Ring Type Joint) ring groove. So you can calculate the pitch diamter by below formula: Preset 20mm before measuring, PCD means pitch circle diameter, PCD=(ID+OD)/2 ; Also this caliper can easy measure actually ID and OD for ring joint. Actually OD=reading+10mm, Actually ID=reading-10mm;
Available with conical and accurate cutting points.
The angle of the jaws/claw:23° 23 degree angle,
octagonal gasket and block ring sealing structure,oval type ring joint gaskets.
For ASME / ANSI B16.5

We searched Ring Groove Measuring.

We are using the Caliper to measure RTJ Test Flanges

For ASME / ANSI B16.5

This for our own workshop use. We use for measuring Ring grooves on API 6A Flanges, Blocks & Adapters etc.,

We are currently using Gage maker & Tool Runner Ball verniers, but we also want some direct reading verniers like yours for direct use by our machinists
