"A" Dimension- The "A" dimension, or the distance from the pipe end to the groove, identifies the gasket seating area. This area must be free from indentations, projections (including weld seams), and roll marks from the pipe end to the groove to ensure a leak-tight seal. All foreign material, such as loose paint, scale, oil, grease, chips, rust, and dirt must be removed.
"B" Dimension- The "B" dimension, or groove width, controls expansion, contraction, and angular deflection of flexible couplings by the distance it is located from the pipe and its width in relation to the coupling housings’ "key" width. The bottom of the groove must be free of all foreign material, such as dirt, chips, rust, and scale that may interfere with proper coupling assembly.
"D" Dimension- The "D" dimension is the normal depth of the groove and is a reference for a "trial groove" only. Variations in pipe OD affect this dimension and must be altered, if necessary, to keep the "C" dimension within tolerance. The groove diameter must conform to the "C" dimension described above.
2.Power-Driven Application
Step 1: Install the handle (Connecting rod) on both sides and fix them with small found nut. |  |
Step 2: Insert the connecting pipe on the main shaft and fix it with screw. |  |
Step 3: Mounts TWG-11A on TUWEI 1T50 Power Drive or RIDGID 300 Power Drive, fix it with fore chuck. |  |
