Torque Retention Arrangement

摘要

A torque retention arrangement for a flange bolt connector for use with pipe. The torque retention arrangement a carrier body and a plurality of springs. The carrier body can include a plurality of spring holes equi-spaced around a circumference. A plurality of springs in a vertical stack can be mounted in each of the plurality of spring holes in the carrier. Each spring is in a convex orientation in a pre-torque condition and is in a planar orientation in a post-torque condition.

主权项

1. A torque retention arrangement comprising:
a carrier having a first side and a second side opposite from and spaced from said first side, said carrier includes a plurality of through spring holes spaced around a circumference; a first set of springs stacked within a first spring hole of said carrier, each of said springs in said first set of springs is aligned in a vertical arrangement for receiving a bolt therethrough, at least one spring in said first set of springs is non-coplanar with said carrier in a pre-torque orientation and all of said springs in said first set of springs are coplanar with said carrier in a loaded and torqued orientation; a second set of springs stacked within a second spring hole of said carrier, each of said springs in said second set of springs is aligned in a vertical arrangement for receiving a bolt therethrough, at least one spring in said second set of springs is non-coplanar with said carrier in a pre-torque orientation and all of said springs in said second set of springs are coplanar with said carrier in a loaded and torqued orientation; and, wherein aligning said springs coplanar with said carrier visually indicates a proper torque force.
