CLAMPING SYSTEM WITH BENDABLE LUGS FOR MUTUAL CONNECTION OF PIPES Russian patent published in 2022 - IPC F16L23/00 

Abstract RU 2780262 C2

FIELD: pipeline construction.

SUBSTANCE: invention relates to a clamping system, which contains yoke (10), which contains rim (12) suitable for clamp around clamping surfaces (18, 20) protruding from pipes. The yoke contains a sequence of bendable pins (22) spaced at an angle, and each pin has free working end (23) protruding axially beyond first edge (13'A) of rim (12) to a sufficient distance allowing manual operations with it. Starting from an initial position, in which pins define minimal diameter (DI) in a rest state, pins are suitable for manual and non-elastic bending in the direction of axis (A) of the rim, defining minimal diameter (DR) in a bending position, which is less than the specified minimal diameter in the rest state.

EFFECT: invention allows for adjustment of a degree of retention in a preset position relatively to a clamping surface of one of pipes, which is need to be clamped.
