ABSTRACT:
For withdrawing a bundle of pipes from a heat exchanger and for inserting such bundle the required tractive forces should be exerted on the bundle in a direction in line therewith by means of a key. In order to engage the pipe bundle at its front end and to firmly grip it in a manner that hanging through of the pipes is restricted to an admissible value, the gripper comprises a clamp having at least two clamping jaws adapted to engage the outer circumference of a front flange of the bundle of pipes.
