Abstract:
1. A method for stopping oil flowing from an end of a ruptured pipe or other device, comprising the following steps: a. mounting a flange on the end of the ruptured pipe or device, if a flange is not already present; b. providing a gate valve having a flange on its lower end to mate with the flange on the ruptured pipe or device; c. providing a permanently affixed gasket member on the mounting flange of the gate valve; d. lowering the gate valve to a depth of the flowing oil from the ruptured pipe or device; e. providing at least two flexible bolts through opposite openings in the flange of the gate valve; f. while the gate valve is situated adjacent the flowing pipe or device, threading each flexible bolt through two opposite openings in the flange of the ruptured pipe or device; g. placing pulling pressure on lower ends of the two flexible bolts to pull the gate valve from a position adjacent the ruptured pipe or device to a second position where the gasket of the gate valve mounts against a face of the flange of the ruptured pipe or device, while the gate valve is in the open position; h. continuing to hold the gate valve in place by the flexible bolts while inserting permanent bolts in the remaining openings of the mated flanges to secure the gate valve permanently in place; and i. closing the gate valve to stop the flow of oil.
