Abstract

Method and apparatus for removing and adapting an accessory in a pressurized pipe without any significant loss of fluid in the pipe, a method characterized in that it comprises the steps of: sealing a service pipe protrusion of the fitting in a pipe compressing the outer walls together and removing unnecessary tubing in front of the service tube; loosen any nut that holds the accessory in the pipe; place the appliance on the service and accessory tube; hold the free end of the flexible tube to the service tube; hold the apparatus on the tube using any appropriate clamping device; grab the tube and turn the flexible tube until the accessory is removed from the tube; close the gate valve to prevent gas from escaping from the pipe hole; remove the flexible tube from the valve body; remove the tube gives service and the accessory of the flexible tube; place a new accessory on the flexible tube; attach the end of the flexible tube to the accessory; hold the free end of the flexible tube to the body of the valve; remove the gate from the gate valve; screw the pipe fitting to the point where it can be hand-tightened; remove the clamping device from both ends of the flexible tube; remove the clamping device from the valve body; remove the appliance from the fitting and the pipeline; and tighten the fitting in the tube in a gas-tight manner using an appropriate tool.
