PROCESS 

PEIE Mud-Gun consists of a Pedestal with a vertical column holding the swiveling Boom. The Boom swivels through a gear train operated by a Hydraulic Motor.

Boom holds the Barrel Unit comprising of Nozzle, [Heat shielded] Barrel, Stroke Indicator, Hydraulic- Cylinders,

Levers and other accessories. During closing, the Mud Gun is brought to tap hole, aligned and clamped by another Hydraulic Cylinder.. 

Then the mud pushed by actuating the pushing Cylinder.

The Mud Gun assembled with Swivel Joint & Hose-less piping system.

Power pack facilitates to operate the hydraulic actuators
