ABSTRACT:
A mount is provided for mounting from the above surface end of a well casing or tubing string and the mount defines a vertical passage therethrough. A plurality of mounting sleeves are supported from the mount at points spaced circumferentially about the passage and the sleeves open generally radially into the passage from the outer periphery thereof. A plurality of spray heads are removably supported within the sleeves for directing spray sets of liquid outwardly from the inner ends of the sleeves and the spray jets are communicated with the interior of a manifold construction disposed exteriorly of the mount. The manifold construction includes inlet structure whereby corrosion inhibiting liquid chemicals may be supplied thereto under pressure for discharge from the spray heads. The mount is removably mounted from the above surface end of a well casing or tubing string immediately prior to run in of tubing string sections or rods, a pump and other subsurface equipment whereby the exterior surfaces of such sub-surface equipment may be coated with a corrosion-inhibiting chemical as it is run in an associated well.
