Slotted Liner Casings For Water And Oil Wells
Slotted casing pipes are used for oil and gas wells. Steel casing pipes and tubing are applied to furnishing and installing cased tunnels, where they indicate to pass other utilities or obstructions without open excavation. Steel casing pipes and tube have smooth wall and a minimum yield strength of 35,000 psi. Corrosion-proofing water-based paint is applied on the outside pipe surface to protect against atmospheric corrosion during transportation and storage.
Slotted liners are extensively used in SAGD wells and other thermal applications for its superior structural capabilities to withstand installation loads and operation loads in contrast to other sand control devices.
