304 304L 316L stainless steel pipe China

Seamless Stainless steel well casing pipe

The metal pipe or tube used in drilling well or any underground installation is called casing tube or pipe. Casing pipes are used for casing oil & gas wells. In casing a large diameter pipe is assembled and is inserted into a drilled section of a bore-hole.It prevents contamination of fresh water.It provides stronger upper foundation for dipper drill.Enables smooth bore for installing equipment.Seals high pressure zone surface to ward from getting blown off.Casing pipes manufactured out of steel are smelted in the electric furnace, treated with synthetic slags and cast by continuous casters. This process ensures the achievement of chemically pure steel with reference to sulphur and phosphor contents providing high tensile, ductility and corrosion resistance properties of pipes to be operated at low temperatures in various corrosion media. Pipes are heat-treated in a computerized walking beam furnace. Steel grades and heat treatment regimes applied allow high-strength pipe to be obtained. 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. The pipes can be delivered with metal or composite caps at both ends for thread protection.
