Steel Casing
PipesCasing pipes are used for
casing 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. The pipes can be delivered
with metal or composite caps at both
ends for thread protection. |

Casing pipes are
manufactured out of steel are smelted in the
electric furnace, treated with synthetic
slags and cast by continuous casters. The
applied steel making 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.
