Product introduction

API 5CT K55 Casing Tubing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline
after drilling is completed. It is able to bear the pressure produced by the exploitation process. After the outer surface is coated
with a protective layer, the tubing is marked in accordance with the API 5CT standard and strapped with metal belt.

K55 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from
rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and
transaxial pressure placed on it while running downhole.

API 5CT K55 Tubing:
K55 Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead.
