API 5CT Q125 casing tubing

Q125 Tubing is placed within the casing. It is used to transport oil and gas from the source rock to the wellhead.
Product introduction

API 5CT Q125 Casing 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.
