Product introduction

API 5CT J55 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.

J55 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 J55 Casing Tubing Specification

Pipe Casing Sizes, Oilfield Casing Sizes & Casing Drift Sizes
Outer Diameter (Casing Pipe Sizes)	4 1/2"-20", (114.3-508mm)
Standard Casing Sizes	4 1/2"-20", (114.3-508mm)
Thread Type	Buttress thread casing, Long round thread casing, Short round thread casing
Function	It can protect the tubing pipe.

API 5CT J55 Casing Tubing Features

The surface of thread of coupling and API 5CT J55 Casing Tubing should be smooth without any tear, burr or other defects
that may have a negative impact on the strength and close connection.

API 5CT J55 Casing Tubing is offered with a free length range from 8m to 13m on basis of the SY/T6194-96 norm. However,
it is also available no less than 6m length and its quantity should be no more than 20%.

Deformations which mentioned above are not allowed to appear on the outer surface of API 5CT J55 Casing Tubing coupling.

Any deformation such as crease, separation, hairline, crack or scab is not acceptable on both inner and outer surfaces of the product.
All these defects should be completely removed, and the removed depth must not exceed 12.5% of nominal wall thickness.
