Product Description

API-5CT P110 CASING PIPE

 

The P110 API-5CT steel casing pipe is the high grade amongst other grades of steel.  White band is marked on the finished casing to point out the materials. During  petroleum drilling and producing, this pipe is generally used in a variety of complicated territory due to its higher tensile strength and higher yield.

It goes down the deepest into the well among other types. However, the price is comparatively high, as well as  the quantity of usage is comparatively few. P110 casing pipe is mainly used in a particular surroundings and when the drilling depth extends to a particular level.
 

Inspection

Physical properties are checked and each length hydrostatically tested, normally to only 3,000 psi in the plain end (unthreaded) condition. The following are also checked:

• Dimensions
• Weights
• Straightness
• Lengths

Part of this inspection is to drift all lengths.
Despite all the American Petroleum Institute (API) specifications and testing, some tubing defects are still found after delivery; thus, some operators do further inspection.

Inspection Method P110 casing pipe connection types

• Size and surface inspection
• NDT and pressure test and third party certication
• Hydrostatic
• Drifting test
• Physical and chemicail analysis
• Hardness and pressure test.
• Electromagnetic
• Magnetic particle
• Ultrasonic

P110 casing pipe connection types 

• Common use connection BTC, buttress thread marked with BC
• LC: Long round thread
• SC: Short round thread
• Premium connections like other gas tight thread
  Customized connection threads as per client requirement
