Casing and tubing for Sour Oil and Gas Service must have a good anti-SSCC (sulfide stresscorrosion and cracking)
performance in the environment where hydrogen sulfide corrosion exists.

After an indepth study, we has successfullydeveloped tubular goods of the Cr-Mo series for this purpose with good hardenability and tempering stability that when tempering takes places at certain temperatures uniform and fine sorbite structures can be obtained.

Their mechanicalproperties can meet fully the requirements of corresponding grades and their anti-SSC performance is excellent byregulating the chemical composition and adopting different heat treatment  procedures.

Oil Pipe Standard API 5CT Seamless Steel Casing J55/K55/L80/N80/P110/T95/Q125


Characteristics:

1. Materials: The chemical compositions have been carefully determined to provide resistance to sulfide stress corrosion
as well as to insure complete through wall hardening.

2.Heat Treatment: Quenching and Tempering are conducted under rigid temperature control to assure homogeneous
physical properties and microstructures.

3.Micro Structure: These grades exhibit fully tempered martensite which is considered to be the most desirable for
resistance to sulfide stress corrosion cracking.

4. Tensile Properties and Hardness:  Yield Strength is limited within a narrow range and hardness is controlled to within
the predetermined maximum limit.

5. Sulfide Stress Cracking (SSC) Performance: Whole grades are designed for 85% or 90% SMYS in NACE condition.
Excellent SSC resistance has been achieved through rigorous, chemical composition, heat treatment, microstructure,
tensile properties, hardness and so on.


Pipe inspection:

A full length non destructive inspection is performed in accordance with API 5CT for external and internal, longitudinal
and transverse defects with a standard notch depth equal to 5% of the specified wall thickness.
