Weight Drill Pipe for Oil Coring
Overview:
ROSCHEN SOUR SERVICE PRODUCTS
For H2S environments Roschen has engineered several products for
drill pipe, Heavy Weight Drill Pipe, Drill Collars and accessories.
These range from the most critical service product, NACE tested
SS-105 meeting the IRP 1.8 specification to our RSCY-105 controlled
yield & hardness products for less critical H2S service. Heavy
Weight Drill Pipe, Drill Collars and accessories can be
manufactured from our unique and proprietary RS 110-SS grade, which
can pass a NACE test at 65% of SMYS.
SS-105 GRADE
ROSCHEN MT SOUR SERVICE
Specially engineered using proprietary steel chemistries and state
of the art quench & temper process to meet the stringent
requirements of IRP 1.8 specification for critical sour drilling
• Designed for service in severe H2S environments
• Excellent resistance to Sulphide Stress Cracking
• Drill pipe body and tool joints tested in accordance to NACE
TM-01-77 Method A
• Superior resistance to H2S through carefully selected steel
chemistries for tube and tool joint as well as highly controlled
manufacturing processes.
RS-CY105 GRADE
ROSCHEN MT SOUR SERVICE
Using the same raw materials and manufacturing process as SS-105
grade, the RS-CY105 will meet the stringent mechanical properties
of the IRP 1.8 specification without the NACE test
• Features the same proprietary steel chemistries as used in the
SS-105 grade
• RS-CY105 is suitable for severe H2S environments with excellent
resistance to Sulphide Stress Cracking
• Shorter manufacturing time than SS-105
