Product Introduction
Forged alloy steel casing spool with integrated 45° landing shoulder for suspending intermediate and production casing strings. Engineered for onshore and offshore drilling, completion, and long-term production. Compliant with API Spec 6A and NACE MR-0175/ISO 15156.
Key Features- 45° high-load landing shoulder — uniform casing load distribution, prevents body deformation
- Dual-purpose design — drilling phase (wear bushing/test plug) and production (casing suspension)
- Multiple sealing options — P-type, B-type, FS spring-energized, all-metal composite
- Metal-sealed test and grease ports — resists H2S/CO2 corrosion, zero-leakage over long-term service
- API 6B / 6BX studded flanges — top and bottom for multi-stack casing programs
- Forged alloy steel body — full material traceability, heat treated, UT/MT documented
- Sour service qualified — NACE MR-0175 (H2S partial pressure > 0.05 psia)
- PSL 1-4, PR1/PR2 — scalable to project criticality
Product Specifications
Below are standardized technical specifications derived from the original product design, covering structure, sealing, matching parts and structural advantages to support your project selection and engineering review.
Applications
- Drilling — wear bushing protects bore; test plug verifies pressure boundary
- Well Completion — positive isolation between intermediate and production casing
- Production — 45° shoulder carries casing load; side outlets for annulus monitoring
- Sour / HPHT / Injection Wells — metal seals + NACE materials for H2S, CO2, water/gas injection
- FAT report, MTC, GA drawing, ITP available before shipment
