Petrotrim Services provides complete API design files for valves, chokes, and pressure-containing equipment.
Each file is prepared in accordance with the latest edition of API 6A, as well as applicable sections of API 6X and ASME BPVC.

Our API 6A design packages include:

• Engineering Calculations (wall thickness, pressure containment, sealing force, stem thrust)
   
• Finite Element Analysis (FEA) where required
   
• Material Selection and Specification (API 6A Appendix B compliance)
   
• Detailed Manufacturing Drawings (with tolerances and material callouts)
   
• Assembly Drawings & Bill of Materials
   
• Test Plans (Hydrostatic, gas, PR2 if applicable)
   
• Design Validation Summaries (per API 6X)
   

All design files are formatted for submission to customers, third-party inspectors, or certification bodies (e.g., DNV, ABS, API audits).

Petrotrim Services specializes in the design and manufacture of chokes for extreme service conditions, including high pressure, high temperature, erosive, and corrosive environments.

Our choke solutions are engineered for:

• Pressure ratings up to 20,000 psi
   
• Severe erosive media (sand, solids-laden fluids)
   
• Corrosive fluids (CO₂, H₂S, acid gases)
   
• High-temperature operations (up to API class X/Y)
   

• Needle-and-seat and plug-and-cage configurations
   
• Trim options in Tungsten Carbide, Inconel 625, and Ceramic
   
• Modular design for field serviceability
   
• Compatible with API 6A, NACE MR0175, and API 16C (as applicable)
   

We provide full API 6A design documentation, including:

• Engineering calculations
   
• Assembly and manufacturing drawings
   
• Material traceability
   
• Optional FEA validation for critical components
