API 6A wellhead equipment must withstand complex mechanical loads generated by casing weight, tubing tension, and pressure forces during well operations. These loads act simultaneously and require robust structural design. Equipment components are engineered to distribute stress evenly while maintaining sealing integrity. Compliance with API 6A ensures load ratings are accurately defi... https://globalsealstech.com/product-category/oil-gas-seals/api-6a-wellhead-equipment-seals/
