Offshore Platform Equipment

Background

Our proprietary High Strength Low Alloy (HSLA) forging materials, have been developed by Taylor Forge Engineered Systems (TFES) for use in high pressure applications requiring high strength, excellent toughness, and good weldability. Taylor Forge's unique HSLA forging materials are intended to be the starting material for components certified to MSS SP-75, CSA Z245.11, ASTM A-694, ISO 15590, and API 6A for grades up to 80ksi yield strength.

Experience

Since 2000, TFES has supplied more than 720 tons of high pressure components using our proprietary materials for customers such as: BP America, Chevron, Shell Deepwater, Petrobras, SBM Atlantia, Wilpro, Williams, and FMC.
