The CCUS Corrosion Paradox: Defining the Limits of SteelAs the global energy sector pivots toward Carbon Capture, Utilization, and Storage (CCUS), the metallurgical conversation often focuses erroneously on long-distance transport pipelines. While standard Carbon Steel or API 5L X65 suffices for dry

QUICK DEFINITION: X65 PSL2 LINE PIPEAPI 5L X65 PSL2 is a high-yield carbon steel line pipe used for high-pressure oil and gas transmission. Governed by API 5L and ISO 3183 standards, it balances high strength (65,000 psi yield) with good weldability. It fails primarily in sour service environments (

QUICK DEFINITION: X65 PSL2 LINE PIPEX65 PSL2 is a high-yield (minimum 65,000 psi / 450 MPa) carbon steel line pipe governed by API 5L AND ISO 3183 standards. It is the primary material for high-pressure oil and gas transmission pipelines requiring fracture toughness. It is NOT SUITABLE FOR SOUR SER

QUICK DEFINITION: X65 PSL2 LINE PIPEX65 PSL2 is a high-yield (65,000 psi / 450 MPa) carbon steel line pipe governed by the API 5L / ISO 3183specifications. It is the primary material for high-pressure OIL AND GAS TRANSMISSION PIPELINESrequiring defined fracture toughness. It fails via HYDROGEN CRACK

QUICK DEFINITION: 9CR-1MO BOILER TUBE9Cr-1Mo-V (Grade P91/T91) is a Creep Strength Enhanced Ferritic (CSEF) steel governed by ASTM A335/A213and ASME SA335standards. Used in high-temperature steam piping and headers (up to 600°C), it allows for thinner walls than P22 but is prone to catastrophic TYPE

QUICK DEFINITION: 9CR-1MO BOILER TUBE9Cr-1Mo-V (Grade P91/T91) is a Creep Strength Enhanced Ferritic (CSEF) steel governed by ASTM A335 / ASME SA335. It is used in high-temperature steam headers and reheat piping (up to 600°C) to allow for thinner walls than P22. It fails catastrophically via TYPE I
