Which standard gives the requirements for oil and gas pipeline systems?

• A. CSA Z662
• B. CSA W59
• C. CAN/CSA S16
• D. CAN/CSA S136

Answer: (A)

CSA Z662 is the standard that provides the requirements for oil and gas pipeline systems. It covers the full scope of pipelines used in the oil and gas industry, including design, materials, fabrication, construction, testing, operation, and maintenance, with safety and reliability built in. This standard is specifically intended for pipeline systems, so it governs the kinds of welds, inspections, and quality controls you'd expect on pipelines.

The other standards address different areas: CSA W59 focuses on welding of structural steel for buildings and other structures; CAN/CSA S16 is for the design of steel structures; CAN/CSA S136 is the Structural Welding Code for steel structures. These are not the standards used to govern oil and gas pipelines, which is why CSA Z662 is the correct choice.
