API 660 Shell and Tube Heat Exchanger for Oil & Gas
What is API 660?
API 660 is the American Petroleum Institute's standard for shell-and-tube heat exchangers in the oil, gas, and petrochemical industries, specifying design, materials, testing, and inspection requirements to ensure safety and reliability in high-pressure, high-temperature, and corrosive environments. It aligns with ASME BPVC and ISO 16812, mandating robust construction, corrosion-resistant materials (like stainless steel), and strict quality control (including hydrostatic testing and NDE) for critical applications in refineries, gas plants, and offshore platforms. Compliance with API 660 signals industry-proven durability, reducing downtime and operational risks.
