Temperature Class "Choosing temperature ratings is the ultimate responsibility of the user" … API 6A 19th Edition

Considerations for ordering

Four Criteria for Individual Parts (i.e. valves, hangers, etc.)

•

Equipment is rated for service in a specific temperature range or ranges • Maximum production flowing temperature • Mud circulating temperature? • Minimum seasonal temperature

•

Temperature Classes ? ? • K -75 to 180 F (-60 to 82 C) ? ? • L -50 to 180 F (-46 to 82 C) ? ? • N -50 to 140 F (-46 to 60 C) ? ? • P -20 to 180 F (-29 to 82 C) • R Room Temperature ? ? • S 0 to 140 F (-18 to 60 C) ? ? • T 0 to 180 F (-18 to 82 C) *S or T apply for most standard duty slip casing hangers ? ? • U 0 to 250 F (-18 to 121 C) *U is common for generally available wellheads and valves ? ? • V 35 to 250 F (2 to 121 C) ? ? • X 0 to 350 F (-18 to 180 C) -- ref. Annex G ? ? • Y 0 to 650 F (-18 to 345 C) -- ref. Annex G

•

Combinations of Classes are available: ? ? Examples PU = -20 to 250 F (-29 to 121 C)

1. Temperature Class -- API holds the user responsible for choosing temperature class 2. Material Class -- API holds the user responsible for choosing material class 3. PSL (Product Specification Level) -- API recommends PSL's to the user 4. PR (Performance Requirement) -- API minimum or added optional cycle testing of designs Note: When ordering, please specify at least the first two of the four criteria.
