Dimensions and mechanical properties are per API 5L 45th Edition with test pressure calculations per API 5L 10.2.6.5 and design pressure calculations per CFR Title 49 Part 192.
* Stupp tests at 100% SMYS for HFW products and 95% for SAWH products with an additional 5% through end load compensation.
** Resulting maximum operating pressures assume a temperature derating factor of 1.000 (250 degrees Fahrenheit or less).
*** Please contact a Stupp representative for details on non-standard sizes, grades, or test pressures.
