API 5L, to'liq ism bilanAmerikalik neft instituti 5l spetsifikatsiyasi, Amerika neft instituti (API) tomonidan tashkil etilgan neft va tabiiy gaz sanoatida stubka va tabiiy gaz sanoatida stubka trubkalari uchun standart spetsifikatsiya. 1926 yilda birinchi nashr etilganidan beri ushbu standart jahon miqyosida tan olingan nufuzli standartlardan biriga aylanib, bir nechta qayta ko'rib chiqildi. API 5L not only stipulates basic requirements such as dimensions, material properties, mechanical performance, chemical composition, non-destructive testing, and hydrostatic testing for steel pipes but also categorizes them into multiple grades (eg, X42, X52, X60, X65 up to X120) based on different operating environments and conditions to meet varying pressure and temperature demands for transportation.
Spetsifikatsiya
