API 5CT aman tiyo

Casing se gwo tiyo dyamèt ki reyini epi antre nan yon seksyon ki fèk komanse fouye nan yon twou epi ki tipikman kenbe an plas ak siman. Epi nou bay divès kalite bwat san pwoblèm soti nan 4-1/2''-20'' nan klas H40, J55, K55, N80, L80, C95, P110 elatriye.

a Yo ka ogmante kontni kabòn pou L80 jiska 0.50% maksimòm si pwodwi a lwil oliv etenn. b Kontni molybdène pou Klas C90 Kalite 1 pa gen okenn tolerans minimòm si epesè miray la se mwens pase 17.78 mm. c Kontni kabòn pou R95 ka ogmante jiska 0.55% maksimòm si pwodwi a lwil oliv etenn. d Kontni molybdène pou T95 Tip 1 ka diminye a 0.15% minimòm si epesè miray la se mwens pase 17.78 mm. e Pou klas EW P110, kontni fosfò a dwe 0.020% maksimòm ak kontni souf la dwe 0.010% maksimòm. NL = pa gen limit. Eleman yo montre yo dwe rapòte nan analiz pwodwi.
