Tablo gwosè aman ak tib API
Jun 02, 2026
Dapre laEspesifikasyon API 5CT(Specifikasyon pou Aman ak Tib),API Aman ak Tibyo kolektivman refere yo kòm Oil Country Tubular Goods (OCTG) epi sèvi kòm eleman kritik pou asire entegrite estriktirèl pui yo ak bay kanal pwodiksyon likid; se bwat prensipalman itilize pou liy twou a, izole fòmasyon ak presyon varye, ak anpeche efondreman twou, pandan y ap tib enstale nan kabin an transpòte lwil oliv ak gaz nan sifas la oswa fasilite piki ak operasyon pwodiksyon.
Yo estanda deyò dyamèt (OD) chenn yo vaste, aktib anjeneral kouvri 1.050 pous (26.7 mm) a 4-1/2 pous (114.3 mm)epiaman ki sòti nan 4-1/2 pous (114.3 mm) jiska 20 pous (508 mm), itilize an konjonksyon avèk divès kalite asye ak koneksyon fil ki baze sou pwofondè byen ak kondisyon jewolojik.

FAQ
Ki sa ki estanda API pou bwat?
Estanda prensipal API pou aman seEspesifikasyon API 5CT(Specifikasyon pou Aman ak Tib).
Se dokiman ki gouvène endistri -lajè ki defini egzijans teknik pou dimansyon, pwopriyete mekanik, klas asye, ak metòd tès pou aman ak tib yo itilize nan pwi lwil oliv ak gaz.
Ki tolerans API pou boîtier?
DapreEspesifikasyon API 5CT, Tolerans fabrikasyon estanda pou bwat yo se:
Dyamèt deyò (OD):+1.00% / -0.50% OD nominal tiyo a.
Epesè mi:Epesè miray minimòm lan pa dwe plis pase12.5% anba aepesè miray nominal la (pa gen okenn limit anwo espesifye pou epesè miray la, depi kondisyon pwa yo satisfè).
Pwa:+6.5% / -3.5% pou chak jwenti endividyèl.
Dwatete:Anjeneral, devyasyon total la pa ta dwe depase0.2%nan longè total tiyo a.
Ki twa gwosè tib komen yo itilize?
Twa gwosè tiyo API ki pi komen yo itilize nan endistri lwil oliv ak gaz yo se:2-3/8 pous(60.3 mm),2-7/8 pous(73.0 mm),3-1/2 pous(88.9 mm).
