Anba aAPI 5CTspesifikasyon, N80 aman ki disponib nan yon pakèt gwosè endistri estanda, tipikman sòti nan4-1/2 "a 20"nan dyamèt ekstèn (OD).
Gwosè aktyèl ou chwazi a depann de konsepsyon pi a (sifas, entèmedyè, oswa bwat pwodiksyon).

Koneksyon komen (Thread) Kalite
LTC (Long Thread kouple): Long fil wonn. Sa a se estanda ki pi komen pou bwat N80.
BTC (Fidèl Buttress kouple): Itilize pou gwo dyamèt pwi oswa seksyon ki gen gwo chaj rupture.
STC (Short Thread kouple): Kout fil wonn. Tipikman yo itilize pou pi fon ak chaj pi ba yo.
Koneksyon Premium: gaz-koneksyon ki sere yo itilize pou gwo-presyon, devye, oswa pi enpòtan.

FAQ
Ki sa ki se yon tiyo N80?
YonN80 tiyose yon klas espesifik nan bwat asye oswa tib yo itilize nan lwil oliv ak gaz perçage, gouvène pa laAPI 5CTestanda.
Fòs:Li gen yon fòs sede sòti de80,000 a 110,000 psi("80 la" refere a fòs sede minimòm 80 ksi).
De kalite:
N80-1:Nòmalize asye (pi bon mache, pwosesis estanda).
N80-Q:Trempe ak apeze asye (pi wo severite ak fòs).
Aplikasyon:Anjeneral yo itilize li nan pi lwil oliv ak gaz ki gen pwofondè mwayen- kote yo bezwen pi wo rezistans presyon konpare ak klas ki pi ba tankou J55 oswa K55.
Itilizasyon:Li sèvi kòm yon kenbe estriktirèl pou mi yo nan lwil oliv ak gaz pwi (manman) oswa kòm kanal la nan ki lwil oliv / gaz yo pote nan sifas la (tib).
Ki fòs sede N80 aman?
Fòs sede nan bwat N80 se:
Minimòm:80,000 psi (552 MPa)
Maksimòm:110,000 psi (758 MPa)
