API 5ct k55 irin casing tube

API-5CT K55 paipu casing oilfield jẹ iru pupọ si J55, ko si iyatọ pataki ninu akopọ kemikali
ati agbara ikore, sibẹsibẹ agbara fifẹ ti K55 ga ju irin J55, K55 /J55 jẹ 655MPa ati
517MPa lẹsẹsẹ.

K55 ni o ni dara darí ati ki o gbona rirẹ resistance ati kiraki resistance ju J55. Fun iṣelọpọ igbona daradara,
eru odi K55 casing yẹ dipo J55 casing. Awọn tele ni o ni kan ti o dara gbona rirẹ resistance ohun ini
