API 5ct k55 paipu pahu kila maʻemaʻe

API-5CT K55 oilfield casing paipu ua like loa me J55, aole he nui okoa i ka haku mele.
a ʻoi aku ka ikaika, akā ʻoi aku ka kiʻekiʻe o ka ikaika tensile o K55 ma mua o ke kila J55, ʻo K55 / J55 he 655MPa a
517MPa kēlā me kēia.

ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka ʻenekini a me ka wela a me ka pale ʻana i ka māwae ma mua o J55. No ka luawai hana wela,
kūpono ka pahu paʻa K55 ma kahi o ka pahu J55. ʻOi aku ka maikaʻi o ka mea mua i ka wela wela
ma mua o ka hope.

Nānā
Nānā ʻia nā waiwai kino a hoʻāʻo ʻia kēlā me kēia lōʻihi hydrostatically, maʻamau i ka 3,000 psi wale nō ma ke ʻano ākea (unthreaded).
Ua nānā pū ʻia kēia mau mea:
Anana
Kaumaha
Pololei
Nā lōʻihi
ʻO kahi ʻāpana o kēia nānā ʻana ʻo ka ʻauheʻe i nā lōʻihi a pau.
ʻOiai ʻo ka American Petroleum Institute (API) kikoʻī a me ka hoʻāʻo ʻana, ʻike ʻia kekahi mau hemahema paipu ma hope o ka lawe ʻana; pela, kekahi poe hana
e nana hou aku.

ʻAno nānā:
Ka nui a me ka nānā 'ilikai
NDT a me ka ho'āʻo kaomi a me ka palapala hōʻoia ʻaoʻao ʻekolu
Hydrostatic
Hoʻāʻo ʻauheʻe
ʻIkepili kino a me kemika
ʻO ka ho'āʻo paʻakikī a me ke kaomi.
