1) ka nānā ʻana i ka geometric pipe kila maʻemaʻe

ʻO ke anawaena paipu kila maʻemaʻe, ka mānoanoa o ka paia a me ka curvature, ka lōʻihi ma ka papa hoʻokolokolo me ka caliper, micrometer, a kūlou i ka wāwae, ka lōʻihi o ka lipine e nānā ʻia.

Hiki ke ho'ohana 'ia ke anawaena o waho, ka mānoanoa o ka paia a me ka lō'ihi (e like me ke anawaena, ka mānoanoa, ka mea ana lō'ihi) i ka ho'ā'o mau.Ma ka hopena o ka makahiki 1980 o ke kenekulia 20, ʻo ka hana ʻana o ka mea kanu hoʻoheheʻe kila maʻemaʻe ma ka pūnaewele maʻamau ma ka pūnaewele ʻokoʻa anawaena, mea ana mānoanoa, ma ka hoʻopau ʻana, ka lōʻihi a me nā mea kaupaona.Pono nō hoʻi e nānā ʻia nā ʻōnaʻi lola paipu ʻole OCTG.

(2) nā paipu kila maʻemaʻe, ka nānā ʻana i waho

Hoʻohana maʻamau ka ʻili o loko a me waho, ʻoi aku ka nui o ka nānā ʻana i ka nānā ʻana, loaʻa pū kekahi Prism reflective no ka nānā ʻana.Kekahi kūikawā-kumuhana seamless paipu kila, i kapaia no ka hoʻohana 'ole-destructive ho'āʻo, e like me Eddy manawa, magnetic flux leakage, kani ultrasonic, mea hoʻomaʻemaʻe mākēneki inspection ma kila ili maikaʻi o loko a me waho nānā.

(3) nānā waiwai mechanical a me ka ʻenehana

I mea e hōʻoia i ka mechanical waiwai o seamless kila paipu e hoʻokō maʻamau koi, pono no ka mechanical waiwai ho'āʻo o seamless kila paipu laʻana.

ʻO nā ho'āʻo mechanical properties e pili ana i ka ikaika tensile, ka ikaika hua, ka elongation, ka hopena, a me nā mea ʻē aʻe. ʻO ka hoʻāʻo flattening no ka hoʻāʻo ʻana e pili ana, ka hoʻāʻo flaring, ka hoʻāʻo hydrostatic, ka hoʻāʻo crimping, ka hoʻāʻo ʻana, ka hoʻāʻo perforation.ʻO kēia mau mea hoʻāʻo e pili ana i nā ʻokoʻa like ʻole a me ka hoʻohana maʻalahi a me ke koho.

(4) ho'āʻo hoʻopauʻole

Hōʻike ka NDT i ka hihia me ka ʻole o ka hōʻino ʻana i ka seamless, kuhikuhi i kā lākou mau hemahema o loko a me ka ʻili.I kēia manawa, ʻo ka hoʻāʻo ʻana i ka leakage magnetic flux, ultrasonic, Eddy a me ka fluorescent magnetic particle inspection, ua hoʻohana nui ʻia i nā paipu kila ʻole i hoʻohana ʻia i ka ʻoihana.Nondestructive hana ho'āʻo ua ulu considerably i loko o nā makahiki i hala iho nei, ua puka mai nei he hologram, ka ultrasonic nä frequency spectrum kālailai o acoustic emission ho'āʻo, kani ultrasonic imaging ho'āʻo, a me ke kiʻekiʻe wela kani ultrasonic ho'āʻo a me nā 'ike loea hou.
