Nā kūlana API - he pōkole o ka API American Petroleum Institute, ʻo nā maʻamau API ka mea nui i koi ʻia i ka hana lako, i kekahi manawa me ka hoʻolālā a me nā kikoʻī kaʻina.

API paipu ʻolehe pauku kea hakahaka, aohe humu a poepoe, huinaha, kila huinahalike.Hana ʻia ka ingot kila ʻole me ka ʻūhā capillary tube a paʻa paha, a laila e hana ʻia e ka wela, ʻōwili ʻia a i ʻole ke kāhea anuanu.Seamless hollow pauku, ka nui o na auwai no ka lawe ana i ka wai, kila paipu a me ka paa kila pa, etc. i ka like torsional ikaika i ka kulou ana, mama, he hoʻokele waiwai kea-pauku kila, hoʻohana nui 'ia i ka hana 'ana o ka structural'āpana a me. nā ʻāpana mechanical, e like me ka paipu drill, nā ʻauamo kaʻa, nā papa paikikala a me ke kūkulu ʻana me ka scaffolding kila.

Hoʻokaʻawale pinepine ʻia ka paipu seamless API ma muli o ke ʻano i hana ʻia ai.ʻElua mau ʻano manin o ka hana ʻana i ka paipu seamless api, ke kaha kiʻi anu a me ka hoʻopau ʻana, ʻo ke kiʻi anuanu e pili ana i ke ʻano hana paipu kahi e huki ʻia ai ka paipu, a i ʻole ke ʻano ʻia i ka wela lumi.He maikaʻi kēia ʻano hana no ka hana ʻana i kahi ʻoi aku ka maikaʻi o ka ʻili, ka hoʻomanawanui ʻana, nā paia māmā a i ʻole nā ​​anawaena liʻiliʻi o nā paipu.Hana ʻia ka paipu wela wela me ka hoʻohana ʻole ʻia o ka hoʻopau anu, ʻo ia hoʻi, ua kūkulu ʻia ka paipu seamless i ka wā wela loa ka mea.Hoʻohana mau ʻia kēia mau hana ʻelua.
