ʻO ka paipu paila he ʻano paipu ʻole.ʻO keʻano o ka hanaʻana e like me ka paipu liʻiliʻi, akā aia nā koi koʻikoʻi no keʻano kila i hoʻohanaʻia no ka hanaʻana i ka paipu kila.
ʻO nā waiwai mechanical o ka paipu paila he mea nui ia e hōʻoia i ka hana hope loa (mechanical properties) o ke kila, e hilinaʻi ana i ka hoʻohui kemika a me ka ʻōnaehana mālama wela o ke kila.I ka maʻamau paipu kila, e like me nā koi hoʻohana like ʻole, ka hana tensile (ikaika tensile, ikaika hua a i ʻole ka hopena, elongation), a me nā hōʻailona paʻakikī a me ka paʻakikī, a me ka hana kiʻekiʻe a me ka haʻahaʻa haʻahaʻa e pono ai nā mea hoʻohana.
I ke kaʻina hana o ka paipu kila maʻemaʻe no ka paila, ʻo ka mālama wela ke kaʻina hana nui.He hopena koʻikoʻi ka hoʻomaʻamaʻa wela i ka maikaʻi o loko a me ka maikaʻi o ka ʻili o ka paipu kila maʻemaʻe, ʻo ia ka mea nui no ka hana ʻana i ka paipu kila seamless.
Hoʻohana kā mākou hui i ka mālama wela non-oxidation, ka hana ʻana i nā paipu kila me ka hui metallographic paʻa a me ka maikaʻi o loko a me waho, me ka hoʻohana ʻana i ka eddy current a me ka ultrasonic automatic flaw detection, steel pipe one by one for eddy current flaw detection and ultrasonic flaw detection.Me ke ana mānoanoa kani ultrasonic a me ka oblique flaw detection functions, hiki iā ia ke ʻike pono i nā hemahema i hoʻopaʻa ʻia i loko o ka paipu kila.
