API 5L PSL2Paipu kila LSAW
Hana ʻia ka paipu kila LSAW me ka metala i loko o ka hale i hana ʻia a hoʻoheheʻe ʻia i loko o ka umu uila, mālama ʻia me nā slags synthetic a hoʻolei ʻia e nā casters mau.ʻO ke kaʻina hana kila i hoʻohana ʻia e hōʻoia i ka hoʻokō ʻana i ke kila maʻemaʻe kemika me ka pili ʻana i ka sulfur a me ka phosphor i loko o ka hāʻawi ʻana i nā waiwai tensile kiʻekiʻe, ductility a me ka corrosion kūpaʻa o nā paipu e hoʻohana ʻia ma nā haʻahaʻa haʻahaʻa i loko o nā ʻano media corrosion.
ʻO ka ʻōwili ʻana me ka mīkini paʻi paʻi a me ka wili mau i hoʻolako ʻia me ka mandrel paʻa e hiki ai ke loaʻa nā ʻae ʻana i ke ana ʻana a hōʻoia i ka nele o ke kino paipu a me nā hemahema o ka ʻili.
I mea e hoʻokō ai i ke kila tensile kiʻekiʻe a me ka ductility e like me kona ʻano i koi ʻia, e hāʻawi ana i ke kūpaʻa corrosion kiʻekiʻe ma nā ʻano media corrosion, mālama ʻia nā paipu i loko o kahi kapuahi hele wāwae computerized.ʻO 70% o nā paipu laina aila e pili ana i ka mālama wela.
Nānā ʻia nā paipu no nā kahe o loko a me waho ma o ka hoʻāʻo ʻole ʻana o ka ultrasonic a me ka electromagnetic inspection.Hoʻopau ka paipu i ka nānā ʻana ma hope o ka hana ʻia ʻana o ka beveling e ka ʻike kīnā magnetic-fluoroscopic.
ʻOiai ʻo ka hana ʻana i nā paipu laina ʻole e hōʻoia i ka hoʻāʻo ʻana i nā waiwai kūʻē i ka corrosion ma o ka hydrogen i hoʻokomo ʻia i ke ʻano hana ma lalo o ka NACE MR 02-84 a me ke ʻano o ka ʻāʻī ʻana o ka sulphide stress ma lalo o NACE MR 01-77.
Api 5l gr.bpaipu lauwili
ʻO ke kumu o ka api 5l gr.b seamless paipu kūpono no ka hoʻohana ʻana i ka lawe ʻana i ke kinoea, ka wai, a me ka ʻaila ma nā ʻoihana ʻaila a me nā ʻoihana kūlohelohe.
