ASTM A252 Papa 3ʻo ia ka mea maʻamau i hoʻohana ʻia e like me ka paipu paila cylindrical.
ʻAʻole i kaupalena ʻia nā paila paipu kila papa 3 i kahi kaʻina hana kikoʻī a hiki ke hana ʻia me ka hoʻohana ʻana i nā ʻano hana hana paipu like ʻole, meNā SMLS(ʻaʻohe humuhumu),ʻIKE(i hoʻopaʻa ʻia i loko o ke arc), a meEFW(hoʻopili ʻia ka electro-fusion). ʻO kēia maʻalahi e hiki ai ke hoʻololi ʻia i nā pono ʻenekinia like ʻole a me nā hiʻohiʻona noi.
Ma ke ʻano he māka kiʻekiʻe loa ma ke kūlana A52, loaʻa iā ia nā waiwai mechanical maikaʻi loa me ka ikaika hua liʻiliʻi o 310 MPa a me ka ikaika tensile liʻiliʻi o 455 MPa a hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana kūkulu halihali mau loa a i ʻole he pūpū no nā paila sima i hoʻolei ʻia ma kahi.
ʻO kaASTM A252Hoʻokaʻawale ke kūlana i nā paila paipu kila i ʻekolu mau papa e kūpono i nā ʻano hana like ʻole a me nā koi ukana. ʻO nā papa ʻekolu:
Papa 1, Papa 2, a me Papa 3.
Ua hoʻolauna ka ʻoihana i kahi hoʻonohonoho piha o nā lako hana paipu kila JCOE LSAW holomua a me nā lako hoʻāʻo, kūikawā i ka hana ʻana o ka paipu kila LSAW me ka paia mānoanoa, nui ke anawaena me DSAW (kuʻihao arc i hoʻopaʻa ʻia i lalo i ʻelua ʻaoʻao).
ʻO nā kikoʻī huahana:
Anawaena o waho: DN 350 – 1500;
Mānoanoa o ka paia: 8 – 80 mm;
Pono nā paila paipu he ʻaoʻao maʻemaʻe.
E ʻoki ʻia nā wēlau i ke ahi a i ʻole e ʻoki ʻia e ka mīkini a laila e wehe ʻia ke ʻano o ka lua.
I ke ʻano onā wēlau i hoʻopili ʻia, pono ke kihi o ka hopena beveled30 - 35°.
Botop Steelhāʻawi i kahi ākea o nā paipu kila ASTM A52 kiʻekiʻe. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no kāu mau koi.
E hana ʻia ke kila ma o hoʻokahi a ʻoi aku paha o kēia mau kaʻina hana: kapuahi hāmama, oxygen kumu, a i ʻole ka umu uila.
E hana ʻia ʻo A252 e kaʻaʻohe ona pilina, hoʻopaʻa ʻia ke kū'ē uila, hoʻopaʻa ʻia me ka uila, a i ʻolehoʻopili ʻia ka fusionkaʻina hana.
Pono nā hui o nā paila paipu i hoʻopaʻa ʻialōʻihi, ʻūhā helical, a i ʻoleʻūhā helical.
No ka hōʻoia ʻana i ka maikaʻi a me ka hana o nā paila kila, he mea nui e koho i ke kaʻina hana kūpono.
He kūpono ke kaʻina hana LSAW (SAWL) no ka paipu kila nui ke anawaena, pā mānoanoa, ʻoi aku hoʻi i nā papahana kūkulu hale a me nā ʻoihana e pono ai ka hiki ke hāpai i nā ukana kiʻekiʻe a me ke kūkulu ʻana i ke kahua hohonu. Ma muli o kona ikaika kiʻekiʻe, ka hiki ke hāpai i nā ukana, a me ka hiki ke hoʻololi i ka hohonu, hiki iā ia ke hoʻololi i nā ʻano kūlana honua paʻakikī me ka hāʻawi ʻana i nā pono o ke kau wikiwiki a me ka lōʻihi o ka lōʻihi.
JCOEhe hana hana maʻamau ia i ka hana ʻana o ka paipu kila LSAW, nona nā pono o ka pono kiʻekiʻe, ke kūlana kiʻekiʻe, ka mana hana diameter nui, ka pololei o ka dimensional, ka hiki ke hoʻololi, a me ka hoʻokele waiwai, ka mea i lilo ai ia i ka hana hana paipu makemake ʻia i nā papahana ʻenekinia nui.
Pono ke kila e loaʻaʻaʻole iʻoi aku ma mua o 0.050% phosphorous.
ʻO ke kaupalena ʻana i ka nui o ka phosphorus i ke kila, ʻo ia ka hōʻoia ʻana he maikaʻi nā waiwai mechanical o ke kila, ʻoiai ke hoʻohana ʻia no nā hana kūkulu e like me ke kūkulu ʻana i nā pou.
Kōkua kēia palena i ka pale ʻana i ke kila mai ka lilo ʻana i mea palupalu loa i nā mahana haʻahaʻa, no laila e hōʻoiaʻiʻo ana i kona palekana a me ka hilinaʻi i ka hoʻohana ʻana.
No nā ʻano ʻē aʻe o nā mea, ʻaʻohe koi.
ʻO kēia no ka mea ʻo ke kumu nui o nā paipu paila paipu ka hōʻoia ʻana i ka ikaika kūpono o nā paipu a me ke kūpaʻa, ʻo ia nā waiwai koʻikoʻi no ka hoʻohana ʻana i ke kākoʻo ʻana i nā hale.
No nā paipu paila tubular, ʻoi aku ka nui o ka nānā ʻana i nā waiwai mechanical o nā paipu, e like me ka ikaika yield, ka ikaika tensile, a me ka paʻakikī, ʻoiai pili pono kēia mau waiwai i ka hiki ke hāpai i ka ukana a me ke kūpaʻa o ke kūkulu ʻana o nā paila tubular i nā hana maoli.
AHāʻawi ka Papa 2 i nā waiwai liʻiliʻi i helu ʻia:
Inā he waena ka mānoanoa o ka paia i kuhikuhi ʻia i nā mea i hōʻike ʻia ma luna, e hoʻoholo ʻia ka waiwai elongation haʻahaʻa loa penei:
Papa 3: E = 32t + 10.00 [E = 1.25t + 10.00]
E: elongation ma 2 ʻīniha [50.8 mm], %;
t: ka mānoanoa o ka paia i kuhikuhi ʻia, ʻīniha [mm].
Hoʻomaopopo ka maʻamau ASTM A252 Grade 3 i ka palekana a me ka hilinaʻi o nā paila tubular i ka hoʻohana ʻia ma ke kau ʻana i nā koi haʻahaʻa loa no kēia mau waiwai mechanical.
No nā ana o ka paipu i helu ʻole ʻia ma nā papa kaumaha o ka paipu, hiki ke helu ʻia ke kaumaha no kēlā me kēia anakahi lōʻihi me ka hoʻohana ʻana i ke ʻano hana.

Hoʻokumu ʻia nā helu ʻana ma luna nei ma ke kuhiakau ʻana he 7.85 kg/dm³ ka nui o ka paipu kila.
Loaʻa i ka ASTM A252 Papa 3 ka ikaika kiʻekiʻe a me ke kūpaʻa no nā ʻano lepo like ʻole a me nā koi halihali. Hoʻohana pinepine ʻia kēia paipu kila i nā noi aʻe:
1. Nā kahua kūkuluHoʻohana ʻia ka paipu kila ASTM A252 Papa 3 ma ke ʻano he kumu paila i ka hana kahua no nā hale kiʻekiʻe, nā alahaka, a me nā hale nui ʻē aʻe e hāʻawi i ke kākoʻo a me ke kūpaʻa e pono ai.
2. Nā awa a me nā awa kū mokuHoʻohana ʻia kēia mau paipu kila no ke kūkulu ʻana i nā awa a me nā awa e hōʻoia i ka hiki i ke kūkulu ʻana ke kū i ka hopena o nā moku a me ka ʻino ʻana o ke kaiapuni kai. I mea e hoʻonui ai i ke kūpaʻa a me ke kūʻē ʻana i ka pala o nā paipu kila, hoʻopili pinepine ʻia nā uhi e hāʻawi i ka pale hou aku.
3. Nā Hana WaiHoʻohana ʻia ka paipu kila ASTM A252 Papa 3 e hoʻoikaika i nā kapa muliwai a hāʻawi i ka pale ʻana i ke kahe ʻana i ke kūkulu ʻana i nā pā wai, nā loka, a me nā pono wai ʻē aʻe.
4. Nā papahana ikehuMa ka mana makani, nā hale hana aila, a me nā papahana ʻē aʻe o ke kahua ikehu, hoʻohana ʻia kēia mau paipu kila ma ke ʻano he mau kūkulu kākoʻo e hōʻoia i ka hana paʻa o nā lako.
5. Nā hale halihaliHoʻohana ʻia ka paipu kila ASTM A252 Papa 3 no ke kūkulu ʻana i nā alahao, nā alaloa, a me nā ala holo mokulele e hāʻawi i ka hiki ke lawe ukana kūpono a me ke kūpaʻa.
Mai kona hoʻokumu ʻia ʻana i ka makahiki 2014,Botop Steelua lilo i mea hoʻolako alakaʻi o ka paipu kila kalapona ma Northern Kina, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.
Botop SteelHāʻawi ʻia nā ʻano paipu kila kalapona like ʻole a me nā huahana pili, me ka paipu kila seamless, ERW, LSAW, a me SSAW, a me kahi papa inoa piha o nā mea hoʻopili paipu a me nā flanges. Hoʻokomo pū kāna mau huahana kūikawā i nā mea hoʻohuihui kiʻekiʻe a me nā kila kila austenitic, i hana ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
