ʻO ka paipu kila i hoʻopaʻa ʻia (RW). He mea nui ia i nā ʻoihana like ʻole, me ka aila a me ke kinoea, ka hoʻomohala ʻana, a me nā wahi ʻohi. ʻIke ʻia kēia ʻano paipu no kona ikaika, kūpono, a me ka lōʻihi. No ka hōʻoiaʻiʻo e hoʻokō nā paipu kila ERW i nā pono o nā noi like ʻole, nā subtleties maʻamau like ʻole e hoʻomalu i kā lākou hana ʻana a me ka maikaʻi.

API 5L:
Ua uhi ʻia ka paipu laina e ka API Specification 5L maʻamau no nā ʻōnaehana kaʻa aila a me ke kinoea. ʻO nā paipu laina kila, me ʻO ka paipu kila i hoʻopaʻa ʻia (RW)., nā mea i kūlike a welded ua uhi ʻia ma kēia ʻāpana. I loko o nā ʻoihana ʻaila a me nā kinoea puhi ahi, hoʻohana pinepine ʻia nā paipu kila API 5L ERW e hoʻoneʻe i ka aila, kinoea, a me nā mea pili ʻē aʻe.
Aia nā māka like ʻole o nā paipu kila API 5L ERW, ʻo ka mea i ʻike nui ʻia ʻo ia ʻo PSL1 a me PSL2 (Item Particular Level). ʻOi aku ka pono o ka PSL2 ma mua o PSL1, e pili ana i nā waiwai mechanical a me ka hoʻāʻo ʻole ʻino. Ua uhi ʻia nā paipu me nā manaʻo o waho e hele ana mai 10.3 mm (0.405 iniha) a i 1422 mm (56 iniha).
ʻO kekahi o nā mea koʻikoʻi o nā paipu kila API 5L ERW ko lākou ikaika kiʻekiʻe a hiki i ke kaumaha, kahi i kūpono ai no ka lawe ʻana i ka ʻaila a me ke kinoea. Hiki ke hoʻololi ʻia ka hoʻololi ʻana a me ka hoʻoulu ʻana o nā wai e kēia mau laina 'e hiki ke hoʻomanawanui i nā haʻalulu kiʻekiʻe o loko a me nā ukana waho.
ASTM A53:
ʻO ASTM A53 ka maʻamau maʻamau no ka pōʻeleʻele, wela wela, welded, uhi ʻia i ka zinc, a me ke kila paipu kūpaʻa. Hoʻopili kēia ʻike i nā laina kūlike me ʻO ka paipu kila i hoʻopaʻa ʻia (RW).. Hoʻohana maʻamau ʻia nā paipu kila ASTM A53 ERW i nā mīkini a me nā noi kaomi e like me ka ea, ka wai, ke kinoea, a me nā laina mahu.
Aia ʻelua mau māka o nā paipu kila ASTM A53 ERW i loaʻa: Nā māka A a me B: Ma muli o ko lākou koi ikaika kiʻekiʻe, hoʻohana pinepine ʻia nā paipu B ma nā noi kaomi. Hoʻopili ka hoʻoholo ʻana i nā kuhi laina ostensible ma waena o NPS 1/8 a me NPS 26, me ka mānoanoa o ka pā ma waena o Timetable 10 a me Timetable 160.
ʻO ka adaptability o nā paipu kila ASTM A53 ERW kekahi o kā lākou pono mua. I ka nānā ʻana i kā lākou mau waiwai mechanical sublime a me ka palekana mai ka wehe ʻana, ua kūpono lākou no ka hoʻohana ʻana i kahi hui ākea o nā hoʻohana. Maikaʻi kēia mau laina no ka hui pū ʻana o nā ʻano hana no ka mea hiki ke hoʻopaʻa ʻia, kau ʻia a paʻi ʻia paha.
ASTM A500:
ʻO ka ASTM A500 kahi kikoʻī maʻamau no ka hoʻoheheʻe ʻia ʻana o ke anuanu a me ka seamless carbon steel structural tubing i nā pōʻai a me nā ʻano. Hoʻopili kēia kikoʻī i nā paipu kila ERW a me nā paipu i hoʻohana ʻia i ke kūkulu ʻana a me nā noi hoʻolālā. ʻIke ʻia nā paipu kila ASTM A500 ERW no ko lākou kiʻekiʻe ikaika-a-kaumaha ratio a hoʻohana mau ʻia i ke kūkulu ʻana i nā papa, nā alahaka, a me nā mea hana ʻē aʻe.
Loaʻa nā paipu kila ASTM A500 ERW ma nā papa ʻehā: Papa A, Papa B, Papa C, a me ka Papa D. Loaʻa i kēlā me kēia papa nā koi kikoʻī no ka hoʻoulu ʻana i ka ikaika a me ka ikaika tensile, me ka Papa D i nā koi ikaika kiʻekiʻe. Hoʻopili ka ʻōlelo kikoʻī i nā ʻano poepoe, ʻāpana, a me nā ʻano ʻāpana me nā ʻano like ʻole.
ʻO kekahi o nā hiʻohiʻona nui o nā paipu kila ASTM A500 ERW ko lākou kūlana maikaʻi loa a me ka weldability. Hana kēia mau waiwai iā lākou i mea kūpono no ka hana ʻana a me ka hui ʻana i nā noi hoʻolālā. ʻO ke kaʻina hana anu i hoʻohana ʻia i ka hana ʻana i kēia mau paipu e hāʻawi pū i ko lākou ikaika kiʻekiʻe a me ka pololei o ka dimensional.
ASTM A252:
ʻO ka ASTM A252 kahi kikoʻī maʻamau no nā puʻu paipu kila welded a seamless. Hoʻopili kēia kikoʻī i nā paipu kila ERW i hoʻohana ʻia i nā puʻu ukana a me nā noi hana ʻē aʻe. ʻIke ʻia nā paipu kila ASTM A252 ERW no ko lākou ikaika kiʻekiʻe a me ka lōʻihi, e kūpono ana iā lākou no ka hoʻohana ʻana i nā kumu, nā hale kai, a me nā papahana ʻenehana kīwila.
Loaʻa nā paipu kila ASTM A252 ERW i ʻekolu mau papa: Papa 1, Papa 2, a me ka Papa 3. Loaʻa i kēlā me kēia papa nā koi kikoʻī no ka hoʻoulu ʻana i ka ikaika a me ka ikaika tensile, me ka Papa 3 i loaʻa nā koi ikaika kiʻekiʻe. Hoʻopili ke kikoʻī i nā paipu me nā anawaena o waho mai ka 8 iniha a 72 iniha.
ʻO kekahi o nā pōmaikaʻi nui o nā paipu kila ASTM A252 ERW ʻo ko lākou hiki ke kū i nā ukana kiʻekiʻe a pale i ka corrosion i nā ʻano kaiapuni. Hiki ke hoʻokuʻu ʻia kēia mau paipu i loko o ka lepo a hoʻokomo ʻia me nā ʻano hana ʻē aʻe, e hāʻawi ana i kahi kumu ikaika a paʻa no nā hale.
ʻO ke kaʻina hana no nā paipu kila ASTM A252 ERW e like me nā paipu ERW ʻē aʻe. Hoʻokumu ʻia ke kaula kila a i ʻole ka pā i ke ʻano tubular, a ua wili ʻia ka hili lōʻihi me ka hoʻohana ʻana i ke kuʻi uila. Ma hope o ke kuʻi ʻana, hiki i nā paipu ke hoʻomaʻamaʻa wela a i ʻole nā kaʻina hana ʻē aʻe e hoʻokō ai i nā pono mechanical pono.
Hoʻopili ʻia nā paipu kila ASTM A252 ERW i nā hōʻike hoʻokele maikaʻi like ʻole, me nā hoʻāʻo ʻana a me nā hoʻāʻo ʻana. Hōʻoia kēia mau hoʻāʻo ʻana i nā paipu i ka ikaika a me nā kikoʻī ductility. Nānā pū ʻia ka weld seam me ka hoʻohana ʻana i nā ʻano hoʻāʻo non-destructive no ka ʻike ʻana i nā hemahema.
ʻAʻole kikoʻī kikoʻī ʻia ka hui kemika o nā paipu kila ASTM A252 ERW, akā aia ka maʻamau i nā koi no nā waiwai mechanical. Hoʻohana maʻamau nā mea hana i nā kemika kila e hiki ai iā lākou ke hoʻokō i kēia mau pono waiwai me ka hōʻoia ʻana i ka weldability maikaʻi a me ka formability.
ʻO ka mea hoʻolako uila welded steel pipe resistance:
No ka poʻe e ʻimi nei i nā Pipes Welded Steel Resistance kiʻekiʻe, kū ka Longma Group ma ke ʻano he mea hoʻolako kaulana. Hāʻawi lākou i kahi laulā o nā paipu kila ERW e kū ana i nā kūlana honua like ʻole, me API 5L, ASTM A53, ASTM A500, ASTM A252, a me ASTM A795.
ʻO ka hoʻokō ʻana o ka Longma Group i ka maikaʻi a me ka mālama ʻana i nā kūlana honua e hōʻoia i kā lākou paipu kila ERW e hoʻokō i nā koi koʻikoʻi o nā ʻoihana like ʻole. Inā makemake ʻoe i nā paipu no ka lawe ʻana i ka aila a me ke kinoea, nā noi hoʻolālā, nā hana kūkulu, a i ʻole nā pūnaewele pale ahi, loaʻa i ka Longma Group nā huahana e kūpono i kāu mau pono.
Inā ʻoe i loko o ka mākeke no nā mea hana ʻo Electric Resistance Welded Steel Pipe, hoʻokipa ka Longma Group i nā nīnau ma info@longma-group.com. Hiki i kā lākou hui o ka poʻe akamai ke hāʻawi i ka ʻike kikoʻī e pili ana i kā lākou huahana a kōkua iā ʻoe e koho i nā paipu kūpono loa no kāu mau koi papahana.
