Pākē nui AISI 1020 P235gh DIN 2448 St 35.8 Seamless Carbon Steel Paipu
ʻO ka wehewehe pōkole:
ʻO ka ASTM A53 he kila kalapona, hoʻohana ʻia e like me ke kila kila a i ʻole no ka paipu haʻahaʻa haʻahaʻa.
ʻO ASTM A53 Standard ka maʻamau maʻamau no nā paipu kila kalapona. ʻO ka paipu kila carbon ka mea nui e pili ana i ka hakina carbon mass ma lalo o 2.11% me ka loaʻa ʻole o nā mea hoʻohui i hoʻohui ʻia o ke kila, me ke kiʻekiʻe o ke kalapona i loko o ke kila kekahi o nā ʻO nā mea koʻikoʻi nui e hoʻololi i kona ikaika o ke kila, piʻi ka paʻakikī, a hoʻemi i ka ductility, ka paʻakikī a me ka hiki ke weld.Ma waho aʻe o ia mea, loaʻa iā ia kahi mea liʻiliʻi o ke silika, manganese, sulfur, phosphorus me ka carbon.Ke hoʻohālikelikeʻia me nāʻano kila'ē aʻe,ʻo ia ka mea mua loa, ka uku haʻahaʻa, ka laulā o ka hana, ka nui loa.He kūpono no ke kaomi inoa PN ≤ 32.0MPa, ka mahana -30-425 ℃ wai, mahu, ea, hydrogen, ammonia, nitrogen a me nā huahana ʻaila, a me nā mea ʻē aʻe.ʻO ka paipu kila kalapona ka mea mua loa e hoʻohana i ka nui loa o nā mea kumu ma ka ʻoihana hou.ʻO nā ʻāina ʻoihana o ka honua, i ka hoʻoikaika ʻana e hoʻonui i ka ikaika kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka hana ʻana i ke kila kila, ʻo ia hoʻi ka nānā nui ʻana i ka hoʻomaikaʻi ʻana i ka maikaʻi a me ka hoʻonui ʻana i ka laulā o nā ʻano a me ka hoʻohana.ʻO ka ʻāpana o ka hana ʻana i ka nui o nā mea hao o nā ʻāina, e like me ka mālama ʻia ma kahi o 80%, ʻaʻole ia i hoʻohana nui ʻia i nā hale, nā alahaka, nā alahao, nā kaʻa, nā moku a me nā ʻano mea hana ʻenehana a pau, akā i ka petrochemical hou. ʻoihana, hoʻomohala kai, ua hoʻohana nui ʻia.
Loaʻa iā mākou i kēia manawa nā mea kūʻai aku o nā limahana maikaʻi loa ma ka hoʻolaha, QC, a me ka hana ʻana me nā ʻano pilikia pilikia i loko o ka ʻōnaehana hanauna no ka hale kūʻai nui Kina AISI 1020 P235gh DIN 2448 St 35.8 Seamless Carbon Steel Pipe, E hoʻokipa mākou i nā mea kūʻai a pau mai ka ʻoihana. ʻelua ma ka home a ma waho e launa pū me ka lima, a e hana i kahi wā e hiki mai ana me ka hui pū.
Loaʻa iā mākou i kēia manawa nā mea kūʻai aku o nā limahana maikaʻi loa ma ka hoʻolaha, QC, a me ka hana ʻana me nā ʻano pilikia pilikia i loko o ka ʻōnaehana hanauna noʻO Kina DIN 2448 St 35.8 Paipu kila kila ʻole a me ka paipu hao ʻole P235gh., Ke koi mau nei mākou i ke kumumanaʻo "ʻO ka maikaʻi a me ka lawelawe ke ola o ka huahana".A hiki i kēia manawa, ua hoʻokuʻu ʻia kā mākou mau hopena i nā ʻāina ʻoi aku ma mua o 20 ma lalo o kā mākou mana koʻikoʻi a me ka lawelawe kiʻekiʻe.

1. Hana: ka paipu ma lalo, ka wai o ka honua, a me ka lawe ʻana i ka wai wela.
2. ʻO ka hana mīkini, nā lima lima, nā ʻāpana mīkini hana, etc.
3. Uila: Hāʻawi kinoea, Hydroelectric mana wai pipeline
4. Anti-static paipu no ka makani mana mea kanu, etc.
Hoʻokaʻawale ʻia ke kaʻina hana hana ʻana i ke kaʻina hana i loko o ka paipu wela a me ke anu.
1. Ke kaʻina hana o ka paipu kila maʻemaʻe ʻole i ʻōwili ʻia: tube billet → hoʻomehana → perforation → ʻekolu-roller/cross-rolling & hoʻomau i ka ʻōwili → de-pipe → sizing → hoʻoluʻu → straightening → hydraulic test → marking → seamless steel pipe me ka leverage ʻike ʻia ka hopena.
2. Ke kaʻina hana o ke anu i huki ʻia i ka seamless steel tubes: tube blank → hoʻomehana → perforation → poʻomanaʻo → annealing → pickling → oiling → mau kaha anu → blank tube → wela → straightening → hydraulic test → marking → storage.
ʻO ka ASTM A53 kahi pahu kila kalapona, hiki ke hoʻohana ʻia e like me ke kila kila a i ʻole no nā paipu haʻahaʻa haʻahaʻa.
ʻO ka ASTM A53 (ASME SA53) paipu kila kalapona kahi kikoʻī e uhi ana i ka ʻeleʻele ʻeleʻele a welded ʻeleʻele a wela i hoʻopaʻa ʻia i ka paipu kila galvanized i NPS 1/8 ″ i NPS 26. ʻO A 53 ka mea i manaʻo ʻia no ke kaomi a me nā noi mechanical a ua ʻae ʻia no ka maʻamau. hoʻohana i ka mahu, ka wai, ke kinoea, a me nā laina ea.
Hele mai ka paipu A53 i ʻekolu ʻano (F, E, S) a me ʻelua mau māka (A, B).
Hana ʻia ʻo A53 Type F me kahi weld i ka umu ahi a i ʻole e loaʻa i kahi weld mau (Papa A wale nō)
Loaʻa iā A53 Type E kahi weld pale uila (Papa A a me B)
ʻO ka A53 Type S he paipu maʻemaʻe ʻole a loaʻa i ka papa A a me B)
ʻO A53 Grade B Seamless kā mākou huahana polar loa ma lalo o kēia kikoʻī a ʻo ka paipu A53 maʻamau ʻelua i hōʻoia ʻia i ka paipu Seamless A106 B.
ʻO ASTM A53 paipu kila maʻemaʻe ʻole he hōʻailona maʻamau ʻAmelika.Pili ʻo A53-F i ka waiwai Q235 o Kina, ʻo A53-A i ka mea Helu 10 o Kina, a ʻo A53-B e pili ana i ka mea Helu 20 o Kina.
Loaʻa iā mākou i kēia manawa nā mea kūʻai aku o nā limahana maikaʻi loa ma ka hoʻolaha, QC, a me ka hana ʻana me nā ʻano pilikia pilikia i loko o ka ʻōnaehana hanauna no ka hale kūʻai nui Kina AISI 1020 P235gh DIN 2448 St 35.8 Seamless Carbon Steel Pipe, E hoʻokipa mākou i nā mea kūʻai a pau mai ka ʻoihana. ʻelua ma ka home a ma waho e launa pū me ka lima, a e hana i kahi wā e hiki mai ana me ka hui pū.
Pākē kūʻai nuiʻO Kina DIN 2448 St 35.8 Paipu kila kila ʻole a me ka paipu hao ʻole P235gh., Ke koi mau nei mākou i ke kumumanaʻo "ʻO ka maikaʻi a me ka lawelawe ke ola o ka huahana".A hiki i kēia manawa, ua hoʻokuʻu ʻia kā mākou mau hopena i nā ʻāina ʻoi aku ma mua o 20 ma lalo o kā mākou mana koʻikoʻi a me ka lawelawe kiʻekiʻe.
