API 5L X42 paipu kila, i kapa ʻia ʻo L290, ua kapa ʻia ʻo ia no kona ikaika haʻahaʻa haʻahaʻa o 42,100 psi (290 MPa).Loaʻa iā X42 ka ikaika tensile haʻahaʻa o 60,200 psi (415 MPa).
X42/L290 pae kila paipu no ka haʻahaʻa papa a ua nui hoʻohana 'ia no nā noi me ka haʻahaʻa kaomi.E like me ka lawe ʻana i ke kinoea kūlanakauhale, nā ʻōnaehana hoʻoili wai, a me nā ʻōnaehana paipu ʻē aʻe i koi ʻole i ka hiki ke lawe i ke kaomi kiʻekiʻe.
Nā pae
Wahi a nā koi hana, ua māhele ʻia nā paipu X42 i ʻelua pae kikoʻī huahana,PSL1 a me PSL2.
PSL1ʻO ia kahi kikoʻī paipu laina papa kumu.Hoʻohana maʻamau ia i nā ʻōnaehana kaʻa maʻamau kahi i emi ʻole ke kūlana kaiapuni.
PSL2he papa kiʻekiʻe loa.Hoʻolālā ʻia ia no nā kūlana koʻikoʻi, e like me nā kaiapuni kiʻekiʻe kiʻekiʻe, a me nā noi paʻakikī a i ʻole corrosive.
ʻO ke koho ʻana i ka pae o ka paipu kila e hoʻohana ai ma muli o nā koi kikoʻī o ka papahana, me ka ʻoihana lawelawe i manaʻo ʻia a me nā pono paʻa.
Ke Kaʻina Hana Paipu kila
ʻO ka hana ʻana o nā paipu kila X42 e uhi i kahi ākea o nā ʻenehana hana e hoʻokō i nā pono ʻenehana a me nā pono kūlohelohe.Mai ka leʻaleʻa a hiki i nā ʻano ʻenehana welding, hāʻawi kēlā me kēia ʻano i kona pono ponoʻī a me nā wahi o ka noi.

ʻO nā pono o ka X42 Grade Steel Tubing
1. Mka ikaika a me ka paʻakikī: X42 paipu kila i ka palena iki o 42,100 psi (290 MPa), e hāʻawi maikaʻi mechanical ikaika oiai e malama pono paakiki e ku i kekahi nui o loko a me waho stresses me ka haʻihaʻi.
2. Maikaʻi weldability: Loaʻa i ka paipu X42 ka weldability maikaʻi, kahi e maʻalahi a ʻoi aku ka maikaʻi o ka hoʻouka a hoʻoponopono.He mea koʻikoʻi kēia hiʻohiʻona no nā papahana pipeline lōʻihi, ka mea maʻamau e koi nui i ka hana wili.
3.He kūpono no nā noi haʻahaʻa a me ka haʻahaʻa: Ma muli o kona ikaika hoʻohua haʻahaʻa, kūpono loa ia no nā noi haʻahaʻa a me nā haʻahaʻa haʻahaʻa e like me ka hoʻouna ʻana i ke kinoea municipal, nā ʻōnaehana hoʻohele wai haʻahaʻa haʻahaʻa, a me nā mea ʻē aʻe.
4.Kūʻai-pono: Hoʻohālikelike ʻia me nā māka kiʻekiʻe (e laʻa me X65, X70, a me nā mea ʻē aʻe), ʻoi aku ka maikaʻi o ka paipu kila X42 ma ke ʻano o ka hana ʻana a me nā kumukūʻai kūʻai.
5. Laulā o ka hoʻohana: Hāʻawi i kahi ākea o nā koho no nā koi papahana like ʻole, me ka PSL1 i kūpono no nā koina kūlana maʻamau a me ka PSL2 kūpono no nā noi kahi e koi ʻia ai ka hana kiʻekiʻe.
6. Hana maʻamau: Ma keʻano he māhele o ka API 5L maʻamau,ʻo ka hana a me ka mana maikaʻi o ka paipu kila X42 e hahai ana i nā kūlanaʻoihana koʻikoʻi, e hōʻoiaʻiʻo ana i kona kūlike a me ka hilinaʻi.
X42 Paipu kila
1. Kaʻaila a me ke kinoea: hoʻohana maʻamau i ka hana ʻana i nā paipu aila a me ka ʻea no nā māla aila a me ke kinoea.Hiki i kēia ʻano paipu kila ke lawe palekana me ka maikaʻi i ka ʻaila ʻaila, ke kinoea maoli a me nā huahana petrochemical ʻē aʻe, kūpono loa no nā ʻōnaehana kaʻa haʻahaʻa.
2. Paipu wai: Hoʻohana ʻia ia i ka lawe ʻana i ka wai a me nā ʻōnaehana hoʻōla wai.Ma muli o kona kūpaʻa maikaʻi ʻana i ka corrosion a me ka ikaika o ke kūkulu ʻana, hiki ke hoʻohana ʻia i nā pipeline hoʻouna nui a me nā lālā, kūpono no ka lako wai o ke kūlanakauhale a me nā ʻōnaehana wai ʻoihana.
3. Hoʻohana hale a me ke kūkulu hale: I ka ʻoihana kūkulu, hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana o nā kākoʻo a me nā papa.ʻO kona ikaika a me ka weldability e lilo ia i mea kūpono no ke kūkulu ʻana i nā alahaka, nā kākoʻo alanui, a me nā mea hana ʻē aʻe.
4. Nā kikowaena uila: Ma ka ʻoihana mana, ʻoi aku ka nui o ka cogeneration a me ka geothermal power station, hoʻohana ʻia ka paipu kila X42 no ka lawe ʻana i ka mahu a me ka wai wela, e kōkua ana i ka mālama pono ʻana i ka hoʻololi ʻana i ka ikehu ma kēia mau kaiapuni.
X42 Paipu Mea Kaulike
1. EN 102082 L290NB: L290 pili i ka liʻiliʻi yield ikaika o 290 MPa.Kū ʻo NB no ka normalized a i ʻole normalized rolled a kūpono ia no nā noi like e like me ka hoʻouna ʻana i ka aila a me ke kinoea.
2.ISO 3183 L290: Ua like loa ka papa L290 o ISO 3183 me ka API 5L X42 ma ke ano o ka haku mele a me na waiwai mechanical.
3. GB/T 9711 L290: ʻO kēia ke kūlana Kina no ka paipu kila pipeline, a ua like ka L290 me ka API 5L X42 ma ke ʻano o ka ikaika hua liʻiliʻi.
4. ASTM A106 Papa B: ʻOiai maʻamau i hoʻohana ʻia no ka paipu kila carbon seamless, hiki ke hoʻohana ʻia ʻo ASTM A106 Grade B ma ke ʻano he ʻokoʻa i ka paipu kila welded i kekahi mau hihia, ʻoi aku hoʻi i nā kaiapuni ʻole.
I ke koho ʻana i kahi mea like, he mea nui e hōʻoia i ka mea i koho ʻia e hoʻokō i nā koi hoʻohui kemika, nā waiwai mechanical, a me nā kūlana kūpono ʻē aʻe no ka noi kikoʻī.Eia kekahi, pono e noʻonoʻo ʻia nā kaʻina hana hana, nā ana hōʻoia maikaʻi, a me ka pono o ke kumukūʻai.
E pili ana iā mākou
Mai kona hoʻokumu ʻana i ka makahiki 2014, ua lilo ʻo Botop Steel i mea hoʻolako alakaʻi i ka paipu kila carbon ma Northern China, i ʻike ʻia no ka lawelawe maikaʻi loa, nā huahana kiʻekiʻe, a me nā hoʻonā piha.
Hāʻawi ka hui i nā ʻano paipu kila carbon a me nā huahana pili,
me ka seamless, ERW, LSAW, a me SSAW paipu kila, a me ka laina piha o na paipu paipu a me na flanges.ʻO kāna mau huahana kūikawā pū kekahi me nā mea kila kiʻekiʻe a me nā kila stainless austenitic, i hoʻokō ʻia e hoʻokō i nā koi o nā papahana pipeline like ʻole.
