A106gr.B mea hana paipu kila maʻemaʻe kūʻai kūʻai pololei
ʻO ASTM A106 ka paipu kila maʻemaʻe ʻole no ka paipu kila maʻamau ʻAmelika, me ka a106-a a me ka a106-b. Ua like ka mua me ka waiwai 10# home, a ua like ka mea hope me ka mea 20# hale. No nā moʻo kila kalapona maʻamau a ʻo ia kekahi o nā mea maʻamau i hoʻohana ʻia. Loaʻa i ka ASTM A106 seamless steel pipe nā kaʻina ʻelua: kiʻi anu a me ka ʻōwili wela. Ma waho aʻe o nā kaʻina hana like ʻole, ʻokoʻa lākou i ka pololei, ka maikaʻi o ka ʻili, ka liʻiliʻi liʻiliʻi, nā waiwai mechanical a me ka hoʻonohonoho hoʻonohonoho. Hoʻohana nui ʻia ia i ka ʻaila, ka ʻoihana kemika, ka paila, ka mana mana, ka moku, ka mīkini hana, kaʻa, ka mokulele, ka aerospace, ka ikehu, ka geology, ke kūkulu ʻana, ka ʻoihana koa a me nā ʻoihana ʻē aʻe.
ʻO ke ʻano helu helu ASTM A106 no ke kaomi ʻana o ka paipu kila seamless
S = 8; ʻO ka P i emi iho ma mua o 17.5MPa paipu kila ʻole, ʻo ia ke kumu palekana o ka paipu kila ʻole, a ʻo ka mānoanoa o ka pā he 3mm,
Pumi ʻae ʻia o ka paipu P = (2)* σ/ S* δ) / D
ʻAuhea: ʻo ka p ke kaomi a ʻo ka mānoanoa o ka pā ʻo δ, He aha ke kaomi kiʻekiʻe o ka paipu kila ʻole?
E σ ka ikaika tensile o ka mea, ua aʻo ʻo Zhan Rongrong ʻo ke anawaena o waho o ka paipu ʻo D;
Mānoanoa pā paipu δ=( P*D) / (2* σ/ S)
ʻAuhea s ka mea palekana;
Ma muli o ka emi o P ma lalo o 7MPa, ua aʻo ʻo Zhan Jirong ua koho ʻia ka s ma ke ʻano he s = 4;
Koho mākou i ka mea palekana e like me s = 6; ʻO ka ikaika tensile o 20 kila he 410mpa, ka mākeke kila, a ʻo ke anawaena o waho o ka paipu he d
ʻO ka paipu kila maʻamau ʻAmelika he ʻāpana kila lōʻihi me ka ʻāpana ʻāwaha a ʻaʻohe ami a puni. ʻO ka paipu kila he ʻāpana hakahaka a hoʻohana nui ʻia e like me ka pipeline no ka lawe ʻana i ka wai. ʻO ka maʻamau maʻamau o ʻAmelika maʻamau, e like me ka pipeline no ka lawe ʻana i ka aila, ke kinoea maoli, ke kinoea, ka wai a me kekahi mau mea paʻa. Ke hoʻohālikelike ʻia me ke kila paʻa e like me ke kila poepoe, ʻo ka paipu kila ke kulou like a me ka ikaika torsional a me ke kaumaha māmā. He kila pauku waiwai. Hoʻohana nui ʻia ia i ka hana ʻana i nā ʻāpana hana a me nā ʻāpana mechanical, e like me ka paipu ʻaila hinu, ka pahu hoʻoili kaʻa, ka pahu kaʻa a me ka scaffold kila i hoʻohana ʻia i ke kūkulu ʻana. Hiki i ka hana ʻana i nā ʻāpana apo me nā paipu kila ke hoʻomaikaʻi i ka hoʻohana ʻana i nā mea waiwai, hoʻomaʻamaʻa i nā kaʻina hana, a mālama i nā mea hana a me nā hola hana, e like me ka rolling bearing apo, Jack lima lima, etc. ua hoʻohana nui ʻia nā paipu kila no ka hana ʻana. ʻO ka paipu kila kekahi mea pono no nā ʻano mea kaua maʻamau. Pono e hana ʻia ka pahu pū a me ka pahu i ka paipu kila. Hiki ke hoʻokaʻawale ʻia ka paipu kila i loko o ka paipu poepoe a me ke ʻano paipu kūikawā e like me nā ʻāpana cross-sectional ʻokoʻa a me ke ʻano. No ka mea, ʻoi aku ka nui o ka ʻāpana pōʻai ma lalo o ke ʻano o ke anapuni like, hiki ke lawe ʻia ka wai e ka paipu pōʻai. Eia kekahi, i ka wā e hoʻokau ʻia ai ka ʻāpana apo i ke kaomi radial i loko a i waho paha, ʻoi aku ka like o ka ikaika. No laila, ʻo ka hapa nui o nā paipu kila he paipu poepoe.
Ma waena o nā paipu kila maʻamau ʻAmelika, ASTM A53 gr. B paipu kila maʻemaʻe no ke kumu nui, ASTM A106 / A53 gr. B chamfered a chamfered kila paipu, bs1387-1985 Pelekania maʻamau ERW kiʻekiʻe alapine welded paipu a me galvanized paipu, ASTM A333 - 40 ℃ - 101 ℃ haʻahaʻa wela seamless kila paipu, ASTM A179 seamless kila paipu no ka wela exchanger a me ka condenser. ʻO ka lōʻihi o ka paipu kila: 5.8m, 6m a hiki i 12m, hiki ke hoʻonui ʻia e like me ka makemake o ka mea hoʻohana.
ʻO ke anawaena o waho o ka huahana he 1 / 2 "- 28", 21.3-711.2mm, a ʻo ka mānoanoa o ka paia he sch30, sch40, STD, XS, sch80, sch160, XXS, a pēlā aku. - ka mālama ʻana i ka corrosion e like me ka mea e pono ai, me nā pāpale paipu plastik ma nā ʻaoʻao ʻelua, chamfering e like me ka mea e pono ai, a me ka nānā ʻana i nā huahana.
