I. He aha ka meaAPI5L
1. ʻO ke kila paipu API5L-B, like me ka hōʻailona L245 Wuyang Iron a me ke kila, no ka L245 ka moʻo haʻahaʻa metala, kiʻekiʻe ke kumukūʻai, ʻaʻole like ke kumukūʻai o nā mea like ʻole, hoʻohana nui ʻia no nā paipu aila, nā paipu kūlohelohe, a pēlā aku, he paipu wili wai haʻahaʻa haʻahaʻa, ʻaneʻane 20# seamless kāna hana.
2. ʻO ka mea hanaPapa X52 paipu kilaʻO ke kila laina, he ʻano kila me nā koi kūikawā i hoʻohana ʻia no ka lawe ʻana i nā paipu aila a me ke kinoea kūlohelohe. Wahi a ka mānoanoa a me ke kūkulu ʻana ma hope, hiki ke hana ʻia e ka wili wili wela, ka wili wili umu a i ʻole ka wili papa mānoanoa waena a hoʻokumu ʻia i loko o ka paipu kila anawaena nui ma o ka wili wili a i ʻole ka wili wili pololei UOE.
3. Paipu kila humuhumu a welded paha, ʻo ke kūlana maʻamauAPI 5L (paipu paipu) PSL2ʻo ia kekahi o nā māka, ʻo kekahi ʻo PSL1 i ka hoʻohālikelike ʻana, ʻoi aku ke kiʻekiʻe o nā koi PSL2 ma mua o PSL1API ʻo 5L ka kikoʻī paipu pipeline i hoʻokumu ʻia e ka American Petroleum Institute, ʻo B kekahi o nā māka kila pipeline.
II. Kūlana API5L
1. Ma ke kūlana API5L, ʻaʻole e ʻoi aku ka nui o nā hui o ka PIPE kila a me ka PIPE WLD 10" SCH STD API5L ASTM A106 GRB paipu kila seamless ma ka ʻāpana like ma mua o 50% o ka helu o nā paipu. Ma mua o ke kau ʻana, e pulumi a hoʻomaʻemaʻe ka hale paipu i nā lua o ka wili a i ʻole ka ea kiʻekiʻe e wehe i ka scum i loko o nā lua. E hōʻoia i ka puka (ʻaʻole e emi ka puka ma mua o 127cm) e hoʻokō i nā koi a pale i ka pani ʻana o ka lua.
2. Cr:≤025 Nickel Ni:≤030 Copper Cu:≤025 Nā waiwai mechanical: Ka ikaika tensile o sigma b (MPa): 560 (57) a ʻoi aku paha ka ikaika yield sigma s (MPa): 335 (34) a ʻoi aku paha ka elongation delta (%): ka hōʻemi ʻana o ka acuity o ka ʻāpana o 18 bits (%): 45 a ʻoi aku paha ka ikehu hopena Akv (J): 55 a ʻoi aku paha nā waiwai toughness hopena o alpha kv (J/cm2).
3. Uhi ka maʻamau API 5L i nā koi hana o ke kila pipeline, ʻoi aku hoʻi no ka ikaika tensile, ka ikaika hua, ka paʻakikī hopena mahana lumi, ka elongation i ka haki, a pēlā aku. Wahi a nā ʻano kila pipeline, ua māhele ʻia ka API 5L i ka paipu kila maʻamau a me ka paipu kila kūikawā, ma waena o ia mea ua māhele ʻia ka paipu kila maʻamau i ka paipu kila maʻamau a me ka paipu kila ikaika kiʻekiʻe, uhi pū ka maʻamau API 5L i nā koi hana hana o ke kila pipeline.
III, he aha ka mea API5Lgrb
1. He ʻoluʻolu ʻole ka API 5LGRB a i ʻolepaipu kila i hoʻopaʻa ʻia, ʻo ke kūlana maʻamau ʻo API 5L (paipu paipu ʻaila), ʻo PSL2 kekahi o nā pae, ʻo kekahi pae ʻē aʻe ʻo PSL1 i ka hoʻohālikelike ʻana, ʻoi aku ke kiʻekiʻe o nā koi PSL2 ma mua o PSL1. ʻO ka API 5L ka kikoʻī paipu pipeline i hoʻomohala ʻia e ka American Petroleum Institute, ʻo B kahi ʻano kila pipeline.
2.ASME SA517, ASTM A517 ipu kaomi i hoʻopau ʻia a hoʻomaʻemaʻe ʻia ka papa kila kila ikaika kiʻekiʻe ASME SA517/SA517M maʻamau e komo pū ana: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrE, SA517GrQ; ʻO ke kūlana ASTM A517/A517M e komo pū ana: A517GrA,.
3. HoʻolakoAPI 5L PSL2kūlanapaipu kila ʻōwiliʻO GrB-X70 Ke anawaena o waho 219-3650 mm Aloha, ua hana mākou i ka paipu wili no 24 mau makahiki, ke lana nei ko mākou manaʻo e loaʻa ka manawa kūpono e hana pū me ʻoe.
