Ka waiwai o ka mea hana paipu kila mānoanoa
ʻO ka ʻokoʻa nui ma waena o ka paipu kila pā mānoanoa a me ka paipu kila pā lahilahi aia i ka mānoanoa o ka paia paipu kila. ʻO ka ʻōlelo maʻamau, ʻo nā paipu kila pā lahilahi he ʻenehana hukihuʻi ʻia, ʻoiai ʻo nā paipu kila mānoanoa he ʻenehana wela. Inā hoʻokaʻawale ʻia e ka ʻāpana ana, ua manaʻo ʻia ʻo ka mānoanoa o ka paia / paipu anawaena e like me 0.05 ka wai wai ma waena o ka paipu kila mānoanoa a me ka paipu hao paia lahilahi, ʻO ka paipu kila lahilahi me ka mānoanoa o ka paia / paipu anawaena ma lalo o 0.05 a me ka paipu kila mānoanoa me ka anawaena oi aku mamua o 0.05. Ma keʻano o ka noi, hoʻohana nuiʻia ka paipu kila lahilahi ma ka paipu. Hoʻohana nui ʻia ka paipu kila pā mānoanoa i nā ʻāpana hakahaka. Hoʻohana ʻia ma ke kaomi ʻana a me nā pipeline koʻikoʻi.
ʻO nā mea maʻamau i hoʻohana ʻia ma Kina: 10#, 20#, 45#, 42CrMo, 36crmo, 40Cr, 20Cr, 15CrMo, 12Cr1MoV, Q235A, Q235B, 0Cr13, 1Cr17, 01Br17, 01Br17, 00Cr17, 00Cr17, 00Cr17, 01Br13, 01, 5cr, 19, 2000, 2009 L290, X42, X46, X70, X80.
I ka wā e wili ai i nā paipu kila mānoanoa, e hoʻomaʻemaʻe mua i ka ʻaila, pena, ka wai, ka ʻōpala, a me nā mea ʻē aʻe ma ka hui welded, a laila hana i nā grooves e like me ka mānoanoa o ka pā. E wehe nui ʻia nā mea mānoanoa a ʻoi aku ka liʻiliʻi o nā mea lahilahi (angle grinder), a laila ʻo ke āpau ma waena o nā huahana, ʻo ia ka mea maʻamau 1-1.5 mau manawa ke anawaena o ke koʻokoʻo kuʻi a i ʻole ka uea kuʻi. Inā wehe ʻia ka ʻāwī i ka nui, hiki ke mālama ʻia i ka liʻiliʻi. E hoʻokō ʻia ka wili ʻana ma kahi liʻiliʻi ma ʻekolu mau wahi. ʻO ka maʻamau, ʻoi aku ka maʻalahi o ka hana ma nā wahi ʻehā. I ka wā e wili ai, pono e hoʻopili ʻia ka hapalua. ʻO ka hoʻomaka ʻana ma kahi o 1 cm ma luna o ka lae lalo, i hiki ke hana ʻia ka hui mai ka ʻaoʻao ʻē aʻe. Inā mānoanoa ka pā paipu kila, pono e hoʻopaʻa ʻia, ʻelua mau papa. Hiki ke wiliʻia ka papaʻelua ma hope o ka hoʻopiliʻiaʻana o ka papa mua i loko o ka pōʻai holoʻokoʻa.
Paʻaʻawaʻawa puʻupuʻu → hoʻomehana → ʻoi aku → ʻekolu ʻōwili keʻa olokaʻa, ʻōwili mau a hoʻokuʻu ʻia paha → ka wehe ʻana i ka paipu → ka nui (a hōʻemi paha) → hoʻoluʻu → hoʻopololei → hoʻāʻo hydrostatic (a i ʻole ka ʻike kīnā) → ka kaha
Inā ʻaʻole ʻoi aku ka mānoanoa o ka pā o ka paipu kila ma mua o 12.5mm, ʻaʻole ʻoi aku ka hoʻoikaika weld ma mua o 3.0mm; Ke ʻoi aku ka mānoanoa o ka pā o ka paipu kila ma mua o 12.5mm, ʻaʻole ʻoi aku ka nui o ka hoʻoikaika weld ma mua o 3.5mm.
ʻO ka paipu kila me ke anawaena o waho i ʻoi aku ma mua o 168.3mm e pololei a i ʻole e like me ka kuhikuhi kuhikuhi i ʻae ʻia e ka mea hoʻolako a me ka mea kūʻai mai.
No nā paipu kila me ke anawaena o waho ma mua o 168.3mm, ʻaʻole e ʻoi aku ka curvature ma mua o 0.2% o ka lōʻihi o ka paipu kila.
No ka paipu kila me ka mānoanoa o ka paia ma mua o 4mm ma ka hopena o ka paipu, hiki ke hana ʻia ka hopena o ka paipu me kahi ʻāpana o 30 ° + 5 ° 0 °, kahi kumu o 1.6mm ± 0.8mm, a ʻoi aku ka liʻiliʻi o ka pae o ka paipu. a i ʻole like me 5mm.
