ʻO ke kila kalapona i ka wiliwili ʻana i ke poʻo
ʻO ka kuʻekuʻe kuʻekuʻe he kila i hoʻopaʻa ʻia a i ʻole kuʻekuʻe lima, ʻo kona ʻano pili e wili pololei i ka kuʻekuʻe a me ka paipu kila.
ʻO nā kūlana hana nui no nā kuʻekuʻe kuʻekuʻe he GB / T13401-2005, GB / T12459-2005, ASME B16.9, SH3409, HG / T21635, HG / T21631, SY / T0510, GB / T10752-199.
Hoʻokaʻawale ʻana i ke poʻo kuʻi kuʻi
(1) Hoʻokaʻawale ʻia ka piko welding e like me kona radius o curvature, hiki ke hoʻokaʻawale ʻia i ka radius lōʻihi a me ka radius pōkole. Ua like ka radius o ka curvature o ka radius lōʻihi me ka 1.5 manawa o ke anawaena o waho o ka paipu, ʻo ia hoʻi R=1.5D. Ua like ka radius o ka curvature o ka radius pōkole me ke anawaena o waho o ka paipu, ʻo ia hoʻi R=1D. Aia ʻo D ke anawaena o ka kuʻekuʻe kuʻekuʻe kuʻekuʻe a ʻo R ka radius o ka curvature. Inā ʻaʻohe wehewehe kikoʻī, hoʻohana maʻamau ka kuʻekuʻe 1.5D.
(2) Ma ka pae kaomi, aia ma kahi o 17 paipu, e like me ʻAmelika Hui Pū ʻIa, me: Sch 5s, Sch10s, Sch 10, Sch 20, Sch 30, Sch40s, STD, Sch 40, Sch 60, Sch80s, XS; ʻO Sch 80, Sch100, Sch120, Sch140, Sch160, XXS, ʻo STD a me XS ka mea maʻamau.
(3) Wahi a ka Angle o ka kuʻekuʻe, aia he 45 degere o ka kuʻekuʻe kuʻekuʻe, 90 degere o ka kuʻekuʻe kuʻekuʻe a me ka 180 degere o ka kuʻekuʻe kuʻekuʻe a me nā kihi ʻē aʻe.
(4) ʻO nā mea: ke kila kalapona, ke kila kila a me ke kila kila.
ʻO ka pōmaikaʻi piʻo kila carbon
1, ʻaʻole pono i ka paipu billet e like me ka mea maka, a hiki ke mālama i ke kumukūʻai o nā lako paipu a me ka ʻōpala, i ka manawa like hiki ke loaʻa i kekahi anawaena nui a me ka mānoanoa o ka paia o ke kuʻe lima kila.
2. ʻO ka billet ka pā pālahalaha a i ʻole ka curved surface, no laila ua maʻalahi ka ʻoki ʻana, maʻalahi ka pololei e hōʻoia, a ʻoi aku ka maʻalahi o ka hui a me ka wili.
3, ʻaʻole pono i nā lako kūikawā, kūpono loa no ka hoʻoili ʻana i ka pūnaewele o ka kuʻe lima kila kalapona.
4, kūpono ke kuʻekuʻe lima kalapona no ka ʻaila, kemika, hydropower, kūkulu ʻana a me ka ʻōnaehana ʻoihana paila.
Nā huahana pale: kalapona kila i ka wiliwili ʻana i ke poʻo, Kina kalapona kila i ka wiliwili ʻana i ke poʻo poʻo, nā mea hoʻolako, hale hana
