Hoʻolauna Huahana

ʻO ke kuʻekuʻe paipu kila he mea nui i ka ʻōnaehana pipeline e hoʻololi i ke ala o ka kahe wai.Hoʻohana ʻia ia e hoʻohui i ʻelua paipu me ke anawaena inoa like a ʻokoʻa paha, a hoʻohuli i nā paipu i nā kuhikuhi kikoʻī e like me 45 degere, 90 degere, a me 180 degere.
No ka kuʻekuʻe paipu ʻoihana, ʻo ke ʻano o ka hopena pili ʻo ka kuʻekuʻe wāwae e like me ka maʻamau.Hiki ke wehewehe ʻia ka kuʻi kuʻi ʻana ma ke ʻano he kuʻi kuʻekuʻe, kuʻi kuʻekuʻe a me ka hopena groove.

Nā kikoʻī huahana

1. Hoʻokaʻawale ma ke kuhikuhi
ʻIke mākou i kēlā kuʻekuʻe limahiki ke hoʻokaʻawale ʻia i nā ʻāpana like ʻole e like me ke kuhikuhi wai o ka paipu, e like me 45 ° kuʻekuʻe, 90 ° kuʻekuʻe a me 180 ° kuʻekuʻe, ʻo ia nā kihi maʻamau.No kekahi mau paipu kūikawā, he 60 degere a me 120 degere.
2. Hoʻokaʻawale ʻia e ka mea
Kapa ʻia ke kila kalapona he kila māmā a ʻeleʻele paha.E like me ka ASTM A234 WPB
ʻO ke kila kila ka abbreviation o ke kila kila a me ka ʻakika.ʻO ke kila kūʻē i ka ea, ka mahu, ka wai a me nā mea hoʻoheheʻe palupalu nāwaliwali a i ʻole ka waiwai o ke kila kila, ua kapa ʻia ʻo stainless steel.ʻO nā mea maʻamau304a me 316L
3. He aha ka radius kuʻekuʻe
ʻO ka radius piko pili i ka radius o ka curvature.Inā like ka radius me ke anawaena paipu, ua kapa ʻiakuʻekuʻe lima pōkole, i kapa ʻia ʻo SR elbow, i hoʻohana mau ʻia no nā paipu haʻahaʻa haʻahaʻa a me nā paipu wikiwiki.
Inā ʻoi aku ka nui o ka radius ma mua o ke anawaena paipu a me R ≥ 1.5 anawaena, kapa mākou iā ia ʻo ka radius elbow lōʻihi a i ʻole LR elbow, e pili ana i ke kaomi kiʻekiʻe a me nā paipu kahe kiʻekiʻe.
Inā ʻoi aku ka nui o ka radius ma mua o 1.5D, e kapa ʻia ʻo ia ma ke ʻano he piko, a ʻo ke kuʻekuʻe kuʻekuʻe e hōʻike maʻamau e like me 2d elbow, 3d elbow, etc.
4. ʻAno ʻano
Hoʻokaʻawale ʻia ka kuʻekuʻe i ka kuʻekuʻe like-diameter a me ka kuʻekuʻe liʻiliʻi
ʻO ka kuʻekuʻe kuʻekuʻe anawaena he kuʻekuʻe me ke anawaena like ma nā ʻaoʻao ʻelua, ʻo ia ka mea nui i haku ʻia e ke kino kuʻekuʻe.ʻO kona hiʻohiʻona, ʻo ka paipu e hoʻopili ai i nā ʻāʻī ʻelua o ke ʻano like.Loaʻa i ka kuʻekuʻe e like-diameter kahi hoʻolālā kūpono a me ka manaʻo kūʻokoʻa, hiki ke hoʻokō pololei i ka pilina hoʻokahi manawa me ke anawaena like, pēlā i ke kaʻina hoʻoili waena.
Ua kapa ʻia ka kuʻekuʻe hōʻemi ʻo ka kuʻekuʻe hoʻēmi.He paipu paipu ia e hookui ana i elua paipu me na anawaena okoa.
