Nā ʻano hana

ʻAʻole maʻalahi ka hoʻololi ʻana o ka flange butt-weld flange, maikaʻi ka hana hoʻopaʻa ʻana a hoʻohana nui ʻia;
He maʻalahi ka hoʻohana ʻana i ka pilina flange butt-weld a hiki ke kū i ke kaomi ʻano nui;
Loaʻa nā koi rigidity a me nā elasticity kūpono a me ka hoʻololi ʻana i ka hoʻololi ʻana i ka hoʻololi ʻana.ʻO ka mamao ma waena o ka junction welded a me ka ʻili hui he nui, a ʻo ka ʻili hui ka manuahi mai ka deformation wela o ka welding;
I ka manawa like, hoʻohana ʻia ia i ka pipeline no ka lawe ʻana i ka media pipiʻi, flammable a pahū.

Kaʻina Hana Hana

1: Ka hana holoʻokoʻa forging o ka poepoe kila;
2. Hoʻopau huahana forging, ʻokiʻoki a me ka hana ʻana;

ʻO ke kaʻina hana o ka ʻāʻī butt-welding flange i hana ʻia e kā mākou hui i kapa ʻia ʻo die forging, i hana ʻia ma ke kau ʻana i ka blank wela i loko o ka forging die i hoʻopaʻa ʻia ma nā mea hana make;
ʻO ke kaʻina kumu o ka hoʻopaʻa ʻana i ka make Kaʻina hana hoʻoheheʻe: blanking, hoʻomehana, pre-forging, hoʻopaʻa hope, kuʻi, ʻokiʻoki, hoʻomaʻamaʻa, pana peening;
ʻO nā kaʻina hana maʻamau ka hoʻonāukiuki, ke kaha kiʻi ʻana, ke kuʻi ʻana, ke kuʻi a me ka hana ʻana;
ʻO nā mea hana hoʻoheheʻe maʻamau maʻamau, ʻo ia hoʻi ka hāmare die forging, ka mīkini hoʻoheheʻe wela wela, ka mīkini paʻa paʻa a me ka mīkini paʻi.
ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka flange forged, i hana pinepine ʻia e ka make forging, me ka hoʻolālā aniani maikaʻi a me ka ikaika kiʻekiʻe, a ʻoiaʻiʻo, ʻoi aku ka kiʻekiʻe o ke kumukūʻai;
