Hoʻopilikino ʻia nā paipu huinahā pā mānoanoa like ʻole
1. E like me ke kaʻina hana - arc welding square tube, resistance welding square tube (kiʻekiʻe alapine a me haʻahaʻa alapinepine), kinoea kuʻihao huinaha paipu a me ka umu ahi kuʻihao huinaha paipu.
2. E like me ka weld - pololei welded huinahalike paipu a me spiral welded huinahalike paipu.
Ua maheleia na paipu huinaha i na paipu huinaha kalapona kila a me na paipu huinaha haahaa e like me ka mea.
1. Hoʻokaʻawale ʻia ke kila kalapona maʻamau i Q195, Q215, Q235, SS400, 20 # kila, 45 # kila, etc.
2. Hoʻokaʻawaleʻia nā kila kila haʻahaʻa i Q345, 16Mn, Q390, St52-3, etc.
Hoʻokaʻawale kūlana hana
Ua maheleia na paipu huinahalike i na paipu huinahalike ma'amau o ke aupuni, na paipu huinahalike ma'amau o Iapana, na paipu huinahalike ma'amau o Beritania, na paipu huinahalike ma'amau o Amerika, na paipu huinahalike ma'amau o Europa a me na paipu huinahalike ma'amau 'ole e like me ka hana ma'amau.
Hoʻokaʻawale ʻia nā paipu square e like me ke ʻano o ka ʻāpana:
1. Pauku huinaha pauku ma'alahi: paipu huinahalike, paipu huinahalike.
2. Pupu huinaha me ka pauku paʻakikī: puʻu huinaha ʻano pua, paipu huinahā hāmama, paipu huinahā ʻāwili a me ka paipu huinaha kūikawā.
Hoʻokaʻawale ʻia nā paipu square i nā paipu kīhāpai wela, nā paipu square galvanized electro, nā paipu square oiled a me nā paipu square pickled e like me ka mālama ʻana i ka ʻili.
Hoʻokaʻawale ʻia nā paipu square ma ke kumu: nā paipu huinahā no ka hoʻonani ʻana, nā paipu huinahā no nā mea hana mīkini, nā paipu huinahā no ka ʻoihana mechanical, nā paipu huinahā no ka ʻoihana kemika, nā paipu huinahā no ka hale kila, nā paipu huinahā no ka hana moku, nā paipu huinahā no ke kaʻa, nā paipu huinahā no ka nā kaola kila a me nā kolamu, a me nā paipu huinahā no nā hana kūikawā.
Hoʻokaʻawale ʻia nā paipu ʻāʻī e like me ka mānoanoa o ka paia: ʻoi aku ka mānoanoa o nā paipu ʻāpana ʻāpana pāpaʻa, nā paipu ʻāʻī pāpaʻi mānoanoa a me nā paipu ʻāpana ʻāpana lahilahi.
1. Kaʻina hana o ka paipu aniani hoʻomaʻemaʻe
Pipe blank - Inspection - peeling - Inspection - wela - perforation - Pickling - grinding - Lubrication a me ka maloʻo ea - welding poo - anu kiʻi - solid solution treatment - Pickling - pickling and passivation - Inspection - anuanu rolling - degreasing - ʻoki poʻo - maloʻo ea - ka hoʻomaʻamaʻa ʻana i loko - ʻO ka poli ʻana o waho - Nānā - ʻIke - hoʻopau ʻia nā huahana
2. Ke kahe kaʻina hana paipu ʻoihana
Pipe blank - Inspection - peeling - Inspection - wela - perforation - Pickling - wili - Lubrication a me ka hoʻomaloʻo ʻana i ka ea - ke poʻo wili - kiʻi anuanu - lāʻau hoʻonā paʻa - Pickling - pickling passivation - Nānā
3. Welded paipu kaʻina kahe
Uncoiling - leveling - hope shearing and welding - looper - forming - Welding - loko a me waho weld bead removal - pre correction - induction wela wela - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - hope inspection - packaging
4. Kaʻina kahe o ka paipu huinahā ʻole
Ke kila poepoe - pahu blank - Nānā - hoʻomehana - perforation - ka nui - ka'ōwili wela - ke poʻo palahalaha - Nānā - Pickling - spherical annealing - kiʻi anuanu - hoʻokumu - hoʻonohonoho hui - Nānā
