Introduction to square steel pipe

He inoa no ka paipu huinahalike a me ka paipu huinahalike, oia hoi, paipu kila me na aoao like a like ole. Hana ʻia ia me ke kila ʻōwili ʻia ma hope o ke kaʻina hana. ʻO ka mea maʻamau, wehe ʻia ke kila kaulahao, pae ʻia, crimped a welded e hana i ka paipu poepoe, a laila ʻōwili ʻia i loko o kahi paipu huinaha mai ka paipu poepoe, a laila ʻoki ʻia i ka lōʻihi i makemake ʻia.

1. ʻAʻole e ʻoi aku ka ʻae ʻia ʻana o ka mānoanoa o ka pā o ka paipu huinahā ma mua o ka hoʻohui a i ʻole ka liʻiliʻi o 10% o ka mānoanoa o ka paia nominal inā ʻaʻole i ʻoi aku ka mānoanoa o ka pā ma mua o 10mm, hoʻohui a hōʻemi paha i ka 8% o ka mānoanoa o ka pā ke ʻoi aku ka mānoanoa o ka pā. ma mua o 10mm, koe wale no ka mānoanoa o ka paia o nā kihi a me nā wahi weld.

2. ʻO ka lōʻihi hāʻawi maʻamau o ka paipu ʻāpana ʻāpana ʻehā he 4000mm-12000mm, ka nui o 6000mm a me 12000mm. Ua ʻae ʻia ka pahu ʻāpana ʻāpana e hāʻawi i nā huahana lōʻihi pōkole a paʻa ʻole ma lalo o 2000mm, a hiki ke hāʻawi ʻia ma ke ʻano o ka paipu interface, akā e ʻoki ka Demander i ka paipu interface i ka wā e hoʻohana ai. ʻAʻole ʻoi aku ke kaumaha o nā ana pōkole a me nā huahana paʻa ʻole ma mua o 5% o ka nui o ka lawe ʻana. No nā paipu manawa kūhāhā me ke kaumaha o ka manaʻo i ʻoi aku ma mua o 20kg / m, ʻaʻole ia e ʻoi aku ma mua o 10% o ka nui o ka lawe ʻana.

3. ʻAʻole ʻoi aku ka nui o ka piʻo ʻana o ka paipu huinahā like ma mua o 2mm no ka mika, a ʻaʻole ʻoi aku ka nui o ke degere kūlou ma mua o 0.2% o ka lōʻihi.

E like me ke kaʻina hana, ua māhele ʻia nā paipu huinahā i loko o nā paipu kuʻekuʻe wela ʻole, nā paipu kuʻekuʻe liʻiliʻi i huki ʻia i ke anu, nā paipu kuʻekuʻe kiʻekiʻe i hoʻokuʻu ʻia a me nā paipu huinahā welded.

Ua maheleia ka paipu huinahalike welded i

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 - straight welded square pipe a spiral welded square pipe.

Hoʻohui waiwai

Ua maheleia na paipu huinaha i na paipu huinahalike kalapona ma'amau 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. Hoʻokaʻawale ʻia ke kila kila haʻahaʻa i Q345, 16Mn, Q390, St52-3, etc.

Hoʻokaʻawale kūlana hana

Ua maheleia ka paipu huinahalike i ka paipu huinahalike ma'amau o ke aupuni, o ke paipu huinahalike ma'amau o Iapana, o ka paipu huinahalike ma'amau o Beritania, o ka paipu huinahalike ma'amau o Amerika, o ka paipu huinahalike ma'amau o Europa a me ka paipu huinaha ma'amau 'ole e like me ka hana ma'amau.

Hoʻohālikelike ʻano ʻāpana

Hoʻokaʻawale ʻia nā paipu square e like me ke ʻano o ka ʻāpana:

1. Pauku huinaha pauku maʻalahi: paipu huinahalike, paipu ʻahāhā.

2. Pupu huinaha me ka pauku paʻakikī: puʻu huinaha ʻano pua, paipu huinahā hāmama, paipu huinahā ʻāwili a me ka paipu huinaha kūikawā.

Ka hoʻokaʻawale ʻana o ka ʻili

Hoʻokaʻawale ʻia nā paipu square i loko o 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.

E hoʻohana i ka hoʻohālikelike

Hoʻokaʻawale ʻia nā paipu square ma o ka hoʻohana ʻana: nā paipu huinahā no ka hoʻonani ʻana, nā paipu huinahā no nā mea hana mīkini, nā paipu huinahā no ka ʻoihana mīkini, 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.

Papa mānoanoa o ka pā

Hoʻokaʻawale ʻia nā paipu ʻāʻī e like me ka mānoanoa o ka paia: ʻoi aku ka mānoanoa o nā paipu ʻāpana pāpaʻi, nā paipu ʻāpana ʻāpana mānoanoa o ka paia a me nā paipu ʻāpana ʻāpana lahilahi. Loaʻa i kā mākou hale hana ka ʻenehana hana ma ka mākeke, a he akamai loa. Welina mai nā hoaaloha honua e kūkākūkā. E ho'āʻo mākou i ka mea maikaʻi loa e hoʻokō i kāu mau pono like ʻole.
