carbon steel Rectangular tubing, He ʻano ʻano hollow square cross section light thin-wall steel pipe, ʻike ʻia hoʻi me ke kila refrigeration bend pauku.Hana ʻia ʻo Q235 wela a ʻōwili ʻia i ke kila a i ʻole ka coil plate ma ke ʻano he kumu kumu ma ka hoʻoheheʻe ʻana i ke anuanu a laila e ka wiliwili kiʻekiʻe i hana ʻia i ke ʻano o ka ʻāpana square a me ka nui o ke kila.Ma waho aʻe o ka mānoanoa o ka pā, ʻo ka nui o ke kihi a me ka palahalaha o ka ʻaoʻao o ka paia i ʻōwili ʻia ʻoi aku ka mānoanoa o ka pā pāhaʻi i hiki a i ʻole ke kiʻekiʻe o ke kūpaʻa kuʻi ʻana i ke anuanu.
Hoʻokaʻawale ʻia ʻo Carbon Steel Rectangular Tubing
Pupu kila maʻemaʻe a me ka paipu kila welded (welded pipe) wela olokaʻi seamless huinahā paipu, anuanu huki seamless pāhaʻi paipu, extrusion seamless huinaha paipu, welded square tube.
Ua maheleia ka paipu huinahalike welded i:
1, e like me ke kaʻina hana: arc welding square tube, resistance welding square tube (kiʻekiʻe alapine, low frequency), kinoea kuʻihao huinaha paipu, umu ahi kuʻihao huinaha paipu;
2, e like me ka weld - straight seam welding square pipe, spiral welding square pipe
ʻO ke ʻano ʻike ʻike ʻana o ka pahu hao hao ʻaʻohe
1. He maʻalahi ke pelu ʻana i ka paipu hoʻopunipuni a haʻahaʻa.ʻO ka pelu ʻana he ʻano laina haki i hana ʻia ma ka ʻili o ka paipu ʻehā.Holo pinepine kēia hemahema ma ka lōʻihi lōʻihi o ka huahana.ʻO ke kumu o ka hoʻopiʻi ʻana ma muli o ka ʻimi ʻana i ka hana kiʻekiʻe o nā mea hana hoʻopunipuni a haʻahaʻa, nui ka nui o ke kaomi, hana ʻia ka pepeiao, hoʻopili ʻia ka ʻōwili aʻe, e pohā ka huahana i hoʻopili ʻia ma hope o ke kulou ʻana, a me ka ikaika o ua emi loa ke kila.
2. ʻO ka hiʻohiʻona o ka paipu rectangular hoʻopunipuni pinepine i pockmarked hanana.ʻO nā pockmarks he ʻano kīnā ʻole a ʻaʻole like ʻole ma ka ʻili kila ma muli o ka ʻaʻahu koʻikoʻi o ka ʻōwili ʻōwili.ʻOi aku ka nui o ka groove rolling i ka maʻamau ma muli o ka ʻimi ʻana i ka loaʻa kālā o nā mea hana paipu rectangular shoddy.
3. He ma'alahi ka ili o ka paipu ha'aha'a ha'aha'a e hana i ka scarring.ʻElua kumu :(1).ʻAʻole ʻaʻahu ʻaʻahu ʻaʻohe mea like ʻole o ka pahu pahu rectangular fake, haumia.(2).ʻO nā mea hana Shoddy e alakaʻi i nā mea hana maʻalahi, maʻalahi e pili i ke kila, kēia mau haumia
4. Shoddy mea ili maʻalahi e māwae, ke kumu o kona billet mea adobe, adobe pores, adobe i loko o ka cooling kaʻina hana ma muli o ke kuleana o ka thermal stress, māwae, ma hope o ka olokaʻa aia nā māwae.
5. He maʻalahi ka ʻokiʻoki ʻana i ka paipu rectangular Shoddy, ʻo ke kumu he maʻalahi nā lako hana hana ʻo shoddy rectangular pipe, maʻalahi e hana i ka burr, e ʻoki i ka ʻili kila.ʻO nā ʻōpala hohonu e hoʻemi i ka ikaika o ke kila.
6. Fake rectangular paipu me ka metala luster, malamalama 'ulaʻula a kumu paha no elua helu, kona billet mea adobe.The olokaʻi wela o shoddy mea 'aʻole maʻamau, ko lakou kila wela ua ana visually, no laila, aole hiki ke olokaa e like me ka mea i hoakakaia. austenite wahi, a me ka hana o ke kila maoli hiki ole hiki i ka maʻamau.
7. He lahilahi a haʻahaʻa nā kīʻaha o nā paipu hoʻopunipuni hoʻopunipuni a haʻahaʻa, i ʻike pinepine ʻia me ka ʻoluʻolu ʻole.ʻO ke kumu he nui ka hoʻomanawanui maikaʻi ʻole o ka mea hana a me ke kaomi o nā laina mua o nā huahana i hoʻopau ʻia
8. He oval ka pauku kea o ka paipu rectangular hoopunipuni, o ke kumu o ka mea hana i mea e hoola ai i na mea waiwai, ua nui ke kaomi o ka wili hoopau imua o na mea elua, ua emi loa ka ikaika o keia rebar, aka. ʻaʻole kūpono i ke kūlana o ke ʻano nui o ka rebar.
9. ʻO keʻano o ke kila kila kiʻekiʻe keʻano likeʻole, ke kiʻekiʻe o ka tonage o ka mīkiniʻoki anuanu, a maʻemaʻe a maʻemaʻe ka maka hope o ke poʻo oki.Ma muli o ka mea ʻilihune o nā mea hoʻopunipuni a me nā mea haʻahaʻa, ʻo ka maka hope o ke poʻo ʻokiʻoki pinepine i ke ʻano o ka hāʻule ʻana o ka ʻiʻo, ʻo ia hoʻi, ka luster unven a me non-metallic.A ma muli o ka ʻoki liʻiliʻi ʻana o ke poʻo o ka mea hana, hiki ke ʻike ʻia ke poʻo a me ka huelo.
10. Fake rectangular tube mea he nui na haumia, ka manoanoa o ke kila he uuku, a me ka nui i waho o ka tolerance i ka hihia o ka vernier caliper, hiki ke kaupaona a nānā.No ka laʻana, no ka rebar 20, ua ʻōlelo ka maʻamau ʻāina ʻo ka nui o ka hoʻomanawanui maikaʻi ʻole he 5%.Ke ana ʻana i 9M, ʻo 120kg kona kaumaha kumu o ke kumu hoʻokahi, a ʻo kona kaumaha haʻahaʻa: 120x (L-5%) = 114kg.ʻOi aku ka liʻiliʻi o ke kaumaha maoli o kahi aʻa hoʻokahi ma mua o 114kg, no laila he kila hoʻopunipuni %.Ma keʻano laulā, ʻoi aku ka maikaʻi o nā nui integer, ma muli o nā hewa kumulative a me ke kumumanaʻo probability.
11. Ke anawaena o loko o shoddy rectangular paipu fluctuates nui, no keia mau kumu: Steel wela instability i Yin - Yang ili.ʻAʻole kūlike ke ʻano o ke kila.Ma muli o ka maʻalahi o nā mea hana, haʻahaʻa ka ikaika o ke kumu, nui ka bounce o ka wili.E hoʻololi nui ʻia i loko o ka pule hoʻokahi, i ʻole like ka hoʻoikaika ʻana a maʻalahi hoʻi e haki.
12. ʻO ka hōʻailona kūʻai a me ka paʻi ʻana i nā paipu maikaʻi he mea maʻamau.
13. Aia ka mamao o na paipu huinahalike me na anawaena maluna o 16 maluna o IM.
ʻO nā kīʻaha longitudinal o ka ʻili kila shoddy he wavy pinepine.
ʻO ka pahu hao ʻaʻohe ʻāpana ʻāpana he ʻano helu e helu ai
