ʻO Royal Group, i hoʻokumu ʻia i ka makahiki 2012, he ʻoihana ʻenehana kiʻekiʻe e kālele ana i ka hoʻomohala ʻana, ka hana ʻana a me ke kūʻai aku ʻana i nā huahana kuhikuhipuʻuone. Aia ko mākou keʻena nui ma Tianjin, ke kūlanakauhale waena o ka ʻāina a me kahi hānau o "Three Meetings Haikou". Loaʻa iā mākou nā lālā ma nā kūlanakauhale nui ma ka ʻāina.
ʻO ka paipu kila kalapona kahi mea paipu maʻamau i hana ʻia me ke kalapona a me ka hao, i hoʻohana nui ʻia i ka ʻoihana. Ma muli o kona kūpaʻa maikaʻi loa, ka ikaika, a me ke kūpaʻa ʻana i ka pala, hoʻohana pinepine ʻia ia i nā ʻoihana ʻaila, kemika, a me ke kūkulu ʻana.
Ma muli o ke kaʻina hana, ua hoʻokaʻawale nui ʻia ka paipu kila kalapona ma ke ʻano he paipu welded a me ka paipu seamless. Hana ʻia ka paipu welded ma ka welding ʻana i nā papa kila a i ʻole nā ʻāpana i hui pū ʻia, e hāʻawi ana i ka pono hana kiʻekiʻe a me ke kumukūʻai haʻahaʻa. Hoʻohana pinepine ʻia no ka halihali wai haʻahaʻa haʻahaʻa, e like me ka hoʻolako wai hale a me nā paipu hoʻokahe wai. Hana ʻia ka paipu seamless mai nā billets paʻa ma o nā kaʻina hana e like me ke kī ʻana, ka ʻōwili wela, a me ka ʻōwili anu. ʻAʻohe o kona paia i nā welds, e hopena ana i ka ikaika a me ka sila ʻana, e ʻae ana iā ia e kū i nā kaomi kiʻekiʻe a me nā wahi ʻino. ʻO nā pipelines kaomi kiʻekiʻe i ka ʻoihana petrochemical, no ka laʻana, hoʻohana pinepine ʻia no ka paipu seamless.
Ma ke ʻano, hele mai nā paipu kila kalapona i nā ʻano poepoe a me nā ʻano huinahā. Hoʻopaʻa like ʻia nā paipu poepoe, e hāʻawi ana i ka pale liʻiliʻi i ka lawe ʻana o ka wai. Hoʻohana nui ʻia nā paipu huinahā a me nā ʻano huinahā i nā hale kūkulu a me ka hana ʻana i nā mīkini, e hāʻawi ana i nā hale kākoʻo paʻa. He kuleana koʻikoʻi ko nā ʻano paipu kila kalapona like ʻole i nā papahana ʻenekinia like ʻole.
ʻO kā mākou paipu kila kalapona
Hāʻawi mākou i kahi laulā piha o nā huahana kila kalapona, mai nā paipu a i nā papa, nā ʻōwili a i nā profiles, e hoʻokō i nā pono o kāu mau papahana like ʻole.
Hana ʻia nā paipu kila galvanized mai kahi paipu kila metala me kahi uhi zinc i hana ʻia ma luna o ka ʻili ma o ka galvanizing wela a i ʻole ka electroplating. Hoʻohui i ka ikaika kiʻekiʻe o ke kila me ke kūpaʻa maikaʻi loa o ka uhi zinc, hoʻohana nui ʻia lākou i ke kūkulu ʻana, ka ikehu, ka halihali, a me ka hana mīkini. Aia ko lākou pono nui ma ka ʻoiaʻiʻo e hoʻokaʻawale ka uhi zinc i ka mea kumu mai nā mea corrosive ma o ka pale electrochemical, e hoʻolōʻihi nui ana i ke ola lawelawe o ka paipu me ka mālama ʻana i nā waiwai mechanical o ke kila e hoʻokō i nā koi ukana kūkulu o nā kūlana like ʻole.
Paipu kila poepoe Galvanized
Nā ʻano ʻāpana keʻaʻO ka ʻāpana kea poepoe e hāʻawi i ke kūpaʻa haʻahaʻa i ke kahe a me ke kūpaʻa like i ke kaomi, e kūpono ai no ka halihali wai a me ke kākoʻo kūkulu.
Nā Mea Hana Maʻamau:
Mea KumuKe kila kalapona (e like me Q235 a me Q235B, ikaika kūpono a me ke kumukūʻai kūpono), ke kila haʻahaʻa-alloy (e like me Q345B, ikaika kiʻekiʻe, kūpono no nā hana kaumaha); loaʻa nā mea kumu kila kila (e like me ke kila kila galvanized 304, e hāʻawi ana i ke kūpaʻa waikawa a me ka alkali a me ka nani) no nā hana kūikawā.
Nā Mea Papa GalvanizedʻO ka zinc maʻemaʻe (ka galvanizing wela me ka nui o ka zinc o ≥98%, ka mānoanoa o ka papa zinc o 55-85μm, a me ka wā pale ʻana i ka pala o 15-30 mau makahiki), ka hui zinc (zinc electroplated me kahi liʻiliʻi o ka alumini/nickel, ka mānoanoa o 5-15μm, kūpono no ka pale ʻana i ka pala o loko).
Nā Nui Maʻamau:
Anawaena o waho: DN15 (1/2 ʻīniha, 18mm) a i DN1200 (48 ʻīniha, 1220mm), Mānoanoa o ka Paia: 0.8mm (paipu hoʻonaninani paia lahilahi) a i 12mm (paipu kūkulu paia mānoanoa).
Nā Kūlana Pili: GB/T 3091 (no ka halihali wai a me ke kinoea), GB/T 13793 (paipu kila uila i hoʻopili pololei ʻia), ASTM A53 (no nā paipu kaomi).
Paipu kila kila i hoʻopaʻa ʻia
Nā ʻano ʻāpana keʻaʻO ka ʻāpana kea huinahā (ka lōʻihi o ka ʻaoʻao a×a), ka paʻakikī torsional ikaika, a me ka pili planar maʻalahi, hoʻohana pinepine ʻia i nā ʻano mōlina.
Nā Mea Hana Maʻamau:
ʻO ke kumu nui ʻo Q235B (kū i nā koi amo o ka hapa nui o nā hale), me Q345B a me Q355B (ka ikaika hua kiʻekiʻe, kūpono no nā hale kū i ke ōlaʻi) i loaʻa no nā noi kiʻekiʻe.
ʻO ke kaʻina hana galvanizing ka galvanizing wela-dip (no ka hoʻohana ʻana i waho), ʻoiai ʻo ka electrogalvanizing e hoʻohana pinepine ʻia no nā pale hoʻonaninani i loko.
Nā Nui Maʻamau:
Ka Lōʻihi o ka ʻAoʻao: 20 × 20mm (nā papa liʻiliʻi) a i 600 × 600mm (nā hale kila kaumaha), ka mānoanoa o ka paia: 1.5mm (ka paipu lako paia lahilahi) a i 20mm (ka paipu kākoʻo alahaka).
Ka lōʻihi6 mika, loaʻa nā lōʻihi maʻamau o 4-12 mika. Pono nā papahana kūikawā e hoʻopaʻa mua.
ʻO ka Tube Huinahā kila Galvanized
Nā ʻano ʻāpana keʻaʻO ka ʻāpana keʻa huinahā (ka lōʻihi o ka ʻaoʻao a × b, a ≠ b), me ka ʻaoʻao lōʻihi e hoʻokūpaʻa ana i ke kū'ē kūlou a me ka ʻaoʻao pōkole e mālama ana i ka mea. Kūpono no nā hoʻonohonoho maʻalahi.
Nā Mea Hana Maʻamau:
Ua like ke ʻano o ke kumu me ka paipu huinaha, me Q235B e helu ana ma luna o 70%. Hoʻohana ʻia nā mea haʻahaʻa-metala no nā hiʻohiʻona ukana kūikawā.
Hoʻoponopono ʻia ka mānoanoa o ke galvanizing e like me ke kaiapuni hana. No ka laʻana, ʻo ka galvanizing hot-dip ma nā wahi kahakai e pono ai he ≥85μm.
Nā Nui Maʻamau:
Lōʻihi o ka ʻaoʻao: 20 × 40mm (pale lako liʻiliʻi) a i 400 × 800mm (nā purlins hale hana ʻoihana). Mānoanoa o ka paia: 2mm (kaumaha māmā) a i 25mm (paia mānoanoa loa, e like me nā mīkini awa).
Ka Hoʻomanawanui Ana:Hewa o ka Lōʻihi o ka ʻAoʻao: ±0.5mm (paipu pololei kiʻekiʻe) a i ±1.5mm (paipu maʻamau). Hewa o ka Mānoanoa o ka Paia: I loko o ±5%.
Hāʻawi mākou i kahi laulā piha o nā huahana kila kalapona, mai nā paipu a i nā papa, nā ʻōwili a i nā profiles, e hoʻokō i nā pono o kāu mau papahana like ʻole.
ʻO ka paipu kila kila he paipu metala e hoʻohui i ke kūpaʻa ʻana i ka pala, ka ikaika kiʻekiʻe, ka hoʻomaʻemaʻe a me ka palekana o ke kaiapuni. Uhi ia i nā ʻano like ʻole e like me nā paipu humuhumu ʻole a me nā paipu i hoʻopaʻa ʻia. Hoʻohana nui ʻia ia i ka ʻenekinia kūkulu hale, kemika a me nā lāʻau lapaʻau, ka halihali ikehu a me nā ʻoihana ʻē aʻe.
Mai kahi hiʻohiʻona hana, ua hoʻokaʻawale nui ʻia nā ʻōmole poepoe kila kila i loko onā paipu humuhumu ʻolea menā paipu i hoʻopili ʻia. Nā paipu humuhumu ʻolehana ʻia ma o nā kaʻina hana e like me ka perforation, ka ʻōwili wela, a me ke kahakiʻi anu, e hopena ana i nā humuhumu i hoʻopaʻa ʻole ʻia. Hāʻawi lākou i ka ikaika holoʻokoʻa a me ke kūpaʻa kaomi, e kūpono ai lākou no nā noi e like me ka lawe ʻana i ke kahe wai kiʻekiʻe a me ka lawe ʻana i ka ukana mechanical.Nā paipu i hoʻopili ʻiaHana ʻia mai nā pepa kila kila, ʻōwili ʻia i ke ʻano, a laila hoʻopaʻa ʻia. He kiʻekiʻe ko lākou pono hana a me ke kumukūʻai haʻahaʻa, e hoʻohana nui ʻia ai i ka halihali haʻahaʻa a me nā noi hoʻonaninani.
Ana ʻāpana kea: Loaʻa nā ʻāpana like ʻole o nā paipu huinahā i ka lōʻihi o ka ʻaoʻao mai nā paipu liʻiliʻi 10mm × 10mm a i nā paipu nui 300mm × 300mm. Loaʻa pinepine nā ʻāpana huinahā i nā nui e like me 20mm × 40mm, 30mm × 50mm, a me 50mm × 100mm. Hiki ke hoʻohana ʻia nā nui nui no ke kākoʻo ʻana i nā hale nui. Pae Mānoanoa o ka Paia: Hoʻohana nui ʻia nā paipu paia lahilahi (0.4mm-1.5mm ka mānoanoa) i nā hana hoʻonaninani, e hōʻike ana i ka māmā a me ka hana maʻalahi. ʻO nā paipu paia mānoanoa (2mm ka mānoanoa a ʻoi aku, me kekahi mau paipu ʻoihana e hiki ana i 10mm a ʻoi aku) he kūpono no nā hana halihali ukana ʻoihana a me nā hana halihali kaomi kiʻekiʻe, e hāʻawi ana i ka ikaika nui a me ka hiki ke halihali kaomi.
Ma ke ʻano o ke koho ʻana i nā mea, hana nui ʻia nā paipu poepoe kila kila mai nā papa kila kila maʻamau. No ka laʻana,304hoʻohana pinepine ʻia no nā paipu hana meaʻai, nā lima hana hale, a me nā lako hale.316Hoʻohana pinepine ʻia nā paipu poepoe kila kila i ke kūkulu ʻana ma ke kahakai, nā paipu kemika, a me nā lako moku.
ʻO nā paipu poepoe kila kila waiwai, e like me201a me430, hoʻohana nui ʻia i nā pale hoʻonaninani a me nā ʻāpana kūkulu māmā, kahi e haʻahaʻa ai nā koi kūpaʻa i ka popopo.
ʻO kā mākou paipu kila kila
