Mai kona hana ʻia ʻana ma mua o hoʻokahi haneli i hala aku nei, ua lilo ke kila kila i mea hoʻohana nui a kaulana i ka honua. Hāʻawi ka maʻiʻo Chromium i kona kūpaʻa kūʻē i ka corrosion. Hiki ke hōʻike ʻia ke kūʻē ʻana i ka hōʻemi ʻana i nā waikawa a me ka hoʻouka kaua ʻana i nā hoʻonā chloride. He liʻiliʻi ka pono o ka mālama ʻana a me ka ʻālohilohi maʻamau, e lilo ia i mea maikaʻi a maikaʻi loa no nā paipu kila kila. Hāʻawi ʻia ka paipu kila kila i nā ʻano huahana like ʻole, me nā paipu welded a me nā paipu seamless. Hiki ke hoʻololi i ka haku mele, hiki ke hoʻohana ʻia i nā ʻāpana like ʻole. Hoʻohana mau ʻia ka paipu kila kila e nā ʻoihana ʻoihana he nui. Ma kēia moʻomanaʻo moʻomanaʻo, e ʻōlelo ʻia nā ʻano paipu kila kila e pili ana i nā ʻano hana hana a me nā kūlana like ʻole. Ma waho aʻe o kēlā, aia kēia pou blog i nā wahi noi like ʻole o nā paipu kila kila ma nā ʻoihana like ʻole.

Nā ʻano like ʻole oPaipu Kinohi PilikinoMa muli o ka Hana Hana Hana

ʻO ke ʻano o ka hana ʻana i nā paipu welded mai ka coil mau a i ʻole ka pā e komo i ka ʻōwili ʻana i ka pā a i ʻole ka wili i loko o kahi ʻāpana pōʻai me ke kōkua o kahi ʻōwili a i ʻole nā ​​​​mea hana kulou. Hiki ke hoʻohanaʻia ka mea hoʻopihapiha i ka hana nui. He emi ke kumu kūʻai o nā paipu welded ma mua o nā paipu seamless, nona ke ʻano hana ʻoi aku ka nui o ke kumu kūʻai. ʻOiai ʻo kēia mau hana hana, ʻo ia hoʻi nā ʻano welding he ʻāpana koʻikoʻi o nā paipu kila kila, ʻaʻole e haʻi ʻia nā kikoʻī o kēia mau ʻano welding. He kumuhana paha ia o kekahi moʻomanaʻo moʻomanaʻo a mākou. Ma hope o ka ʻōlelo ʻana, ʻike pinepine ʻia nā ala wili no nā paipu kila kila ma ke ʻano he mau pōkole. He mea nui e kama'āina i kēia mau pōkole. Nui nā ʻenehana welded, e like me:

• EFW– ʻO ke kuʻi fusion uila
• ERW– Kuʻi uila kūʻē
• HFW– Kiekie alapine weld
• SAW– Ka hoʻoheheʻe ʻia ʻana o ke poʻo i lalo (spiral seam a i ʻole seam lōʻihi)

Aia kekahi mau ʻano paipu kila kila ma nā mākeke. Ma nā kikoʻī hou aʻe, ma hope o ka hana ʻana o ke kuʻekuʻe uila, ʻōwili ʻia ke metala i kona lōʻihi. Hiki ke hana ʻia ka paipu seamless o kēlā me kēia lōʻihi me ka extrusion metala. ʻO nā paipu ERW he mau hono i hoʻopaʻa ʻia ma ko lākou ʻāpana keʻa, akā ʻo nā paipu ʻole he mau hui e holo ana i ka lōʻihi o ka paipu. ʻAʻohe wili i loko o nā paipu liʻiliʻi ʻoiai ua hana ʻia ke kaʻina hana holoʻokoʻa ma o ka billet puni paʻa. I nā anawaena like ʻole, ua hoʻopau ʻia nā paipu seamless i ka mānoanoa o ka paia a me nā kikoʻī kikoʻī. No ka mea ʻaʻohe seam ma ke kino o ka paipu, hoʻohana ʻia kēia mau paipu i nā noi kiʻekiʻe e like me ka lawe ʻana i ka aila a me ke kinoea, nā ʻoihana, a me nā refineries.

Nā ʻano ʻano paipu kuhili ʻole – Ma muli o nā pae Alloy

He mana nui ko ka haku mele ʻana o ke kila holoʻokoʻa i nā waiwai mechanical a me nā wahi hoʻohana. No laila, ʻaʻole ia he mea kupanaha hiki ke hoʻokaʻawale ʻia lākou ma ke ʻano o kā lākou haku mele. Eia nō naʻe, ʻoiai e hoʻāʻo nei e ʻike i ka pae o kahi paipu kila kila kūikawā, hiki ke ʻike ʻia nā ʻano nomenclatures like ʻole. ʻO nā kūlana i hoʻohana nui ʻia i ka wā e koho ai i nā paipu kila ʻo DIN (German), EN, a me nā helu ASTM. Hiki i kekahi ke nīnau i ka papa kuhikuhi e ʻimi i nā māka like. Hāʻawi ka papa ma lalo i kahi hiʻohiʻona kūpono o kēia mau kūlana like ʻole.

Papa 1. He mahele o ka papa kuhikuhi no na mea paipu kila kuhilihini

Nā ʻano like ʻole e pili ana i nā kikoʻī ASTM

He ʻōlelo maʻamau ia e pili pono ana ka ʻoihana a me nā kūlana. ʻOkoʻa paha ka hopena o ka hana ʻana a me ka hoʻāʻo ʻana ma muli o nā ʻokoʻa o nā kūlana hoʻonohonoho like ʻole no nā ʻano laulā noiʻi. Pono ka mea kūʻai aku e hoʻomaopopo mua i nā kumu o nā kikoʻī ʻoihana like ʻole no kā lākou papahana, ma mua o ka hana ʻana i nā hana kūʻai. He ʻōlelo pololei nō hoʻi no nā paipu kila kila.

ʻO ka ASTM kahi pōkole no ka American Society for Testing and Materials. Hāʻawi ʻo ASTM International i nā kūlana lawelawe a me nā mea ʻenehana no kahi ākea o nā ʻoihana. Ua lawelawe kēia hui i nā kūlana 12000+ i hoʻohana ʻia i nā ʻoihana a puni ka honua. ʻO nā paipu kila kila a me nā mea pono e pili ana i nā kūlana 100. ʻAʻole like me nā kino maʻamau ʻē aʻe, ʻo ASTM kahi kokoke i nā ʻano paipu āpau. No ka laʻana, e like me nā mea paipu ʻAmelika, hāʻawi ʻia ka spectrum holoʻokoʻa o ka paipu. Hoʻohana ʻia nā paipu kalapona ʻole me nā kikoʻī kūpono no nā lawelawe wela kiʻekiʻe. Ua wehewehe ʻia nā kūlana ASTM e ka hoʻoholo ʻana o ka haku mele a me nā kaʻina hana e pili ana i ka mea. Hāʻawi ʻia kekahi mau mea maʻamau ASTM ma lalo nei ma ke ʻano he laʻana.

• A106- No nā lawelawe wela wela
• A335–Seamless ferritic steel pipe (No ka wela wela)
• A333- Nā paipu kila welded a me ka ʻole (No ka wela haʻahaʻa)
• A312- No ka lawelawe corrosive maʻamau a me ka lawelawe wela kiʻekiʻe, hoʻohana ʻia ka hana anu, wili pololei ʻia, a me nā paipu seamless.

Nā ʻano ʻokoʻa o nā paipu kila kila ma muli o nā wahi noi

Nā paipu hoʻomaʻemaʻe:Hana ʻia nā paipu maʻemaʻe i ke kila kila a hoʻohana ʻia i nā noi hoʻomaʻemaʻe kiʻekiʻe e like me nā noi maʻalahi. Hāʻawi ʻia kēia ʻano paipu i ka mea nui loa i ka ʻoihana no ke kahe wai kūpono. ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion a ʻaʻole ʻōpala ma muli o kona maʻalahi o ka mālama ʻana. Hoʻoholo ʻia nā palena hoʻomanawanui like ʻole ma muli o ka noi. Hoʻohana mau ʻia nā paipu sanitary me nā māka ASTMA270.

Paipu Mechanical:Hoʻohana pinepine ʻia nā ʻāpana Hallow, nā ʻāpana lawe, a me nā ʻāpana cylinder i nā noi paipu mechanical. Hiki ke hoʻoponopono maʻalahi i nā ʻano mechanics i kahi ākea o nā ʻano ʻāpana e like me ke ʻano ʻāpana ʻehā, square, a me nā ʻano ʻē aʻe e hoʻohui i nā ʻano kuʻuna a i ʻole nā ​​​​mea kuʻuna. ʻO A554 a me ASTMA 511 nā ʻano papa i hoʻohana pinepine ʻia i nā noi mechanical. Loaʻa iā lākou ka machinability maikaʻi loa a hoʻohana ʻia i nā noi e like me ka automotive a me nā mīkini mahiʻai.

ʻO nā paipu i poni ʻia:Hoʻohana ʻia nā paipu kila kila i poni ʻia i loko o ka hale e like me nā kikoʻī. ʻO nā paipu i poni ʻia e kōkua i ka hōʻemi ʻana i ka ʻaʻahu a me ka waimaka ma nā mea hana. He kōkua nō hoʻi i ka hōʻemi ʻana i ka hoʻopili ʻana a me ka hoʻohaumia ʻana o nā ʻano mea hana. He ākea ka hoʻohana ʻana o ka ʻili electropolished. ʻAʻole pono nā paipu i poni ʻia i ke kila kila. He kuleana koʻikoʻi a koʻikoʻi nā paipu poli i loko o nā noi aesthetic a me ka hoʻolālā.
