Ka pomaikai o kuhiliʻole kila welded paipu hana: Mua o na mea a pau, i ka hana ana o kuhiliʻole kila welded paipu, ke kino paipu e like squeezed, a laila ma hope online malamalama paa hoohehee annealing, ka ili lilo loa laumania, a me ka laumania ili. ʻAʻole maʻalahi ka paona, me nā hiʻohiʻona anti-scaling.He mea maikaʻi kēia i ka hoʻopau wela a ʻaʻole koi i ka hoʻomaʻemaʻe pinepine, mālama i ka manawa, hoʻoikaika a me ke kālā.ʻO ka lua, ʻo ka paipu welded kahi huahana hohonu o ka pā, a ʻaʻole like ka maikaʻi o ka mānoanoa o ka paia.I ka manawa like, hiki ke hoʻokaʻawale ʻia ka nui, me ka pololei kiʻekiʻe.ʻO ke kolu, ʻo ka mea kila kila i nā ʻano o ka pale ʻana i ka corrosion a me ke ola lawelawe lōʻihi.

ʻO ke kūlana o kēia manawa o nā huahana paipu i hoʻopaʻa ʻia: ʻAʻole i kūlike ka mana hana o ka paipu wili kila kila o Kina i ka makemake o ka mākeke kūloko.ʻAʻole i hoʻopau ka hapa nui o nā mea hana kaʻina hana o ka ʻenehana kuhili ʻole, e like me ka nele o ka mālama ʻana i ka wela a me nā lako hoʻāʻo pūnaewele, i hiki ai i ka hana o ka hui ke hāʻawi i ka pāʻani piha, hiki ke hana wale i nā paipu hoʻonaninani maʻamau, a me ka mākeke o 'Oi aku ka nui o na paipu wiliwili me ke kila kila haahaa i ka lako;ʻO nā paipu welded ʻoihana kiʻekiʻe, e like me nā paipu mīkini kemika a me nā paipu hoʻololi wela, he mau mea hana liʻiliʻi hiki ke hana ʻia, akā ʻaʻole lawa ka mana hana.ʻenehana Hangao (Mekini SEKO) SZG-JM moʻo pololei kuhiliʻole kila welded paipu laina hana hoʻonā i kēia pilikia.ʻO ka laina hana holoʻokoʻa e pili ana i nā kaʻina hana e like me ka hoʻokumu ʻana i ka welding, ka hoʻoheheʻe ʻana o ka wili i loko, ka wili wili ʻana, ka annealing mālamalama, a me ka ʻoki ʻana.Hoʻonohonoho ka ʻōnaehana uila naʻauao i ka hana o kēlā me kēia ʻāpana, e hoʻomaikaʻi i ka pono ʻoiai e hōʻemi ana i ka ikehu.
Hiki i ka paipu welded ke hana i nā mea hoʻololi wela?
1. Hiki i nā paipu huahana maʻamau kiʻekiʻe
ʻO ka pahu hoʻololi wela he ʻāpana koʻikoʻi o nā mea hoʻololi wela o ka tube-a-tube, a ua koho ʻia ka mea hoʻololi wela e like me ke kaomi a me ke ʻano wai.I kēia manawa, ʻo kekahi o nā kuhi hewa ʻole i ke koho ʻana i nā paipu hoʻoheheʻe wela ma ka mākeke ʻaʻole hiki ke hoʻohana ʻia nā paipu hoʻoheheʻe ʻana i ka wela, akā ʻo GB / 151-1999 e hōʻike maopopo ana e hiki ke koho ʻia nā ʻaoʻao o ka paipu. ʻo ≤6.4MPa.ʻOi loa i kēia manawa ʻo ke kaʻina hana o nā paipu i hoʻopaʻa ʻia i ke kila kila, hiki ke hoʻokō pono i nā pono o nā paipu hoʻololi wela maʻamau, a hōʻike i kāna mau pono kūʻokoʻa.
2. Ua oo ka hana hana, austenitic kuhiliʻole welded paipu e lilo i ka mua koho
No ka mea, ʻo ka mea hoʻololi wela ka ʻili o ka mea hoʻololi wela, ʻo ka nui o ka mea hoʻololi wela ka mana nui i ka hoʻoili wela.I ka hoʻohana ʻana i nā paipu anawaena liʻiliʻi, ʻoi aku ka nui o ka wahi hoʻololi wela i kēlā me kēia leo o ka mea hoʻololi wela, ʻoi aku ka paʻakikī o nā mea hana, ʻoi aku ka liʻiliʻi o ka hoʻohana metala no kēlā me kēia wahi hoʻoili wela, a ʻoi aku ka kiʻekiʻe o ka hoʻoili wela.ʻOiai paʻakikī ka hana ʻana, ʻo ka hoʻohana ʻana i nā paipu welded austenitic stainless steel e like me nā paipu hoʻololi wela ke pale aku i nā pilikia ma luna.No ka mea austenitic kuhiliʻole kila welded paipu i maikai corrosion kū'ē a me ka laumania surfaces, a me ka hana kaʻina hana oʻo, no laila austenitic Kuhiliʻole kila welded paipu ke koho mua no ka wela exchanger paipu.ʻO nā mea i hiki ke hana ʻia e ka ʻenehana Hangao (Mekini SEKO) SZG-JM series welded pipe production line: stainless steel, austenite, ferrite, titanium alloy a me ke kila pālua ʻelua, he mea maʻalahi loa a hiki ke hoʻonohonoho a hoʻoponopono ʻia e like me nā kauoha a ka mea kūʻai aku.
