Ke Kumukuai Haahaa Loa DIN 1629 St52 Pipe kila maʻemaʻe me ke kūlana kiʻekiʻe
ʻO ka wehewehe pōkole:
ʻO kēia Alloy Steel Pipe me 12cr1MOV Material he paipu kila maʻemaʻe hiki ke hoʻohana ʻia i ka petroleum, kemika, ka mana uila a me nā noi boiler.Loaʻa iā ia nā hiʻohiʻona o ke kūpaʻa anu, ke kūpaʻa wela a me ke kūpaʻa corrosion.12Cr1MoV kahi ʻano paipu huila.ʻO ke kumu nui ka hana ʻana i nā ʻāpana hana kila i loko o ka paila.
Me kā mākou ʻenehana alakaʻi a me ko mākou ʻuhane o ka hana hou, ka hui like ʻana, nā pōmaikaʻi a me ka ulu ʻana, e kūkulu mākou i kahi wā e hiki mai ana me kāu ʻoihana hanohano no ka Super Lowest Price DIN 1629 St52 Seamless Steel Pipe me ka High Quality, Mahalo no ka lawe ʻana i kou manawa waiwai. e kipa mai iā mākou a e nānā i mua e loaʻa kahi hui maikaʻi me ʻoe.
Me kā mākou ʻenehana alakaʻi a me ko mākou ʻuhane o ka hana hou, ka hui like ʻana, nā pōmaikaʻi a me ka ulu ʻana, e kūkulu mākou i kahi wā e hiki mai ana me kāu ʻoihana hanohanoKina DIN 1629 St52 Paipu kila, Hana ikaika e hoʻomau i ka holomua, hana hou i ka ʻoihana, hana i nā hana āpau i ka ʻoihana papa mua.Ke ho'āʻo nei mākou i kā mākou mea maikaʻi loa e kūkulu i ke kumu hoʻokele ʻepekema, e aʻo i ka ʻike loea nui, e hoʻomohala i nā lako hana kiʻekiʻe a me ke kaʻina hana, e hana i nā mea kūʻai maikaʻi kāhea mua, ke kumu kūʻai kūpono, ke kūlana kiʻekiʻe o ka lawelawe, ka lawe wikiwiki ʻana, e hōʻike iā ʻoe e hana. waiwai hou .
ʻO ka mahana lawelawe he 580 ℃, a pono ka pā kila e loaʻa ka ikaika hoʻomanawanui kiʻekiʻe.Hāʻawiʻia ka pā kila ma ke kūlana maʻamau a me ka huhū.Hoʻokumu ʻia ka paipu huila 12Cr1MoVG ma luna o ke kila carbon structural kiʻekiʻe, a ua hoʻohui ʻia hoʻokahi a i ʻole kekahi mau mea ala e hoʻomaikaʻi ai i ka waiwai mechanical, ka paʻakikī a me ka paʻakikī o ke kila.ʻO nā huahana i hana ʻia me ia ʻano kila e koi pinepine i ka mālama wela (hoʻomaʻamaʻa a hoʻopau paha a hoʻoulu ʻia);ʻO nā ʻāpana a me nā ʻāpana i hana ʻia i ia mau mea pono e hoʻopau i ka quenching a me ka hoʻomaʻamaʻa ʻana a i ʻole ka mālama ʻana i ke kemika (carburizing, nitriding, etc.), surface quenching or high-frequency quenching ma mua o ka hoʻohana ʻana.No laila, e like me nā ʻano mea like ʻole (ʻoi aku ka nui o ke kalapona), nā kaʻina hana wela a me nā noi, hiki ke hoʻokaʻawale ʻia kēlā mau kila i carburized, Quenched and tempered and nitrided steels.
ʻO ka mea mua, hiki iā ia ke 100% recycled, mālama i ka ikehu a me ka palekana o ke kaiapuni.
ʻO ka lua, he plasticity kiʻekiʻe loa ia a hiki ke hoʻohana ʻia no ka hana lua a me ka hana ʻana.
ʻO ke kolu, loaʻa iā ia ka conductivity thermal maikaʻi a me ka hiki ke kolo wela kiʻekiʻe.
ʻO ka hā, he maikaʻi ke kūpaʻa oxidation a me ke kūpaʻa corrosion.
ʻO ka lima, he hana maikaʻi ke anuanu a me ka wela.
ʻO 12Cr1MoVG kahi ʻano o ka paipu kila chromium molybdenum, kahi o nā mea kemika nui he kalapona 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, phosphorus ʻaʻole ʻoi aku ma mua o 0.035, sulfur ʻaʻole i ʻoi aku ma mua o 0.035, 0.035, sulfur. molybdenum 0.25-0.35, alum 0.15-0.30, etc.
ʻO ka mea mua, hoʻohana nui ʻia ia e hana i nā paipu hoʻoheheʻe kiʻekiʻe no ka hoʻomehana ʻana i nā wahi o nā paila wai me ke kaomi kiʻekiʻe a ma luna.
ʻO ka lua, hoʻohana nui ʻia ia i nā superheaters, nā poʻomanaʻo a me nā ʻauwaʻa mahu nui o ka home high-pressure, ultra-high pressure a me subcritical power station boilers.
ʻO ke kolu, hoʻohana nui ʻia nā paipu anawaena nui ma ke ʻano he poʻo a me ka Main Steam Conduits me nā ʻāpana mahu ma lalo o 565 ℃.
ʻO ka mua, ke kahe kaʻina o ka ʻōwili wela (extrusion seamless steel pipe):
ʻO ka paipu puʻupuʻu → ka hoʻomehana → ke kī ʻana → ʻekolu ʻōwili keʻa o ka ʻōwili, ka ʻōwili mau ʻana a i ʻole ka extrusion → ka wehe ʻana i ka paipu → ka nui (a i ʻole ka hoʻohaʻahaʻa ʻana) → ka hoʻoluʻu → billet → hoʻopololei → ka hoʻāʻo hydrostatic (a i ʻole ka ʻike kīnā) → ka māka → hale waihona.
ʻO ka lua, ke kaha kiʻi anuanu (rolling) kaʻina hana paipu kila ʻole:
ʻO ka pila puʻupuʻu pōʻai → ka hoʻomehana → ke ʻoki ʻana → ke poʻo → annealing → pickling → ka uhi ʻaila (ka uhi keleawe) → ke kaha kiʻi anuanu (cold rolling) → billet tube → ka mālama wela → straightening → hydrostatic test (a i ʻole ka ʻike kīnā) → marking → warehousing.
