Hōʻike huahana

ʻO ka paipu kila kalapona a i ʻole ka paipu kila kalapona i hana ʻia me ka ingot kila a i ʻole ka paipu paʻa paʻa ma o ka perforation, a laila hana ʻia e ka ʻōwili wela, ka ʻōwili anu a i ʻole ke kiʻi anu. He kuleana koʻikoʻi ka paipu kila kalapona i ka ʻoihana paipu kila o Kina. ʻO ka mea maka o ka paipu kalapona he poepoe pahu hakahaka. Hoʻokiʻoki ʻia ka pahu pōʻai pōʻai a hana ʻia e ka mīkini ʻoki, a hoʻouna ʻia ka blank me ka ulu ʻana o kahi 1m i ka umu no ka hoʻomehana ʻana ma o ke kāʻei conveyor. Hoʻouna ʻia ka billet i ka umu no ka hoʻomehana ʻana ma kahi mahana o 1200 degere Celsius. He hydrogen a acetylene ka wahie. ʻO ka hoʻomalu wela i ka umu ahi ka pilikia nui. Ma hope o ka hoʻokuʻu ʻia ʻana o ka puʻupuʻu puʻupuʻu pōʻai mai ka umu, pono e hou ʻia ʻo ia ma ke kaomi ʻana. ʻO ka mea maʻamau, ʻo ka piercer maʻamau ʻo ia ka piercer roll conical. He kiʻekiʻe ka hana ʻana o kēia piercer, maikaʻi ka huahana maikaʻi, hoʻonui perforation nui a hiki ke komo i nā ʻano kila like ʻole. Ma hope o ka perforation, ʻolokaʻi ʻia ka pahu pōʻai blank e ʻekolu ʻōwili keʻa o ka ʻōwili, ʻōwili mau a extrusion paha. Ma hope o ka extrusion, wehe i ka paipu no ka nui. Huli ka mīkini nui i loko o ka embryo kila me ka wikiwiki nui ma o ka drill conical e hana i kahi paipu kila. Hoʻoholo ʻia ke anawaena o loko o ka paipu kila e ka lōʻihi o ke anawaena o waho o ka ʻāpana mīkini. Ma hope o ka nui ʻana, komo ka paipu kila i ka hale kiaʻi hoʻoluʻu a hoʻomaʻalili ʻia e ka wai. Ma hope o ka hoʻomahaʻana, e hoʻopololeiʻia ka paipu kila. Ma hope o ka hoʻopololei ʻana, hoʻouna ʻia ka paipu kila i ka mea ʻike kīnā metala (a i ʻole hydrostatic test) e ke kāʻei conveyor no ka ʻike hala o loko. Inā loaʻa nā māwae, nā ʻōpū a me nā pilikia ʻē aʻe i loko o ka paipu kila, e ʻike ʻia lākou. Pono e koho pono ʻia nā paipu kila ma ka lima ma hope o ka nānā ʻana i ka maikaʻi. Ma hope o ka nānā ʻia ʻana o ka paipu kila, ʻo ka helu, ka kikoʻī, ka helu hui hana, a me nā mea ʻē aʻe e kāpī ʻia me ka pena. A hoʻokuʻu ʻia i loko o ka hale kūʻai e ka crane.

27SiMn Steel Pipe = 27 silicon manganese paipu kila, ʻo ia kekahi o nā mea o ka paipu kila ʻole, a ʻo ka ʻike kalapona ma waena o 0.24-0.32%. Hoʻokaʻawale ʻia ka SIMN no ka mea ʻo ka maʻiʻo o ka manganese silika i loko o nā mea ʻelima (carbon C, silicon Si, manganese Mn, phosphorus P, sulfur s) ma kahi o 1.10-1.40%.

Maʻiʻo: ua hana ia ma ke kahua o ka paipu kila ma Kina no nā makahiki he 20. ʻOi aku ka nui o ka hui ma mua o 10 seamless steel pipe production laina, hana nui 27SiMn quenched and tempered steel pipe, API series pipeline steel pipe, carbon steel round pipe and American standard series steel pipe. Loaʻa iā ia ka laulā o nā noi. I kēia manawa ua hoʻopaʻa ʻia kāna mau mea kūʻai nui ma ʻApelika Hema, Central Asia, ʻEulopa a me nā ʻāina ʻē aʻe, me nā kaukani o nā mea kūʻai aku e hoʻolako i ka koi o ka mea kūʻai aku.
