I nā papahana halihali ʻaila a me ke kinoea hou a me ka mālama wai, ʻo ka ikaika a me ka hilinaʻi o nā paipu kila pipeline ka mea nui loa. Welina mai i ke ao o nā paipu kila kalapona i hoʻopili ʻia me ka wili - ke hoʻololi nei kēia ʻenehana hou i ke ʻano kuʻuna o ka hoʻopili ʻana i nā paipu metala. Ma ka ʻōwili ʻana i ke kila kila kalapona haʻahaʻa i loko o nā ʻāpana paipu ma nā kihi wili kikoʻī a laila hana i ka hoʻopili pololei ʻana, hana mākou i kahi moʻo o nā huahana kiʻekiʻe e ikaika, paʻa, a maʻalahi hoʻi.
Ma waena o nā ʻano paipu kila pipeline like ʻole,Paipu Laina SSAW X60a mePaipu Laina SSAW X70ʻelua mau huahana hana kiʻekiʻe i makemake nui ʻia ma ka mākeke.
Loaʻa i ka Paipu Laina X60 SSAW kahi ikaika haʻahaʻa loa (415 MPa) a kūpono ia no nā paipu hoʻoili ʻaila a me ke kinoea me ke kaomi waena a me ke kiʻekiʻe. Hiki iā ia ke kū i ke kaomi kūloko nui a me nā ukana o waho me ka mālama ʻana i ka paʻakikī maikaʻi a me ka hiki ke hoʻopili ʻia, e lilo ia i koho kūpono no nā ʻōnaehana paipu mamao loa ma uka a me waho.
ʻOi aku ka lōʻihi o ka paipu laina X70 SSAW, me ka ikaika haʻahaʻa loa o 485 MPa, e kūpono ai no nā papahana halihali ma lalo o nā kaomi kiʻekiʻe a me nā wahi koi. ʻO kona ikaika kiʻekiʻe e ʻae ai i ka hoʻohana ʻana i nā mānoanoa o ka paia lahilahi, no laila e hōʻemi ana i ke kaumaha o ka paipu, e hoʻohaʻahaʻa ana i nā kumukūʻai halihali a me ke kau ʻana, me ka mālama ʻana i ke kūpaʻa maikaʻi loa i ka deformation a me ka haki ʻana.
Hana ʻia kēia mau huahana ʻelua me ka hoʻohana ʻana i ke kaʻina hana kuʻi wili. Paʻa ke ʻano o ka kuʻi ʻana, kiʻekiʻe ka pono o ka hana ʻana, a hiki iā lākou ke hana maʻalahi i nā paipu kila nui a me nā paia mānoanoa, e hoʻokō ana i nā koi kūikawā o nā papahana like ʻole.
Ma ke ʻano he mea hoʻolako huahana, ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. kahi mea hana alakaʻi o nā paipu kila wili a me nā huahana uhi paipu kila ma Kina. Ua hoʻokumu ʻia ka ʻoihana i ka makahiki 1993 a aia ma ke kūlanakauhale ʻo Cangzhou, ka moku ʻo Hebei. Uhi ia i kahi ʻāpana o 350,000 mika kuea, he waiwai holoʻokoʻa o 680 miliona yuan, a i kēia manawa he 680 mau limahana. Hana ka ʻoihana i 400,000 tons o nā paipu kila wili i kēlā me kēia makahiki a he waiwai hoʻopuka makahiki o 1.8 biliona yuan.
Inā ʻoe e koho i ka X60 SSAW Line Pipe no nā papahana halihali maʻamau, a i ʻole e koho i ka X70 SSAW Line Pipe e hoʻoponopono i nā pilikia kaomi kiʻekiʻe, hiki iā Cangzhou Spiral Steel Pipe Group ke hāʻawi iā ʻoe i nā huahana hilinaʻi a me ke kākoʻo loea ʻoihana. Ua kūpaʻa mākou i ka hoʻohana ʻana i nā paipu kila kiʻekiʻe e hoʻopili i ka wā e hiki mai ana o ka ikehu o ka honua.
Inā makemake ʻoe e ʻike hou aku e pili ana i ka huahana a i ʻole e kiʻi i nā ʻano loea, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa.
