Paipu kila SSAW No ka Laina Wai Malalo
E hoʻokuʻu i ke kila kila i hoʻoheheʻe ʻiapaipu no nā laina wai lalo
Ua hoʻokumu ʻo Cangzhou Spiral Steel Pipe Group Co., Ltd. i kāna paipu kila hili i ka honua, he paipu kila wiliwili e hoʻololi i ka ʻoihana paipu wai honua. ʻO kēia paipu he mea hoʻololi pāʻani i ka wai kūloko a me ka mākeke hoʻopuka wai ma muli o kona ʻano kiʻekiʻe a me ka hana kiʻekiʻe.

Nā paipu kila SSAWua hana ʻia me nā wili kila e like me nā mea maka, i hoʻokuʻu ʻia i ka mahana mau, a wili ʻia e ke kaʻina hana kuʻi ʻana i nā ʻaoʻao pālua ʻelua. ʻO kēia ʻenehana hana hou e hōʻoia i nā pae kiʻekiʻe o ka pololei a me ka lōʻihi, e hana i kā mākou paipu kūpono no nā noi laina wai honua.
Ka puuwai o keiapaipu kila wiliwiliʻo ia kona hoʻolālā spiral kū hoʻokahi. Hāʻawi ʻia ke kila kila i loko o ka mea paipu welded a ʻōwili mālie ʻia e nā huila lehulehu e hana i kahi paipu pōʻai me ka wehe ʻana. Loaʻa iā ia ka hiki ke hoʻololi i ka nui o ka hōʻemi o ka extrusion roller, a hiki ke hoʻomalu ʻia ka weld gap ma waena o 1-3mm e hōʻoia i kahi pilina paʻa a paʻa. Eia kekahi, ʻo nā ʻaoʻao ʻelua o ka hui welded e ʻoluʻolu maikaʻi, e hāʻawi ana i kahi hoʻopau maikaʻi.
ʻO nā paipu kila SSAW he mau hiʻohiʻona e hoʻokaʻawale iā lākou mai nā paipu kila maʻamau. ʻO kona ʻano spiral he ikaika maikaʻi loa a kūʻē i nā ikaika o waho, e hōʻoiaʻiʻo ana i ka palekana a me ka hilinaʻi o ka ʻōnaehana lawe wai. Eia kekahi, ʻo ke kaʻina hana hoʻoheheʻe kiʻekiʻe e hōʻoiaʻiʻo i ka leak-proof o nā hui a pale i ka ʻike wai a i ʻole ka hoʻohaumia ʻana. Me kona kūkulu paʻa ʻana a me nā pilina paʻa, e hōʻoia kēia paipu i ka hana mau loa a hōʻemi i ka pono o ka mālama ʻana, e lilo ia i kumu kūʻai kūpono no kēlā me kēia papahana laina wai honua.
