ʻO nā pono o ka A252 Grade 2 Steel Pipe Spiral Submerged Arc Welded Polypropylene Lined Pipe
Paipu laina polypropylenehāʻawi i nā pono he nui ke hoʻohana pū ʻia me ka hoʻoheheʻe ʻia ʻana o ka paipu kila A252 Grade 2.ʻO kekahi o nā pōmaikaʻi nui ʻo ka pale ʻana i ka corrosion e hele mai me ka polypropylene.Ma ka hoʻopili ʻana i ka paipu kila me ka polypropylene, pale ʻia ka ʻili o loko mai nā mea corrosive, e hōʻoia ana i ka lōʻihi a me ka hilinaʻi o ka ʻōnaehana paipu.He mea koʻikoʻi kēia i nā noi kahi e ʻike ʻia ai nā paipu i nā kemika koʻikoʻi a i ʻole nā kūlana kaiapuni.
Hoʻohui ʻia, ʻike ʻia nā paipu laina polypropylene no ko lākou mau ʻili o loko, e kōkua i ka hōʻemi ʻana i ka friction a hoʻomaikaʻi i ka kahe wai i loko o nā paipu.Hoʻonui kēia i ka pono a hoʻemi i ka hoʻohana ʻana i ka ikehu, e lilo ia i koho maikaʻi no nā ʻano hana ʻoihana a me nā ʻoihana.

ʻO kekahi pōmaikaʻi nui o ka hoʻohana ʻana i ka paipu laina polypropylene i loko o ka wiliwili arc submerged arc ʻo ia ka pale hou ʻana i ka ʻaʻahu.Hoʻohana ka polypropylene lining i mea pale, pale i nā paipu kila mai ka pōʻino abrasive a hoʻemi i ka pono no ka mālama pinepine a me ka hoʻoponopono.
Ma waho aʻe o nā pōmaikaʻi i hāʻawi ʻia e ka polypropylene lining, ʻo ka spiral submerged arc welding process kekahi mea nui i ka hana ʻana i kahi ʻōnaehana paipu kūpaʻa a hilinaʻi hoʻiA252 Papa 2 paipu kila.Ke hoʻohana nei kēia ʻenehana hoʻoheheʻe i kahi kaʻina hoʻoheheʻe flux-cored arc e hana i nā weld ikaika a maʻalahi e kūpono i nā kūlana kiʻekiʻe e pono ai no nā paipu ʻoihana.
Hoʻonui ʻia ka ikaika a me ka pololei o ka ʻōnaehana paipu ma ka hoʻohana ʻana i nā paipu wili pālua i hana ʻia e ka spiral submerged arc welding.Hoʻolālā ʻia kēia mau paipu e kū i nā koʻikoʻi kiʻekiʻe a hāʻawi i ka hana lōʻihi, e hoʻolilo iā lākou i koho mua no nā ʻano noi like ʻole.
I ka hōʻuluʻulu manaʻo, ʻo ka hui pū ʻana o ka paipu polypropylene lined a me ka spiral submerged arc welding o A252 Grade 2 paipu kila e hāʻawi i nā pono he nui no nā ʻōnaehana paipu ʻoihana.Mai ka pale ʻana i ka corrosion a me ka hoʻohaʻahaʻa ʻana i ka friction a hiki i ka pale ʻana i ka ʻaʻahu a me ka waimaka, hana pū kēia mau ʻāpana e hana i nā hoʻonā paipa kūpono a hilinaʻi.Ke hoʻomau nei nā ʻoihana e ʻimi i nā mea hana kiʻekiʻe a me nā ʻenehana hana, ʻo ka hoʻohana ʻana i ka paipa polypropylene lined a me ka spiral submerged arc welding e noho mau i ka koho mua no nā noi he nui.
