ʻO ke alakaʻi alakaʻi i kahi papa kiʻekiʻe e helu ai i ka 1 kila kila kila kila
E aʻo e pili ana iā A252 mau pākeke pāa 2 mau kīpī:
A252 kumu 2 kīleʻahe paila kila carbon i hoʻolālā kūikawāʻia no ka hoʻohanaʻana i ka hoʻoikaikaʻana i nā noi piping a me nā noi. Hanaʻia ia e like me ka astm (ʻAmelikaʻAmelika no ka ho'āʻoʻana a me nā lako hana) nā kūlana kiʻekiʻe, e hōʻoia i ka pololei kiʻekiʻe. Hōʻike ka papa inoa 2 i ka papa hana i hanaʻia e hoʻohanaʻia ai ka paila submered arlding a iʻole nā hana maʻamau.
Ka mea nui o ka papalua i kauʻia i ka ulana.
Papalua pālua i ka weheʻana, ua kaulana hoʻiʻo DSAW, he kaʻina hana maikaʻi loa i hoʻohanaʻia e hui pū me nā'āpana o A252 Stel Poka 2 Hāʻawiʻo DSAW i kekahi mau mea hou ma luna o nāʻano hana'ē aʻe, me nā wikiwiki maikaʻi loa, a me nā wikiwiki kiʻekiʻe. E hōʻoiaʻiʻo i kahi paʻa ikaika ma waena o nā piptes, e ho'ēmi iā lākou i nā leʻa e pili ana i nā leaks, corrosion a me nā mea hōʻeha.

No ke aha e hoʻohana ai iā A252 SITARD 2 Steel Pipe no Sewer Project?
1 Mālama lākou i ko lākou hana i kahi ola lawelawe lōʻihi, e hōʻemi ana i ka pono no ka hoʻololi pinepineʻana a hoʻoponopono paha.
2.ʻO ka pale kauaʻana: A252 mau papa inoaʻo 2 i hoʻolālāʻia e nā kūlana i lalo o nāʻano, a me ka hoʻopunipuni a me ka hoʻopunipuni. Hoʻonui loa kēia hiʻohiʻona i ke ola lawelawe o nā pipes sewer.
3 ʻO kā lākou mau uku hoʻolimalima haʻahaʻa a me ka lōʻihi lōʻihi e hiki ai ke mālama i nā minonicalities a me nā mea hana pilikino i nā hana nui ma mua o ka manawa.
Ka noi o A252 Sente 2 Steel Pipe I Ke Kai Hana:
Ua hoʻohana nuiʻiaʻo A252 i kahi papa kīleʻa 2 i hoʻohana nuiʻia ma nāʻano likeʻole o nā hana hana socrastructors, me nā:
1. Ua hoʻohana nuiʻia nā'ōnaehana Municipal: A252 6 mau paila 2 kila i hoʻohana nuiʻia i ka hanaʻana i nā mea kanu o ke kaʻawaleʻana i nā mea kanu.
2.ʻO ka hoʻonohonohoʻana o kaʻenehana systeration: nā mea paʻakikī e koi ai i nā'ōnaehana subust e mālama i nā'ōnaehana ma ka hanaʻana i nā'āpana hana a me nā hale'ē aʻe. Hāʻawiʻo A252 SITED 2 SMALP PLAGE i ka ikaika pono a me ka wikiwiki no kēiaʻano o ka hoʻohanaʻana i kaʻoihanaʻoihana pūnaewele.
I ka hopena:
I ka hiki ana mailaina lainaKūkuluʻia,ʻo A252 papa inoaʻo 2 Steel Pipe me nāʻenehana Welding FailDing e hāʻawi aku i ka ikaika i hāʻawiʻia, ka hana nui a me ka hana holoʻokoʻa. ʻO kāna paleʻana o ka corrosion ma mua,ʻoi aku ka ikaika o ka ikaika a me ke kumukūʻai-kumukūʻai i kūpono i nā hana i nā hana inferastructor. Ma ka hoʻohuiʻana i kēia mau mea hana holomua a me nā kumu kumu, hiki i nā kūlanakauhale ke hoʻonui nui i ka ola a me ka hana hoʻomaʻemaʻe no nā mea āpau.
