Ka ikaika a me ka paakiki.

Histm a252criral i welded filal pipei hanaʻia ma ke kila kiʻekiʻe kiʻekiʻe e hālāwai ai me nā kūlana Astm Astm A222. Hōʻoiaʻiʻo ka hana maʻamau i ka ikaika a me ka lōʻihi o nā paipu, e hana ana iā lākou no nāʻano o nā noi a me nā meaʻona a me ka waiʻona. Hoʻonui ka FIReles i ka ikaika a me ke kū'ēʻana i nā pipes i waho o nā hana o waho, e hōʻoia i nā kūlana kiʻekiʻe.

ʻO ka hana kūpono kūpono a me ke kumukūʻai-kūpono:

ʻO kekahi o nā mea mua o ka waiwai mua o ka Astm Astm A252 Spiral Welded Steel Peaffien ka hana maikaʻi loa ma ka hoʻonohonohoʻana a me ka hoʻohanaʻana. He maʻalahi keʻano o kāna hana spiral e halihali a lawelawe ma muli o kona kaumaha māmā i hoʻohālikelikeʻia i nā mea hou aʻe. Hoʻohuiʻia, ka hoʻokaʻawaleʻana o kēia mau paipai i ka piʻiʻana o nā pipes, e hōʻemi ana i nā koi no nā kūpono a me nā pū. ʻAʻole wale kēia hana i kēia manawa, ua hōʻemiʻia ia he uku no ka hoʻomohalaʻana, hana i kēiaʻano hana likeʻole no kaʻanoʻoihana kālā.

ʻO ka pākaukauʻo Spiral Flall i ka heluʻana o ka lōʻihi

E hoʻonui i ka paleʻana o Corrosiod:

He pilikia nui ka pilikia ma nā'ōnaehana piping,ʻoi aku ka hana ma nāʻoihana e mālama i nā mea kanu a me nā mea kanu corrostive. ʻO ka Astm Astm A252 e hōʻoia i ka hōʻoiaʻana i nā piptes spiral i hoʻopauʻia i nā pale cheel i hōʻikeʻia e ka cortsoce maikaʻi loa. ʻO kēia mau kipoki i nā pale pale e like me ka epoxy a iʻole zinc e hana ana i keʻano he corrive a me ka hōʻemiʻana i ko lākou ola. ʻO kēia hiʻohiʻona he pōmaikaʻi nui ia i lalo o nā noi a iʻole nā noi a nā koina e hōʻikeʻia ana i nā kūlana kūlohelohe.

Ka nui e lawe ana i ka hiki:

ʻO kekahiʻano mea koʻikoʻi o Astm Astm A252 Spiral Welded Steel Pail Pearl ʻO kaʻenehanaʻo Spiral Welling i hoʻohanaʻia i ka hana hana hana e hoʻonui ai i ka ikaika a me ka hiki ke hoʻomau i nā ukana kaumaha. Inā paha i hoʻohanaʻia ma Bridge kūkulu, nā kumu hana hoʻonohonoho a iʻole nā piptes i lalo, e hāʻawi ana i ka hopena o ka hopena o ka hopena o ka hopena.

ʻO ke kikowaena kaiāulu:

Ma kahi era i ka wā e pale ai ka paleʻana o ka honua, ke kohoʻana i nā mea waiwai kūpono e pili ana i nā mea waiwai kūpono. ʻO ka hukiʻana o ka pilaʻo spined i ka pipala astm astm a2002 mau koi me nā hana kūkulu hale ma muli o kona mau hana a me ka recyclability.

I ka hopena:

Ua hoʻopauʻo Spiral Guil Pipe PPEPE Astm A222 i kaʻoihana piping i kona ikaika ikaika, i ka ikaika ikaika a me ke kumukūʻai. ʻO kēia mau paipai e hālāwai ai a iʻole ma mua o nāʻoihana o nāʻoihana, e hana ana iā lākou i ke koho mua ma nāʻoihana he nui. ʻO kāna hana ikaika loa e lawe ana i ka paleʻana a me ka corrosioni e hōʻoia i ka hoʻomohalaʻana i ka hana o nā hana infrastructure a hāʻawi i ka holomua o kaʻoihana honua. Ma ka hoʻohanaʻana i kēia mau piptes, hiki i nā papahana kūkulu ke koho i ka pono, e hōʻemi i nā uku a hōʻoia i ka hilinaʻi lōʻihi.
