ʻO kekahi pono o A252 Grade 3 paipu kila kona versatility.Loaʻa kēia mau paipu i nā ʻano nui a me nā mānoanoa, e kūpono ai i nā ʻano hana like ʻole.ʻO ke kūkulu ʻana i kahi liʻiliʻilaina ʻōpalaaiʻole kahi laina paipu aila nui, hiki ke maʻalahi ka paipu kila A252 Grade 3 e hoʻokō i nā koi o ka papahana.Eia kekahi, hiki ke hana ʻia kēia mau paipunā paipu hollow-section structural pipes, hoʻonui hou i kā lākou hoʻohana ʻana i nā hana kūkulu.

Ma waho aʻe o kona ikaika a me ka versatility, ʻike ʻia ka paipu kila A252 Grade 3 no kona kumukūʻai.He mea maʻalahi kēia mau paipu e hoʻokomo a koi aku i ka mālama liʻiliʻi, e hōʻemi ana i nā kumukūʻai o ka papahana holoʻokoʻa.Eia kekahi, ʻo ko lākou ola lōʻihi a me ka pale ʻana i ka corrosion e hōʻoia i ka hoʻihoʻi ikaika ʻana i ka hoʻopukapuka no ka sewer apaipu aila lainanā papahana kūkulu.

ʻO kekahi pono koʻikoʻi o ka paipu kila A252 Grade 3 ʻo ia kona kūlike me nā ʻano hana hana like ʻole.Hiki ke hoʻokomo ʻia kēia mau paipu me ka hoʻohana ʻana i nā ʻano hana ʻeli kuʻuna a i ʻole nā ʻano ʻauwaha ʻole e like me ka hoʻoheheʻe ʻana i ka ʻaoʻao, ka paipu jacking a i ʻole ka micro-tunneling.ʻO kēia maʻalahi e hiki ai ke hoʻokomo pono a me ke kumu kūʻai ma kahi ākea o nā kaiapuni paʻakikī, me nā wahi kaona, nā ala wai a me nā wahi pili i ke kaiapuni.

ʻO ka holoʻokoʻa, hāʻawi ka paipu kila A252 Grade 3 i nā ʻano pono like ʻole no ke kūkulu ʻana i ka paipu a me ka ʻaila.ʻO ko lākou ikaika, ka lōʻihi, ka versatility a me ka maikaʻi o ke kumukūʻai e kūpono iā lākou no kēia mau noi koi.Inā hoʻohana ʻia i loko o ka hoʻoheheʻe ʻana a i ʻole ka ʻaila pipeline, hāʻawi kēia mau paipu i ka hana hilinaʻi a me ka waiwai lōʻihi.ʻO ka hopena, ke noho nei lākou i ka hopena o ke koho no nā ʻenekinia a me nā mea hana ʻaelike e ʻimi nei i nā hopena paipu paʻa a hilinaʻi.

Mua: Nā paipu wiliwili ʻia no ka laina kinoea ma lalo o ka honua

Aʻe: Nā Pōmaikaʻi o ka hoʻohana ʻana i nā paipu kila kabone Spiral Welded
