Paipu kila ASTM A252 Papa 1/2/3 LSAW | Paipu kila kumu anawaena nui OD 508-1422mm

Wehewehe Pōkole:

ʻO nā paipu kila LSAW, e kūlike ana me nā kūlana ASTM A252, he mau paila paipu kila ikaika kiʻekiʻe, anawaena nui e kūpono no ka ʻenekinia kahua, ke kūkulu ʻana i ke alahaka, ka ʻenekinia moana, a me nā papahana ʻoihana kaumaha. Hāʻawi nā paipu kila LSAW i ke ʻano kūkulu maikaʻi loa, ka hiki ke hoʻopili maikaʻi ʻia, a me ka hiki ke hāpai i ka ukana, e kūpono ai no nā noi kahua hohonu. Loaʻa nā anawaena o waho mai 508 a 1422 mm. Hoʻolālā ʻia kēia mau paipu kila LSAW e like me nā kikoʻī a me nā kūlana o ka ʻoihana o kēia manawa, e hōʻoiaʻiʻo ana i ka ikaika kiʻekiʻe, ka mānoanoa like o ka paia, a me ka lōʻihi o ke kūpaʻa ʻoiai ma nā ʻano lepo ʻino a me ka wai paʻakai.

He kūpono kēia mau paipu kila LSAW no nā kumu paila alahaka, nā kikowaena awa, nā kahua kai, nā kumu hale kiʻekiʻe, a me nā ʻoihana ʻoihana. ʻO ka laulima ʻana me nā ʻoihana EPC akamai he nui a me nā hoʻonā hale honua e hōʻoiaʻiʻo ana i ko lākou ola lawelawe lōʻihi, ke kūpaʻa kiʻekiʻe i ka pala (me nā uhi koho), a me ka maʻalahi o ke kau ʻana.

E mālama i kahi anuanu, maloʻo a me ka ea maikaʻi, e pale i ka popo ma mua o ke kau ʻana. ʻO ka ukana nui a me ke kaumaha nui e ʻoluʻolu e hoʻokō i nā lula hoʻouna kūloko.

Nā nīnau i nīnau pinepine ʻia

1. Nā noi paipu kila ASTM A252 Papa 3?

Hoʻohana nui ʻia nā paipu kila ASTM A252 Grade 3 LSAW no ke kūkulu ʻana i ke kahua hohonu i nā hana kūkulu hale, e like me nā hale, nā alahaka, nā awa, ma waho o ke kai, a pēlā aku.

2. Pehea ka ʻokoʻa o ka Papa 1, Papa 2 a me Papa 3?

Hāʻawi ia i ka ikaika maikaʻi loa a me ke kūpaʻa o 3 mau papa, no laila kūpono ia no nā kumu kaumaha, a me nā ʻenekinia moana.

3. He aha ka meaPaipu kila LSAW?

Hoʻololi ʻia mai ka ʻike loea o nā kila, ʻo ka paipu LSAW kahi huahana paipu i hana ʻia ma ke kūkulu ʻana a me ka hoʻopili ʻana i nā papa kila longitudinal, i kapa ʻia hoʻi ʻo "longitudinal weld steel pipe".

4. He aha nā nui a me nā mānoanoa e loaʻa ana?

Loaʻa nā anawaena i loaʻa he 2 mai OD 406 mm a i 2500 mm a ʻo ka mānoanoa o ka paia mai 6 mm a 60 mm e kūpono no ke kahua kaumaha a me nā hana kūkulu moana.

5. Hiki ke hoʻohana ʻia i nā papahana moana a me nā papahana ma waho o ka ʻāina?

ʻAe. Hoʻohana nui ʻia ia i ka mana makani ma waho o ke kai, nā pā kai, nā uapo, a me nā kahua moana, a me nā mea ʻē aʻe. Loaʻa iā ia nā uhi e like me ka epoxy, 3PE, ka sima sima no ka pale ʻana i ka palaho.
