2. E mālama i kahi anuanu, maloʻo a me kahi ea no ka mālama ʻana, a i ʻole e popo ma mua o ke kau ʻana. No nā pūʻolo nui/kaumaha, e ʻoluʻolu e hahai pono i nā lula hoʻouna kūloko.
1. He aha nā paila paipu kila ASTM A252 Grade 3?
Nā paila paipu kila ASTM A252 papa 3ua hoʻopaʻa ʻia nā paipu kila kūkulu no ka hoʻohana ʻana ma ke ʻano he kākoʻo kumu hohonu ma lalo o nā hale, nā alahaka, nā awa, a me ka ʻenekinia kai. ʻElua mau kaʻina hana hoʻopaʻa no kēia mau paipu: helical submerged arc welding pipe (SSAW) a i ʻole ka longitudinal submerged arc welding pipe (LSAW/EFW).
2. He aha nā nui a me nā lōʻihi e loaʻa ana?
Anawaena waho: 219 mm - 3000 mm (Loaʻa ka nui o ke anawaena XXL/nui) Mānoanoa o ka paia: 6-40 mm. ʻO ka lōʻihi maʻamau he 6 mika a me 12 mika, a hiki ke hāʻawi ʻia nā lōʻihi kūikawā ma ke noi.
3. He aha nā kūlana mea a me nā waiwai mechanical?

Ikaika Hua: ≥345 MPa
Ikaika tensile: 455 ~ 620 MPa
Elongation: ≥20%%
4. Hiki iaʻu ke loaʻa nā hōʻike hōʻoia maikaʻi a me nā hōʻike nānā?
ʻAe, ua hōʻoia ʻia nā paila paipu kila a pau e ISO 9001. ʻO nā palapala āpau e pono ai, me nā hōʻike ʻaoʻao ʻekolu mai ka SGS, BV a i ʻole kekahi kino ʻē aʻe i ʻike ʻia.
5. Pehea e hoʻopili ʻia ai nā paila paipu kila?
Hoʻopili i nā paila paipu kila me ke kāʻei kila a hoʻokaʻawale ʻia e ka poloka lāʻau me ka ʻole o ka hōʻino. Manaʻo ʻia nā uhi pale/ʻōwili a i ʻole/a me nā hana ʻili i ʻōlelo ʻia ma luna e like me ka hoʻopili ʻana o ka hoʻouna. Loaʻa ka hoʻopili pilikino.
6. He aha ka manawa hoʻouna?
Ka manawa hoʻouna: 15-30 mau lā ma hope o ka hōʻoia ʻana o ke kauoha (e pili ana i ka nui, nā kikoʻī a me ka hopena).
7. Hiki paha i nā nui maʻamau?
ʻAe, hiki ke hoʻopilikino ʻia ke anawaena, ka mānoanoa o ka paia e like me nā koi kikoʻī o nā mea kūʻai aku.
