ʻO ka paipu kila kalapona ASTM A672 B60/B70/C60/C65/C70 LSAW(JCOE)hoʻohana ʻia i ke kūlana kiʻekiʻe-kaomi a hoʻohana nui ʻia i ka mea kanu mana, ka ʻoihana aila ma waho, ka ʻoihana kemika, Fertilizer, petrochemicals, refineries etc.
ʻO ka Paipu Kila Kalapona ASTM A672 B60/B70/C60/C65/C70 LSAW(JCOE) he mau wili i hoʻopili pālua ʻia, he wili komo piha i hana ʻia e like me nā kaʻina hana a e nā mea hoʻopili a i ʻole nā mea hana wili i kūpono e like me ke ASME Boiler and Pressure Vessel Code, Māhele IX.
Pono e mālama ʻia nā papa āpau ma waho aʻe o 10, 11, 12 a me 13 i loko o ka umu i kāohi ʻia a hiki i ±15℃ a e hoʻolako ʻia me kahi hydrometer hoʻopaʻa leo i loaʻa ai nā moʻolelo hoʻomehana.
Hana ʻana:ʻO ka hoʻoheheʻe ʻana o ke arc i hoʻokomo ʻia i loko o ka wai (LSAW).
Nui:OD: 406～1422mm WT: 8～60mm.
Papa:B60, C60, C65, a pēlā aku.
Lōʻihi:3-12M a i ʻole ka lōʻihi i kuhikuhi ʻia e like me ka mea e pono ai.
