NSW: Mea Hana Kiwikā Pōpō Weld i Hōʻoia ʻia
Ma ke ʻano heUa hōʻoia ʻia ʻo ISO 9001 a me API 6Dmea hana kiwikā poepoe hoʻoheheʻe, hāʻawi ʻo NSW:
- Pae Kūlike ʻole: nā kiwikā ½” a i 60″ (ANSI 150 – 2500)
– Kuʻihao Kūikawā:
– Kuʻihao Orbital no nā noi nukelea
– Lapaʻau Cryogenic (-320°F/-196°C)
- Ka hiki ke hoʻopaʻa wela
– ʻIke loea i nā mea:
– ASTM A351 CF8M kila kila
– Alloy 20, Hastelloy, titanium
– Nā koho PTFE/PFA i hoʻopaʻa ʻia
– Kaʻina Hoʻāʻo:
– 100% hoʻāʻo ʻana i ka leaka helium
– Nā hoʻāʻo noho API 598
– Nā hoʻokuʻu mahuka (ISO 15848-1)
