1. He aha ke kaomi inoa PN (MPa)?
ʻO ka waiwai kuhikuhi e pili ana i ka hiki ke kū'ē i ke kaomi o nā ʻōnaehana paipu e pili ana i ka hoʻolālā i hāʻawi ʻia i ke kaomi e pili ana i ka ikaika mechanical o nā ʻāpana paipu.Hōʻike pinepine ʻia ke kaomi nominal e PN.
(1) Nominal Pressure - ka ikaika compressive o ka huahana ma ka mahana kuhikuhi, i hōʻike ʻia ma PN, ʻāpana: MPa.
(2) Hōʻike wela: Loaʻa i nā mea like ʻole nā mahana kuhikuhi.No ka laʻana, ʻo ka mahana kuhikuhi o ke kila he 250°C
(3) Nominal pressure 1.0Mpa, hōʻike ʻia me: PN 1.0 Mpa
2. He aha ke kaumaha o ka hana?
E pili ana ia i ke kaomi kiʻekiʻe i kuhikuhi ʻia e like me ka wela hana kiʻekiʻe o ka pipeline i lawe ʻia ma nā pae āpau no ka palekana o ka ʻōnaehana pipeline.Hōʻike ʻia ke kaomi hana ma Pt.
3. He aha ke kaomi hoʻolālā?
E pili ana i ke kaomi koke o ka ʻōnaehana paipu wai e hana ana ma ka paia o loko o ka paipu.ʻO ka maʻamau, hoʻohana ʻia ka huina o ke kaomi hana a me ke koena hammer wai.Hōʻike ʻia ke kaomi hoʻolālā ma Pe.
4. Pumi hoao
ʻO ke kaomi e hiki ai ke hōʻike ʻia no ka hoʻāʻo ʻana i ka ikaika compressive a me ka hoʻopaʻa ʻana o ka ea o nā paipu, nā ipu a i ʻole nā mea hana.Hōʻike pinepine ʻia ke kaomi hoʻāʻo ma Ps.
5. ʻO ka pilina ma waena o ke kaomi inoa, ke kaomi hana a me ke kaomi hoʻolālā
ʻO ke kaomi nominal he kaomi nominal i kuhikuhi ʻia no ka maʻalahi o ka hoʻolālā, hana a hoʻohana.ʻO ka ʻāpana o kēia kaomi inoa he kaomi maoli, a he inoa maʻamau ka kaomi ma ka ʻōlelo Kina, a ʻo ka ʻāpana "Pa" ma kahi o "N".Nominal pressure in English is nominal pres-surenomina: l i ka inoa a i ʻole ke ʻano akā ʻaʻole i ka ʻoiaʻiʻo (nominal, nominal).ʻO ke kaomi inoa o ka moku kaomi e pili ana i ke kaomi inoa o ka flange o ka moku kaomi.Hoʻokaʻawale ʻia ke kaomi nominal o ka flange moku kaomi i 7 mau māka, ʻo ia hoʻi 0.25, 0.60, 1.00, 1.60, 2.50, 4.00, 6.40MPa.Pumi hoʻolālā = 1.5 × kaomi hana.
Loaʻa ke kaomi hana mai ka helu hydraulic o ka pūnaewele paipu.
6. Pilina
Pumi ho'āʻo> kaomi nominal> kaomi hoʻolālā> kaomi hana
Pumi hoʻolālā = 1.5 × kaomi hana (maʻamau)
