He aha nā ʻokoʻa nui ma waena o ASME B16.5 a me ASME B16.47

ʻO ASME B16.5 a me ASME B16.47 ʻelua o nā kūlana maʻamau o ʻAmelika no nā flanges. Eia naʻe, ʻaʻole hiki i nā poʻe he nui ke hoʻokaʻawale i nā maʻamau ʻelua, no laila ke hoʻohana pinepine nei lākou i nā maʻamau ʻelua me ka hewa. E hoʻokaʻawale kēia ʻatikala ma waena o nā kūlana ʻelua.

ʻO ka ʻokoʻa nui ʻo ia ka ʻokoʻa o ka flange caliber i hoʻokomo ʻia i loko o kēlā me kēia kūlana.

Aia ka ASME B16.5 i nā ana o NPS1/2 i NPS24 (ʻo ia hoʻi 1/2 iniha a 24 iniha) ma lalo o ka papa kaomi CL150-CL2500;
ʻO ASME B16.47 ka maʻamau no nā flanges nui-diameter, me nā nui o NPS26 a i NPS60 ma lalo o ka papa kaomi Class75-Class900.
Ua māhele ʻia ʻo ASME B16.47 i ʻelua pūʻulu, ʻo ia hoʻi ka moʻo A a me ka pūʻulu B

E pili ana i ka ʻokoʻa ma waena o nā moʻo ʻelua:

ʻO ke kumu ASME B16.47 Series A ʻo MSS SP-44, a ʻo API 605 ke kumu Series B.
ʻO ka pūʻulu A ʻo ia ka flange anawaena nui, a ʻo ka Series B ka flange paipu
He moʻo: nā kī puka nui, ka liʻiliʻi
B moʻo: nā kī puka liʻiliʻi, ka nui

Ua like ka nui o ka paipu ma waena o A series a me B series, akā ʻokoʻa ka nui o ka pilina, pono e koho ʻia e like me ke kūlana maoli.
ʻO ka maʻamau, hoʻohana hou ʻia ka series B i nā pipeline, e like me SH3406 a me HG20615 ma Kina, mai ASME B16.47 B (AP1 605). Hoʻokumu nui ʻia ke koho i kā lākou pono hoʻolālā ponoʻī. Me ka ʻole o nā lula kūikawā, koho ʻia ka nui liʻiliʻi. Ma hope o nā mea a pau, he haʻahaʻa ke kumukūʻai.

Wahi a ka maʻamau o ASME B16.47, ua ʻike mākou he ʻelua wale nō ʻano flanges i nā huahana flange e pili ana i kēia maʻamau:welding neck flangeaflange makapō.

Eia kekahi mau kiʻi e hōʻike i ka maʻamau ASME B16.47 i nā kikoʻī. Manaʻo wau hiki iā ʻoe ke loaʻa ka pane pololei ma aneʻi.

American standard flange nui ASME B16.47 nui anawaena paipu kila flange maʻamau, American standard flange ua hoʻohana nui ʻia i nā lako lawe ʻia mai a i ʻole nā ​​ʻoihana ʻē aʻe. Nā kūlana hoʻokō flange maʻamau maʻamau o ʻAmelika: ANSIB16.5, ASME B16.47, hōʻike ʻia ka caliber flange maʻamau ʻAmelika ma nā iniha (e laʻa me 1 “1-1/2″, 2 “3″, “, 8″, 10,12 “, 1416″, 18″, 20″ 24 “28″ 8, etc.) Ua kaha 'ia ka helu pumehana flange ma'amau me 6 mau papa kaomi, oia hoi ka Papa 150; Papa 300; Papa 600; Papa 900; Papa1500; ʻO ka papa 2500 American standard flange kahi ʻāpana e hoʻopili ai i nā paipu a me nā paipu, i hoʻopili ʻia i ka hopena paipu. ʻO ka pilina Flange a i ʻole ka hui flange e pili ana i ka mīkini hoʻopili hiki ke hoʻopili ʻia e ka flange, gasket a me ka bolt ma ke ʻano he hui o ka hui hoʻopaʻa ʻana. ʻO ka American standard flange nui ASME B16.47 nui anawaena paipu kila flange standard ua hoʻonohonohoʻia a hāʻawiʻia e Ningbo Xinggang Pipeline Equipment Co., Ltd. ʻO kā mākou hui kūikawā i ka hanaʻana a me ka hanaʻana i ka flange standard American, slip-on flange (S0), welding neck flange (WNF), flange wili NPT), ʻAmelika maʻamau i uhi i ka flange makapō, Class series carbon steel and stainless steel American standard flange.
