ʻO ka pāpale ka hoʻopaʻa paʻa ʻana o ka ʻīpuka i hoʻopaʻa ʻia a hiki i ka API 600. Lawe ʻo ia i ka pahu mea hoʻopiha, ka pahu bolting flange, a me ka noho hope - a pono e hoʻolei maʻemaʻe, mīkini pololei, a hele i ka hoʻāʻo hydrostatic me ka leakage. ʻAʻole ia he pilikia hoʻonaninani ka porosity i loko o ka hoʻolei ʻana i ka pāpale: he ʻāpana i ʻoki ʻia i ʻike ʻia i ka manawa ʻino loa, ma hope o ka hoʻolilo ʻana i nā hola mīkini.
ʻO kēia ke kumu e hana ai nā mea hana valve i nā bonnets kumu mai Ningbo Ruican. Hoʻokumu mākou i nā pāpale kīpē puka ma ASTM A216 WCB kalapona kila (me WC6, WC9, CF8M, a me CF8 mau koho stainless) ma o ka hoʻolei kālā ʻana, e hāʻawi ana i nā hoʻoheheʻe paʻa paʻa me ka hoʻopau maikaʻi ʻana i ka ʻili o ka pahu pahu. ʻO ke kaʻina hana ʻupena kokoke e hōʻemi i ka haʻawina machining ma ka flange, gland region, a me ka gasket face, e hōʻemi ana i ka manawa mīkini a me ka ʻōpala waiwai i hoʻohālikelike ʻia me nā pāpale one-hoʻolei.
Ma hope o ka hoʻolei ʻana a me ka hana maʻamau, ua paʻa ka mīkini ʻo CNC - he alo flange, hoʻokiʻekiʻe ʻia ke alo (125–250 µin AARH serration no ASME B16.5), pahu pahu pahu, noho hope, a me nā puka stud - me nā polokalamu CNC i laka ʻia i kāu mau kiʻi. Hiki ke hāʻawi ʻia nā mea hoʻoheheʻe i hoʻāʻo ʻia, NDE-examined (RT/UT/MT no kēlā me kēia ASME B16.34 koi hou), a kākau ʻia me EN 10204 3.1 palapala hōʻoia a me ka traceability wela piha.
