Ma ke kahua o ka hana valve, ʻo ka maikaʻi ke ola mau o nā ʻoihana. I kēia mau lā, ua hana kā mākou hale hana i ka hoʻāʻo ʻana i ka ʻāpana magnetic ma kahi pūʻulu okīwī lele leleme nā kikoʻī o DN1600 a me DN1200 e hōʻoia i ka welding valve kiʻekiʻe a hāʻawi i nā huahana hilinaʻi no nā mea kūʻai.

ʻO DN1600 a me DN1200 nui-diameter butterfly valve pneumatic he hana koʻikoʻi i nā ʻoihana ʻoihana. Hoʻohana pinepine ʻia kēia mau valve no ka lawe ʻana i ka nui o ka media wai, a pili pono ko lākou maikaʻi i ka hana palekana a paʻa o ka ʻōnaehana holoʻokoʻa. No ka hōʻoia ʻana i ka maikaʻi o ka welding, ua hoʻohana mākou i ka ʻenehana nānā ʻana i nā ʻāpana magnetic.

（MT）He ʻano hoʻāʻo ʻino ʻole ka nānā ʻana i ka ʻāpana magnetika e hiki ke ʻike pono i nā hemahema o ka ʻili a kokoke i ka ʻili i nā wahi wili valve. I ka wā o ka nānā ʻana, hoʻoheheʻe ʻia ka pauka magnetic ma luna o ka ʻili o kaductile iron butterfly valves, a laila hoʻohana ʻia ka māla magnetic e hōʻiliʻili i ka pauka magnetic ma ka pūnaewele defect, e hana ana i nā māka magnetic maopopo, a laila e hoʻoholo pololei ai inā he mau māwae, pores, slag inclusions a me nā hemahema ʻē aʻe i ka wahi wili.

Ke hana pono nei nā limahana ʻenehana o kā mākou hale hana e like me nā kūlana hoʻāʻo a me nā kaʻina hana me ka manaʻo kiʻekiʻe o ke kuleana a me ka ʻuhane ʻoihana. Hoʻoponopono pono lākou i ka ikaika o ke kahua magnetic a me ka nui o ka pauka magnetic i hoʻopaʻa ʻia e hōʻoia i ka pololei a me ka hilinaʻi o nā hopena hōʻike. E hoʻopaʻa ʻia a hoʻopaʻa ʻia nā hemahema i ʻike ʻia, a e hana ʻia nā hana hoʻoponopono kūpono a hiki i ka hoʻokō pono ʻana o ka valve butterfly 1200mm i nā koi maikaʻi.

Ma o kēia ho'āʻo ʻike ʻike ʻana i nā ʻāpana magnetic valve ikaika, ʻaʻole mākou i hōʻoia i ka maikaʻi wili o kēia pūʻulu o ka nui-diameter.kiwi lele lele, akā hoʻomaikaʻi hou i ka maikaʻi o ka huahana a me ka hoʻokūkū mākeke o kā mākou hale hana. E hoʻomau mākou i ka manaʻo mana o ka mana o nā kūlana kiʻekiʻe a me nā koi koʻikoʻi, e hoʻomau mau i nā kaʻina hana hana a me nā ʻano hoʻāʻo, hāʻawi i nā mea kūʻai aku i nā huahana valve kiʻekiʻe kiʻekiʻe, a hāʻawi i ko mākou ikaika ponoʻī e hāpai i ka hoʻomohala ʻana o ka ʻoihana.
