ʻO ka Stainless Steel Check Valve Seat kahi mea hoʻopaʻa hoʻopaʻa pololei e hāʻawi ana i ka ʻili pili koʻikoʻi no ka disc valve check a i ʻole ka pōleʻa, e hōʻoia ana i ka pani maikaʻi a me ka pale ʻana i ka hoʻihoʻi ʻana i nā ʻōnaehana pipeline. Pono ka noho valve e pale i ka erosion, corrosion, cavitation damage, and galling oiai e malama ana i ke ano paa ma lalo o ke kaomi a me ke ana wela. Hoʻopili pololei ka hoʻopau ʻana o ka ʻili ma ke kikowaena sealing i ka leak-tightness a me ke ola pōʻai valve.
Hana ʻo Ningbo Ruican i nā noho pahu kila kila me ka hoʻohana ʻana i ke kaʻina hana hoʻolei kālā silica sol, e hana ana i nā noho me ka maikaʻi o ka ʻili, ka mānoanoa o ka paia, a me nā kiʻi paʻakikī o loko. ʻO ke ʻano o ka hoʻolei kālā ʻana ua kūpono loa ia no nā mea hoʻoheheʻe kūʻokoʻa e like me CF8M (316 stainless), CF3M (316L stainless), a me nā māka stainless duplex, he mea paʻakikī ke hoʻohana ʻia mai ka lāʻau paʻa paʻa a hiki i ka hana paʻakikī.
Ma hope o ka hoʻolei ʻana, ʻo kēlā me kēia noho valve ka pololei CNC machined a lapped no ka hoʻokō ʻana i ka palahalaha ʻili a me ka ʻili o ka ʻili. Loaʻa i kā mākou hiki ke hoʻopaʻa ʻia i loko o ka hale i ka hoʻopaʻa ʻana i ka palahalaha o ka ʻili i loko o 2 mau kaha māmā (0.0005 mm), e hōʻoia ana i ka pani paʻa ʻana o ka hū ma kēlā me kēia API 598 a me MSS-SP-61 mau kūlana hoʻāʻo. Hoʻolako mākou i nā mea hana valve, pipeline EPC contractors, a me nā mea hoʻolako ʻōnaehana wai ʻenehana ma ka honua holoʻokoʻa.
