API 602 Forged B381 Gr. F-2 Titanium Globe Valve

ʻO ka Titanium ka mea nui o nā valves alloy titanium. He metala hana kemika loa ia. Hōʻike maikaʻi loa ia i ka pale ʻana i ka corrosion i nā media corrosive. Hoʻokumu maʻalahi ka Titanium a me ka oxygen i kahi kiʻiʻoniʻoni passive oxide ikaika a paʻa ma ko lākou ʻili. I loko o ka nui o nā media corrosive koʻikoʻi, paʻa loa kēia papa o ka kiʻiʻoniʻoni oxide a paʻakikī ke hoʻoheheʻe. ʻOiai inā ua pōʻino, ʻoiai he lawa ka oxygen, hiki iā ia ke hoʻoponopono iā ia iho a hoʻoponopono hou.

ʻO ka mea metala titanium o nā kīwaha titanium he kūpaʻa maikaʻi a me ka hiki ke hoʻololi ponoʻī i ka wā i hoʻoheheʻe ʻia i loko o nā kiʻi ʻoniʻoni ʻoniʻoni i nā wahi ʻino loa. Hiki i kona ʻano ke pale i ka corrosion ikaika ma lalo o nā kūlana hana paʻakikī. Ke hilinaʻi nei nā kiwi Titanium i ke kūpaʻa kemika o ka kiʻiʻoniʻoni ʻokiʻoki passive ma ko lākou ʻili i loko o ka media corrosive e pale aku i ka corrosion i loko o ka hana. No ke kūʻokoʻa, oxidizing, a me ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa i nā kaiapuni media, ʻo ke kiʻiʻoniʻoni pasive oxide ponoʻī ke kūpaʻa maikaʻi. No ka hōʻemi ʻana i nā media corrosive me nā wela kiʻekiʻe a i ʻole nā ​​​​waiwai pH haʻahaʻa, i mea e hoʻomaikaʻi ai i ka paʻa ʻana o kā lākou kiʻiʻoniʻoni passive oxide, hiki ke hoʻohui ʻia nā mea hoʻopiʻi corrosion e like me ka ea, ka wai, nā ion metala kaumaha, a me nā anion, a hiki ke hoʻohui ʻia ka hoʻololi ʻana i ka ion a me ka mālama anodizing. e hoʻohana i ka hoʻomaikaʻi ʻana i ke kūpaʻa corrosion a me ka paʻakikī o ka ʻili o ka titanium i ka hōʻemi ʻana i ka media.

B381 Gr. ʻO F-2 globe valve ka mea maʻamau i hoʻohana ʻia no ka mālama ʻana i ka wehe a pani ʻana paha o ka wai a hoʻoponopono i ka nui o ke kahe o ka wai. Hana ʻia ia me ke kila forged a loaʻa ka ikaika kiʻekiʻe a me ka pale ʻana i ka corrosion. ʻO nā hiʻohiʻona koʻikoʻi o nā kīwaha honua kila forged me:
