I kēia mau lā iho nei, he nuinā kiwikā makapō i pani ʻiaua hoʻopau ʻia ma ka hale hana o Jinbin Valve. Me ka nui o DN700, kaomi hana o PN10, ua hana ʻia lākou me ke kila kalapona Q235B.

ʻAno pani ʻiakiwikā maka aniani(ʻano kila kalapona DN700) hoʻokō i ka wehe ʻana a me ka pani ʻana o ka paipu ma o ka hoʻololi "wehe/makapō" o ka papa valve. I ka wā o ka hana, hoʻokuʻu mua ka mīkini hoʻokele i ka ʻili sila o ke kino valve, e ʻae ana i ka papa valve e neʻe pālahalaha e hoʻohālikelike i ka lua ma waena a i ʻole ka lua makapō me ka pipeline. Ke kau ʻia, hoʻopaʻa hou ʻia ka ʻili sila e hana i kahi hoʻokaʻawale zero-leakage. ʻAʻole pili pololei nā ʻili sila i ka wā e wehe ai a pani ʻia, e hōʻemi nui ana i ka ʻaʻahu a hōʻoia i ka sila hilinaʻi lōʻihi.

Ke hoʻohālikelike ʻia me nā kiwikā maʻamau, hiki iā lākou ke hoʻokaʻawale loa i nā paipu, e lawelawe ana ma ke ʻano he hōʻoia palekana koʻikoʻi no ka mālama ʻana i nā paipu e lawe ana i nā mea weliweli. He kūpono ka mea kila kalapona no nā mea kūlohelohe a nāwaliwali ka ʻino, e hāʻawi ana i ke kumukūʻai haʻahaʻa a me ka ikaika kūkulu kiʻekiʻe, e kūpono ai no nā noi nui e like me DN700. Eia kekahi, he liʻiliʻi ko lākou ʻaʻahu i ka wā o ka hana, kahi hale i hoʻopaʻa piha ʻia e hōʻemi i ka ʻino o waho no ke ola lawelawe lōʻihi, a kākoʻo i ka hana uila/hydraulic no ka mana mamao. Hoʻopau kēia i ka pono no nā limahana e hoʻopili pololei i nā mea weliweli, e kūpono ai lākou no nā hiʻohiʻona automation ʻoihana.

Hoʻohana nui ʻia kēia mau kiwikā i ka ʻoihana metallurgical no ka mālama ʻana i ka hoʻokaʻawale ʻana o nā paipu kinoea umu pahū a me ke kinoea umu coke, e pale ana i nā leaka kinoea ʻawahia a me ka hōʻoia ʻana i ka palekana o ka mālama ʻana i ka umu a me ka pūnaewele paipu. Hoʻohana pū ʻia lākou i nā kahua kemika a me ka palekana kaiapuni no ka wehe ʻana/pani ʻana i nā paipu e lawe ana i nā mea ʻawahia a me nā mea lapalapa/pahū e like me ke kinoea chlorine, ammonia, a me ke kinoea flue ʻoihana. Eia kekahi, lawelawe lākou ma ke ʻano he mau mea pani koʻikoʻi i nā ʻōnaehana kinoea o ke kūlanakauhale a me ka ʻoihana mana, ke kinoea flue, a me ka mālama ʻana i ka wai ʻino, i hoʻohana ʻia no ka mālama ʻana i ka ʻāpana pipeline a i ʻole ka hoʻokaʻawale ʻana i ka pilikia.

Ma ke ʻano he mea hana valve maʻamau no ka ʻoihana metallurgical, hana ʻo Jinbin Valve i nā ʻano valve makapō like ʻole, me nā valve makapō hāmama, nā valve makapō pani, a me nā valve makapō kiʻekiʻe, hiki ke hoʻopilikino ʻia e like me nā kūlana hana maoli. Inā he mau pono kūpono kāu, e ʻoluʻolu e waiho i kahi leka ma lalo a i ʻole e kelepona mai iā mākou ma o ka leka uila ma ka ʻaoʻao home, a e loaʻa iā ʻoe kahi pane i loko o 24 mau hola!
