I kēia mau lā iho nei, ma ka hale hana hoʻopili o Jinbin, nui ke anawaenakiwikā poepoe kuʻihaoua kau ʻia. Hana ʻia kēia mau kiwikā pōpō a pau me ka mea Q235B a ua lako me nā mea hana huila lima. He nani a like nā wili, me ka ʻole o ka leakage ma hope o ka hoʻāʻo ʻana. Loaʻa nā nui mai DN250 a i DN500. I kēia manawa, ua hana ʻia kekahi o lākou. 

ʻO ke kila kalapona nui-anawaenakiwikā poepoeLawe ia i ke kila kalapona maʻamau Q235B ma ke ʻano he mea nui a hoʻohui i nā pono piha o ka hoʻonohonoho ʻana o ka bore o nā valves pōpō. He mea wehe a pani ia no nā pipelines nui a me ke kaomi haʻahaʻa, kūpono no nā pipelines me ka bore inoa o DN300 a ma luna. Hoʻomaopopo ia i ka pono a me ka hoʻokele waiwai a ʻo ia ke koho nui no ka lawe ʻana i nā pāpāho maʻamau ma nā kahua kūlanakauhale a me nā ʻoihana. 

ʻO nā waiwai o ke kila kalapona haʻahaʻa Q235B e komo pū me ka plasticity maikaʻi loa a me ka hana kuʻihao. Hiki ke hoʻokumu ʻia nā kino valve anawaena nui ma ke kiola ʻana a i ʻole ka kuʻihao ʻana. He maʻalahi ka ʻenehana hana, a ʻoi aku ka haʻahaʻa o ke kumukūʻai hana ma mua o ke kila alloy. He kūpono ka mālama ʻana ma hope. Hoʻohana ka valve pōpō motorized i kahi ʻano wehe a pani pōpō. ʻAʻohe hōʻemi i ke anawaena o ke ala, a he liʻiliʻi ke kūʻē i ke kahe waena. He maʻalahi ke wehe a pani a he kiʻekiʻe ka hana ma lalo o nā kūlana hana anawaena nui. Ua lako ka ʻili sila me ka hoʻopili pale ʻaʻahu, e hōʻoiaʻiʻo ana i ka sila hilinaʻi ma lalo o nā kūlana hana maʻamau. Eia kekahi, hiki ke mālama ʻia ke kino valve me ka uhi anti-corrosion ma ka ʻili e hana no ke kūʻē ʻana i ka corrosion maʻamau o Q235B, a kūpono no nā mea ʻaʻole corrosive.（Calbon Steel Flanged Ball Valve） 

ʻO kāna mau noi kikoʻī e kālele nui ʻia ana i nā paipu halihali o ke kaomi waena a me ka haʻahaʻa, nā kahe nui, a me nā media non-corrosive, me kahi noi koʻikoʻi ma ka pūnaewele lako wai nui o ke kūlanakauhale a me nā kikowaena pamu nui o nā papahana lako wai a me ka hoʻokahe wai o ke kūlanakauhale. ʻO ka hoʻomehana kikowaena kūlanakauhale a me ka hale nui HVAC e hoʻopuni ana i nā ʻōnaehana wai ma ka ʻoihana HVAC a me ka hoʻomehana; ʻO nā paipu wai e hoʻopuni ana i ka ʻoihana a me nā paipu wai hoʻoluʻu i nā ʻoihana e like me ke kila, ka mana a me nā ʻoihana kemika ma ka ʻāpana ʻoihana, a me nā paipu halihali haʻahaʻa no nā huahana aila i hoʻomaʻemaʻe ʻia a me nā huahana aila maʻamau; Pili nō hoʻi ia i ka wehe ʻana a me ka pani ʻana o nā paipu anawaena nui a me ka hoʻoponopono kahe ʻana o nā media kōkua e like me ka wai maʻemaʻe haʻahaʻa a me ke kinoea i nā ʻoihana e like me ka metallurgy a me ka mining. 

Ma ke ʻano he mea hana valve ʻoihana, he 20 mau makahiki o ka ʻike hana a me ka hana ʻana o Jinbin Valve. Hoʻohiki mākou i ka maikaʻi a hana me ka pono. Inā he mau pono valve pili kāu, e waiho i kahi leka ma lalo a e loaʻa iā ʻoe kahi pane i loko o 24 mau hola!
