Gulu la zopopera mpweya za fiberglass reinforced plastic (FRP) zatha kupangidwa. Masiku angapo apitawo, zopopera mpweya izi zidapita kukayang'aniridwa mwamphamvu mu workshop ya Jinbin. Zidasinthidwa malinga ndi zosowa za makasitomala, zopangidwa ndi pulasitiki yopopera mpweya yagalasi, yokhala ndi miyeso ya DN1300, DN1400, DN1700, ndi DN1800. Zonse zili ndi zida zamagetsi komanso zogwirira ntchito pamanja. Pakadali pano, ogwira ntchito ku workshop adzaza gulu la gulugufeli ili.mavavu opopera madzindipo akuyembekezera kuwatumiza ku Indonesia.

Ubwino waukulu wa ma valve a mpweya a FRP uli mu kulemera kwawo kopepuka komanso mphamvu zambiri. Poyerekeza ndi zipangizo zachitsulo zachikhalidwe, kuchuluka kwake ndi kotala chabe la chitsulo, komabe kumatha kukhalabe ndi mphamvu zambiri, zomwe zimachepetsa kwambiri ndalama zogwirira ntchito ndi zipangizo panthawi yonyamula ndi kukhazikitsa. Pakadali pano, FRP ili ndi kukana dzimbiri kwabwino kwambiri.

Kaya m'madera a m'mphepete mwa nyanja omwe muli chinyezi komanso mvula kapena m'malo okhala ndi mpweya wambiri wa asidi ndi alkali, imatha kukana kukokoloka kwa nthaka, kukulitsa nthawi yake yogwira ntchito, ndikuchepetsa nthawi yokonzanso ndi kusinthira pambuyo pake. Kuphatikiza apo, chipangizochi chilinso ndi mphamvu zabwino kwambiri zotetezera kutentha komanso zoteteza mawu. Pakupuma mpweya, sichingoletsa kutayika kwa kutentha kokha komanso chimachepetsa mphamvu ya phokoso pa chilengedwe, ndikupanga malo abata komanso omasuka.

Mu makampani opanga mankhwala, ma valve a mpweya a FRP angagwiritsidwe ntchito kunyamula mpweya wowononga. Mu malo okonzera chakudya, chifukwa cha makhalidwe ake osawononga komanso opanda kuipitsa, amakwaniritsa miyezo ya ukhondo wa chakudya ndipo amatha kutsimikizira chitetezo cha malo opangira. Mu makina opumira mpweya m'malo oimika magalimoto apansi panthaka, sitima zapansi panthaka, ndi zina zotero, kulemera kwake kochepa komanso mphamvu zake zambiri zimapangitsa kuti zikhale zosavuta kuyika, ndipo kukana kwake dzimbiri bwino kumapangitsa kuti ikhale yoyenera malo okhala ndi chinyezi.

Mavavu a Jinbin amadziwika kwambiri popanga mavavu achitsulo, mavavu osiyanasiyana a mpweya opopera mpweya akuluakulu, mavavu a zipata, mavavu a gulugufe, mavavu owunikira, mavavu a penstock, ndi zina zotero. Tikhoza kusintha malinga ndi zosowa zosiyanasiyana. Pa mavavu a mafakitale ndi mavavu oyeretsera madzi, sankhani mavavu a Jinbin!
