I. Basic Product Category Knowledge Q&A (Zofunika Pakugula Zinthu Kunja)
1. Ndi mitundu iti yayikulu yosinthira kutentha kwa mafakitale? Kodi zochitika zawo zazikulu zogwiritsa ntchito ndi zotani?
1
- Zowotchera ma Shell ndi chubu: Izi zili ndi mphamvu zosunthika kwambiri m'mafakitale, zokhala ndi chipolopolo, machubu bundle osinthira kutentha, ndi pepala la chubu. Ndi zamphamvu, zolimba, -zosamva kutentha, -zopanda kutentha, komanso zimatha{4}}zosamva, zoyenerera-kupanikizika, -kutentha kwambiri, ndi{7}}zowonekera kwambiri. Amagwiritsidwa ntchito m'mafakitale olemera monga mafuta a petrochemicals, opanga magetsi, zitsulo,-makina akuluakulu a HVAC, ndi kupanga zombo zapamadzi, ndipo ndizomwe angasankhe pamapulojekiti akuluakulu{10}}akuluakulu akunja kwanyanja.

Zosinthira kutentha kwa mbale: Zopangidwa ndi zitsulo zosinthira kutentha kwazitsulo, ma gaskets, ndi zomangira, zimakhala ndi mphamvu zosinthira kutentha kwambiri, ndizophatikizika kukula kwake, ndipo ndizosavuta kusonkhanitsa ndi kupasuka. Iwo ndi oyenera sing'anga ndi otsika kuthamanga ndi sing'anga ndi otsika kutentha zikhalidwe ntchito ndipo chimagwiritsidwa ntchito chakudya ndi chakumwa, mankhwala, HVAC, makampani kuwala, mankhwala madzi ndi mafakitale ena. Ndiwo gulu lodziwika bwino la malonda ang'onoang'ono ndi apakati-azamalonda akumayiko akunja.

Mpweya-chozizira kutentha kwa mpweya: Kugwiritsa ntchito mpweya ngati kozizirirako, sikufuna madzi, kumapangitsa kukhala koyenera madzi-kumalo osowa komanso malo ogwirira ntchito kunja. Amagwiritsidwa ntchito m'mafakitale amafuta ndi gasi, malo opangira magetsi, madera akutali amigodi, ndi mapulojekiti ena akunja kwanyanja m'magawo osowa madzi-.
2. Kodi maubwino otani a zotenthetsera zomwe zimatumizidwa kunja poyerekeza ndi zida zopangidwa kuno?
- Kukhazikika kwadongosolo:Kuwotcherera kolondola komanso kukhwima kwa tchanelo kumawonetsetsa kuti kutentha kumasinthasintha, zomwe zimapangitsa kuti magetsi azikhala ochepa pakapita nthawi-ikugwira ntchito kwanthawi yayitali komanso kulephera kutsika kwambiri kuposa zida wamba zotsika{1}}zanyumba.
- Kusachita dzimbiri kwakuthupi:Pogwiritsa ntchito-zitsulo zosapanga dzimbiri, titaniyamu aloyi, ndi chitsulo chowirikiza kawiri, ndi yoyenera kuchitira zinthu za asidi ndi alkali komanso zowononga, zomwe zimapatsa moyo wautali komanso kutha kuzolowera kumayiko akunja.
- Miyezo yotsatiridwa bwino:Nthawi zambiri zimayenderana ndi miyezo yamakampani apadziko lonse lapansi, zimabwera ndi zikalata zonse zotsimikizira, kukwaniritsa zofunikira zovomerezeka zama projekiti ku Europe, America, Middle East, Southeast Asia, ndi mayiko ena.
II. Q&A pa Core Selection Parameters (Core Basis for Procurement)
1. Ndizigawo ziti zoyendetsera ntchito zomwe ziyenera kutsimikiziridwa posankha chowotcha chochokera kunja?
Pazinthu zonse zogulira malonda akunja, magawo asanu ofunikira ayenera kutsimikiziridwa pasadakhale kuti apewe kusankha kosagwirizana, kubweza, ndi kukonzanso. Zambiri ndi izi:
1
Zigawo zapakatikati: Mtundu wamadzimadzi otentha kapena ozizira (madzi, nthunzi, mafuta otumizira kutentha, asidi/ alkali solution, mafuta osapsa, ndi zina zotero), kuyika kwapakati, kukhuthala, kuwononga, kukulitsa, komanso kupezeka kwa zonyansa kapena tinthu tating'onoting'ono.
2
- Kutentha: Kutentha kolowera ndi kutuluka kwa zinthu zotentha ndi zozizira, kutentha kosalekeza, kukwera kovomerezeka, kusiyanitsa pakati pa machitidwe abwino ndi ovuta kwambiri.
3
- Zigawo za kupanikizika: Kuvotera kuthamanga kwa ntchito, mphamvu yothamanga kwambiri, kutsika kovomerezeka; chipolopolo-ndi-machubu akuyenera kukhala abwino-pazantchito zapakatikati.
4
Mayendedwe oyenda: Kuthamanga kwanthawi zonse kwapakati, pazipita / kutsika kusinthasintha kwamadzimadzi, kudziwa mwachindunji malo osinthira kutentha ndi miyeso ya zida.
5
Zomwe zimagwirira ntchito: Kugwira ntchito mosalekeza / kwakanthawi, kusinthasintha kwa katundu, malo oyika (m'nyumba / kunja, kowuma / konyowa, mpweya wowononga).
2. Kodi zifukwa zazikulu zosinthira mphamvu zosinthira kutentha ndi zotani?
- Kupatuka kwa magawo osankhidwa:Kusinthana kwa kutentha sikunawerengedwe potengera kuchuluka kwenikweni komwe kumagwirira ntchito, zomwe zidapangitsa kuti zida zocheperako zomwe sizingakwaniritse zofunikira pakuwotcha-zonse.
- Kufananiza kosayenera kwa tchanelo:Kuthamanga kwapakati sikugwirizana ndi njira yoyendetsera zipangizo, kuteteza madzi kuti asapange chipwirikiti chothandiza komanso kuchepetsa kwambiri kutentha kwa kutentha.
- Mavuto a makulitsidwe ndi kutsekeka:Sing'anga ndiyosavuta kukweza, koma zoletsa-zosintha sizinasankhidwe. Kugwira ntchito kwa nthawi yayitali-kumapangitsa kuti ma plates achuluke komanso ma chubu bundle, zomwe zimalepheretsa kutentha.
- Zolakwika pakuyika ndi kutumiza: Kulumikiza mapaipi olowera ndi kutulutsa kapena kuyika zida zopendekeka kumabweretsa kugawa kwamadzimadzi komanso kuchepetsa kugwiritsa ntchito kutentha.
III. Q&A Yosankha Zinthu Zofunika (Kiyi ku Kukaniza kwa Corrosion ndi Moyo Wautumiki)
Kodi ndi zinthu ziti zomwe zimagwiritsidwa ntchito nthawi zambiri komanso njira zoyenera zowonera pazosinthira kutentha kuchokera kunja?
Nambala yathu yaulere yaulere: 400-1234-567
1
- 304 Chitsulo Chosapanga dzimbiri: Chachikulu-chinthu chodziwikiratu, chosagonjetsedwa ndi madzi abwinobwino komanso ma acid ndi ma alkali, oyenera HVAC, kuthira madzi wamba, komanso njira zosinthira kutentha kwamadzi. Mtengo wapamwamba-chiŵerengero cha kagwiridwe ka ntchito, chisankho choyamba pamaoda otumizidwa nthawi zonse.
2
- 316L Chitsulo Chosapanga dzimbiri: Kusachita dzimbiri bwino kuposa 304, kusagwirizana ndi ma chloride ayoni ndi asidi pang'ono ndi dzimbiri la alkali, oyenera madzi a m'nyanja, chakudya ndi chakumwa, mankhwala, ndi zinthu zowononga zinthu mopepuka.
3
- Chitsulo cha Duplex: Champhamvu kwambiri komanso chosachita dzimbiri, choyenerera ayoni wa kloridi wambiri, mchere wambiri, komanso zinthu zowononga pang'ono, zomwe zimagwiritsidwa ntchito popanga uinjiniya wam'madzi ndi ntchito zamadzi otayira amadzimadzi.
