Premagreg yopepuka siyongokhala ndi kutembenuka bwino kokha, komanso kutsutsana bwino kuphatikizika kwa Acids, alkalis, mchere komanso mphamvu zamakina mutachiritsa, monga Frp. Zinthu zabwinozi zimapanga kuwala kokhazikika kwa akasinja, matanki osungira ma petroleum, pamwamba-pansi ndi pansi pa mapaipi a anti-Contros.

Poyerekeza ndi kukonza kulumikizana, chifukwa plate yothirira imatha kulowa m'matumbo kapena mafilimu apulasitiki, ndipo pali mafilimu apulasitiki omwe ali pamtunda wapamwamba komanso wotsika kwambiri, zomwe zimathandiza kwambiri malo omanga ndi chitetezo. Kugonana. Plagre yothira bwino ndi yofewa ndipo imadulidwa molingana ndi zosowa za polojekiti kenako ndikuyigwiritsa ntchito mwachindunji. Amachiritsidwa ndi kuwala kwa UV. Nthawi yochirikiza ndi mphindi 10 zokha mpaka 20 zokha. Zimakhudzidwa ndi chilengedwe ndipo zitha kugwiritsidwa ntchito chaka chonse. Ntchito yomanga, imatha kuigwiritsa ntchito pochiritsa, kuchepetsa nthawi yomanga ndi ndalama zogwira ntchito.
Ku Petrochining chokot No. 3 Malo Okwerera, Precrep yokomedwa ndi Merican 9505 idagwiritsidwanso ntchito kukonzanso thanki yosungirako Mafuta. Zomangamanga zomangirazi zikuwonetsedwa mu chithunzi pansipa. Kuumitsa kumatha kufikira 60, ndipo kumatsutsana.

Kubowola kowongolera ndi njira yomanga pakapipi mu ukadaulo waukadaulo. Amagwiritsidwa ntchito kwambiri pantchito yomanga mafuta, gasi wachilengedwe komanso mapipu ena a muuni. Momwe mungatetezere chingwe chakunja chakunja cha ma piperiner Kubowola pobowola nthawi zonse kwakhala vuto m'munda wamapaipi omanga mapaipi. . Mapaipi ambiri osinthika amagwiritsidwa ntchito pobowola, ndipo kuuma kwa osanjikiza wa anti-cordor pamtunda sikokwanira. Pakangokoseka, anti-corros wosanjikiza nthawi zambiri amakhala osweka kapena m'mphepete mwa zinthu zomwe zimapangika kapena kuthyoledwa, zomwe zimakhudzanso mphamvu zotsutsa. Poona mavuto omwe ali pamwambawa, prepreki yopepukayo imatha kugwiritsidwa ntchito ngati chotchinga chakunja kwa mapaipi. Maonekedwe ake akulu ndi kuuma kwake, kukana matalala ndi kutsutsana ndi mikangano, komwe kumatha kuteteza osanjikiza.
Kufanizira kwa zotchingira zotchingira chitetezero chisanachitike komanso pambuyo pakugwiritsa ntchito mapaipi obowola oyendetsedwa ndi omwe akuwonetsedwa:
Zitha kuwoneka bwino kuchokera pakuyerekeza kuti predge yopepuka yopepuka ili ndi zotsatira zabwino zoteteza pa mapaipi ndikuwongolera magwiridwe antchito a masitepe.

Ambiri mwa akasinja osungira mafuta ndi mafuta ndi akasinja achitsulo. Chifukwa mafuta ndi mpweya nthawi zambiri zimakhala ndi zinthu zachilengedwe, kutukula kwa akasinja zachitsulo ndizofunikira kwambiri. Mwachitsanzo, pansi pa kutentha kwambiri mu thanki, mpweya woyipa monga kusungunuka mpweya, hydrogen sulfide ndi kuwononga mphamvu kwambiri pa thankiyo, yomwe imangoyambitsa kuwonongeka kwakukulu kwa tank, yomwe imangoyambitsa mafuta akuluakulu a mafuta ndi mpweya, komanso zimachulukitsa chitetezo. zoopsa zobisika. Pakugwiritsa ntchito akasinja osungira mafuta ndi mafuta, kukonza kwanu kapena kusintha kwa tank kumtunda kumafunikira pafupipafupi. Njira yachikhalidwe ya kukoka kwa tank padenga ndikusintha padenga lachitsulo chachitsulo, lomwe likufuna thankiyo kuti iyimitsidwe, kutsukidwa, ku dipatimenti yomanga kuti ivomerezetse zigawo. Nthawi yomanga ndi yayitali ndipo mtengo wokonza ndi wokwera. Komabe, pogwiritsa ntchito predging yopepuka, thanki yomwe ilipo imagwiritsidwa ntchito ngati template, ndipo yapangidwa ndikudulidwa pamalopo, ndipo imalumikizidwa ndi tank yoyamba yachitsulo pamwamba kuti apange zonse. Pamaziko osungira mphamvu zoyambirira za tank, mphamvu ya wosanjikiza imachulukitsidwa ndipo itha kugwiritsidwa ntchito ngati njira yatsopano yothandizira padenga la mafuta ndi mafuta osungira mafuta.
Kuphatikiza pa malo omwe atchulidwa pamwambapa, omwe atchulidwa pamwambapa amathanso kugwiritsidwa ntchito mu zingwe zotsutsana monga zingwe zokhala pansi pa nthaka, masitima osungirako zinyalala, ndikukonzanso chomera. Pakadali pano, ambiri mwa ma sheet owoneka bwino pamsika ndi zinthu zogulitsa kunja, ndipo mtengo wake ndi wokwera, womwe umalepheretsa ntchito yawo. Komabe, mothandizidwa ndi boma, chisamaliro cha msika, komanso kuchuluka kwazinthu zofufuzira ndi chitukuko, padzakhala mitundu yosiyanasiyana ya ma sketor schrew omwe amagwiritsidwa ntchito mu minda yosiyanasiyana.
