Mak bilong makim ol samting em i as bilong
1. Korosen-}}risiten metal samting
Ol samting bilong steinles ain:Planti ol hai- kwaliti bal valv wantaim ol hanwil ol i wokim long steinles stiel, olsem 304, 316L na ol narapela model. Kisim 316L steinles stiel olsem eksampel. Em i gat molibdenam, we inap long sakim gut klorait korosen na i save mekim gut long kemikel, tritmen bilong solwara na ol narapela indastri. Olsem, taim ol kemikal kampani i save karim ol wara i save bagarapim ol samting i gat klorait aion, 316L steinles stiel bal valv inap wok gut inap longpela taim na daunim hevi bilong bagarap.
Ol spesel aloi:Long sampela ples i save bagarapim tru ol samting, olsem bikpela tempereja, bikpela presa na strongpela kondisen bilong korosen, ol spesel aloi olsem Hastelloy na Monel bai ol i makim. Ol dispela aloi i gat gutpela strong bilong daunim korosen na ol inap sanap strong long bagarap bilong ol kain kain strongpela asit na strongpela alkalis. Long proses bilong petrolium rifain, taim ol i wok wantaim ol midia i gat bikpela korosiv olsem bikpela konsentresen bilong haidrojen salfaid, ol bal valv ol i wokim long Hastelloy i ken lukim olsem sistem i wok gut.
2. Non-}long metal korosen-}}}}}risen samting
Ol plastik samting:Ol i save yusim ol plastik olsem politetrafluoetilen (PTFE) long siling pes, valv sia laining na ol narapela hap bilong ol bal valv. PTFE i gat gutpela kemikel stebiliti, em i no inap bagarap long korosen long klostu olgeta kemikel midia, i gat liklik friksen koefisen na gutpela siling. Long indastri bilong kaikai na dring, taim ol i givim ol samting i gat asid o alkaline kaikai long en, yusim ol PTFE-}}sil bal valv i no inap long mekim wok bilong givim wara tasol, tasol tu abrusim valv korosen na kontaminesen bilong medium. .
Ol samting bilong raba:Natural raba, kloropren raba, naitril raba na ol narapela raba materiel i gat gutpela tolerans long sampela korosiv midia insait long wanpela kain tempereja na presa rein, na planti taim ol i save yusim olsem gasket, O-ring na ol narapela siling komponen. Long wokim ol wara saplai na drenej sistem, raba-}sil bal valv inap long stopim wara long lik na sakim korosen long ol liklik kemikal insait long wara.
Tritmen we i stap antap i mekem se i gat proteksen
1.Kot proteksen
Metal koting:Long rot bilong sprei bilong thermal, elektroplating na ol narapela proses, wanpela leit bilong korosen-risen metal koting, olsem zinc na nikel koting, i karamapim antap long pes bilong bal valv. Thermal sprei zinc koting inap kamapim wanpela dens proteksen leit long pes bilong stiel bal valv, i save rausim gut ea na korosiv midia, kamapim gut korosen resistens bilong bal valv long atmosferik envairomen o liklik korosiv envairomen, na ol i save yusim planti long bal valv proteksen long ol ausait paiplain sistem. .
Non-′………′metalik kot:Ol oganik koting olsem epoksi koting na poliuretan koting inap givim gutpela korosen resistens. Epoxy koting i gat strongpela adhesen na gutpela kemikel korosen resistens, na inap lukautim gut pes bilong bal valv long erosen long asid, alkali na ol narapela midia. Long ol ples bilong tritim pipia, ol valv bilong bal ol i save yusim long karim pipia inap mekim sevis laip bilong ol i kamap bihain tru bihain long epoksi koting tritmen. .
2. tritmen bilong pasim
Pasivesen tritmen bilong ol steinles stiel bal valv inap kamapim wanpela moa stebol na dens oksait film long pes bilong en, na strongim korosen resistens bilong steinles stiel. Long taim bilong pasivesen proses, wanpela spesifik kemikel solusen i save wok wantaim pes bilong steinles stiel long mekim kromium element i kamap gutpela moa long pes, na kamapim strongpela pasivesen film, we i save stopim ol hevi olsem pitting korosen na krevis korosen bilong steinles stiel long taim bilong yusim.
Struktural disain i helpim long lukautim korosen
1. Optimisim siling straksa
Daunim ol spes na ol angle i dai pinis:Risenel disain siling straksa bilong bal valv long daunim wara retensen eria insait long valv na abrusim fomesen bilong krevis korosen. Olsem, ol i yusim wanpela gutpela bal na valv sia disain bilong larim wara i pas gut, na dispela i daunim hevi bilong namel deposisen na korosen insait long valv. Long ol kemikel paiplain, dispela optimais bal valv inap stopim ol midia i bagarapim ol long bungim ol spes na daunim probabiliti bilong korosen. .
Ol spesel samting bilong silim na ol straksa:Wanpela siling straksa wantaim wanpela self-}lining fanksen i yusim, wantaim korosen-}}resistant siling materiel, olsem yusim PTFE siling ring wantaim lip straksa long sampela bal valv, we i no inap long strongim tasol siling pefomens, tasol tu skrap impurities long pes bilong bal long taim bilong valv opening proses long adherim long adhering i go long pes bilong bal long taim bilong valv i op long valv na klosing proses. .
2. Drenej na eksos disain
Ol hul bilong drenej i gat as bilong en na ol hul bilong eksos i stap insait long bal valv straksa bilong rausim ol wara na ges ol i bin bungim long taim stret, long wanem, i gat senis long tempereja, namel kondensesen, na ol narapela samting, bilong abrusim korosen bilong ol hap insait long valv long rot bilong wara i bungim. Bal valv long stim transmisin paiplain i save lusim wara i go daun tru long rot bilong drein hul long taim bilong pasim wara i no ken bagarapim ol metal hap bilong valv na mekim valv i wok gut.
Mentenens em i bikpela samting tru
1. glasim oltaim
Lukluk long lukluk:Sekim oltaim sapos i gat ol mak bilong korosen long pes bilong bal valv, olsem ol ros spot, koting shedding, na ol narapela samting. Long ol hap i bagarap liklik ol i painim, stretim ol long taim, olsem re{1}}}aplai anti-korosen pen, na ol narapela samting. Long ol wok painimaut bilong bal long olgeta de. .
Inspeksen insait:Oltaim brukim valv bilong bal bilong sekim korosen bilong ol samting insait olsem bal, sia bilong valv, na ol sil. Long ol komponen we oli brokbrok bigwan, jenisim olgeta long taem. Long ol petrokemikel entaprais, bihainim korosivnes na frikwensi bilong yusim proses medium, wanpela strongpela intanel inspeksen saikel bilong bal valv i kamap long lukim olsem valv i wok gut. .
2. Klinim na lukautim
Wok bilong klinim medium:Mekem sua se i gat klin fasin blong konveying medium mo daonem wear mo korosen blong valv tru long ol doti long medium. Taim yu putim ol filta na ol narapela samting, rausim ol liklik pipia insait long medium na daunim bagarap bilong ol pipia long siling pes na ol intanel komponen bilong bal valv. Long indastri bilong prosesim kaikai, sapos yu filterim gut wara bilong raw materiel pastaim long yu givim em long rot bilong bal valv, dispela inap lukautim gut valv. .
Wok bilong klinim graun:Klinim oltaim pes bilong bal valv bilong rausim korosiv medium i pas long pes. Long ol bal valv ol i yusim ausait o long ol hatpela ples, ol i ken yusim ol hai-presa wara gan o ol spesel klining ejen long klinim pes bilong bal valv long holim i stap klin na daunim hevi bilong korosen. .
Lubrikesen na mentenens:Oltaim grisim stem bilong valv na ol narapela hap bilong bal valv i muv, yusim ol lubrikant i stret wantaim ol samting bilong namel na valv, we i no inap mekim valv operesen i wok gut tasol, tasol tu, pasim korosen inap long wanpela mak. Long ol indastrial paiping sistem, putim gris long stem bilong bal valv bihainim mak bilong mentenens saikel ol i makim inap skruim sevis laip bilong valv stem na mekim valv i op na pasim.
anti-}korosen pefomens garanti bilongValv bilong Bal wantaim Hand Wil em i wanpela sistemik projek, stat long gutpela seleksen bilong ol samting, aplikesen bilong ol edvans tritmen proses, i go long ol gutpela straksa disain na ol gutpela mentenens meja, wanwan link i pas gut wantaim. Tasol long rot bilong kamapim gut ol dispela anti-}korosen strateji tasol yumi ken mekim gut olsem bal valv wantaim han wil i save holim gutpela anti-korosen pefomens aninit long ol kain kain kompleks na hatpela wok kondisen, i wok gut na i ken bilip, na i go wantaim ol kain kain wara konveying sistem long indastriel prodaksen na sosel laip. Wetem kontinu advansmen blong ol materiel saens mo teknoloji blong mekem samting, oli biliv se anti-}korosen pefomens blong ol bal valv wetem ol han wil bae oli kam gud moa long fiuja, mo skop blong aplikesen bae i bigwan moa.
