Ngenxa yokuthi ipayipi lensimbi engagqwali elingu-316L eliwugqinsi liyamelana nokugqwala, alikwazi ukumelana nokushisa, livame ukusetshenziswa kwezokwelapha, imboni yamakhemikhali, ukudla, imboni yokukhanya, imishini yamakhemikhali, amapayipi ezimboni kanye nezingxenye zemishini. Yiqiniso, amapayipi ensimbi anezindonga eziwugqinsi nawo afaneleka ukukhiqizwa nokukhiqizwa kwamapayipi okukhipha umoya kanye namapayipi ayisisekelo ahlukahlukene. Nokho, amapayipi ensimbi anezindonga eziwugqinsi agqwala ngemva kwesikhathi esithile esetshenziswa. Ngakho-ke, yini okufanele ngiyenze uma amapayipi ensimbi engagqwali angu-316L awugqinsi egqwalile?

Siyazi ukuthi uma amapayipi ensimbi engagqwali angu-316L awugqinsi egqwala ama-thermocouples, i-anodic oxidation iyabhujiswa futhi i-electrode engeyinhle iyagcinwa. Uma sizama ukugcina ipayipi lensimbi eliwugqinsi elinezindonga njenge-electrode eyinegethivu kusukela ekuqaleni kuya ekugcineni, ipayipi lensimbi ngeke ligle kalula. Le ndlela ye-anti-corrosion ibizwa ngokuthi i-pipeline cathodic protection. Lena futhi indlela yokuphelezela. Ayisebenzisi nje kuphela izinto zensimbi ezihambayo njengamafilimu okuvikela kodwa futhi ibhubhisa izinto zensimbi ezihambayo futhi igcina izingxenye zensimbi. Olunye ucwaningo lwesayensi lungenziwa ngaphandle kokucekela phansi i-anodic oxidation. Ngakho-ke, indlela yokuvikela i-cathodic ingahlukaniswa ngendlela yefilimu yokuzivikela kanye nendlela yokuvikela imishini kagesi.

Nge-alloy esebenzayo njengefilimu evikelayo, yifake ebusweni bepayipi yensimbi engagqwali engu-316l evikelayo, noma uxhume insimbi evikelayo ngocingo, ukuze ifilimu evikelayo kanye nensimbi yokuvikela kube izinhlangothi ezimbili zokusabela kweseli ye-galvanic. Njengoba ifilimu evikelayo iyinsimbi esebenzayo, inomphumela we-anodic oxidation ebhethri, i-oxidized futhi yonakaliswa umoya obolayo, futhi i-alloy evikelayo i-cathode. Ibhethri elincane lasekuqaleni liyama noma libe buthaka emsebenzini we-cathode, bese livikela izingxenye zensimbi. Lapho ifilimu yokuzivikela isizogqwala, ingashintshwa enye ifilimu yokuzivikela.

Ngakho-ke, le ndlela ye-anti-corrosion iyindlela yokuvikela imoto elahlekile, eyaziwa nangokuthi indlela yokuvikela i-cathodic. Isibonelo, kunamabhulokhi e-zinc kuma-boilers we-gas steam, futhi i-zinc ivame ukushumeka eduze kophephela bemikhumbi. I-Zinc isebenza kakhulu kune-iron, ngakho i-zinc igqwala kancane futhi ivikela isithando somlilo nophephela. Phakathi nenqubo ye-electrolysis, i-electrode exhunywe esigxotsheni esingesihle sokuhlinzekwa kwamandla akulula ukulinyazwa. Kule electrode, i-electron ayidingekile, ngakho-ke udonga olunegethivu engu-316L odongeni oluwugqinsi lwepayipi yensimbi engenasici ngokwalo alukwazi ukulahlekelwa ama-electron futhi lube ama-ion amahle.

Ngamanye amazwi, i-electrode engalungile akulula ukuyilimaza. Ngokwalesi simiso esiyisisekelo, singasebenzisa isimanje sangaphandle ukuxhuma ipayipi lensimbi engagqwali enodonga oluwugqinsi ngoxhumo olungalungile lokuphakela kwamandla okushintsha njengoxhumano olungeluhle, setha ugesi osizayo kanye nesigxobo esihle sokuphakelwa kwamandla okushintshayo njenge uxhumano lwe-anodic oxidation, bese ugcina imishini engalungile. I-anodizing kungaba amapayipi amanzi angcolile, amathrekhi esitimela amadala, njll., agqwala kancane ngaphansi kwezimo eziphansi. Le ndlela ifana nendlela yefilimu yokuzivikela.
