Ngokuvamile impahla yensimbi engagqwali iyona nto eyinhloko ye-flange, indawo ethinteka kakhulu yikhwalithi yenkinga. Lesi futhi isihloko esibaluleke kakhulu kukhwalithi yabakhiqizi be-stainless steel flange. Ngakho-ke ungawahlanza kanjani amabala asele ku-flange ngendlela efanele futhi ngokushesha?

I-flange esetshenziswa kakhulu yi-304 insimbi engagqwali. Ama-flange enziwe ngale nto azogqwala ku-20℃ futhi ku-10% ye-nitric acid ngenani elingaphansi kuka-0.1 mm ngonyaka; Ku-10% abilayo i-acetic acid, izinga lokugqwala lingaphansi kuka-0.1 mm ngonyaka; Izinga lokugqwala elingaphansi kuka-0.1 mm ngonyaka ku-50% citric acid; U-20% we-potassium hydroxide ugqwalile ngenani elingaphansi kuka-0.1 mm ngonyaka. Ku-60℃, izinga lokugqwala lika-80% i-phosphoric acid lisengaphansi kuka-0.1 mm ngonyaka. Kodwa ku-50℃, izinga lokugqwala lika-2% sulfuric acid liyi-0.016 mm ngonyaka. Ngakho-ke, ishubhu lensimbi engagqwali elizungezwe umugqa obandayo ogoqiwe wensimbi engagqwali oshiselwe ngensimbi engagqwali ofakwe amapayipi ashiselwe kanye ne-Yixing insimbi engagqwali flange ingasetshenziswa ukuthutha i-asidi ebuthakathaka noma uketshezi lwamakhemikhali ane-alkali olubuthakathaka. Ama-flange ensimbi angenasici avame ukwenziwa emkhakheni wothuli, okuzohlala kuwela phezu kwemishini. Lezi zingasuswa ngamanzi noma izixazululo ze-alkaline. Kodwa ukuze adhesion of ukungcola kudingeka usebenzise amanzi anomfutho ophezulu noma umusi ukuhlanza. Bese kuba nendaba ye- iron float powder noma insimbi eshumekiwe. Kunoma iyiphi indawo, insimbi yamahhala izogqwala futhi idle ama-flange ensimbi engagqwali. Ngakho kufanele kusulwe. Impushana entantayo ngokuvamile ingasuswa kanye nothuli. Ukunamathela okuqinile futhi kufanele kuphathwe ngensimbi eshunyekiwe.

Okungenhla kuyindlela yokuhlanza yamabala asele ku-flange yensimbi engagqwali, insimbi engagqwali ibuthakathaka, kodwa futhi idinga ukuhlanzwa kahle nokugcinwa.
