Imvamisa izinto zensimbi ezingagqwali yizinto eziphambili ze-flange, kuyindawo ethinteka kakhulu yikhwalithi yenkinga. Lesi futhi isihloko esibaluleke kakhulu kwikhwalithi yabakhiqizi bensimbi engenasici. Ngakho-ke ungazihlanza kanjani amabala asele ku-flange kahle futhi ngokushesha?

I-Flange esetshenziswa kakhulu iyinsimbi engama-304 engagqwali. Ama-Flanges enziwe ngale ndaba azothuthukiswa ngo-20 ℃ naku-10% nitric acid ngesilinganiso esingaphansi kuka-0,1 mm ngonyaka; Ku-10% ebilayo acetic acid, isilinganiso sokukhulisa singaphansi kwe-0,1 mm ngonyaka; Izinga lokugqwala elingaphansi kuka-0,1 mm ngonyaka ngo-50% ama-citric acid; I-20% ye-potassium hydroxide ihlanganiswe ngesilinganiso esingaphansi kuka-0,1 mm ngonyaka. Ku-60 ℃, izinga lokukhulisa le-80% ye-phosphoric acid isengaphansi kuka-0,1 mm ngonyaka. Kepha ku-50 ℃, izinga lokukhulisa le-2% sulfuric acid ngu-0.016 mm ngonyaka. Ngakho-ke, i-tube yensimbi engenasici ibekwe yi-Cold Rolled strip ye-Stainless Stinanless Stinance ifakwe ukugcwaliswa kwamapayipi wensimbi engagqwali kanye ne-yixing iron engenasisekelo yensimbi engase isetshenziselwe ukuhambisa i-acid acid noma i-alkaline chemid. Ama-flangeni ensimbi engenasici ajwayele ukwenziwa emkhakheni wothuli, ozohlala ewa ebusweni bemishini. Lokhu kungasuswa ngezixazululo zamanzi noma ze-alkaline. Kepha ukunamathela kokungcola kudinga ukusebenzisa amanzi aphezulu okucindezela noma umusi ukuze uhlanzeke. Bese kuba khona impikiswano ye-Iron Flow Powder noma i-Iron eshumekiwe. Kunoma ikuphi komhlaba, i-iron yamahhala izogqwala futhi i-corrode amafulethi ensimbi engagqwali. Ngakho-ke kufanele kusulwe. I-Flow powder ngokuvamile ingasuswa kanye nothuli. Ukunamathela okuqinile futhi kufanele kuphathwe ngensimbi eshumekiwe.

Lokhu okungenhla kuyindlela yokuhlanza yamabala asele ensimbi engenasici, insimbi engenacala ayintekenteke, kepha futhi kudingeka ihlanzwe kahle futhi igcinwe kahle.
