Ipayipi lensimbi eliphehliwe lishibhile futhi ukusebenza kwe-anticorrosive kuhlobene kangcono namapayipi ensimbi engagqwali. Ipayipi elinothayela ekuklanyweni nasekukhiqizeni uhlobo olubalulekile lokusebenzisa ngokugcwele umklamo ojwayelekile, ipayipi lensimbi elithambile elithambile ngokuvamile lihlanganisa amapayipi, ikakhulukazi amapayipi amanzi asekhaya aphansi, izindleko eziphansi, ukumelana nokugqwala okuhle, ukuxhumana kwenziwa kusetshenziswa i-British Elbow, tee, iDemo. izingxenye zokufeza, futhi ngokuvamile azinayo indlela yokuxhuma i-welding, i-welding izobhubhisa i-zinc enamathela, i-welding slag ijwayele ukuhlanganisa, i-porosity phenomenon kanye nomthelela we-anti-corrosion effect.

Ipayipi lensimbi eliphekwe ngensimbi elithambile ukusebenzisa isimiso sokugqwala kwe-electrochemical, ukuvikelwa kwe-cathodic futhi lisetshenziswe ikakhulukazi ekuthinteni kwensimbi ne-zinc anode, i-carbon steel a cathode, i-zinc njenge-anode, ngaleyo ndlela kuqinisekiswe ukuthi insimbi ingagqwali.Ngokuvamile okusetshenziselwa ukucubungula izinsimbi noma ukucutshungulwa kwamapayipi amanzi kuwuxhumano oluluchungechunge lwendawo yamapayipi okushisa okuphansi enengcindezi eningi ngaphandle kwengozi.Amapayipi ensimbi athambile ngokuvamile angemva kokwelashwa okungaphezulu endaweni yawo embozwe ungqimba lwefilimu elivikelayo, elinediphu elishisayo nelifakwe kubanda ukuvimbela ukugqwala.

Ipayipi lensimbi eliphehliwe ngenxa yamandla aphezulu kune-iron, ukugqwala kwe-zinc kuqala, ngakho-ke lalivikela ipayipi lensimbi, futhi uma lingaxhunywanga, ungasebenzisa izindlela zokushisela, ukungena komoya wegumbi lokushisela kufanele kube kuhle, ngoba i-zinc oxide inobuthi kubantu. i-asidi electrode J422 ingafakwa ezishiselwe.
