I-Galvanized Pipe yinto ejwayelekile yokwakha, esetshenziswa kabanzi ekwakheni, amabhuloho, amapayipi amanzi kanye nezinye izinkambu. Kuzinhlelo zokusebenza ezisebenzayo, ukushiswa kwamapayipi agcinwe nge-galvanized kubaluleke kakhulu, ngakho-ke kuyadingeka kahle amakhono afanele ukuqinisekisa ikhwalithi nokuphepha kwe-welding. Nawa amanye amathiphu we-Welding Galvanized Pipe:
1. Ukwelashwa komhlaba kuyadingeka ngaphambi kokushiswa. Njengoba ingaphezulu lepayipi elihlanganisiwe lihlanganiswe ne-zinc under, ukwelashwa okungaphezulu kuyadingeka ngaphambi kokufaka insimbi ukususa ukungcola okufana ne-zinc under kanye namabala owoyela ebusweni. Amathuluzi anjengamasondo okugaya noma amabhulashi angasetshenziselwa ukwelashwa okungaphezulu ukuze aqinisekise ikhwalithi nokuqina kwe-weld.
2. Khetha izinto ezifanele ze-welding kanye nendlela ye-welding. Izinto zokwehlukaniswa kwezinsimbi zamapayipi we-galvanized zingaba yi-wire ye-welding noma induku ye-welding, njll., Okudingeka kukhethwe ngokwesimo sangempela nezidingo ze-welding. Ngokuya ngezindlela ze-welding, ibhukwana le-arc welding, igesi evikelekile ukufudumala nezinye izindlela zingakhethwa. Indlela ethile ye-welding edinga ukukhethwa ngokuya ngesimo sangempela nezidingo ze-welding.
3. Lawula izinga lokushisa le-welding nesikhathi. Lapho amapayipi we-welding galvaning egayiwe, kuyadingeka ukulawula izinga lokushisa le-welding nesikhathi sokugwema ukushisa ngokweqile noma ukugcwala ngokweqile kwe-welding, okuzothinta ikhwalithi ye-welding nokuphepha. Ngokuvamile, izinga lokushisa le-welding kufanele lilawulwe phakathi kuka-220 ° C no-240 ° C, nesikhathi se-welding kufanele silawulwe ngokufanele ngokwezinto zokufaka nezindlela.
4. Nakisisa ukuvikela izingxenye ze-welding. Lapho amapayipi we-welding galvaning egayiwe, ukunakekelwa kufanele kuthathwe ukuze kuvikeleke izingxenye ezinama-welded ukugwema i-oxidation ngokweqile kanye nokugqwala kwezingxenye ze-welded. Izinto ezifana ne-ejenti evikelayo noma i-tepi evikelayo zingasetshenziselwa ukuvikela ikhwalithi nokuqina kwengxenye ye-welded.
5. Yenza amasheke asezingeni kanye nokuhlolwa. Ngemuva kokuthi i-welding isiqediwe, ukuhlolwa kwekhwalithi nokuhlolwa kuyadingeka ukuze kuqinisekiswe ikhwalithi nokuphepha kwe-welding. Izindlela zokuhlola ezinjenge-ultrasonic, ray noma i-magnetic parte zingasetshenziselwa ukuhlolwa kwekhwalithi ye-welding ukuze uqinisekise ukuthi ikhwalithi ye-welding ihlangabezana nezidingo.
