Seamless Elbow Manufacturing process (Kupeta Kupisa & Kutonhora Kubhenda)

Imwe yedzakajairika nzira dzekugadzira magokora kushandisa inopisa mandrel kukotama kubva kune yakatwasuka simbi pombi.Mushure mekupisa pombi yesimbi pakupisa kwakakwirira, pombi inosundirwa, yakawedzerwa, yakakotamiswa nemidziyo yemukati ye mandrel nhanho nhanho.Kuisa inopisa mandrel bending kunogona kugadzira yakakura saizi renji isina musono gokora.Hunhu hwemandrel kukotama hunoenderana zvakanyanya neiyo yakabatanidzwa chimiro uye zviyero zve mandrel.Iko kushandisa zvakanakira kupisa kwekupeta magokora kunosanganisira kutsauka kweukobvu kudiki uye yakasimba kubhenda radius pane imwe bending methond mhando.Zvichakadaro, kushandisa kupeta panzvimbo pemabhenji ekare kunoderedza huwandu hwemawelds anodiwa.Izvi zvinoderedza kuwanda kwebasa rinodiwa uye zvinowedzera kunaka uye kushandiswa kwepombi.Nekudaro, kukotama kunotonhora maitiro ekukotamisa pombi yesimbi yakatwasuka patembiricha yakajairwa mumuchina wekupeta.Cold bending inokodzera mapaipi ane kunze dhayamita 17.0 kusvika 219.1 mm, uye madziro ukobvu 2.0 kusvika 28.0 mm.Iyo yakakurudzirwa kubhenda radius ndeye 2.5 x Ita.Kazhinji pakukotama radius ye40D.Nekushandisa kukotama kunotonhora, tinogona kuwana magokora madiki eradius, asi isu tinofanirwa kurongedza zvemukati nejecha kudzivirira kuunyana.Kukotama kunotonhora inzira inokurumidza uye isingadhure yekukotama.Iyo inokwikwidza sarudzo yekugadzira mapaipi uye zvikamu zvemuchina.

Welded Elbow Manufacturing process (Idiki & Hombe)

Welded elbows anogadzirwa kubva kumarata esimbi, saka haisi seamless simbi magokora.Shandisa mold uye wodzvanya ndiro yesimbi kune chimiro chegokora, wobva waisa musono kuti ive simbi yekupedzisa gokora.Ndiyo nzira yekare yekugadzira yemagokora.Makore achangopfuura masaizi madiki magokora anenge akagadzirwa kubva papombi dzesimbi izvozvi.Pamagokora mahombe, semuenzaniso, zvakaoma kugadzira magokora anopfuura 36” OD kubva papombi dzesimbi.Saka inowanzogadzirwa kubva kumarata esimbi, kudzvanya ndiro kusvika pachimiro chehafu yegokora, uye kubatanidza mahafu maviri pamwechete.Sezvo magokora akaiswa mukati memuviri wayo, kuongororwa kwejoinhi rewelding kunodiwa.Kazhinji isu tinoshandisa iyo X-Ray yekuongorora seNDT.
