Mechanical machubhu anoshandiswa mumakanika uye akareruka zvimiro zvekushandisa.
Mechanical tubing inogadzirwa kuti isangane nemagumo-ekushandisa zvinodiwa, zvakatemwa, kushivirira uye makemikari zvimiro.
Piping yemakina uye akareruka zvimiro zvekushandisa.Izvi zvinobvumira kuenzana kwakanyanya kwezvivakwa mupombi yese zvichienzaniswa nemapombi akajairwa kana madhaidhi.Mechanical machubhu anogona kugadzirwa kune akajairwa zvirevo pazvinenge zvichidikanwa, asi anowanzo gadzirwa kuita "chaiyo" kuita, nekutarisa kwekutanga kusimba regoho reiyo chaiyo zviyero uye ukobvu hwemadziro.Mune mamwe maitiro akaumbwa zvakanyanya, simba regoho haringatombotaurwi, uye kugadzirwa kwema mechanical tubes "kwakakodzera kushandiswa".Mechanical piping inosanganisira yakawanda yezvimiro uye zvisiri zvemaitiro zvikumbiro.
Isu tinoshandisa simbi yedu uye hunyanzvi hwekugadzira kugadzira yakakwirira-inoshanda isina musono michina chubhu zvigadzirwa kuzadzisa zvaunoda.
Izvi zvinosanganisira kabhoni, alloys uye kunyange tsika simbi mamakisi;annealed, normalized uye tempered;kushushikana kwakasununguka uye kusagadzikana kwemahara;uye akadzikama uye akatsamwa.
Seamless simbi mapaipi emuchina uye mota, anoshandiswa mukugadzira uye kugadzirisa emota trunk uye kumashure ekisi mapombi, chaiyo midziyo, zviridzwa uye zviridzwa.
Mota furemu uye rear axle chubhu.
Kugadzira uye kugadzirisa kweiyo chaiyo midziyo, zviridzwa uye zviridzwa.
Matemu ekutumira: GBK, BKS, BK, BKW, NBK.
Tarisa uye kuyedza:Kemikari kuumbwa, michina zvivakwa, chitarisiko uye chiyero kuyedzwa, kusaparadza kuyedza, particle size yekuyedza.
Surface treatment:Oiri kunyudzwa, varnish, kupfura kudongorera.
