Kugadzira seamless hydraulic tubing kunowanzova nzira yekushanda, kunyanya kune zviduku zviduku.Inoda simba rakawanda uye inoda nzvimbo yakawanda.
Muma1970, musika wakachinja. Mushure mekutonga musika wesimbi wepombi kwemakore anoda kusvika 100, isina musono inotsvedza. Yakagogodzwa ne welded pombi, iyo yakawanikwa yakakodzera kune akawanda ma mechanical applications mukuvaka uye misika yemotokari. Yakatotora imwe nharaunda mune yaimbova tsvene pombi ivhu - chikamu chemafuta uye gasi.
Zvitsva zviviri zvakakonzera shanduko iyi mumusika.Chimwe chazvo chinosanganisira kuramba kuchikanda slab, izvo zvinoita kuti zvigayo zvesimbi zvinyatsogadzira-high-quality flat strip.Imwe nzira inoita kuti high frequency resistance welding ibudirire kune indasitiri yepombi.Chigumisiro ichi chigadzirwa chitsva: kushanda zvakanaka sesimbi isina musono pombi kana ichienzaniswa neinofananidzwa seamless zvigadzirwa, uye nhasi chubhu ichiri kugadzirwa yakaderera.
