不銹(xiu)鋼光(guang)亮(liang)(liang)(liang)盤管(guan):由不銹(xiu)鋼帶焊接好再減壁,減壁由厚到(dao)薄,此過(guo)程可(ke)以使(shi)壁厚均勻,光(guang)滑,并且減壁拉(la)伸(shen)管(guan)壁形(xing)(xing)成(cheng)了無焊縫的效果(guo).按照肉眼看(kan)是(shi)(shi)(shi)無縫管(guan),但是(shi)(shi)(shi)其(qi)工藝決定(ding)(ding)(ding)是(shi)(shi)(shi)焊管(guan).減壁的過(guo)程中伴隨光(guang)亮(liang)(liang)(liang)退(tui)火,使(shi)內外(wai)壁不會形(xing)(xing)成(cheng)氧化層,內外(wai)光(guang)亮(liang)(liang)(liang),美(mei)觀,這真是(shi)(shi)(shi)醫(yi)用產品所需要的。下道工序(xu)需要定(ding)(ding)(ding)徑(jing),即大拉(la)小工藝,確定(ding)(ding)(ding)外(wai)徑(jing),外(wai)徑(jing)公(gong)差一般可(ke)以達到(dao)正(zheng)負0.01mm.
