不銹鋼光(guang)亮盤管(guan)(guan):由(you)不銹鋼帶焊接好再(zai)減(jian)(jian)壁(bi),減(jian)(jian)壁(bi)由(you)厚到薄,此過程(cheng)可(ke)以使(shi)壁(bi)厚均勻,光(guang)滑,并且減(jian)(jian)壁(bi)拉伸管(guan)(guan)壁(bi)形成了(le)無(wu)焊縫的效果.按照肉眼看是(shi)無(wu)縫管(guan)(guan),但是(shi)其(qi)工藝決定(ding)是(shi)焊管(guan)(guan).減(jian)(jian)壁(bi)的過程(cheng)中(zhong)伴隨光(guang)亮退火,使(shi)內外壁(bi)不會形成氧(yang)化層,內外光(guang)亮,美觀(guan),這真是(shi)醫用(yong)產品所需要的。下道工序(xu)需要定(ding)徑(jing)(jing),即大拉小工藝,確定(ding)外徑(jing)(jing),外徑(jing)(jing)公(gong)差一般可(ke)以達到正負(fu)0.01mm.
