與工作狀態(tài)下的壓力、溫度、流量有關。較高允許流速是指管系較低工作壓力、較高工作溫度時的實際流速。氧氣管道的直徑的確定, 要在高峰負荷情況下滿足安全流速 (較高允許流速)的要求, 并且需要留有余地, 這是為了確保安全。液氧管道一般采用不銹鋼管道或銅及銅合金管道, 由于液氧管道為低溫狀態(tài), 所以對于液氧流速沒有嚴格限制。壓力管道長徑比很大，極易失穩(wěn)，受力情況比壓力容器更復雜。東莞特氣空氣壓縮機管道施工</p><p style="text-indent:25px">嚴禁用氧氣吹刷管道或用氧氣試漏、試壓。東莞工藝壓力管道設計施工</p><p

BA管常使用于和芯片接觸但不參與過程反應的氣體。管內表面粗糙度是衡量管材質量的標準。粗糙度越低，其顆粒攜帶可能性較大降低。東莞工藝壓力管道設計施工</p><p
