                                        氣瓶水壓外測法的優缺點對比

                                        2012-09-06 0

                                        前面和大家一起學習了氣瓶水壓試驗內測法的優缺點,今天小編就來帶大家簡單了解一下氣瓶水壓外測法的優點和缺點,希望對大家有幫助。

                                        氣瓶水壓外測法的優點

                                        氣瓶水壓外測法試驗時,全變形值可以直接通過量筒讀出,不需要通過復雜的計算,不需要測定管道的B值,同樣不受溫度對水的平均壓縮系數的影響。同時試壓管道中與氣瓶內的氣體對測量結果幾乎沒有影響。

                                        氣瓶水壓外測法的缺點

                                        不能反映水壓時瓶體的泄漏、明顯變形、異常聲響等缺陷;

                                        由于水套、水套與氣瓶、氣瓶與接頭之間存在較多死角,無法排空;操作復雜,設備價值較高,不利于批量生產;

                                        受限制的因素太多,阻礙了氣瓶及壓力容器行業的正常發展。

                                        以上就是氣瓶水壓外測法的優缺點,學習完了氣瓶水壓內測法及外測法的優缺點之后,相信大家對如何選擇合適的氣瓶水壓試驗機已經有了清晰的認識。
