                                        關于管道水壓試驗機的試驗壓力及試驗標準

                                        2016-10-18 0

                                        管道用水壓試驗機的試驗壓力一般為管道工作壓力的1.5倍左右,不同用途的管道水壓試驗壓力和標準各有不同,小編總結了以下的管道水壓試驗標準,供大家參考:

                                        1、生活飲用水和生產、消防合用的管道,試驗壓力為工作壓力的1.5倍,但不得大于1Mpa,在10min內壓力降不大于0.05Mpa,然后將試驗壓力降至工作壓力進行外觀檢查,以不滲漏為合格;

                                        2、自來水管道試驗壓力一般為1Mpa;

                                        3、給水鑄鐵管道:當工作壓力≥0.5Mpa時,試驗壓力=工作壓力+0.5Mpa;當工作壓力≤0.5Mpa時,試驗壓力=工作壓力×2;10min內壓力降不大于0.05Mpa為合格;

                                        4、鋼管試壓標準為工作壓力+0.05MPa;

                                        5、非金屬管材的試驗壓力:當工作壓力<0.6Mpa時,為工作壓力的1.5倍;當工作壓力≥0.6Mpa時,為工作壓力+0.3Mpa;

                                        6、綜合試壓:冷熱水管道,以不小于0.5Mpa,不大于1Mpa的壓力試驗一小時壓力降不超過0.05Mpa,不滲漏為合格。

                                        我司多年來專注研發生產水壓試驗機,適用于管道、閥門、壓力容器等產品的水壓試壓、耐壓、密封性能檢測、靜壓爆破等性能的測試。
