style="text-indent:25px">對于球墨鑄鐵給水管來說，其主要的標準主要出自國家規(guī)范，規(guī)范中也明確表明只有先試壓合格才能進行回填，其中，這些試壓標準包括了：管道水壓試驗的分段長度不能大于一千米，其次，試驗的管道應該在滿水并且無壓力的情況下充分浸泡，廈門新興球墨鑄鐵管購買，廈門新興球墨鑄鐵管購買，而球墨鑄鐵給水管的無砂漿內(nèi)襯的浸泡時間不能低于24小時，如果有砂漿的內(nèi)襯，時間更是需要延長到48小時以上。當然了，以上說的所有水壓試驗都應該在回填之前進行，只有試壓合格之后才允許回填，廈門新興球墨鑄鐵管購買，而回填之前還要檢查管道接口和管身是否沒有破損以及滲漏，在這樣的前提下才為合格哦。離心球墨鑄鐵管有什么特性？廈門新興球墨鑄鐵管購買</p><div
