Ductile iron pipe hydrostatic testing is a complex task, requiring attention to detail to ensure safety. How much pressure in kilograms is typically applied during ductile iron pipe hydrostatic testing? Let's take a look together now.
One, ball and ductile iron pipe pressure test several kilograms
Pressure testing must not exceed 16 kg, and the specific decision should be based on actual conditions. Additionally, the minimum tensile strength achievable with ductile iron pipes is 420 MPa, the minimum yield strength is 300 MPa, and the minimum elongation is 7%.
What are the construction considerations for ductile iron pipes?
1. When installing ductile iron pipes, it's necessary to apply lubricant to both the outer surface of the pipe's socket and the inner wall of the gasket. It's crucial to ensure even application for a tighter bond. Moreover, wait until the pipe is securely bonded before releasing your hand to guarantee its stability.
2. When lowering the pipe, it must be placed to the bottom of the groove according to relevant requirements. Common methods include manual and mechanical approaches, with the choice depending on the specific situation. Moreover, the surface dirt on the pipeline must be thoroughly cleaned during installation.
3. When installing machinery, it must be handled properly, with no details overlooked, and care must be taken to avoid re-contaminating already cleaned pipes, which could affect their use. Additionally, during the cleaning of pipe openings, all debris inside must be removed to ensure safety.
4. If there's any substance stuck on the gasket, it must be cleaned thoroughly. Then, shape the gasket to resemble the socket groove and press it in. During this process, ensure that it doesn't lift or deform to avoid unnecessary complications with the overall effect.
