What items need to be tested for corrugated pipe testing? And what are the sampling methods? The engineer from Baijian Testing introduced that the corrugated pipe has excellent ring flexibility and impact resistance, so it has many uses, mainly concentrated in municipal drainage, sewage pipeline system engineering, underground drainage and drainage in apartments and residential areas, pre buried pipelines on highways, underground seepage pipe networks in golf courses, irrigation and drainage projects in farmland, as well as fluid transportation and ventilation in chemical and mining industries Protective sleeves for underground pipelines and communication cables. So, what items need to be tested for corrugated pipe testing? And what are the sampling methods? Below is a detailed introduction by the Baijian engineer The classification of corrugated pipes mainly includes: metal corrugated pipes, corrugated expansion joints, and corrugated heat exchange pipes
Routine testing items for corrugated pipes: size, density, ring stiffness, ring stiffness, impact performance, ring flexibility, oven test
Sampling method for corrugated pipe testing: metal corrugated pipes: select three typical specifications of products from the same number of corrugated pipes, the same cross-sectional shape of corrugated pipes, and the same stiffness characteristic corrugated pipes for inspection and testing.
Plastic corrugated pipes: The products are inspected and accepted by the approval unit. A certain amount of products produced stably and continuously with the same formula, production process, and equipment are the same batch, and the quantity of each batch does not exceed 10000m.
