Pvc pipe penetration test

Player
Short video description
What may be a cost-effective solution is not always what it seems. I was involved in the plumbing design for an eight-story residential assisted living facility in Cambridge, Mass. The architect had convinced himself that PVC piping, on a cost-per-linear foot basis, was so much cheaper than cast iron and copper that it was ludicrous to consider cast iron as a material of construction for his project. He was quite justified in his thinking, given that lengths of PVC Schedule 40 piping are about one-fourth the cost of hubless cast iron.

Assessment of the Strength and Toughness of Modified PVC Pipes

ASTM's plastic pipe standards are instrumental in specifying, testing, and evaluating the physical, mechanical, design, and installation requirements for plastic, polymeric, or elastomeric pipes, tubing, and fittings, including the seals, threads, and couplings that join them together. Such products are intended for use in high pressure storage vessels, water distribution systems, waste drainage and sewerage systems, agricultural drainage and septic tank leach fields, and existing sewer and conduit rehabilitation. These plastic pipe standards help product manufacturers, industrial processing plants, plumbing companies, and other users and producers of these products to ensure proper and safe fabrication, assessment, installation, and utilization.

For rubber ring joints to resist plant root penetration, it has been reported and promulgated into Australian Standards that a sufficiently high contact pressure between the rubber and the pipe must be maintained. The evaluation of the appropriate interfacial pressure to be used has been under discussion for some time and different values have been used in different standards. This matter has been the subject of considerable controversy, and decisions on the interface pressure used will affect the performance and ease of insertion of a rubber ring joint.
