In addition, the "SAMM" computer program (September 1990), distributed by American Concrete Pipe Association, can also be used for this purpose. The maximum

The newcomer, which gives your concrete pipe uplift. Today, it is normal to use either roll-in type or sliding ring joints on concrete pipes. Both of them have well-known advantages as well as disadvantages. But the demands for tightness and strength of pipe systems have been increased, however. The inventor of the brilliant Lamell

FP McCann is a leading manufacturer in the supply and delivery of standard precast concrete pipes, junctions and bends to projects and merchants throughout the UK. Concrete is much more durable than any other kind of pipe. Hence, it can carry more load at any given time and gains strength over time. It cannot be weakened by heat, moisture ...

The AC pipe samples tested in the research were determined to be minimally to moderately degraded, with degradation levels measured between 1-31%. However, over 60% of the samples were determined to be below 10% degradation. All samples tested above AWWA strength requirements for crushing and hydrostatic capacity for AC pressure pipes.
