The specification, design and construction of drainage

2018-10-5  Minimum crushing strength values for pipes or pipe sections are specified in two ways (BS EN 295-1 2.9). For 100 and 150 mm diameter pipes specific values are given of 22, 28, 34 and 40 kN/m, with higher strengths permitted in steps of 6 kN/m. For larger pipes, crushing strengths are given according to class numbers, as shown in table 4 below for UK pipe sizes.

How Strong is PVC Pipe? (With PVC Strength Charts)

2016-8-10  The above is a question very commonly asked. While it may seem like a simple question, how to define the strength of PVC pipe is far from straightforward. The term "strength" can mean a number of things, all of which cannot be covered in one blog post. The three types of strength measurements I will go into in this post are collapse pressure, burst pressure, and tensile strength.
