HDPE Pipe’s ability to support a load is typically assessed by measuring the deflection from it’s original shape (Figure 1). This measurement is relatively simple, both in the laboratory and the field, and allows a measurable quantity to be compared a way to Puhui Pipe manufacturer in China
HDPE pipe and fittings are available in various lengths, in diameters of 3 inches (7.62 cm) to 63 inches (160.02 cm). Thermal butt fusion joints provide an economical and fast method of delivering a complete, long, continuous length of pipe, often eliminating the need for elbows in larger radius appliions.

For rigid pipe such as concrete pipe and AC pipe, the pipe will break if unsupported since the pipe cannot flex in response to loads. Depending on the appliion and pipe strength, various degrees or classes of bedding with a load factor of 2.2 can provide twice as much load carrying ability as Class D bedding with its load factor of 1.1 (i.e. 2.2 = 1.1 X 2).
The bedding factor is defined as the ratio of the supporting strength of pipe under the field loading condition (W) to the supporting strength of similar pipe in a TEB test. Because cracking in concrete is a function of tensile stresses in the pipe wall, it can be shown ( Spangler 1933 ; ACPA 1991 ) that the bedding factor can also be expressed as a ratio of moments in the TEB test and field Puhui Pipe manufacturer in China
