Design Radius of Curvature - Horizontal Directional Drilling

Oct 14, 2019· The largest bend radius of either the drill rod or product pipe is the nuer that must be used for planning and completing the bore. A common industry standard for determining the design radius of curvature for bends used in HDD installations is to multiply the nominal diameter of the pipe in inches by 100 to determine the allowable radius in

Butt Fusion Welding of HDPE Pipes - Nexor Pipes Home

Butt Fusion is the most important and widely used method of connection for HDPE pipes larger than 110 mm. It is a method of jointing pipe ends by way of heating and cooling under pressure, resulting in pipe joints as strong as the pipe itself. The principle of butt fusion is to heat the pipe ends to a designated

HDPE PIPE DEFLECTION: THE BENDING STRESS PROBLEM

Bending Stress is directly related to pipe deflection. Every pipe size exceeds HDPE’s bending stress limits of 3,000 psi (Figure 2) at deflection levels of 5% (1/3 less than the CPPA’s suggested maximum allowable deflection of 7.5%). HDPE Pipe’s ability to support a load is typically assessed by measuring the deflection from it’s
