Polyethylene Pipe (Gas) User Guide
Study time: 2 hours
The Pipeline Toolbox is home to many tools and calculators. The PLTB User’s Guide presents information, guidelines and procedures for use during design, construction, operations and integrity tasks for field or office applications. When selecting pipe materials, designers, owners and contractors specify materials that provide reliable, long-term service durability, and cost-effectiveness. Solid wall PE pipes provide a cost-effective solution for a wide range of piping applications. PE pipe is also effective for above ground, buried, trenchless, floating and marine installations. Wheel load from trucks or other vehicles are significant for pipe buried at shallow depths. The resultant load transferred to the pipe depends on e vehicle weight, the tire pressure and size, vehicle speed, surface smoothness, pavement and distance from the pipe to the point of loading. Surcharge loads, such as footings, foundations or other stationary loads, create pressure in the soil beneath the loaded area. This pressure will be distributed through the soil such that there is a reduction in soil pressure acting on the pipe with an increase in depth or horizontal distance from the surcharge area.
