This article is to introduce the new designed plastic-steel-fiberglass composite pressure pipe (GSP pipe) for long distance water transportation, with max diameter 5000mm. This multimaterial composite pipe combines the steel hardness, PE anti-rust and fiberglass strength makes it long lifetime, higher pressure and material saving.
The GSP is processed by three layers whose inner layer is PE, middle layer is spiral welded steel, outer layer is winded fiber glass reinforcement, with 1.6Mpa pressure. The pipe is produced by roll plastic and winding.
The steel layer strength is 200 times as PE pipe, enhanced the pipe pressure and decreased the pipe wall thickness; PE inner layer makes the rust free, and lower water friction rate; outer layer fiberglass layer protect the steel pipe from rust and increases the ring stiffness. The pipe is produced with bell and spigot which makes the installation easier, faster and lower cost. All of the features of the new composite big diameter pipe make it a potential replacement pipe on long distance water transportation to solve the problems of fragile cements pipe and easy rust steel pipe.

PP-R (random copolymerized polypropylene) has been widely used in hot and cold water systems. However, the standard PP-R pipes have the disadvantages of a large high-temperature thermal expansion coefficient, an insufficient notched impact strength, and a low temperature and pressure resistance. In this paper, a new...

In the rural commune of Ait Bayoud, Morocco, two of the most remote villages in the area, Ilguiloda and Izgouaren, live with water scarcity. To meet their water needs, women and children walk several kilometers to the nearest spring each day, often multiple times a day. Consequently, children cannot attend school...

HDPE pipe can be relatively easily scratched during the manipulation on the site, which is especially true for the marine pipelines. Installing the scratched marine pipe with the S bend method presents a risk and repair methods are usually performed. Currently, there is no standard defining the repair procedure, in...

For PE 100-RC, two tests are still under development for pipes: the point load test (PLT) and the accelerated notch pipe test (aNPT). The PLT was developed by a project group consisting of manufacturers and end users. The PLT determines the resistance to point loads as they can occur in practice. An earlier study...

The Point Load Test (PLT) [ 1, 2] was designed to simulate the SCG (slow crack growth) failure initiated by a rock pressing into the exterior wall of a polymer pipe. Today’s PE materials sustain long PLT testing times, due to its high SCG resistance design. Consequently, an accelerated “PLT+” with the support...

Flowable fill is used for many applications, but mainly for pipe trench embedment and backfill. There are three ways that using flowable fill can be kind to the environment. Because flowable fill is self-leveling and has a strength greater than the native soil, the trench cross section can be minimized. This means...
