DN1200 GRP Test Spool

FEA Analysis for a DN1200 GRP Test Spool

In this case study, a burst test was conducted to demonstrate the strength of a DN1200 Glass Fiber Reinforced Plastic (GRP) pipe. The objective was to ensure that the pipe spool could endure an internal pressure six times greater than the design pressure of 10 Barg, equivalent to 60 Barg for a short duration.

Stress Analysis of a GRE Firewater Piping System

This case study describes the stress analysis performed on a firewater piping system located in the Middle East. The system was constructed using Glassfier Reinforced Epoxy (GRE) pipes. Most of the piping was buried underground and included several connections to above-ground steel piping, fire hydrants, and similar equipment.

Strength Assessment of a GRE Dump Caisson

At an oil refinery plant in Saudi Arabia, a fiberglass-reinforced plastic (FRP) pipe fire water system has been installed, predominantly buried underground. Since its installation, the system has experienced several failures. DRG was tasked with conducting a comprehensive pipe stress analysis to assess the system’s integrity.

Strength Assessment of a GRE Dump Caisson

A large-diameter seawater dump caisson, constructed from Glass Reinforced Epoxy (GRE), required a comprehensive strength assessment. This caisson featured five nozzles, with one positioned in the blind flange at its top, all subject to external piping loads. The primary objective was to determine the necessary reinforcement for the intersection of the caisson and the nozzles.

GRP Vessel Sizing: Determination of Wall Thickness According to ASME RTP-1

This case study details the determination of wall thickness for a Glass Reinforced Epoxy (GRE) tank.

The process of defining the wall thickness was conducted in two steps. The initial step involved sizing according to the design rules specified by RTP-1 Subpart 3A “design by rules.” The subsequent step verified deviations from this code using a series of finite element analyses.

Fiberglass Transportation Line Stress Analysis

A 5-inch glass-reinforced epoxy (GRE) transportation line has been installed underground, featuring several above-ground steel pipe connections. Designed to withstand a pressure of 150 bar and tested up to 214 bar, the line operates under a steady temperature of 40°C, minimizing thermal impacts. Issues with original pipe elbows prompted the installation of custom-made large radius bends using 22.5-degree elbows. Notably, hydrotest conditions were carefully considered during this process.
