“…Following the current global trend, GRP stand as a suitable and most effective replacement for the ductile iron pipes and PVC pipes based on it material properties especially on the corrosion and erosion resistance [6]. although considerable work has been done on the dynamic stability of pipes and its related researches; but that relating to the GRP has not been completely explored [6,16,[21][22][23][24][25][26][27][28][29][30]. Nimish et al [5] studied the stress analysis of Glass Reinforced Polymer (GRP) pipes.…”

“…Regression analysis were conducted to determine the long-term deflection of the GFRP pipe after 50 years of construction. Ana et al [28] presented experimental results conducted on three samples of a PN SN10000 DN150 PN10 pipe buried in three different types of terrain: neutral, acidic, basic. They were subjected to axial load, measuring the force applied deformation force function.…”

In the past, almost every industry worldwide patronizediron and its alloys for every major industrial design, construction and other forms of work. However, with the advent of the Glass Reinforced Plastic (GRP)as accepted in the United Kingdom or the Fibre Reinforced Plastic as accepted in the United States, which was discovered in the nineteen thirty’s (1930’s), the Glass Reinforced Plastic (GRP) has become very versatile as it has become a household name in most industries globally .It has attained this height through the significant properties it possesses, which include its ability to transform into moulds of difficult and delicate shapes and sizes which iron and its alloy may not find easy to submit to. It brings a host of otherbenefits in the form of long term performance and reliability, ease of installation and the ability to withstand corrosion and tuberculation. A service life of more than thrice that of the ductile iron pipes to mention but a few. Ductile Iron pipes are used in most petrochemical industries where pipeline plays a very important role in transporting crude oil and gas. As the service duration increases, the pipe lines are affected by corrosion mechanism which can lead to fatal accident. Corrosion can occur atboth the internal and external surface of the pipelines. In general, corrosion would cause metal loss which leads to reduction in pipeline thickness and consequently reduce its strength. Itbecomes necessary that the stability of the Glass Reinforced Plastic (GRP) pipes are carefully investigated especially in the event of high pressure turbulent flows. This is the thrust of this work. In the light of the above, ductileiron pipes and Glass Reinforced Plastics (GRP) pipes of the same thicknesses were investigated, some special characteristics such as the bursting pressures were calculated using Peter Barlow’s formula. The ANSYS software was also used for modelanalysisand compare the stress profile under dynamic condition for both pipes. Also the cost of production of pipes, classification and the difficulties encountered during their installation processes wereexamined. The result indicated an overwhelming encouragement to use Glass Reinforced Plastic (GRP) pipes as substitutes to the traditional ductile iron and its alloys in view of the fact that Glass Reinforced Plastic (GRP) pipes withstand corrosion and tuberculation while saving the huge cost that would have been used forpigging
