Investigations of sand–water induced erosive wear of AISI 304L stainless steel pipes by pilot-scale and laboratory-scale testing

Abstract

The repair costs of erosion damage caused by solid particle impingement from transporting slurries and other particle-laden liquids in pipes can be extremely high.In the absence of accurate predictive models, routine monitoring of the pipe wall thickness or the use of sacrificial coupons are required to warn of erosion damage or impending loss of containment. Apart from advantages for plant maintenance, the environmental, safety and production implications are enormous. Identification of critical pipe components susceptible to high levels of damage, and innovative ways to ameliorate the damage, has been an active topic of research for decades. Recent work at Nottingham and Southampton Universities [1] has sought definitions of flow fields and particle dispersions and their relationship to erosive wear to facilitate the development of new designs and geometries for slurry handling equipment. This paper covers research that has been aimed at determining the distribution of erosion rates and the erosion mechanisms that occur over wetted surfaces within pilotscale pipe systems handling water-sand mixtures at 10% by volume concentrations and at a mean fluid velocity of approximately 3 m/s. Experiments are presented which have been conducted on a test section consisting of an upstream straight pipe

Effect of microstructure on the erosion behavior of carbon steel

“…Erosion is very much dependent on the impacting particle properties (density, hardness, size and shape), particle feed rate, impact angle and velocity of abrasive particles and target material properties (hardness, ductility and microstructure) [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42]. In order for erosion to occur, abrasive particle must have to be harder than target material [43].…”

Mechanical and Electrochemical Synergism of API X42 Pipeline Steel During Erosion–Corrosion

“…Erosion is very much dependent on the impacting particle properties (density, hardness, size, and shape), target material, particle feed rate, temperature, impact angle, and velocity of abrasive particles [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. However, impact angle and particle velocity have been recognized as two parameters that remarkably influence erosion rates and surface degradation in tribo-systems.…”

Erosion–corrosion resistance of engineering materials in various test conditions

“…Amongst these rigs are slurry pot erosion tester [4][5][6][7][8][9], jet impingement rig [10][11][12][13][14], Coriolis erosion tester [15][16][17], pipe flow loop [18,19] and rotating cylinder apparatus [20][21][22]. Each rig has its advantages and disadvantages in terms of ease of usage, cost, ease of maintenance and control of test parameters.…”
