Gas explosion model for grey cast iron pipes in Amsterdam
نویسندگان
چکیده
This thesis concerns grey cast iron gas pipelines in Amsterdam managed by the regional gas and electricity grid operator Liander. Due to brittle nature and aging process of grey cast iron, probability of explosion in this type of pipelines seems to be increasing. A model for the gas explosion probability is proposed. Multiple factors are taken into consideration, including pipe’s age, length, wall thickens and environmental characteristics (e.g. pH, distance to nearby property) The model is a tool which provides assessment of the probability of explosion in grey cast iron pipes in Amsterdam. It also counts the contribution of each type of leakage to overall explosion probability. The model works for different pipes subpopulations (e.g. with respect to post code area, type of pressure, age). Numbers presented in this thesis, coming from real databases, have been altered due to confidentiality reasons.

Gray cast-iron water pipe metallurgy
The results of a metallographic study of grey cast iron water pipes are reported. These pipes had been installed between 1885 and 1973 in eight different water systems. Each pipe had been extracted during scheduled maintenance or failure repairs to provide data for a larger study to produce a methodology for determining the residual life of grey cast iron pipes. This metallographic study was co...

Pulsed Eddy Current (PEC) sensing is used for Non-Destructive Evaluation (NDE) of the structural integrity of metallic structures in the aircraft, railway, oil and gas sectors. Urban water utilities also have extensive large ferromagnetic structures in the form of critical pressure pipe systems made of grey cast iron, ductile cast iron and mild steel. The associated material properties render N...

Abstract:transition and heat affected zones formed during surface remelting (in order to improve wear resistance) with TIGprocess has been investigated. Relationship between various TIG parameters and thickness of remelted and heataffected zones revealed that a high concentrated heat energy is imposed by TIG process which makes it a proper optionfor focused surface treatment. Based on microstru...

In this investigation a new model was developed to calculate gas pressure at the melt/foam interface (Gap) resulting from foam degradation during mould filling in the Lost Foam Casting (LFC) process. Different aspects of the process, such as foam degradation, gas elimination, transient mass, heat transfer, and permeability of the refractory coating were incorporated into this model. A Computati...
