DeWaLoP - Robust Pipe Joint Detection
In this paper, we describe the vision system for the DeWaLoP (Developing Water Loss Prevention) robot. The robot working environment is inside a pipe (a cylinder), which fits perfectly to the vision system, based on omni-directional cameras. By unrolling the omni-directional camera image to a panoramic image, the circular features of the pipe become linear and by adding a line tracking algorith...
متن کاملHeat transfer enhancement due to air bubble injection into a horizontal double pipe heat exchanger
If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...
متن کاملGray 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...
متن کاملIn-Pipe Inspection Crawler Adaptable to the Pipe interior Diameter
One of the most important requirements of repairing and maintaining of pipelines is the ability to monitor and evaluate the pipe’s interior. In this paper, a novel apparatus to traverse pipes is introduced. The mechanism employs three independent rubber track units which are circumferentially spaced out 120 degree apart symmetrically. The apparatus employs an active mode to adapt to a wide rang...
متن کاملGlobal opportunities in Pipe in Pipe technology
An extensive product range is mandatory to be a key player in the pipe insulation market. The polyurethane preinsulated pipe producers are responding to global opportunities by diversifying their activities into industrial, marine, oil and gas applications. Moreover, the requirements for traditional district heating preinsulated pipes including initial thermal conductivity and its ageing perfor...
