  • Two Detector Solution to Analyzing Sulfur

    Sulfur compounds are reactive, corrosive to pipes, and destructive to catalysts in petroleum refineries. Sulfur emission are strictly regulated globally. When released into the atmosphere sulfur dioxide converts to sulfuric acid resulting in adverse effects on human health and the environment. Sulfur detection is found useful in many other industries; therefore, detection of sulfur compounds in ...

  • Completing Condition Assessments using In-pipe GPR as Pipe Penetrating Radar

    Abstract This paper describes the development of Pipe Penetrating Radar (PPR), the underground in-pipe application of GPR, a non-destructive testing method that can detect defects and cavities within and outside mainline diameter (>18 in / 450mm) non-metallic (concrete, PVC, HDPE, etc.) underground pipes. The method uses two or more high frequency GPR antennae carried by a robot into ...

  • Effect of Rib Spacing on Deformation of Profile-Wall Plastic Pipes Buried in Coarse Granular Backfill

    Several different types of plastic pipe products were instrumented, buried in coarse granular backfill, and subjected to monotonic, distributed load in the field. During each field test, data were recorded from strain gages, linear variable differential transformers, and earth pressure cells by computerized data acquisition units.Review of the deflection data from 14 tests revealed a pattern on ...

  • Combined bulk and wall reactions in turbulent pipe flow: decay coefficients and concentration profiles

    This study discusses the effect of combined first-order, bulk and wall reactions on the overall intensity of mass withdrawal in smooth pipes. A one-dimensional model for the transport of high Schmidt number compounds (where the Schmidt number is the ratio of the fluid viscosity to the solute diffusivity) is extended with the effect of a first-order bulk reaction. Profiles of velocity and eddy ...

  • Granulators for Size reduction of pipes up to 6 meter (20 ft.) length

    Neue Herbold SR series granulators are designed and manufactured for the size reduction of full length profiles and pipes eliminating the need to pre-cut the material into shorter lengths. The 6000 mm (20ft.) profiles or pipes are fed horizontally into the granulator. The SR series granulators are used for applications ranging from profiles to extremely thick walled PVC, PP and PE pipes. The SR ...

  • Entropy analysis of laminar-forced convection in a pipe with wall roughness

    Momentum and heat transfer rates, as well as entropy generation have been numerically investigated for fully developed, forced convection, laminar flow in a micro-pipe. Compressible and variable fluid property continuity, Navier-Stokes and energy equations are solved for various Reynolds number, constant heat flux and surface roughness cases; entropy generation is discussed in conjunction with ...

  • Numerical investigation of entropy generation in an unsteady flow through a porous pipe with suction

    This paper investigates the entropy generation rates in an unsteady flow of a variable viscosity incompressible fluid through a porous pipe with uniform suction at the surface. The nonlinear governing equations for momentum and energy balance are derived and solved numerically using a semi–implicit finite difference scheme in order to obtain the fluid velocity and temperature profiles. Numerical ...
