Holiday detection in FBE Pipe Coating Finishing

How big is air gap in FBE coatings?How big is air gap in FBE coatings?This will usually find holidays that are through the coating with exposed steel, assuming the coating is not cratered. This means that the coating is deformed from the impact and is thicker at the edges leaving an air gap of maybe 21 mils. These often will go undetected at the 125 volts per mil.Holiday detection in FBE Coatings on Pipe How big of a coating do I need for holiday detection?How big of a coating do I need for holiday detection?Holiday detection in FBE Pipe Coating. Coatings are usually applied in the 14-16 mil thicknesses providing a minimum of 15,000 volts of protection. At 125 volts per mil at 14 mils is 1750 volts. This will usually find holidays that are through the coating with exposed steel, assuming the coating is not cratered.Holiday detection in FBE Coatings on Pipe Pipeline Construction Quality Issues and Solutions

holidays are patched, and just before pipe is lowered into the ditch-- reinspect. Check for appropriate coating thickness. Utilize holiday detector with voltage setting (FBE 2,000 volts DC, dual coat & two part epoxy 100 volts DC per mil of coating) shall be verified. The holiday detectors batteries must be checked daily and replaced/recharged if required.

What is the function of the FBE coating?What is the function of the FBE coating?Corrosion control of the FBE coating is a function of the coatings ability to provide a barrier against water, oxygen, chloride, and other aggressive elements which prevent permeation through the coating film to attack the steel substrate.Fusion Bonded Epoxy Coating of Steel IspatGuru(PDF) FBE powder and coating tests evaluated

Properties of a fusion-bonded epoxy (FBE) external pipeline coating can be significantly affected by the conditions under which the FBE powder has been stored. Nova, An Alberta Corporation, and 3M Holiday detection in FBE Pipe Coating Finishing(PDF) Manufacturing of Pipes, Coating and Testing Parameter Holiday inspection Each Pipe is checked at 5V per microns of specified coating thickness or 25 kV as specified for detecting any discontinuity in coatings by suitable DC based Holiday detectors.

Jul 13, 2019The FBE coating is also to be abraded around the areas to be coated 15 mm to 25 mm out from the edge of the holiday and all dust removed before applying the patch coating. The patch coating is to be applied as per the recommendations of the FBE coating material supplier to a minimum thickness of 0.65 mm with an overlap with the existing sound coating by a minimum of 25 mm.Holiday DetectorHigh voltage holiday detection. High voltage holiday test is normally used to determine the existences of discontinuities in coating films. The high voltage, or porosity technique, can be used to test coatings up to 25mm (1") thick and is ideal for inspecting pipelines and other protective coatings. Coatings on concrete can also be tested using this method. There are two types of high voltage holiday detectors- Continuous DC and Pulsed DC. Continuous DC Holiday DetectionHoliday detection in FBE Coatings on Pipe - FinishingSep 12, 2012Todays FBE's have a dielectric strength of 1100 to 1300 volts per mil. Coatings are usually applied in the 14-16 mil thicknesses providing a minimum of 15,000 volts of protection. At 125 volts per mil at 14 mils is 1750 volts. This will usually find holidays that are through the coating with exposed steel, assuming the coating is not cratered.
