2020-10-28 · Boiler tubes for higher temperatures, diameters from 10.2 to 139.7 mm, wall thickness from 0.5 to 16 mm, length 5 – 22 m.
Tube thickness ranges from 3.8mm to 12.7mm & the minimum tube diameter requirement is 22.2mm, the tube surface can be oxidized, rough or pitted (scale-free). The technique permits inspection of the boiler instead of spot checking at up to 15cm/s of scanning speed.
PG-16.3 Minimum Thicknesses It is also important to note that according to PG-16.3 that the minimum thickness of any boiler plate under pressure shall be 1/4in (6mm) except for electric boilers constructed under the rules of Part PEB. PG-27.2.2 Formula to calculate the minimum required thickness: Outside Diameter Equation. Inside Radius Equation

1989-1-1 · Then, the uncleaned semicircle of the tube at the same position is cleaned, so that the circumference of the tube is completely cleaned. DEVELOPMENT OF INSPECTION ROBOT. An annual examination of boiler tubes involves to measure a decrease in wall thickness of the tube due to corrosion at high temperature and a size of bulge caused by a creep.
Example - Boiler Tube: Calculate the minimum required wall thickness of a water tube boiler 2.75 in O.D., strength welded (E, or, e = 0) into place in a boiler. The tube has an average wall temperature of 650°F. The Maximum Allowable Working Pressure (MAWP) is 580 psi gauge. Material is carbon steel SA-192.
