  • Insulation and Liquified Natural Gas In Production and Storage
    and wall insulation. The design engineer should prepare in each case the appropriate drawing. An LNG storage facility can have over 30,000 linear feet of cryogenic piping that requires insulation. These lines range in size, but typical sizes for primary unloading lines are 12-, 18-, 20-, and 24-inch
  • Typical Properties of Multi/Cable Insulations
    temperature limit is dependent upon the wall thickness and the diameter of the construction. As both of these parameters increase, the susceptibleness to cracking or flexing at low temperatures also increases. TFE. It is non-polar and has outstanding electrical properties. The good electrical
  • Thermal Imaging Scan Reveals the Truth Behind the Wall
    ), and the exterior weatherproofing paper had already been applied. The builder was questioned on how this exterior portion of a wall was insulated as the insulation was put in after the weatherproofing was applied.
  • NFPA 285-2006 Approval for Wall Assemblies Using Foam Plastic Insulation (.pdf)
    SPF insulating foams, or rigid board. The wall assembly shall be tested in accordance. stock insulations of EPS, XPS and ISO. with and comply with the acceptance. chemistries. Type IV and Type X extruded. criteria of NFPA 285. Exception: One-story. polystyrene and polyisocyanurate insulation
  • New Insulation Material Yields Smaller, Lighter, Greener Cables (.pdf)
     . polyethylene. Along with the reduced wall thickness, the low specific gravity . yields significant weight savings of around 25%. . • Flame resistance. mPPE meets UL VW‐1. . • Wide temperature range. Wires and cable with mPPE insulation meet UL 1581 . requirements for operation at 80°C and 105°C
  • Inspecting Gas Fired Furnaces Using Infrared Thermography
    shutdowns of these furnaces can result in production losses as high as $84K. Traditionally, visual inspections have been the preferred method of monitoring wall insulation health. Peeled or blistered paint and a cherry red glow are used as indicators that insulation is breaking down inside
  • Capacitive Sensors Help Solve Difficult Level Applications (.pdf)
    Capacitive sensors can sense through lower dielectric materials, such as plastic or glass, to detect higher dielectric materials, like liquids. This allows capacitive sensors to detect the level of numerous materials directly through the wall of a plastic or glass container, or by utilizing a sight
  • Medical Device Link .
    for paired wires capable of transmitting to 100 MHz, are typical. A 24-gauge wire, approximately 0.020 in., receives an insulation of 0.0065 in. with outside diameter (OD) tolerances of +-0.0001 in. Specifications further require a minimum concentricity (minimum wall/ maximum wall) of >=95%. Almost
  • Medical Device Link .
    of the seamless design. Seamless polyimide tubing was introduced to the catheter market in the early 1980s. One of the most commonly asked questions in the catheter design market is, "how thin can the wall be made? " The limiting factor in making thin walled polyimide tubing for medical applications
  • Medical Device Link .
    engineers define the minimum thickness of insulation material needed around a wire conductor. Very few extruded polymers have the capacity to provide adequate dielectric strength from 0.001 in. of insulation wall thickness (see Table I). Dielectric testing involves twisting two wires together
