  2. Pipe insulation - Wikipedia

    en.wikipedia.org/wiki/Pipe_insulation

    The application of thermal pipe insulation introduces thermal resistance and reduces the heat flow. Thicknesses of thermal pipe insulation used for saving energy vary, but as a general rule, pipes operating at more-extreme temperatures exhibit a greater heat flow and larger thicknesses are applied due to the greater potential savings.

  3. Testing, adjusting, balancing - Wikipedia

    en.wikipedia.org/wiki/Testing,_adjusting,_balancing

    In heating, ventilation, and air conditioning (HVAC), testing, adjusting and balancing (TAB) are the three major steps used to achieve proper operation of heating, ventilation, and air conditioning systems. TAB usually refers to commercial building construction and the specialized contractors who employ personnel that perform this service.

  4. Heat flux measurements of thermal insulation - Wikipedia

    en.wikipedia.org/wiki/Heat_flux_measurements_of...

    In-situ thermal insulation measurement according to ASTM C0141, applying a heat flux sensor to a boiler wall. On-site heat flux measurements are often focused on testing the thermal transport properties of for example pipes, tanks, ovens and boilers, by calculating the heat flux q or the apparent thermal conductivity.

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Methods of detection include hydrostatic testing, tracer-gas leak testing, infrared, laser technology, and acoustic or sonar technologies. Some technologies are used only during initial pipeline installation and commissioning, while other technologies can be used for continuous monitoring during service.

  6. Thermal conductivity measurement - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductivity...

    The now commonly used procedure, introduced by Eklöf and Gehlin in 1996 and now approved by ASHRAE involves inserting a pipe loop deep into the ground (in a well bore, filling the anulus of the bore with a grout substance of known thermal properties, heating the fluid in the pipe loop, and measuring the temperature drop in the loop from the ...

  7. Hydrostatic test - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_test

    Hydrostatic testing is the most common method employed for testing pipes and pressure vessels. Using this test helps maintain safety standards and durability of a vessel over time. Newly manufactured pieces are initially qualified using the hydrostatic test. They are then revalidated at regular intervals according to the relevant standard.

  8. Duct (flow) - Wikipedia

    en.wikipedia.org/wiki/Duct_(flow)

    For insulation purposes, metal ducts are typically lined with faced fiberglass blankets (duct liner) or wrapped externally with fiberglass blankets (duct wrap). When necessary, a double walled duct is used. This will usually have an inner perforated liner, then a 1–2" (2.5-5 cm) layer of fiberglass insulation contained inside an outer solid pipe.

  9. Pipeline pre-commissioning - Wikipedia

    en.wikipedia.org/wiki/Pipeline_pre-commissioning

    Other services include vacuum drying, degassing, pneumatic testing, barrier testing, leak testing, decommissioning to mention but a few. On the pipeline process pre-commissioning side, there are various services such as chemical cleaning, helium leak detection, bolting, hot oil flushing, pipe freezing, foam inerting etc...
