2. Pipe plug - Wikipedia

   en.wikipedia.org/wiki/Pipe_plug

   A pipe plug is a tool or material for the temporary sealing of pipelines in sewerage and other liquid and gas transportation systems; typically for maintenance or non-pressurized line testing. A pipe plug is also known as an inflatable plug, [1] mechanical pipe plug, [2] pipe test plug, pipeline isolation plug, expandable plug, pipe bung, pipe ...

3. Compression seal fitting - Wikipedia

   en.wikipedia.org/wiki/Compression_seal_fitting

   In mechanical engineering, a compression seal fitting, also known as a sealing gland, is intended to seal some type of element (probe, wire, conductor, pipe, tube, fiber-optic cable, etc.) when the element must pass through a pressure or environmental boundary. [1] A compression seal fitting may serve several purposes:

4. 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.

5. Piping and plumbing fitting - Wikipedia

   [18]: 71 The rubber sleeves are typically secured with stainless steel worm drive clamping bands, which compress the rubber to make a tight seal around the pipes and fittings. These pipe clamps are similar to hose clamps, but are heavier-duty and ideally are made completely of stainless steel (including the screw) to provide maximum service life.

6. Seal (mechanical) - Wikipedia

   en.wikipedia.org/wiki/Seal_(mechanical)

   A seal is a device or material that helps join systems, mechanisms or other materials together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets .

7. 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.
