2. Pipe dope - Wikipedia

   en.wikipedia.org/wiki/Pipe_dope

   Petroleum-based pipe dope is not intended for use on threaded PVC, CPVC or ABS pipe and fittings since it will deteriorate the plastic. Builders in the US are expected to use thread compounds that meet ASTM F2331 - Standard Test Method for Determining Chemical Compatibility of Thread Sealants with Thermoplastic Threaded Pipe and Fittings Materials or thread seal tape on PVC, CPVC and ABS threads.

3. Gasket - Wikipedia

   en.wikipedia.org/wiki/Gasket

   Spiral wound gaskets are also used in high pressure pipelines and are made with stainless steel outer and inner rings and a center filled with spirally wound stainless steel tape wound together with graphite and PTFE, formed in V shape. Internal pressure acts upon the faces of the V, forcing the gasket to seal against the flange faces.

4. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   PTFE tape used for different sized fittings PTFE tape for natural gas. There are two US standards for determining the quality of any thread seal tape. MIL-T-27730A (an obsolete military specification still commonly used in industry in the US) requires a minimum thickness of 3.5 mils and a minimum PTFE purity of 99%. [3]

5. Dry lubricant - Wikipedia

   en.wikipedia.org/wiki/Dry_lubricant

   The quality of natural graphite varies as a result of the ore quality and its post-mining processing. The end product is graphite with a content of carbon (high grade graphite 96−98% carbon), sulfur, SiO 2, and ash. The higher the carbon content and the degree of graphitization (high crystalline) the better the lubricity and resistance to ...

6. Graphite - Wikipedia

   en.wikipedia.org/wiki/Graphite

   The expanded graphite can be used to make graphite foil or used directly as a "hot top" compound to insulate molten metal in a ladle or red-hot steel ingots and decrease heat loss, or as firestops fitted around a fire door or in sheet metal collars surrounding plastic pipe (during a fire, the graphite expands and chars to resist fire ...

7. Annealed pyrolytic graphite - Wikipedia

   en.wikipedia.org/wiki/Annealed_pyrolytic_graphite

   Annealed Pyrolytic Graphite (APG), also known as Thermally Annealed Pyrolytic Graphite (TPG), [1] is a form of synthetic graphite that offers excellent in-plane thermal conductivity. As with pyrolytic carbon or pyrolytic graphite (PG), APG is also low in mass, is electrically conductive , and offers diamagnetic properties that allow it to ...

8. Expandable graphite - Wikipedia

   en.wikipedia.org/wiki/Expandable_graphite

   To produce expandable graphite, natural graphite flakes are treated in a bath of acid and oxidizing agent.Usually used oxidizing agents are hydrogen peroxide, potassium permanganate or chromic acid. Concentrated sulphuric acid or nitric acid are usually used as the compound to be incorporated, with the reaction taking place at temperatures of ...

9. Materials for use in vacuum - Wikipedia

   en.wikipedia.org/wiki/Materials_for_use_in_vacuum

   Torr-Seal, or its generic equivalent Hysol-1C (US brand name) or Loctite 9492 (EU brand name), is an epoxy with resin and hardener for use in vacuum environments. It will begin to degrade at high temperatures but otherwise is very stable with very little outgassing. Other vacuum-rated epoxies are also available.
