2. 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 ...

   Flange gaskets come in a variety of sizes and are categorized by their inside diameter and their outside diameter. There are many standards in gasket for flanges of pipes. The gaskets for flanges can be divided into four major categories: Sheet gaskets; Corrugated metal gaskets; Ring gaskets; Spiral wound gaskets

   The taper rate for all NPT threads is 1 inch of diameter in 16 inches of length (3 ⁄ 4 inch per foot or 62.5 millimeters per meter) measured by the change of diameter (of the pipe thread) over distance of thread.

6. Graphite - Wikipedia

   en.wikipedia.org/wiki/Graphite

   Graphite consists of sheets of trigonal planar carbon. [20] [21] The individual layers are called graphene. In each layer, each carbon atom is bonded to three other atoms forming a continuous layer of sp 2 bonded carbon hexagons, like a honeycomb lattice with a bond length of 0.142 nm, and the distance between planes is 0.335 nm. [22]

7. Unified Thread Standard - Wikipedia

   en.wikipedia.org/wiki/Unified_Thread_Standard

   The standard designation for a UTS thread is a number indicating the nominal (major) diameter of the thread, followed by the pitch measured in threads per inch.For diameters smaller than ⁠ 1 / 4 ⁠ inch, the diameter is indicated by an integer number defined in the standard; for all other diameters, the inch figure is given.
