ASTM A106 is for Seamless Carbon Steel Pipe for High-Temperature Service

This specification covers carbon steel pipe for high-temperature service. These pipes are suitable for welding, bending, flanging, and similar forming operations. Mechanical testing of the specimens shall include tensile, bending, flattening, hydrostatic and nondestructive electric tests. Specimens undergoing bending tests shall consist of sections cut from a pipe. For flattening tests, the specimens shall be smooth on the ends and burr-free, except when made on crop ends. All tests shall be performed in room temperature. If any test specimen shows flaws it can be discarded and substituted for another test specimen. Before testing, if a specimen has scribe scratches, a retest shall be allowed. A retest shall also be allowed if a specimen breaks in an inside or outside surface flaw.

 Carbon Steel Pipe Fittings are a accessories used to connect pipes or other fittings together in a piping systems; these are also made from carbon steel. CS Fittings are pipe fittings that are made up of carbon steel and have sockets attached to their ends for better accommodation of pipe endings into them

Globe valves are linear motion closing-down valves in which the closure member is moved squarely on and off the seat. Usually the closure member is referred as a disc, irrespective of its shape. The seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. Globe valves are most suitable for throttling and controlling fluid flow and are generally employed in small size piping
