  1. Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless Electric fusion welded steel pipe for High pressure service at moderate temperatures.
  2. One of the two most used steel pipe material for welding, bending and coiling.
  3. Wall thicknesses are mainly Sch 40 (STD) and Sch 80 (XS).
  4. They are either made seamless or seamed using ERW, in Grades A and B. Grade B has higher tensile strength.
  5. Used mainly for utility services. For process piping, A106 is used.
  6. NPS 1⁄8 to NPS 26 [DN 6 to DN 650].
  7. Temperature Range : -15 to 415 deg.C.
  8. There are three types and 5 Grades as shown below.
  9. Type S : Seamless Pipe with Grade A and B based on Carbon Content. A: 0.25% and Grade B : 0.3 Percent. Use A if bending and Closed Coiling to be done. Currently an outdated specification and has been replaced by ASTM A106 specification for seamless carbon steel pipe.
  10. Type E : Electric Resistance Welded with Grade A and B based on Carbon Content. A:0.25% and Grade B: 0.3 Percent. Use A if bending and Closed Coiling to be done.
  11. Type F : Furnace Welded Pipe : With Grade A : 0.3 % Carbon. Not intended for Flanging.
