Carbon Steel Pipes (Carbon Pipes)

Pipe, hollow structure, usually cylindrical, for conducting materials. it is used primarily to convey liquids, gases, solid suspended in a liquid, e.g., a slurry. It is also used as conduit for electric wires. Sometimes it is used a steel structure.

In carbon steel, the main alloying element is carbon. it has higher carbon content, which gives the steel a lower melting point, more malleability and durability, and better heat distribution.
Most commonly used specs are SA/ASTM A106 Gr.B/C;API 5L Gr.B SA/ASTM A53-B; SGP; ASTM A333Gr.6/3; APL 5L X42, 52,60,65,70; ASTM A139 (Spiral Pipe); ASTM 795.
There are also surface treatment for most of Carbon Steel Pipes. Most common are Black Paint and Hot-Dipped Galvanized, where some of pipe derived its name – Black Iron Pipe (B.I Pipes) and Galvanized Iron Pipes (G.I Pipes).
There are two(2) sub-categories for Carbon Steel Pipes. These are Carbon Steel Pipes and Carbon Steel Welded Pipes
Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable, Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.
Welded Pipe is manufactured by rolling metal and then welding it longitudinally across it’s length, therefore welded pipes have a welded joint in it’s cross=section. it can be ERW,EFW,LSAW,SSAW
Below are lists of Carbon Steel Pipes:

(Ssaw) Spiral Carbon Steel Pipe

Seamless Carbon Steel Pipe

ERW Welde Carbon Steel Pipe

LSAW Longitudinal Carbon Steel Pipe



Remarks

  1. The designation of the pipes shall be based on the nominal diameter and nominal wall thickness (schedule number: Sch), However, for the nominal diameter, either A or B shall be used, with the letter symbol A or B suffixed to the figures of nominal diameter for identification.
  2. The mass value shall be calculated from the following formula assuming 1 cm3 of steel to be 7.85 g and rounder off to 3 significant figures in acordance with JIS Z 8401.
    w= D.024 66 t (D=t)
    where W: unit mass of pipe (kg/m)
    t: wall thickness of pipe (mm)
    D: outside diameter of pipe (mm)
  3. The dimensions ecnclosed by the bold-faced lines indicate the pipes most frequently used.
