Specification of PT PIRAMID CAHAYA ABADI Carbon Steel Pipe
KNOW CARBON STEEL STEEL PIPES
In the industrial world, the use of pipes is very dominant. Among other things as a transportation system for various industrial products. Therefore the choice of material is very important considering the fluid to be flowed has different characteristics so that the media (pipe) will adjust.
A. Carbon Steel (Carbon Steel)
Steel is classified according to the chemical composition contained in it. Steel pipes and fittings are an alloy of iron (Fe) and carbon (C), and contain carbon less than 1.7%. Steel classification in three groups, namely: Carbon steel, low alloy steel and high alloy steel.
Carbon steel consists of iron, carbon less than 1.7%, manganese less than 1.65%, amount of silicon (Si), aluminum (Al), and contaminant limits such as sulfur (S), oxygen (O), nitrogen (N ), and there is no minimum limit specified for elements such as Al, Cr, Co, Ni, Mo, Ni [ASM, ASTM A 941].
Carbon steel is the most common pipe material in the power plant, chemical, process, hydrocarbon and industrial pipes industries. The specifications of carbon steel pipes commonly used in steam operation, water or air include ASTM A106 and ASTM A53. The common carbon steel for pipeline applications is the API 5L pipe. Mild steel is carbon steel with a carbon content of less than 0.30%. Medium carbon steel has 0.30% to 0.60% carbon. High carbon steel has carbon above 0.6%.
B. Alloy Steel (Alloy Steel)
Alloy steel is steel that contains a number of alloying elements,
such as 0.3% chromium (Cr), nickel 0.3% (Ni), molybdenum 0.08% (Mo), etc.
[ASTM A 941]. Low alloy steel is alloy steel containing less than the minimum percentage of alloy defined.
