This is the most common and cheapest material used in process plants. Carbon steels are used in most general refinery applications. It is routinely used for most organic chemicals and neutral or basic aqueous solutions at moderate temperatures. Carbon steels are extensively used in a temperature range of (-) 29 degrees centigrade to 4270 centigrade

Low-Temperature Carbon steel pipes
Linghang can be used at a low temperature of (- 45.5) degrees centigrade. Killed Carbon Steel is defined as those which are thoroughly deoxidized during the melting process. Deoxidation is accomplished by the use of silicon, manganese, and aluminum additions to combine with dissolved gases, usually, oxygen, during steelmaking. This results in cleaner, better-quality steel which has fewer gas pockets and inclusions. Killed carbon steel is specified for major equipment in the following services to minimize the possibility or extent of hydrogen blistering and hydrogen embrittlement:
·where hydrogen is a major component in the process stream.
·where hydrogen sulfide H2S is present with an aqueous phase or where liquid water containing H2S is present.
·Process streams containing any amount of Hydrofluoric acid (HF), boron trifluoride (BF3), or (BF) compounds; or
·Monoethanolamine (MEA) and diethanolamine (DEA) in solutions of greater than 5 weight percent.
Features
Carbon steel pipes are safe to handle and work with. They are inflammable and resistant to corrosion even in environments that are acidic. With superior shock resistance, carbon steels hold up better than other pipes when laid underground. Their high tensile strength is ideal for high pressure applications. This means carbon steels have a higher carrying capacity than other materials with the same diameter, thus more cost effective. General applications include water, oil and gas piping, sewage, scaffolding, building construction, furniture, vehicle, civil engineering, escalators, elevators, and other general usage.
