What is Mild Steel Pipe (MS Pipe)?
Mild Steel (MS) Pipe is manufactured using low carbon steel (less than 0.25%). Due to the low carbon content, the steel pipe does not harden and is easy to work with. Since mild steel pipe is made of low carbon steel, it can be easily welded and formed into pipes and tubes of various shapes and sizes. These pipes are mainly used in industries and engineering applications where corrosive fluids are used. In addition, MS pipes are also used in drinking water supply, i.e., pipes, fire protection, and HVAC (heating, ventilation, and air conditioning). Mild steel does not corrode because its surface is coated with paint, varnish, and other metals, which makes it durable and can work in very harsh conditions. In addition, mild steel pipes can also withstand certain temperatures.
Cold drawn and hot rolled steel bars belong to mild steel. Hard steel and mild steel are divided according to whether they have a yield point or not, because hard steel has no obvious yield point and plasticity, and its control stress coefficient is lower than mild steel compared to mild steel.
Characteristics of MS pipe
Low carbon steel pipe has the characteristics of high tensile strength, conforming to the American Society for Testing and Materials (ASTM) standards, high strength, low carbon content, easy welding, simple manufacturing, easy use, low price relative to other metals, and service life of more than 100 years. The main application areas of low carbon steel pipes include structural pipes, mechanical pipes, ordinary building pipes, residential pipes, planned transportation pipes, fence pipes, building structure pipes and water steel pipes.
Low carbon steel square pipes have the advantages of high quality, corrosion resistance, high strength and strong deformation ability. The application areas of round low carbon steel pipes are very wide, such as modern water pipes, factory pipes, agriculture and water supply systems, excitement steel fences, street barriers, stop boundaries, fences, steel doors and steel windows, roadside railings, foundations and construction projects, water pipelines, etc.
How to distinguish American standard carbon steel pipes by carbon content
American standard
carbon steel pipes rely on adjusting the carbon content (C) to improve the mechanical properties of steel. Therefore, according to the carbon content, this type of steel can be divided into:
Low carbon steel--the carbon content is generally less than 0.2%, such as ASTM106A, ASTM106B ASTMA53A ASTMA53B steel, etc. Medium carbon steel--the carbon content is generally between 0.2~0.70%, such as ASTM210C ST52.4 steel, etc.;
High carbon steel--the carbon content is generally greater than 0.70%. This type of steel is generally not used to manufacture American standard carbon steel pipes, but is mostly used for round steel and bars.
