Difference between Carbon Steel Welded Pipe and Carbon Steel Seamless Pipe

Piping components in a carbon steel grade are produced in seamless and welded configurations. Both these types can be distinguished from certain characteristics.

• Carbon Steel Seamless Pipe is produced by passing precisely shaped hot billets through an extruded metal. A welded pipe is produced by welding pieces of sheets or strips.
• A seamless pipe has a 20% higher load-bearing capacity and strength compared to a Carbon Steel Welded Pipe.
• Welded pipes can be produced in a range of sizes and dimensions. Seamless pipes are restricted to up to 24 inches.
• Seamless Carbon Steel Tube has thicker and stronger walls. Welded tubes have thinner and lighter walls.
• The welds or seams on Carbon Steel ERW Pipe are prone to rust; however, seamless pipes have good resistance to corrosive media.
• Welded carbon pipes are cheaper than carbon seamless pipe grades.

Difference between High/ Low/ Medium/ Fully Killed/ Normalized/ Plain and Quenching carbon steel pipe

The content of carbon in steel helps in categorizing these components. A Low Carbon Steel Pipe is designed with a carbon content of less than 0.30%. A medium carbon grade is made up of a carbon content between 0.30% to 0.60%, while a high carbon grade has over 0.60% of carbon embedded in them. The higher the carbon content higher is its strength, but the ductility is lower. A fully killed Large Diameter Carbon Steel Pipe is thoroughly deoxidized by the removal of oxygen during the process of melting. The steel has dissolved oxygen after it is converted to solid iron. A normalized carbon steel pipe is obtained by heating it to reach the austenite phase followed by cooling. These pipes exhibit superior strength and ductility compared to annealed steel. In a quenched carbon pipe the crystal structure of the module is changed, making them harder or brittle. A plain pipe in this grade is the original grade and has not been processed further.

Why buy from Carbon Steel Pipe manufacturers in India?

Manufacturers and suppliers of carbon steel pipes in India have access to abundant raw materials and labour. This reduces the rate of the SCH 40 Carbon Steel Pipe. The factories and centers in India are equipped with the best facilities and technological systems, further ensuring quality products. The strategic location of India helps in better transportation and providing enhanced logistical support for High Yield Carbon Steel Pipe.

Difference between SAW Carbon Steel pipes and Carbon Steel ERW pipes?

• The welding seam of a carbon steel ERW pipe is flat and smooth. SAW carbon steel pipe is utilized for internal or external weld reinforcement.
• The solvent deposits on SAW pipes result in large volumes of defects. ERW pipes show few defects as the pipes are wire lined or straight welded.
• ERW carbon pipes residual stress ratio is lower or less than SAW pipes.
• When the grade becomes defective, the ERW pipe can be re-welded. Any processing on a defective SAW pipe will lead to corrosion or cracking.
