Carbon Steel Welded Pipe

Carbon steel welded pipe is a type of pipe made by forming a flat piece of carbon steel into a cylindrical shape and then welding the seam together. This process involves using a high-energy source to melt the metal at the edges and fuse them. Carbon steel welded pipe is widely used in various industries due to its strength, durability, and relatively low cost compared to other materials.

Types of Welded Steel Pipes:

Straight Seam Welded (ERW/LSAW) Steel Pipes: The weld seam runs straight along the length of the pipe.
Spiral Welded (SSAW)Steel Pipes: The weld seam is spiraled around the pipe.

What Is Welded Carbon Steel Pipe/Tube Application？

Carbon steel welded pipes and tubes are used in high-pressure conditions. They are highly resistant to shock and vibration, making them ideal for transporting fluids. Carbon steel pipes are widely used in a number of industries, such as transporting water and sewage, oil and gas industries, boiler and condenser tubes, high-pressure applications, and chemical processing.
– Transporting water and sewage
– Oil and gas industries
– Boiler and condenser tubes
– High-pressure applications
– Chemical processing

FAQs:

1. What is better, carbon steel vs stainless steel
Carbon pipe steel has high strength and economy, suitable for applications with high pressure and load requirements.
Stainless steel, due to its chromium content ≥10.5%, will also add nickel, molybdenum, and other alloying elements. Therefore, it has good corrosion resistance.

2. Does carbon steel rust in water
Yes. Easy to rust when in direct contact with water. Especially when there is dissolved salt or other corrosive substances in the water, oxidation will occur to form rust. Therefore, surface treatment such as coating a protective layer is required for carbon steel pipes.

3. Based on carbon content, it can be divided into:
Industrial pure iron – carbon content Wc < 0.04% iron-carbon alloy;
Mild steel – carbon content Wc < 0.25%;
Medium carbon steel – carbon content 0.25% < Wc < 0.60%;
High carbon steel – carbon content Wc > 0.60%.
