Seamless Pipe vs. Welded Pipe: Understanding the Differences
When it comes to selecting piping for your industrial needs, two options commonly arise - seamless and welded pipes. Both types remain prevalent in the market, but it is crucial to determine which one is suitable for specific applications.
Let’s delve deeper into the differences between seamless pipe vs. welded pipe.
Seamless Pipe:
Seamless pipes are made from a solid cylindrical steel billet, which is heated and then formed into a pipe through a piercing process. This process guarantees a uniform composition throughout the entire pipe. Seamless pipes have no welded seams and are suitable for applications requiring high pressure, high-temperature environments, or those where welding is not possible. They are also ideal for critical applications where high-quality pipes are essential, such as the pharmaceutical and oil and gas industries. Additionally, seamless pipes have a smooth interior surface, which reduces friction and makes them suitable for applications that require the efficient flow of liquids or gases.
Welded Pipe:
Welded pipes are created through the welding of a steel plate or coil into a cylindrical shape. The welding process involves applying heat to the edges of the plate, melting it together, and cooling it down. This process may result in a weaker pipe; however, the use of high-quality materials and careful manufacturing can result in a strong enough pipe for most applications. Welded pipes have welded seams and are more cost-effective than seamless pipes. They are commonly used in less critical applications such as transportation of oil, gas or water, and structural applications including furniture, handrails, and more.
When selecting pipes for specific applications, it is important to take into account parameters including size, pressure, temperature, and materials. Ultimately, both seamless and welded pipes have their unique advantages, and it is important to choose the most appropriate one for a particular application.
