The difference between spiral steel pipe and seamless steel pipe

Spiral Steel Pipe And Seamless Steel Pipe Supplier-GNEE

Manufacturing process:

Seamless steel pipe: As the name suggests, seamless steel pipe is a steel pipe without welds. It is made by perforating a round solid steel billet, and then through rolling, stretching and other processes to make the wall thickness and diameter of the steel pipe reach the required specifications. The production process of seamless steel pipes does not involve welding, resulting in greater uniformity and integrity.

Spiral steel pipe: Spiral steel pipe is made by rolling a strip of steel plate into a tube shape and spirally welding it at the seam. The production process of spiral steel pipe is relatively simple, the production efficiency is high, and larger diameter steel pipes can be produced. However, due to the presence of welds, the strength and uniformity of spiral steel pipes are relatively low.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

performance:

Seamless steel pipe has high strength, tensile strength and compression resistance due to its uniform material and weld-free structure. Therefore, it is often used in applications that are subject to higher pressures and temperatures, such as piping systems in the oil, gas, and chemical industries.

Due to the existence of welds, spiral steel pipes have relatively low strength and pressure resistance, but they can still meet the needs of most low-pressure transportation systems, such as water, sewage and natural gas. In addition, the production cost of spiral steel pipe is relatively low, so it is more competitive in terms of price.

Application areas:

Seamless steel pipes are widely used in high-pressure and high-temperature applications such as petroleum, natural gas, chemical industry, electric power, and boilers. Due to its excellent properties, seamless steel pipes can also be used to manufacture precision equipment and high-performance parts.
