Both steel pipe piles and spiral steel pipes are common building materials, and they both play an important role in construction projects. Although they are all steel products, there are still some differences between them. This article will focus on the differences between steel pipe piles and spiral steel pipes in detail.

Definition

A steel pipe pile is a type of steel pipe used for foundation treatment, which is made of steel pipe, usually of circular or square cross-section. Spiral steel pipe is a steel pipe used in construction projects, which is made of spiral steel plate, usually with a circular cross-section.

Manufacturing process

The manufacturing process of steel pipe piles mainly includes processes such as cold forming, welding and heat treatment. The manufacturing process of spiral steel pipe mainly includes coiling, welding, and straightening processes.

Use

Steel pipe piles are mainly used for foundation treatment, including bridges, docks, tunnels, buildings and other projects. Spiral steel pipes are mainly used in pipelines, bridges, tunnels, buildings and other projects in construction projects.

Performance

Steel pipe piles have high strength and rigidity and can withstand large loads and deformations. The strength and rigidity of the spiral steel pipe are lower, but its sealing and corrosion resistance are better.

Installation method

The installation methods of steel pipe piles mainly include vibratory pile sinking, static pressure pile sinking, and bored piles. The installation methods of spiral steel pipe mainly include direct buried and immersed tubes.

Price

The price of steel pipe piles is relatively high, mainly because of its complicated manufacturing process. The price of spiral steel pipe is relatively low, mainly because its manufacturing process is relatively simple.

Advantages and disadvantages

The advantage of steel pipe piles is that they have high strength and rigidity, and can withstand large loads and deformations; the disadvantage is that the price is relatively high. The advantage of spiral steel pipe is that it has good sealing and corrosion resistance, and the price is relatively low; the disadvantage is that its strength and rigidity are low.

To sum up, steel pipe piles and spiral steel pipes are common building materials, and they both play an important role in construction projects. Although they are all steel products, there are still some differences between them. When choosing building materials, it is necessary to choose the appropriate material according to the specific engineering needs.
