Spiral welded steel pipes for piles are made from hot-rolled steel strip coils, which are often warm-spiral formed and double-sided submerged arc welded or made. They are used for steel pipes for foundation piles in civil construction structures, docks, bridges, etc. The main reference standard is SY/T5040-2008 (spiral welded steel pipe for piles).
Main specifications: pipe diameter range: diameter 325mm-2400mm, wall thickness range 8-60mm, length range 6-12m.
It is a steel pipe made of rolled and welded steel plates with a highly spiral structure. The diameter of this steel pipe is generally 630 mm, and the length can be customized according to needs.
The characteristics of 630 spiral welded steel pipe for piling are high strength, corrosion resistance and anti-aging, which can effectively improve the service life and safety of the building.
So, what are the specific applications of 630 spiral welded steel pipes for piling in the construction industry?
First of all, it is widely used in infrastructure construction fields such as bridges, highways, and docks. In these areas, steel pipes need to withstand high strength and fatigue resistance to ensure the stability and safety of infrastructure. Secondly, it is also used in pile foundation projects of buildings, such as houses, factories and other buildings. In these buildings, steel pipes need to have a high degree of corrosion resistance and aging resistance to cope with various complex environmental conditions.
