Spirally welded steel pipes

Innovations in Construction: The Benefits of Spirally Welded Steel Pipes

Steel tubes used in foundation works, either as piles or as king piles of a combined wall system. These are spirally welded and manufactured in our mill in the Netherlands.

Spiral Mill Projects Europe’s spiral mill is located on its site in Dintelmond (The Netherlands). This mill is especially designed for the production of spirally welded pipes for foundation purposes.

Our strong points are: 

  • Production is 100% controlled and certified with delivery of 2.2, 3.1 or 3.2 certificates according EN 10204. 
  • Pipes can be produced with diameters up to 2850mm and wall thicknesses up to 25.4mm (30.0mm for steel grades up to S355). 
  • We can provide pipes in all requested steel grades due to our worldwide network of coil producers. 
  • Pipes can be produced with lengths up to 65m without circumferential weld. Longer tubes can be achieved by welding. 
  • There is a coating facility present on our production site. 
  • Several specialized welding facilities are placed in line with the spiral mill for executing specific works like welding clutches or other steel parts and making butt welds.

The advantages of AZ sheet piles in combined walls are: 
  • Load-displacement behaviour is far better than that of double and triple U-piles, so settlements are less. 
  • High soil and water pressures are increasingly transferred to the pipe as normal tensile stresses (membrane effect). 
  • Because of their geometry, AZ intermediate sheet piles are coping better with driving deviations of the pipes than U-piles, because of the triple hinge system. 
  • Larssen-type interlocks contribute to the high performance of AZ intermediate sheet piles. 
  • In tests is measured that AZ intermediate sheet piles can resist very high ultimate loads, for example up to 57m hydraulic head for an AZ 18 (S 430 GP).
