Detail Information
EN 10219 C9 Interlocking Pipe Piles
EN 10219 C9 Interlocking Pipe Piles are cold-formed welded hollow steel pipe piles for structural use. EN 10219 C9 Interlock Piling Pipe is a specialized structural pile used for deep foundation pits, cofferdams, and other support projects. Its core feature is to achieve mechanical interlocking connection through C9 locking, which has advantages such as anti-seepage, anti displacement, and efficient construction.
It is mainly used in fields such as building structures, such as foundation engineering of buildings and support structures of some large buildings.
Different steel grades have different mechanical properties and chemical compositions to meet the needs of different projects.

Advantage Performance Parameters
Verticality Control
The verticality of the first pile after installation is ≤ 0.5%
Water Stop Performance
The precise interlocking of the lock can block the water seepage channels in complex geological layers such as gravel layers
Flexural Strength
Permanent reinforcement plate in the locking area to enhance local stiffness
Anti-corrosion Treatment
Surface zinc layer thickness ≥ 80 μ m, or coated with corrosion-resistant coating
Welding Requirements
The locking buckle is welded using double-sided continuous welds, with a weld leg height of ≥ 8mm
Quality Control
X-ray Testing Online
The online X-ray inspection equipment can detect various defects inside the pipe body, such as cracks, pores, poor welding, etc., to ensure product quality.
Through X-ray inspection, it will not cause any damage to the tested spiral steel pipe.
Hydrotest
The main purpose of Hydrotest is to ensure the integrity of the pipeline system, prevent water leakage, and ensure the normal use of the system. Specifically, measuring water pressure can expose potential issues such as virtual welding, sand holes, and material defects in pipelines through pressure testing. By simulating the sealing and structural integrity of equipment under normal working pressure or overpressure conditions, it effectively prevents safety accidents such as leaks and explosions caused by the failure of pressure bearing components.
Application
1. Deep water cofferdam for cross sea bridges/high-speed railway bridges
2. Subway foundation pit support (pile spacing is usually 1.2m)
3. River regulation, port and dock expansion, sand enclosure projects, etc
