Driven Steel Pipe Pile • 100-Ton Capacity • Engineer Refusal Criteria

FMPP100 Pipe Pile System

The FMPP100 Pipe Pile System is a high-capacity driven steel pile engineered for major axial loading, verified refusal criteria, and long-term settlement control in demanding structural applications. The FMPP100 Pipe Pile System is designed for projects where deep foundation performance, installation verification, and deterministic load capacity are critical.

Minimum Allowable Axial Load: 100 tons Pipe: 8″ O.D. Sch 40 steel Steel: ASTM A252 Grade 2 (or approved equal) Wall Thickness: 0.322″ Yield Stress (fy): 35 ksi

FMPP100 Pipe Pile System Material Specifications

Steel Pipe Pile

  • 8″ O.D. Schedule 40 steel pipe
  • ASTM A252 Grade 2 steel (or approved equal)
  • 7′ sections with continuous sections up to 20′ optional
  • Internal mechanical couplers for concentric butt-joint splicing
  • Welded splices or longer solid sections recommended in weak or loose soils

FMPP100 Pipe Pile System Installation Method

The FMPP100 Pipe Pile System uses a controlled two-stage driving sequence for installation and engineer verification.

Stage 1: Pneumatic hammer for initial advancement while monitoring resistance buildup.
Stage 2: Drop hammer to final refusal for precise capacity verification per engineer-defined blow-count criteria.

When specified, additional monitoring such as vibration monitoring can be included in the contract.

Verified Load Capacity of the FMPP100 Pipe Pile System

The FMPP100 Pipe Pile System achieves engineer-verifiable load capacity through controlled drop hammer blow count and refusal criteria established in the project specifications. The FMPP100 Pipe Pile System is intended for major structural support applications where deterministic axial capacity, long-term settlement control, and installation verification are essential.

*Project-specific acceptance may require additional documentation, instrumentation, or testing as dictated by contract, jurisdiction, or the engineer of record.

Heavy Structural Applications for the FMPP100 Pipe Pile System

The FMPP100 Pipe Pile System is designed for the most demanding structural support conditions, including heavily loaded foundations, large structural underpinning programs, industrial facilities, marine-adjacent construction, major commercial projects, and other high-load applications where a 100-ton driven steel pile system is required.
