Foundation Piles for Petroleum / Pipeline

Foundation Piles for Petroleum / Pipeline

MacLeanDixie offers a broad range of steel foundation piles used to support petroleum pipelines.    We offer many time proven solutions with experience in anchoring since the 1920's.  It is important that the product and installation meets stringent requirements to ensure the quality and workmanship of the manufactured product and that installation is performed by qualified and certified technicians to ensure the foundation will perform as expected.

MacLeanDixie has qualified relevant products to meet the IBC (International Building Codes) ICC AC358 Acceptance Criteria for Helical Foundation Systems and Devices.  This should be  important criteria when selecting the supplier to protect your investment for years to come.

A typical helical pile for a raised pipeline support application consists of a 1) lead, 2) one or more extensions and 3) a bracket.

The lead is either a solid round corner square shaft or pipe with one or more helices or circular plates welded to the shaft.  The helices provide the bearing area to support the structure.  The shaft type and size and length are determined by the soil, installation depth and structure load requirement.  The lead is installed with a variety of hydraulic torque motor equipment.  The lead (similar to installing a wood screw into wood) is rotated vertically into the soil to a suitable depth until competent soil is reached to develop the required load bearing capacity.

The location, number and type of helical foundation piles are selected by the engineer or certified MacLeanDixie Distributor or installer.  Torque monitoring by a certified MacLeanDixie installer assures each helical pile is installed to the required specification.
