About this file
This document is a detailed specification for coated steel pipe piles for the US Coast Guard, outlining precise manufacturing, coating, and delivery requirements. The specification covers two steel pile sizes - 18-inch and 12.75-inch outside diameter - both made from ASTM A252, Grade 2 steel with specific requirements including 0.5-inch wall thickness, straight seam welding, and allowable splice conditions. Coating requirements mandate blast cleaning, application of an Organic Zinc Primer (2 mils dry film thickness), and a Black Coal Tar Epoxy-Polyamide topcoat (16 mils dry film thickness), with both coats from the same manufacturer to ensure compatibility.
Delivery and quality assurance terms are stringent, requiring delivery within 30 days after task order award, weekday delivery between 8:00 a.m. and 3:00 p.m. (excluding federal holidays), and comprehensive inspection for manufacturing defects. Each pipe pile must be legibly marked with manufacture details including year, manufacturer name, heat number, manufacturing process, outside diameter, wall thickness, weight, length, grade, and specification number. The specification allows for touch-up of damaged coating systems and limited welding repair of defects, with rejection of piles possible if one or more specified defect criteria are not met.

SPECIFICATIONS FOR COATED STEEL PIPE PILES
SCOPE: The contractor shall provide all materials and services necessary to procure, deliver, and oƯ-load coated steel pipe piles to the specified Coast Guard facility.
REFERENCES:
(1) ASTM A 252 (2010) – Standard Specification for Welded and Seamless Steel Pipe Piles
(2) SSPC PS 11.01 (1982; E 2004) Black (or Dark Red) Coal Tar Epoxy-Polyamide Painting System
(3) SSPC PS 12.01 (2002; E 2004) OneCoat Zinc-Rich Painting System
(4) SSPC SP 6/NACE No. 3 (2007) Commercial Blast Cleaning
(5) SSPC Paint 16 (2006) Coal Tar Epoxy-Polyamide Black (or Dark Red) Paint
(6) SSPC Paint 20 (2002; E 2004) Zinc-Rich Primers (Type I, Inorganic, and Type II, Organic).
SUBMITTALS:
(1) Certificate of conformance to standards for the steel piles,
(2) Manufacturer’s literature for the Organic Zinc Primer and the Black Coal Tar Epoxy- Polyamide paints to be approved by a Coast Guard technical representative.
18” STEEL PILE REQUIREMENTS: Piles shall be produced with an 18 inch OUTSIDE DIAMETER. All piles shall be ASTM A252, Grade 2 with plain ends and shall be straight seam welded. One splice per pile may be used if it is located within 10 feet of either end of the pile and tension test specimens from sample splices conform to the strength requirements of Table 1 of ASTM A252. Welds shall be ground down such that they are smooth and flush with the pile exterior. A certificate indicating that the piling was manufactured and tested in accordance with this specification shall be mailed to the Contracting OƯicer at the time of delivery. Steel piles shall be furnished in the lengths and diameters (outside) as listed in the contract. Pile length tolerance shall be (+/-) 3 inches.
The wall thickness of all steel piles shall be 0.5 inches. The piles shall be coated as specified below.
12” STEEL PILE REQUIREMENTS: Piles shall be produced with a 12.75 inch OUTSIDE DIAMETER. All piles shall be ASTM A252, Grade 2 with plain ends and shall be straight seam welded. One splice per pile may be used if it is located within 10 feet of either end of the pile and tension test specimens from sample splices conform to the strength requirements of Table 1 of ASTM A252. Welds shall be ground down such that they are smooth and flush with the pile exterior. A certificate indicating that the piling was manufactured and tested in accordance with this specification shall be mailed to the Contracting OƯicer at the time of delivery. Steel piles shall be furnished in the lengths and diameters (outside) as listed in the contract. Pile length tolerance shall be (+/-) 3 inches.
The wall thickness of all steel piles shall be 0.5 inches. The piles shall be coated as specified below.
COATING REQUIREMENTS: Blast clean each pile in accordance with SSPC SP 6. Apply one coat Organic Zinc Primer, meeting SSPC Paint 20 Type II, coat to all surfaces not more than 2 hours after blast cleaning. Organic Zinc Primer shall be applied in accordance with SSPC PS 12.01 to 2 mils DFT. Apply Black Coal Tar Epoxy- Polyamide meeting SSPC Paint 16 to all surfaces after the primer coat is fully dry. The Coal Tar Epoxy-Polyamide shall be applied in accordance with SSPC PS 11.01 to a minimum to 16 mils DFT. Both the prime coat (Zinc Primer) and the topcoat (Coal Tar Epoxy) shall be from the same manufacturer to ensure system compatibility.
MARKING REQUIREMENTS: Each pipe pile shall be legibly marked by stenciling (white paint) or stamping the following information: year of manufacture, name of manufacturer, heat number, manufacturing process (i.e.: seamless, flash welded, fusion welded, or electric resistance welded), outside diameter and nominal wall thickness, weight, length, grade, and the specification number. The letters shall not be less than ¾ inch high, if stenciled, and not less than ¼ inch high if stamped. The required data shall be marked on both ends of each pile.
QUANTITIES/DELIVERY LOCATION:
As shown in accompanying requests.
DELIVERY LIMITATIONS: None.
DELIVERY SCHEDULE: Delivery of piles shall be within 30 days after the task order is awarded to the location specified above. The contractor shall notify the consignee at least 3 working days before delivery of piles. Delivery shall be made during weekdays between the hours of 8:00 a.m. and 3:00 p.m. No delivery on federal holidays.
QUALITY ASSURANCE: Each pile shall be examined for the following defects upon delivery: (1) Pile not manufactured as specified and in accordance with ASTM A252, (2) Diameter varies more than (+/-) 1% from the specified diameter (including outside diameter at welds), (3) The weight of any pile is more than 15% heavier nor 5% lighter than that prescribed in Table 2 of ASTM A252, (4) Nominal wall thickness at any point is less than 12.5% under that specified, (5) Pipe pile not reasonable straight, (6) Surface imperfections exist with a depth exceeding 25% of the nominal wall thickness, and (7) Coating system is severely damaged upon delivery and unloading. The presence of one or more of these defects shall be cause for rejection of the pile. Damaged coating systems may be ‘touched-up’ by the contractor in accordance with the manufacturer’s recommendations to meet these requirements. Repair of defects by welding is permitted only when the depth is not more than 33% of the nominal wall thickness.
