Sources Sought for HOBAS pipe (centrifugally cast fiberglass-reinforced polymer mortar)

The Government intends to procure, under only one responsible source, where no other suppliers or service will satisfy the agency requirements. The Naval Facilities Engineering Systems Command, Hawaii (NAVFAC Hawaii) is conducting market research to determine if other potential products/services can provide for a centrifugally cast fiberglass-reinforced polymer mortar (CCFRPM) pipe that has the equal performance and listing/approval requirements as the HOBAS pipe (CCFRPM pipe), manufactured by HOBAS Pipe USA, Inc., 1413 E. Richey Road, Houston, Texas 77073-3508. The alternate product/service must meet the following requirements and specifications: Centrifugally cast fiberglass-reinforced polymer (CCFRPM) pipe, manufactured and tested in accordance with ASTM D3262. Pipe sizes shall be 24-inch (DN 600, 25.8-inch OD) and 42-inch (DN 1050, 45.9-inch OD) nominal diameters. Manufactured by the centrifugal casting process to result in a dense, uniform, non-porous, corrosion-resistant, consistent composite structure. Interior surface of the pipe exposed to untreated sewer flow must provide crack and abrasion resistance. Exterior surface of the pipe must be comprised of a sand and resin layer that provides ultraviolet (UV) protection to the pipe exterior. Pipes must be Type 1, Liner 2, Grade 3 per ASTM D3262. Coupling joints must meet the requirements of ASTM D4161. Minimum pipe normal stiffness (SN) when tested in accordance with ASTM D2412 must be 46 pound per square inch (PSI). Resin System: Manufacturer must use only polyester resin systems with proven history of performance in this application. Historical data must be acquired from a composite material or similar construction and composition as the proposed product. Glass Reinforcement: The reinforcing glass fibers used to manufacture the components must be of the highest quality commercial grade E-glass filaments with binder and sizing compatible with impregnating resins. Silica Sand: Sand must be minimum 98% silica wi
