Scope:

This Purchase Description (PD) covers the purchase of supplies with specified components for Dexter Powerhouse cooling water system upgrades, including pipe, fittings, and insulation.

Background:

Dexter Powerhouse cooling water system has experienced numerous leaks over the last few years and needs upgraded. Most, if not all piping and insulation is from original installation and is well past its useful service life. Pipe, fittings, and insulation are not brand specific, but do need to match descriptions and specifications given to ensure the system works as planned.

Requirements:

• Purchase pipe, fittings, and insulation supplies listed below:

Pipe Specifications:

• Pipe must be ASTM A106 grade 50, Schedule 40 seamless, or ASTM A53/A53M seamless, Grade A, Schedule 40.

Welding Fittings:

• Welding fittings shall be the butt weld type. Welding fittings must be black steel conforming to ASME B16.9. Thickness must be same as pipe.

Welding Flanges:

• The flanges must be welding neck or slip-on type. Flanges and flanged fittings must be forged steel, meeting the requirements of ASTM A105/A105M, faced and drilled to ASME B16.5 Class 150 with a 0.0625 inch raised face.

Flange Gaskets:

• Gaskets must be flat, 1/16 or 1/8 inch thick, and contain Aramid fibers bonded with Styrene Butadiene Rubber (SBR) or Nitro Butadiene Rubber (NBR). Gaskets must be the full face or self centering flat ring type.

Valves:

• Provide gate valves with cast-iron bodies with bronze trim.

• Valves must meet the requirements of MSS SP-70, ASTM A126 and have Class 125 flanged end connections.

• Bonnet must be OS&Y Bolted type.

• Discs must be wedge type of iron construction, and have rising stems.

• Valves must be rated for 200 psig service.

• Valves must be equipped with handwheel operators.

Non Shrink Grout:

• Provide non-shrink grout which is inorganic, non-metallic, non-gas-liberating cement-based meeting all requirements of ASTM C1107/C1107M; with a minimum 28-day compressive strength of 5,000 pounds per square inch (psi); and with no shrinkage (0.0 percent) and a maximum 2.0 percent expansion in the hardened state.
