PERFORMANCE WORK STATEMENT (PWS)

FOR

AIR STORAGE AND CYLINDERS

EXPLOSIVE ORDNANCE DISPOSAL TRAINING AND EVALUATION UNIT TWO

1. Scope:

Explosive Ordnance Disposal Training and Evaluation Unit TWO (EOD TEU 2) is the east coast training center for Explosive Ordnance Disposal group TWO (COMEODGRU TWO) and their subordinate units. In order to better support and train the various units that rely on EOD TEU 2 a permanent dive locker is being stood up in Key West, FL. In order to provide consistent diver’s air an air storage installation is required. The storage will consists of four (4), 5000psi flasks, augmented with two (2) charging panels for cascading to diver’s bottles and one (1) 6000psi charging hose.

2. Requirements:

ASME STORAGE SYSTEMS

A properly sized air storage system is as important to a compressed air system as is a properly sized air compressor. An air storage system can greatly increase the overall efficiency of the compressed air system. Storage systems that have been properly matched to the compressor’s capacity can save on compressor maintenance and down time.

These cylinders shall conform to the ASME (American Society of Mechanical Engineers) codes for permanent installation. The vessels shall be fabricated and stamped in accordance with SECTION VIII, DIVISION 1 of the latest edition of the ASME code for unfired pressure vessels for non-corrosive service. Each vessel shall have a volume of:

- 436 cubic feet at 5,000 PSI with a safety factor of 4 to 1

- 491 cubic feet at 6,000 PSI with a safety factor of 3 to 1 Capacities are approximated based on 70º F

All storage systems shall be in accordance with OSHA 29 CFR 1910.169, which, in part, states that each pressure vessel must have an indicating pressure gauge, a spring loaded safety valve and moisture drain valve.

Cylinder specifications

- Either BAUER Part Number or similar to: CYL-0009

- Working Pressure: 5000 PSI / 6000 PSI

- Test Pressure: 7875 PSI / 10500 PSI

- Cylinder weight: 400 lbs.

- Cylinder material: Steel ASME SA 372 Class V Type A AISI 4130

- Cylinder height: 54” without valve

- Cylinder diameter: 9 5/8”

- Finish: Interior Grit Blasted, Exterior Grit Blasted and Primed and Painted

Scope of Supply

Model CYL-0009 - one ASME cylinder only Model ASME5K - an ASME air storage assembly for 5000 PSI service Model ASME6K - an ASME air storage assembly for 6000 PSI service

The Scope of supply for ASME5K and ASME6K assembliesincludes as many CYL-0009 as specified by the model name. The number of cylinders required for either assembly shall be specified by adding to the model name as follows: ASME6K - 4. In addition, a Kunkle ASME safety relief valve, cylinder valve, and cylinder drain valve shall be provided for each cylinder.

BANK Storage Assembly

The customer may specify that an ASME5K or ASME6K storage assembly be supplied for use with a cascade fill control panel (not supplied). When specified, the assembly shall be arranged into separate BANKS of air. The number of cylinders in each BANK shall be specified by adding to the model name. Examples follow: ASME6K - 4 / BANK / 1-1-1-1 ASME6K - 6 / BANK / 2-2-1-1

Pressure gauges are not included as they are expected to be on the cascade fill control panel. The inlet /outlet are a common fitting (¼” hose connector) as there is no check valve restricting direction of air flow.

BULK Storage Assembly

If cascading is not required, the customer shall specify a BULK storage assembly requirement by adding to the model name as follows: ASME6K- 4 /BULK

BULK assemblies interconnect all required cylinders so that they act together as one larger cylinder. Each BULK assembly will be equipped with an inlet fitting, check valve, pressure gauge and outlet fitting. Any required interconnecting pigtails shall be of stainless steel tubing, not flexible hose Inlet and outlet fittings shall be ¼” hose connectors.

Required Cylinder Clamps

CMP-0027 – typically two clamps per cylinder are required.

All storage assembly components are shipped as loose items and installation, assembly, and interconnecting piping to an existing system are the responsibility of the installer, unless they are purchased factory installed in a storage rack as a complete assembly.

Required Storage Racks

RCK-0037 is a heavy duty universal two-position welded steel rack designed for use in horizontal or vertical applications. In addition, these racks can be bolted together to form multiple cylinder storage systems. Two CMP-0027 per cylinder position are included as part of the scope of supply of the RCK-0037. These racks are available as loose items or as part of a complete ASME storage assembly. Each RCK-0037 weighs approximately 130 lbs. See the following referenced outline dimensional drawings:

- ASY-0759, Vertical assemblies

- ASY-0758, Horizontal assemblies

BASIC FILL PANEL

The BFP shall provide all of the necessary components for filling two (2) SCBA or SCUBA cylinders either independently or simultaneously. All panel mounted components shall be individually labeled.

Standard Features:

− Compressor/Air Inlet fitting − Inlet pressure gauge − Adjustable pressure regulator − Regulated outlet pressure gauge − Two (2) fill control valves − One (1) pressure relief valve for regulated fill pressure − Two (2) SCBA or SCUBA fill adapters of choice complete with bleed valves (5 ft fill hoses provided unless another length is specified and supplied at additional cost).

Factory Installed Optional Accessories:

− Additional fill pressure setting (relief valve) − Up to two (2) additional fill valves, and fill whips.

− Up to four (4) bank single function cascade controls (valve and gauge for each bank)

EODTEU TWO Request
