Scope of Work: Building 8027 “MTF” Bulk Nitrogen System

WDTC PROJECT DRD Project 3522 “Bulk Nitrogen System MTF”

SCOPE OF WORK

For Building 8027 Material Test Facility Nitrogen Bulk Tank Pad and Nitrogen Line Installation

1. Introduction:

This Scope of Work is to install a concrete pad for a 3000 gallon liquid nitrogen tank and install stainless pipe Nitrogen Gas distribution system for Building 8027 into the three test chambers.

2. Background / History:

Building 8027 MPC, ATC and CSC chambers along with the Safety Air Monitoring room used are used to support the Next Generation Chemical Detector (NGCD) test programs and all future testing. Currently the nitrogen used to support the current test programs and safety air monitoring are being provided using 110 and 230 gallon bottles and tanks. With the upcoming installation of the new NGCD test fixtures, the amount of Nitrogen Gas exceeds our portable bottle capability. It is projected that five to six NGCD test fixtures will be operating four days a week, eight hours per day and each test fixture requires five separate Nitrogen Gas lines at various flow rates (average 100 – 150 L of Nitrogen Gas) per minute. This installation of a bulk 3000 gallon Nitrogen system with evaporator and 1” stainless steel pipes will provide the necessary Nitrogen gas without gas fluctuation or reduced flow rates and provide a safe and more cost effective way to provide nitrogen to the chamber, test fixtures and Safety Air Monitoring room.
