Attachment 1 - Statement of Work 474724_Rev 1.pdf

This document is a Statement of Objectives for heaters and heater housings for an Active Cooled Beam Screen Cryo Interface, issued by Brookhaven National Laboratory on behalf of the U.S. Department of Energy.

The vendor is required to manufacture forty heaters and forty heater housings that will operate in a liquid helium environment. The heaters must be 500-Watt units at 208 Volts with a thermocouple type J temperature sensor, designed for a mass flow of 2.5 g/s at an inlet temperature of 4.7K and pressure of 3.5 Bar. Each heater will be 260mm long with an 8mm outer diameter, 57mm of cold length, and a maximum allowable pressure drop of 1.15 mbar. The heater housing will measure 258mm in length with a 12.7mm outer diameter and 8mm inner diameter, including an 18mm section on the open end with specified dimensions. The design must comply with ASME B31.3 process piping standards with a maximum allowable working pressure of 18.6 atm at 322K and minimum design metal temperature of 4K.

The vendor must provide approval drawings with ASME formatting prior to fabrication, conduct standard ASME pressure testing with documented reports, perform functional testing with temperature rise signal verification, and deliver the heaters and housings as complete assemblies. All deliverables require Finishing Certificates, Certificates of Conformance, Material Certifications, Calibration Certificates, and ISO 9001 certifications. The vendor must supply all labor, parts, tools, equipment, and necessary supplies, with all parts being new. Brookhaven National Laboratory Technical Representatives will identify issues at the time of call.
