ANNEXURE A : TECHNICAL SPECIFICATION AND BOM

General Overview:

The gas distribution system will cater gas supply demands to two similar type reactor. The P&I diagram is prepared

on the basis of process demand. The distribution system consists of needle valves, rotameters, control valves

pressure gages, flow transmitter and pressure transmitter with necessary piping. All of the equipments need to be

housed within a containment (termed as panel) of 1500(width) x1700(height) x700 (depth) mm. The Panel has

three inlets gas lines including compressed air. The internal piping and controlling arrangement allows gases to

divert into desired furnaces at specified flowrate. The Gas distribution panel is covered from all sides with

openable MS powder coated CRCA sheet. The details description of the distribution panel is given in specification

below. A draft schematic of panel frontend and P&I diagram is attached for reference. All instruments, Control

Valve are flanged end and necessary reducer, expander, adapter etc are to be fitted as per requirement.

The space mentioned as ‘Future Expansion’ should be kept black and the cut-outs should be covered.

Scope of works:

1. Preparation of GA drawing, Isometric drawing as per P&I diagram of the gas distribution system provided

by the customer based on process data

2. Forward drawings, deign calculation and specification for approval.

3. Fabrication of the complete system.
