Testing and delivery

The purchase specification should identify inspection points, pressure or leak testing, electrical checks, instrument calibration, factory acceptance testing, packing, preservation, shipping documents and the information required for site installation.

What to include in an RFQ

Include gas composition, flow cases, pressure and temperature, equipment location, hazardous-area classification, design standards, utilities, battery limits, delivery location, documentation requirements, inspection requirements and target schedule.

The words “complete system” are not enough for a technical quotation. The RFQ should list what the vendor supplies, what the site supplies and where each interface stops.
