RE: Straight runs for flowmeters

The entire system has to CIP(clean in place) internally. Mechanical joints(hygienic clamps) are kept to a minimum, the only exception is for instruments that require maintenance, periodic cleaning, or calibration. Everything is modular. Piperacks are used where needed but we don't always design interconnected piping. Building contractors do most of that for our projects.

You are referring to external surface wipe-down in order to maintain surrounding room cleanliness, I assume. Do you use piperacks and modular construction for breakdown maintenance/interior cleaning, or would the mechanical joints required just add an additional possible point of ingress
for contaminants?
