Double Branch Instrument Tees

Double branch instrument tees or instrument crosses as they are also know as, are a great way of introducing two instruments into a pipeline or allow mixing of process fluids within a very confined space envelope.

Our standard double branch tee has the branches set at 180 degrees, however we can supply them with branches perpendicular to each other too upon request.

The centreline to face dimension of the branch is to ASME B16.5 for the nominal bore of the body but the body face to face is determined by the diameter of the branch nominal bore. The body diameter is sized to fit neatly inside the inner bolt circle of the mating flanges.

The dimensions below are to suit ASME B16.5 flanges.
