FLOW NOZZLE ASME PTC6

Definitive advantages result from the use of flow nozzles. For a given ratio of throat pipe to diameter, flow nozzles permits approximately 60% greater capacity than an orifice plate. TM manufacture all type of low nozzle according to ASME, ISA, UNI, DIN, B.S. etc. standards.

TECHNICAL SPECIFICATIONS
Contruction
From forged piece.
The nozzle is a curved convergent entry leading a short cylindrical throat without a discharge cone.

TYPES

High Beta Type
Inlet pressure taps located in the pipe wall at "D" preceding the plane of the nozzle elliptical inlet section, outlet pressure taps located in the pipe wall at "1/2 D" following the plane of the beginning of the elliptical inlet section of the nozzle.

Low Beta Type with or without throat taps
Inlet pressure taps located in the pipe wall at "D" preceding the plane of the nozzle elliptical inlet section, outlet pressure taps located in the pipe or on the nozzle at "1.5 d" following the entrance plane of the nozzle.

STANDARD EXECUTION

Flanged Type
Manufactured in ali sizes.
Can be supplied complete with companion flanges.

Welding -in Type with holding-ring For sizes fram 4" and up. Can be supplied completely assembled in a pro per honed flow-section. Metering flow-section is of the same material of the line and reamed over the whole lenght after the pressure taps have been fitted. The ends of flow-section can be flanged or bevelled as required. Holding ring material: same to the flow-section material

Options
Upone request f low nozzles can be supplied complete with: seal pots, stop valves, flow straightening vanes, experimental calibration test to an international apporved laboratory.
