Design Features

Design Characteristics

  • drawing of sample proportional to flow rate or in time intervals
  • manual or automatic operation
  • pressure free sampling
  • defined sample quantity
  • sampling container customized
  • operation simple and safe

The isokinetic AZ sampling system type „SIC“ consists of a multiple pipe for two-phase liquids. It applies to oil platforms and in plants e.g. for the production of petroleum.

Function:
The small pipes, which are arranged in the diameter of the main line, against the flow, lead a cross section of the main product stream isokinetic over a bypass to the sampling system. Thus develops a representative sample of the two-phase liquid. There is no need of an additional mixer or a centrifugal device! The sampling frequency can be directed by an optional control unit proportional to the flow rate or in time intervals.

Operating temperatures < -30°C and > 220 °C have to be checked and approved by AZ according to the operating conditions.

Besides the P/T value of the sleeve the limitations of the valve bodies also have to be considered. Please refer to the EN 12516-1 resp. ASME B16.34 in order to choose a proper pressure rating (PN/class). The shown values refer to austenitic stainless steel 1.4408 (A351 Gr. CF8M).

1) For operating temperatures below -10°C low temperature / austenitic steels are required.
2) Sleeve: There are different sleeve materials / compounds available.
