Centrifugal compressor symbol

Also called Compressor

A centrifugal compressor raises the pressure of a gas with high-speed impellers. It handles large gas flows continuously.

What the centrifugal compressor symbol means

A centrifugal compressor raises the pressure of a gas with high-speed impellers. It handles large gas flows continuously.

How it is drawn

A circle with two lines converging from the inlet side to the outlet side, showing the gas being squeezed.

Variants

  • Trapezoid outline without the circle

US legend (PIP PIC001)

Drawn as on most US-style legend sheets.

ISO 10628-2X8179

Compressor, centrifugal type. The ISO compressor is a circle with two lines narrowing towards the outlet, without meeting. The centrifugal type adds a line through the middle. The general compressor is 2302.

ISO SVG

German (DIN): Turboverdichter. See DIN P&ID symbols.

Where you see it on a P&ID

On gas compression, export, refrigeration and recycle gas services.

Tag codes

The centrifugal compressor is commonly tagged:

  • K
  • C

Tag formats follow the project numbering procedure. For instruments, the letters follow ISA 5.1, explained on the instrument symbols page.

Frequently asked questions

What does the centrifugal compressor symbol look like on a P&ID?

A circle with two lines converging from the inlet side to the outlet side, showing the gas being squeezed.

What is a centrifugal compressor used for?

A centrifugal compressor raises the pressure of a gas with high-speed impellers. It handles large gas flows continuously. You will find it on gas compression, export, refrigeration and recycle gas services.

What tag does a centrifugal compressor have?

It is commonly tagged K, C. The exact tag format comes from the project numbering procedure and the legend sheets.

Is the centrifugal compressor symbol the same in ISA and ISO?

No. The ISO compressor is a circle with two lines narrowing towards the outlet, without meeting. The centrifugal type adds a line through the middle. The general compressor is 2302. The ISO 10628-2 registration number is X8179. Always check the legend sheets at the front of the P&ID set.

What is the centrifugal compressor called in German?

Turboverdichter. On a German R&I-Fließschema it is drawn to DIN EN ISO 10628-2.
