The Fu-Mech double flanged pipe (model FU-DFP) is fabricated to order to complete tank, pump-room and civil pipework packages. This guide covers where it is used, the critical point in selecting and installing it, and how to order.
At a glance
- A flange on each end.
- Made to the length on the drawing.
- Flanges drilled to ANSI B16.5 or PN16 to order.
- Easy to fit and remove for maintenance.
What is it?
A straight pipe spool with a flange on each end, made to the length you need to connect valves, fittings and equipment in pump rooms and valve chambers.
Where it is used
- Pump-room and valve-chamber pipework.
- Connections between valves and fittings.
- Replacement spools in existing systems.
Length and bolt holes
Length is measured face to face. If the spool connects two items already in place, the bolt holes at both ends must line up with them — state this with your order or send the drawing.
Caution
Check sizes, flange standard and lengths against the approved piping drawing before fabrication; made-to-order items are built to the data you send.

Frequently asked questions
How do I measure the length?
Face to face of the flanges, deducting gasket thickness if the measurement is taken between items already installed.
Which flange standards are available?
Flanges are drilled to ASME B16.5 Class 150 or EN 1092-1 PN16, to match the valves and equipment on your project.
Do you make non-standard items?
Yes. We fabricate non-standard sizes, lengths and end connections to the project drawing. Send the drawing and we send a quotation.
What should I send for a quotation?
Model code FU-DFP, Size (DN), Flange standard: ANSI B16.5 or PN16, Face-to-face length (mm), Quantity, and the drawing if the item is non-standard.
