MBE4000 APPLICATION AND INSTALLATION
4.2.3

PIPEWORK

Give careful attention to the pipework and associated fittings used in the inlet system in order to
minimize restriction and maintain reliable sealing.
Keep piping lengths short to minimize the number of bends and restriction incurred in the system.
Use smooth bend elbows with a bend radius to tube diameter (R/D) ratio of at least 2.0 and
preferably 4.0.
Keep air ducts away from heat sources such as exhaust manifolds, etc. Use appropriate insulation
or shielding to minimize radiated heat from these sources to the inlet system.
Pipework Material Specifications
Aluminum or aluminized steel seamless tubing should be used. The tube ends require a 0.09 in.
(2.3 mm) minimum bead to retain hose and clamp connections.
Fiberglass piping between the air cleaner and the turbocharger compressor inlet is also acceptable.
DDC recommends that mitered elbows should have multiple sections for a smooth transition.

Diffusers

Make any necessary cross-sectional changes in the piping diameter gradually rather than using
sudden expansions or contractions.
