Alloy 400/ UNS N04400/ NA13/ Monel 400
Cole & Swallow has developed processes for the
manufacture alloy 400 and offers quick lead
times on small quantities or in sizes not usually
held in stock. The size range may be limitied
initially but we are always ready to expand
if the market requires it. Tube up to 19.05
mm and down as small as 2 mm will be offered
in a number of wall thickness options.Alloy
400 is a widely used and specificed alloy for
corrosion resistant environments but still retains
ductility compared to high chromium alloys.
For this reason the alloy has great user friendliness
for fabricators and welders.

Bimetallic Tube Capabilities Enhanced
When complex working environments mean that
copper alloys on their own cannot provide a
heat exchange or engineering solution, it may
be possible to use a bimetallic tube. Combined
tubes can be produced with copper alloy, aluminium,
titanium, carbon or stainless steel combinations.
These give combined properties of heat exchange,
strength and corrosion resistance that single
tubes cannot provide. A special version of this
product is the high heat transfer Leak Detector
Tube which can also be offered in a number of
material combinations. This product is employed
in coolers that cannot fail without warning
- for example on critical oil coolers on pumps
or generators. The inclusion of flow galleries
between the inner and outer tube allows inner
tube failure to be discovered before full unit
failure. This allows maintenance to be done
in preventative rather than rescue mode. End
options include machining back the outer tube
to allow fitting and ferrules. Ferrules are
made in the same material as the inner tube
and are fitted to ensure the "wetted"
ends are all of one material type.

Tubing" in Product Guide.
