Improvements in the Construction of Pipes for Water and other
Liquids.
I, FREDERICK MANKS, of 25, Westgate, Wakefield, in the County of York,
Plumber and Hot Water Engineer, do hereby declare the nature of this invention
to be as follows:-
The object of my invention is to line iron and other pipes for water and other
liquids with a material which will not corrode or rust, and at the same time is
strong and durable.
I line water and other pipes with thin drawn tubes or linings of aluminium or
aluminium alloy, such linings being secured within the iron tubes by either
expanding the lining or compressing the outer pipe or case, or by forcing between
the two a liquid or plastic cement or compound, which sets and fills up the space
between the aluminium lining and the metal pipe.

Improvements in the Construction of Pipes for Water and other
Liquids.
I, FREDERICK MANKS, of 25, Westgate, Wakefield, in the County of York,
Plumber and Hot Water Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
The object of my invention is to line iron and lead pipes for water and other
liquids with a material which will not corrode or rust, and at the same time is
strong and durable.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a section of a length of iron or lead pipe with aluminium or aluminium
alloy lining.
Fig. 2 is a cross section of pipe with lining before it is expanded.
Fig. 3 is a cross section of pipe with lining expanded.
I line water and other pipes A with thin drawn tubes or linings B of aluminium,
or aluminium alloy such as wolframinium or romanium, such linings being secured
within the iron tubes by expanding the lining preferably by means of heated air

Or when the outer pipe is-lead it may be compressed to the inner or aluminium
lining. The said aluminium lining strengthens the pipe as well as being non-
corrosive.
C is a taper ferrule to be driven in at each end of tube to hold the lining, in
place of turning it over at the ends.
In applying heat and pressure for expanding the inner lining, I preferably apply
heated steam or air or liquids under pressure at both ends of the pipe simultan-
eously, or an outward or inward application of heat may be applied by means of
heated mandrils or other means, whereby the aluminium or aluminium alloy is
heated up to about half its fusible temperature and pressure is simultaneously applied.
Without the combination of heat with pressure the linings are apt to split when
expanding.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I would have it under-
stood that I am aware that for the past ten years iron and other corrosive pipes havo
been lined with less corrosive pipes such as tin and copper, but what I claim is :—
1. Lining corrosive tubes or pipes with pure aluminium or aluminium alloy
substantially as described.
2. The insertion of linings of aluminium or aluminium alloy within iron, steel,
or other corrosive tubes or pipes, by means of combined heat and pressure, sub-
stantially as described.
