edges of heads, of properly heated ana tissu
rivets shall be free from checks or cracks. Al
steel rivets not conforming to the above rs-
q~uirements will be rejected. ~
All riveting in Che shop must be done with
hot steel rivets by steam, compressed az %
and retaining it sufficiently to perfectly form
the rivet heads before the metal loses ~ -
color.
All rivets when driven must fit the noies
completely. and have heads of such torli aid
size as will be directed by the Engineer. a.
Care must be taken 10 have the risets e.
the right heat to produce the best and most
solid work, and any rivet that may az any LINZ I'm

been overheated, shall be cut out and rsplaceu
at the contractors expense by one wnicn -

In cases of accidental rusting the rust must
be removed from the plates before proceeoihs
with the manufacture of the pipe.
Where angles or curves occur In the al,gnt
n1ent and grade Of the conduit, the plates mus.
be cut and punched to the required lines ior
forming a slight oblique angle at the clrcuias

Openings for man-holes, blow-offs, air valves,
etc, will be cut and rivet holes punched in tins

During the manufacture of the pipe sample
lengths, to be seles Ted by the Engineer as ire
quently as he may deem necessary, shall pt

inch, and shall be absolutely tight under tina
pressure. If tested before the coating IS ap
piled the pipe must be thoroughly oiled witt
The pipe when laid shall also be tested un
der a pressure of so per cent. greater than tina
to which it will be subjected in normal oper
alton, and shall be absolutely tight under tina
pressure. All such tests shall be made at TN
expense of the Contractor. and ne shall furhlsl
