stanger remarks, is considerably higher in Samples
1 & 3 than in the standard analysis. It appears to
me to be dangerously high, seeing that a half per
cent. is sufficient to make the metal objectionably
short.
Paras. 11, 12, 15, & 17. Apart from the apparent
shortness of the metal of Sample No. 1, it appeared
that the screw threads were out to such a depth as
to leave too little metal at the bottom of the groove.
The defects of shortness, and excessive depth
of the screw -cutting relative to thickness of metal,
were not specially pointed out when forwarding the
samples. It was thought that these defecte were self
evident, and would be held sufficient to account for
the going out of shape, and the tearing off of the
screwed end.
Whether the bending was skilfully done or not
in the particular case of Sample No. 1 must remain
a doubtful point. It is possible that it may not
have had fair play; but the failures of straight
unaltered pipes, under ordinary working conditions,
ought to be sufficient to condemn the consignment.
Samples 2 & 3 are specimens of such failures.
Para. 15. Mr. Stanger found that the joint of
Sample No. 3 was a butt welded one of poor quality,
instead of being lap welded as required by the don-
tract.
Paras. 14 & 20. Sample No. 3 was found to be
a lap welded pipe, as specified in the Contract, but with an inherent weakness at the point of fracture.
Paras. 81 & 22. A considerable difference was
found
