1.4.2

High Pressure Compressed Air System

Show location, length, and type of welds or brazes, and indicate welding

and brazing procedures to be used, preheat, postweld heat treatment, and

nondestructive welding and brazing testing required.

1.4.3

Laboratory Test Reports and Material Control

Laboratory Test Reports and Material Control for high Pressure Compressed

Air Systems:

1.4.3.1

Laboratory Test Reports

Furnish the following laboratory test reports for pipe, tube, fittings,

valves, and other pressure containing components (except pressure gages)

for each heat and lot of material.

a.

Full chemical analyses.

b.

Physical properties.

c.

Etch test per ASTM E 381 as modified for the alloy to verify pipe

and tube are seamless and free of defects.

1.4.3.2

Material Control

Where more than one type of corrosion resistant alloy (stainless steel and

copper-nickel or nickel-copper for example) is to be installed at project

site, the Contractor shall implement and maintain a material control system

with markings and/or tags to identify positively each piece as to the type

of metal.
