PART 2 - PRODUCTS
2.1 PIPES, TUBES, AND FITTINGS
A. Stainless Steel Pipe and Fittings: Schedule 10S, ASTM A 312/A 312M, Grade TP316L or
TP304L, unless otherwise indicated; seamless pipe and ASTM A 403/A 403M, Class S, seamless
fittings matching pipe thickness and grade, for welded joints.
B. Certified TP 316L or TP304L stainless steel pipe: pipe fittings, tubing and tubing fitting, plate, rod
bar, sheet and strip shall get the following tests:
1. Chemical Composition Analysis: Perform heat analysis to determine chemical composition
of material. Chemical composition: ASME: SA-312, SA-403, SA-182, SA-479,
SA-240, SA-213, SA-249 except 0.030% maximum carbon content.
2. Corrosion Testing: Test material for susceptibility to inter-granular attack per ASTM
A262 Practice A (Oxalic Acid Etch Test). Use Table 4 to screen materials. Test samples
shall be taken from representative samples from each size and heat of finished product.
Prepare specimens as required, sensitize specimens by heating for 1 h at 1250 °F + 10 o F
and quench with water. Ensure that corrosion rate for each specimen does not exceed
0.0020 in. per month for full five 48-h periods. Ensure that corrosion rate for final specimen
does not exceed corrosion rate of any of the previous specimens by more than
0.0002 in. per month.
C. Wrought Forged-Steel Flanges and Flanged Fittings: ASME B16.5, including bolts, nuts, and
gaskets of the following material group, end connections, and facings:
1. Material Group: 2.3.
2. End Connections: Weld Neck - Butt welding.
3. Facings: Raised face.
2.2 STRUCTURAL MATERIALS
A. Carbon steel shall meet the requirements of ASTM A 36/A 36M or ASTM A 992/A 992M.
B. Structural tubing shall meet the requirements of ASTM A 500/A 500M, Grade B (fy = 46 ksi).
C. Steel pipe shall meet the requirements of ASTM A 53/A 53M, black steel, Type E or S, Grade B,
or ASTM A 106/A 106M, Grade B, standard weight, Schedule 40 and Schedule 10.
D. Concrete expansion anchors shall be any industry standard wedge-type expansion anchor having
capacities published by the ICC-ES and approved for resistance to wind and seismic loading.
E. All exposed carbon steel shall be coated in accordance with Section 055000, Metal Fabrications.
Prepare, prime, and top coat structural steel in accordance with the manufacturer’s recommendations.
The final coat shall be light gray. All coatings shall be applied in such a manner as to produce
a uniform smoothness. Special attention shall be paid to crevices, weld lines, carriers, and
edges to obtain the required thickness.
