SECTION 033000 - CAST-IN-PLACE CONCRETE

Sludge Treatment Project Engineered Container Retrieval and Transfer System January 2012
E. For dissimilar welds, such as carbon or low alloy steels to austenitic stainless steels, and different
grades of stainless steel, such as 304L pipe to 316L valve the welding procedure application list
shall specify the filler material type.
F. For all filler metal, a typical test report in accordance with ASME Boiler and Pressure Vessel Section
II, Part C, is required.
G. The storage, baking, and drying of all welding consumables (i.e., covered electrodes, flux cored
electrodes, and fluxes) shall be as recommended by the manufacturer. Segregation of carbon steel,
low alloys, and alloy consumables is required during storage, baking, holding, and handling (including
portable ovens).
2.17 FASTENERS
A. Graded fasteners shall be carefully controlled as defined in the Section 014000, Quality Assurance
and Control.
B. Fasteners shall be inspected to verify compliance with the requirements listed on the design
drawings or procurement specifications.
C. Stainless-steel bolts, cap screws, and studs shall be per ASTM A193/A 193M, Grade B8 (Class 2),
and nuts shall be heavy hex nuts per ASTM A194/A 194M, Grade 8, 8S (Nitrinic 60) or 8SA
(Nitronic 60). Washers for stainless steel bolting shall be as recommended in ASME PCC-1-
2010, Appendix M. Bolts, cap screws, studs and nuts shall be grade marked.
