Galvanizing. Galvanizing shall be applied by the hot dipped process. The preparation for galvanizing and the galvanizing process shall not adversely affect the mechanical properties of the material being coated. The zinc coating shall be clean, of uniform thickness and free from defects. When zinc spray coating is used, surfaces shall be shot blasted before spraying. Drilling, punching, cutting, bending and removal of burrs shall be completed before galvanizing/zinc spray coating. The average thickness of the zinc coating shall be equivalent to not less than 0.6 kg/m2 of zinc for all surfaces, except steel wires. The thickness of the zinc coating for steel wires shall be in accordance with a national standard and shall be approved by the Engineer. Material on which galvanizing has been damaged shall be re-dipped unless, in the opinion of the Engineer, the damage is local and can be repaired by applying a coat of galvanizing repair paint. Where such a repair is authorized, tdamaged area shall be cleaned bwiping with clean rags saturated with mineral spirits or xylene followed by wire brushing. After wire brushing, the area shall be re-cleaned with solvent to remove residue and shall be given a minimum of two coats of zinc rich paint in accordance with the manufacturer’s instructions. Samples selected by the Engineer of all galvanized material shall be subjected to the galvanizing tests set out in the appropriate material standard (eg BS 443/BS 729). Sheradizing or other similar processes shall not be used unless expressly approved by the Engineer. Surfaces in contact with oil shall not be galvanized or cadmium plated.
Galvanizing. A. Hot-Dip Galvanized Finish: Apply zinc coating by the hot-dip process to structural steel indicated for galvanizing according to ASTM A 123. PART 3 - EXECUTION
Galvanizing. 6.12.1 Sample Tests Representative samples, selected by the Engineer of all galvanized material shall be submitted to galvanizing tests. Galvanized fittings associated with insulators, and steel cores for aluminum conductor steel reinforced cables shall be tested in line with the relevant IEC Recommendation. All other fittings, fabrications, hardware and fixings shall be inspected and tested in accordance with ISO Recommendations R1460 and R1461.
Galvanizing. .1 All materials, structural steel, pipe and fittings, including bolts, nuts and washers shall be hot dip galvanized to the requirement of CSA S37-13 and CSA-G164 and as otherwise specified therein.
Galvanizing. (a) Shop Applied
Galvanizing. A. Galvanizing of steel piling, when required, shall be by the hot dip method, in accordance with ASTM A123/A123M Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products.
Galvanizing a. Fabricate steel to be galvanized in accordance with ASTM A143, ASTM A384, and ASTM A385. Avoid fabrication techniques that could cause distortion or embrittlement of the steel.
Galvanizing. X. Xxxxxxxxxxx of steel piling, when required in the Final Design, shall be by the hot dip method, in accordance with ASTM A123/A123M Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products.
Galvanizing once machining and marking is concluded, all iron and steel parts of the accessories will be hot-dip galvanized according to the ASTM A 153 Standard. Galvanizing will have smooth, uniform, clean texture and of uniform thickness across the surface. The material preparation for galvanizing and the galvanizing process itself shall not affect the mechanical properties of the parts. The zinc coating will have a minimum thickness of 600 gr/m2 4.1.9 GROUNDING
Galvanizing. General Galvanising of iron and steel articles shall be carried out by the hot dip process. The preparation for galvanising and the galvanising process shall not adversely affect the mechanical properties of the material coated. All galvanising shall be in accordance with BS 729, ISO 1460 or an equivalent approved standard to give a uniform thickness, free from defects and a minimum average coating weight. Galvanised finned tubing shall have a minimum average thickness of 70 microns. Other methods of depositing zinc coating such as sheradising, electroplating or metal spraying shall not be used unless specifically approved. Surfaces which are in contact with fluid shall not be galvanised or cadmium plated. The identifying marks on any galvanised parts shall be stamped before galvanising is applied and shall be clearly legible afterwards. Zinc coated fasteners such as nuts and bolts should be lubricated with beeswax or other suitable lubricant prior to fitting and tightening. Material on which the galvanising has been damaged shall be re-dipped.
