SUBMITTAL DATA

ASTM A 53 TYPE F
GRADE A PIPE


SCOPE
Covers black and hot-dipped galvanized furnace-butt welded (continuous welded) Grade A pipe. Pipe is intended for mechanical and pressure applications and is acceptable for ordinary uses in steam, water, gas and air lines. UL Listed and FM Approved Sizes 1" through 6" nominal, for use in Fire Sprinkler Pipe Applications. Pipe is suitable for welding, threading, grooving and bending. Pipe is not intended for flanging. Produced to latest revisions of ASTM A53/A 53M, Federal Specification WW-P404 and ASME B36.10M.


HOT-DIPPED GALVANIZED
The average weight of zinc coating shall be not less than 1.8 oz. per sq. ft. of surface (inside and outside). When galvanized pipe is bent or otherwise fabricated to a degree which causes zinc coating to stretch or compress beyond the limit of elasticity, some flaking of the coating may occur.

END FINISH
Plain End:
NPS 1-1/2 and smaller: unless otherwise specified on order, end finish shall be at the option of the manufacturer. NPS 2 and larger: STD and Sch 80 weights: ends beveled to angle of 0°, +50°, -0° with a root face of 1/16" + 1/32". Threaded: To ANSI Standard B 1.20.1
Couplings: To ASTM Standard A 865.

TENSILE REQUIREMENTS
Tensile Strength, min. 48 000 psi
Yield Strength, min. 30 000 psi.
Elongation in 2" Refer to A 53 Table x 4.1, latest
revision – ASTM A53/A 53M


BENDING TEST (COLD) FOR NPS 2 and UNDER:
Degree of Bend Diameter of Mandrel
Standard 90° 12 x outside pipe diameter
Close Coiling 90° 8 x outside pipe diameter


FLATTENING TEST – NPS 2-1/2 and Greater
As a test for quality of the weld, position the weld at 90° from the direction of force and flatten until the OD is 3/4 of the original outside diameter. No cracks shall occur along the inside or outside surface of the weld.

PERMISSIBLE VARIATIONS IN WALL THICKNESS
Minimum wall thickness at any point shall not be more than 12.5% under nominal wall
thickness specified.


PERMISSIBLE VARIATIONS IN OUTSIDE DIAMETER
NPS 1-1/2 and under + .016"
NPS 2 and over + 1%


PERMISSIBLE VARIATIONS IN WEIGHT PER FOOT
Pipe shall not vary more than +10% from the standard specified.


PRODUCT MARKING
Each length of pipe 1/2 NPS and larger is continuously stenciled to show the manufacturer, the grade of pipe (ASTM A 53), the kind of pipe (F for Continuous Weld, A for Grade A,) the size (Sch 80 for extra strong), and length. Stencil markings indicate UL Listing and FM Approval for sizes 1" through 6" nominal for use in Fire Sprinkler Pipe Applications. Bar Coding is acceptable as a supplementary identification method.
