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.
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.
Hydrostatic test pressures for plain-end pipe are indicated below.

Elongation in 2" Refer to A 53 Table x 4.1, latest
revision – ASTM A53/A 53M
Degree of Bend Diameter of Mandrel
Standard 90° 12 x outside pipe diameter
Close Coiling 90° 8 x outside pipe diameter
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.

Minimum wall thickness at any point shall not be more than 12.5% under nominal wall
thickness specified.
NPS 1-1/2 and under + .016"
NPS 2 and over + 1%
Pipe shall not vary more than +10% from the standard specified.
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.
