Lockseam Spiralweld Galvanized Pipe ®
Naylor Lockseam Spiralweld® steel pipe is manufactured in
strict accordance with ASTM A-211. The standards set forth
in this specification are closely adhered to in every phase of
production. Quality control is maintained by careful inspection
throughout. This is your assurance that Naylor pipe
equals or exceeds the ASTM specification in every respect.
Naylor Lockseam Spiralweld Pipe® is formed from strip which
is lockseamed over an internal mandrel. This process creates
an accurate tubular structure before it is welded. Thus, the
lockseam carries the load and relieves the weld of stresses
encountered when the pipe is in service. After the lockseaming
operation, the pipe is welded by completely automatic
methods which insure a weld that is as strong as the parent
metal. Every length of Naylor Lockseam Spiralweld Pipe® is
inspected and tested to the hydrostatic mill test pressures
shown in the tables on the opposite page.
Naylor Lockseam Spiralweld Pipe® provides greater overall
strength than other steel pipe of the same wall thickness--under
crushing loads, compression, collapse, and beam load at supports.
This greater strength--combined with the ability of the
lockseam spiralweld to absorb shock loads, stresses and
strains--makes it possible for Naylor Lockseam Spiralweld
Pipe® to handle jobs normally requiring heavier-wall pipe.
Naylor Lockseam Spiralweld Pipe® incorporates a safety factor
found in no other pipe. When strains are put on the line, the
“heel” of the lockseam moves minutely, shortening or lengthening
the pipe. Because the “heel” is in spiral form, it acts as
a continuous expansion joint throughout the line. It absorbs
shock loads and vibration, often destructive to a weld on a
rigid structure. It cushions expansion and contraction under
varying changes of pressure, temperature and ground stress. It
protects both pipe and coupling medium. This factor of “give”
is of major importance in pipe line construction because it
assures closer conformity to topographical conditions without
any sacrifice of strength.
Naylor Lockseam Spiralweld Pipe® is formed under tension on
a lathe-turned mandrel, which assures a perfectly-round pipe
of accurate diameter. The lockseam structure provides reinforced
strength to preserve the original true cylindrical form in
transportation, installation and service. With ends that always
match correctly and this adherence to accurate diameter,
Naylor Lockseam Spiralweld Pipe® reduces the time required to
make connections, whether mechanically coupled or welded.
UNIFORM WALL THICKNESS
Naylor pipe is manufactured from strip or sheet steel which
assures uniform wall thickness. Thickness tolerances are governed
by the standards established by the American Iron and
Naylor Lockseam Spiralweld Pipe® can be furnished in any
desired cut length up to and including 40’0”. While standard
lengths are 20’0”, 30’0” or 40’0”, the piping can be cut to any
required length, to tolerance of plus-or-minus 1/8”.
STANDARD WEIGHT ENDS
Naylor pioneered the development of lightweight pipe combined
with standard weight ends. Thus, the advantage of light
weight pipe is realized and combined with standard fittings
and equipment common to industry.
Naylor Lockseam Spiralweld Pipe® saves time, material and
money for users. Its structure permits use on jobs normally
requiring heavier-wall pipe. The relatively light weight
reduces transportation, handling and installation costs as well
as the initial investment. High salvage and re-use value are
assured by the accurate diameter and true cylindrical form
which results from the lockseam spiralweld structure.
