to download specification sheet
APPLICATION:
Corrosion resistant pressure pipe, IPS sizes 3/4" through 24",
for use at temperatures up to and including 140 F. Pressure rating
(100 psi to 200 psi) varies with SDR Series and temperature shown
on page 2 of this specification, and as stated in Harvel Plastics,
Inc. engineering bulletin (Product Bulletin 112/401). Generally
resistant to most acids, bases, salts, aliphatic solutions, oxidants,
and halogens. Chemical resistance data is available and should be
referenced for proper material selection. Pipe exhibits excellent
physical properties and flammability characteristics (independently
tested flame and smoke characteristics-ULC,1993). Typical applications
include: potable water systems, water and wastewater treatment,
irrigation, agricultural, high purity applications, chemical processing,
and other industrial applications involving corrosive fluid transfer.

SCOPE:
This specification outlines minimum manufacturing requirements for
Polyvinyl Chloride (PVC) SDR Series iron pipe size (IPS) pressure
pipe. This pipe is intended for use in piping systems where the
fluid conveyed does not exceed 140F. This pipe meets and or exceeds
the industry standards and requirements as set forth by the American
Society for Testing and Materials (ASTM) and the National Sanitation
Foundation (NSF).
PVC MATERIALS:
The material used in the manufacture of the pipe shall be domestically
produced rigid polyvinyl chloride (PVC) compound, Type I Grade I,
with a Cell Classification of 12454 as defined in ASTM D1784, tradename
designation H707 PVC. This compound shall be white or gray in color
as specified, and shall be approved by NSF for use with potable
water.
DIMENSIONS:
PVC SDR Series pipe shall be manufactured in strict accordance to
the requirements of ASTM D2241 for physical dimensions and tolerances.
Each production run of pipe manufactured in compliance to this standard,
shall also meet or exceed the test requirements for materials, workmanship,
burst pressure, impact resistance, flattening, and extrusion quality
as defined in ASTM D2241. This pipe shall be produced in IPS diameters
to either: SDR 21 (3/4"–8" sizes 200 psi @ 73F);
SDR 26 (1"–24" sizes 160 psi @ 73F); or SDR 41 (18"–24"
100 psi @ 73F) as specified. All belled end pipe shall have tapered
sockets to create an interference type fit, which shall meet or
exceed dimensional requirements and the minimum socket length for
pressure-type belled sockets as defined in ASTM D2672.
MARKING:
Product marking shall meet the requirements of ASTM D2241 and shall
include: the manufacturers name (or the manufacturers trademark
when privately labeled); the nominal pipe size; the outside diameter
system; the material designation code; the applicable Standard thermoplastic
pipe Dimension Ratio designation code (SDR number) and the corresponding
pressure rating in psi for water @ 73F; the ASTM designation D2241;
and the independent laboratory’s’ seal of approval for
potable water usage.
| SAMPLE SPECIFICATION:
All PVC SDR Series pipe shall be manufactured from a Type
I, Grade I Polyvinyl Chloride (PVC) compound with a Cell Classification
of 12454 per ASTM D1784. The pipe shall be manufactured in
strict compliance to ASTM D2241, consistently meeting and/or
exceeding the Quality Assurance test requirements of this
standard with regard to pressure rating, material, workmanship,
burst pressure, flattening, impact resistance, and extrusion
quality. The pipe shall be manufactured in the USA, using
domestic materials, by an ISO 9001 certified manufacturer.
Standard lengths of pipe sizes 10" and larger shall be
beveled each end by the pipe manufacturer. All pipe shall
be stored indoors after production at the manufacturing site
until shipped from factory. This pipe shall carry the National
Sanitation Foundation (NSF) seal of approval for potable water
applications. All pipe shall be manufactured by HARVEL PLASTICS,

ASTM STANDARD D1784 MATERIAL EQUIVALENTS:
Cell Classification12454 = PVC Type I Grade I = PVC 1120
PIPE SIZES SHOWN ARE MANUFACTURED IN STRICT COMPLIANCE WITH ASTM
D1785
The pressure ratings given are for water, non-shock, @ 73°F.
The following temperature de-rating factors are to be applied to
the working pressure ratings (W.P.) listed when operating at elevated
temperatures. Multiply the working pressure rating of the selected
pipe at 73°F, by the appropriate de-rating factor to determine
the maximum working pressure rating of the pipe at the elevated
temperature chosen. |

EX: SDR 21 @ 120°F = ?
200 psi x 0.40 = 80 psi max. @ 120°F
THE MAXIMUM SERVICE TEMPERATURE FOR PVC IS 140°F.
Solvent cemented joints should be utilized when working at or near
maximum temperatures. Harvel Plastics does not recommend the use
of PVC for threaded connections at temperatures above 110°F;
use flanged joints, unions, or roll grooved couplings where disassembly
is necessary at elevated temperatures.
Threading of SDR Series pipe is not a recommended practice due to
insufficient wall thickness.
Chemical resistance data should be referenced for proper material
selection and possible de-rating when working with fluids other
than water. Refer to Harvel Plastics 112/401 Product Bulletin for
chemical resistance and installation data.
