Click
here to download specification sheet
APPLICATION:
Corrosion resistant pressure pipe, IPS sizes 1/8” through
24”, for use at temperatures up to and including 140 °F.
Pressure rating (210 psi to 1230 psi) varies with schedule, pipe
size, and temperature 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). Typical applications include: chemical
processing, plating, high purity applications, potable water systems,
water and wastewater treatment, irrigation, agricultural, and other
industrial applications involving corrosive fluid transfer.

SCOPE:
This specification outlines minimum manufacturing requirements for
Polyvinyl Chloride (PVC) Schedule 80 iron pipe size (IPS) pressure
pipe. This pipe is intended for use in applications where the fluid
conveyed does not exceed 140°F. 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 International).
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, trade
name designation H707 PVC. This compound shall be gray in color
as specified, and shall be approved by NSF International for use
with potable water (NSF Std 61).
DIMENSIONS:
PVC Schedule 80 pipe shall be manufactured in strict accordance
to the requirements of ASTM D1785 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, flattening, and extrusion quality defined in ASTM
D1785. All belled-end pipe shall have tapered sockets to create
an interference-type fit, which meet or exceed the dimensional requirements
and the minimum socket length for pressure-type sockets as defined
in ASTM D2672. All PVC Schedule 80 pipe must also meet the requirements
of NSF Standard 14 and CSA Standard B137.3 rigid PVC pipe for pressure
applications, and shall bear the mark of these Listing agencies.
This pipe shall have a flame spread rating of 0-25 when tested for
surface burning characteristics in accordance with CAN/ULC-S102-2-M88
or equivalent.
MARKING:
Product marking shall meet the requirements of ASTM D1785 and shall
include: the manufacturer’s name (or the manufacturer’s
trademark when privately labeled); the nominal pipe size; the material
designation code; the pipe schedule and pressure rating in psi for
water @ 73°F; the ASTM designation D1785; the independent laboratory’s
seal of approval for potable water usage; and the date and time
of manufacture.
| SAMPLE SPECIFICATION:
All PVC Schedule 80 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 D1785, consistently meeting and/or
exceeding the Quality Assurance test requirements of this
standard with regard to material, workmanship, burst pressure,
flattening, 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 6” 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, INC. |

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 (WP) listed when operating at elevated
temperatures.
|
|
Multiply the working pressure rating of the selected
pipe at 73F, by the appropriate de-rating factor to determine the
maximum working pressure rating of the pipe at the elevated temperature
chosen.
EX: 10” PVC SCH 80 @ 120F = ?
230 psi x 0.40 = 92 psi max. @ 120F
THE MAXIMUM SERVICE TEMPERATURE FOR PVC IS 140F.
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 110F; use
flanged joints, unions, or roll grooved couplings where disassembly
is necessary at elevated temperatures.
|
|
Operating Temp (°F) |
De-Rating Factor |
|
|
Thread only Schedule 80 or heavier walls.
Threading requires a 50% reduction in pressure rating
stated for plain end pipe @73F. Threading of Schedule
40 PVC 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, installation data, and additional information.
