PVC PIPE - SCHEDULE 120
Click
here to download specification sheet
APPLICATION:
High pressure corrosion resistant, IPS sizes 1/2" through 8",
for use at temperatures up to and including 140°F. Pressure
rating (380 psi to 1010 psi) varies with 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,
and other industrial applications involving corrosive fluid transfer
where high pressures are encountered. Schedule 120 heavy wall dimensions
provide sufficient wall thickness suitable for many drilling, tapping,
and other custom machining/fabrication operations.

SCOPE:
This specification outlines minimum manufacturing requirements for
Polyvinyl Chloride (PVC) schedule 120 iron pipe size (IPS) pressure
pipe. This pipe is intended for use in industrial systems 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 NSF
International (NSF Std. 61 and NSF Std 14).
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. This
compound shall be gray in color, and shall be approved by the NSF
International (NSF) for use with potable water.
DIMENSIONS:
PVC Schedule 120 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.
MARKING:
Product marking shall meet the requirements of ASTM D1785 and shall
include: the manufacturers name (or the manufacturers trademark
when privately labeled); the nominal pipe size; the PVC 1120 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 (NSF-pw), and the date
of manufacture.
| SAMPLE SPECIFICATION:
All PVC Schedule 120 pipe shall be manufactured from a Type
I, Grade I Polyvinyl Chloride (PVC) compound with a Cell Classification
of 12454 per ASTM D1784, trade name H707 PVC. 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. 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. |

ASTM STANDARD D1784 MATERIAL EQUIVALENTS:
Cell Classification 12454 = PVC Type I Grade I = PVC1120
PIPE SIZES SHOWN ARE MANUFACTURED IN STRICT COMPLIANCE WITH ASTM
D1785
The working pressure ratings (W.P.) 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.
|
| Operating Temp (°F) |
De-Rating Factor |
|
|
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: 6" PVC SCH 120 @ 130°F = ?
370 psi x 0.31 = 115 psi max. @ 130°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 requires a 50% reduction in pressure rating stated for
plain end pipe @73°F.
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.
Reference Harvel Plastics, Inc Product Bulletin 112/401 for information
pertaining to chemical resistance, physical properties, joining
methods, hangers and supports, collapse pressure ratings, system
components and other system design and installation related data.
