Overview

ASTM D3517-19 is the standard specification developed by ASTM International for machine-made fiberglass (glass-fiber-reinforced thermosetting-resin or polymer mortar) pressure pipes. Designed primarily for water conveyance systems, these pipes are engineered to perform in buried applications and may also be used for installations such as jacking, tunnel lining, and slip-lining for pipeline rehabilitation. Covering pipes ranging from 8 inches (200 mm) to 156 inches (4000 mm) in diameter, the specification addresses requirements for pipes operating at internal pressures up to 450 psi (3103 kPa).

Fiberglass pressure pipes under this standard are constructed using thermosetting resins (polyester, epoxy, or vinyl ester), glass fiber reinforcement, and, where applicable, siliceous sand or aggregate fillers. ASTM D3517-19 details the designation requirements for pipe types, liners, grades, classes, and stiffness, as well as performance criteria for hydrostatic strength, stiffness, joint tightness, and longitudinal strength.

Key Topics

• Material Composition: Defines allowable materials, including thermosetting resins, E-type glass fiber reinforcement, fillers, and aggregates.
• Pipe Types: Includes both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP).
• Size and Pressure Ranges: Specifies diameters from 8 in. (200 mm) to 156 in. (4000 mm), with maximum internal pressure of 450 psi (3103 kPa).
• Liners and Surface Layers: Permits inclusion of reinforced or non-reinforced thermoset or thermoplastic liners, and exterior surface layers as needed.
• Joint Types: Covers both unrestrained and restrained joints, including bell-and-spigot, mechanical coupling, flanged, adhesive-bonded, and threaded joints.
• Performance Testing: Outlines requirements and methods for testing pipe hydrostatic strength, pipe stiffness, hoop-tensile strength, joint tightness, soundness, and longitudinal strength (tensile and compression).
• Dimensions and Tolerances: Establishes standards for inside and outside diameters, wall thickness, length, squareness of pipe ends, and uniformity.

Applications

• Water Conveyance: Primarily used for conveying potable and non-potable water in municipal, industrial, and agricultural systems.
• Buried Installations: Fiberglass pressure pipes are well suited for underground pipe installations due to their corrosion resistance and structural performance.
• Pipeline Rehabilitation: Used in slip-lining and tunnel-lining methods to rehabilitate aging or damaged pipelines without excavation.
• Other Infrastructure: Can be applied in installations requiring high strength-to-weight ratio and resistance to internal pressure, such as jacking or trenchless construction methods.

Compliance with NSF Standard 61 is required for potable water applications, ensuring chemical safety and performance. Joint integrity, pressure capacity, and stiffness are critical for ensuring system safety, longevity, and reliability.

3.2.8 surface layer—a resin layer, with or without filler, or reinforcements, or both, applied to the exterior surface of the pipe
structural wall.
4. Classification
4.1 General—This specification covers fiberglass pressure pipe defined by raw materials in the structural wall (type) and liner,
surface layer material (grade), operating pressure (class), and pipe stiffness. Table 1 lists the types, liners, grades, classes, and
stiffnesses that are covered.
NOTE 3—All possible combinations of types, liners, grades, classes, and stiffnesses may not be commercially available. Additional types, liners, grades,
and stiffnesses may be added as they become commercially available. The purchaser should determine for himself or consult with the manufacturer for
the proper class, type, liner, grade and stiffness of pipe to be used under the installation and operating conditions that will exist for the project in which
the pipe is to be used.
4.2 Designation Requirements—The pipe materials designation code shall consist of the standard designation, ASTM D3517,
followed by type, liner, and grade in Arabic numerals, class by the letter C and two or three Arabic numerals, and pipe stiffness
by a capital letter. Table 1 presents a summary of the designation requirements. Thus, a complete material code shall consist of
ASTM D3517. . . three numerals, C . . . and two or three numerals, and a capital letter.
NOTE 4—Examples of the designation are as follows: (1) ASTM D3517-1-1-3-C50-A for glass-fiber reinforced aggregate and polyester resin mortar
pipe with a reinforced thermoset liner and an unreinforced polyester resin and sand surface layer, for operation at 50 psi (345 kPa), and having a minimum
pipe stiffness of 9 psi (62 kPa), (2) ASTM D3517-4-2-6-C200-C for glass-fiber reinforced epoxy resin pipe with a non-reinforced thermoset liner, no
surface layer, for operation at 200 psi (1380 kPa), and having a minimum pipe stiffness of 36 psi (248 kPa).
NOTE 5—Although the “Form and Style for ASTM Standards” manual requires that the type classification be roman numerals, it is recognized that
companies have stencil cutting equipment for this style of type, and it is therefore acceptable to mark the product type in arabic numbers.
5. Materials and Manufacture
5.1 General—The thermosetting resins, glass fiber reinforcements, fillers, and other materials, when combined as a composite
structure, shall produce piping products that meet the performance requirements of this specification.
5.2 Wall Composition—The basic structural wall composition shall consist of thermosetting resin, glass fiber reinforcement, and,
if used, an aggregate filler.
5.2.1 Resin—A thermosetting polyester or epoxy resin, with or without filler.
5.2.2 Reinforcement—A commercial grade of glass fibers compatible with the resin used.
5.2.3 Aggregate—A siliceous sand conforming to the requirements of Specification C33C33/C33M, except that the require-
ments for gradation shall not apply.

6.3 Soundness—Unless otherwise agreed upon between purchaser and supplier, test each length of pipe up to 96 in. (2400 mm)
diameter hydrostatically without leakage or cracking, at the internal hydrostatic proof pressures specified for the applicable class
in Table 4, when tested in accordance with 8.2. For sizes over 96 in. (2400 mm), the frequency of hydrostatic leak tests shall be
as agreed upon by purchaser and supplier.
6.4 Hydrostatic Design Basis:
6.4.1 Long-Term Hydrostatic Pressure—The pressure classes shall be based on long-term hydrostatic pressure data obtained in
accordance with 8.3 and categorized in accordance with Table 5. Pressure classes are based on extrapolated strengths at 50 years.
For pipe subjected to longitudinal loads or circumferential bending, the effect of these conditions on the hydrostatic design
pressure, classification of the pipe must be considered.

6.4.2 Control Requirements—Test pipe specimens periodically in accordance with Practice D2992.
NOTE 9—Hydrostatic design basis (HDB-extrapolated value at 50 years) determined in accordance with Procedure A of Practice D2992, may be
substituted for the Procedure B evaluation required by 8.3. It is generally accepted that the Procedure A HDB value times 3 is equivalent to the Procedure
B HDB value.
6.5 Stiffness—Each length of pipe shall have sufficient strength to exhibit the minimum pipe stiffness (F/Δy) specified in Table
6, when tested in accordance with 8.4. At deflection level A per Table 7, there shall be no visible damage in the test specimen
evidenced by surface cracks. At deflection level B per Table 7, there shall be no indication of structural damage as evidenced by
interlaminar separation, separation of the liner or surface layer (if incorporated) from the structural wall, tensile failure of the glass
fiber reinforcement, and fracture or buckling of the pipe wall.
NOTE 10—This is a visual observation (made with the unaided eye) for quality control purposes only and should not be considered a simulated service
test. Table 7 values are based on an in-use long-term deflection limit of 5 % and provide an appropriate uniform safety margin for all pipe stiffnesses.
Since the pipe stiffness values (F/Δy) shown in Table 6 vary, the percent deflection of the pipe under a given set of installation conditions will not be
constant for all pipes. To avoid possible misapplication, take care to analyze all conditions which might affect performance of the installed pipe.
6.5.1 For other pipe stiffness levels, appropriate values for Level A and Level B deflections (Table 7) may be computed as
follows:
0.33
Level A at new PS 5 9 (1)
S D ~ !
new PS
Level B at new PS 5 new Level A÷0.6
6.5.2 Since products may have use limits of other than 5 % long-term deflection, Level A and Level B deflections (Table 7) may
be proportionally adjusted to maintain equivalent in-use safety margins. For example, a 4 % long-term limiting deflection would
result in a 20 % reduction of Level A and Level B deflections, while a 6 % limiting deflection would result in a 20 % increase in

Level A and Level B deflection values. However, minimum values for Level A and Level B deflections shall be equivalent to strains
of 0.6 and 1.0 % respectively (as computed by Eq X1.4 in Appendix X1 of Specification D3262).
6.5.3 For high stiffness pipes, 5 % deflection will likely be above the use limit and the adjusted level A test deflection. For very
high stiffness pipes, 5 % deflection may also be greater than the adjusted level B test deflection. In such cases, the pipes may be
damaged or fail prior to determining the pipe stiffness at 5 % deflection. Therefore, it is permitted to set the pipe stiffness test
deflection equal to the adjusted level A deflection, but not greater than 5 %. See Note 11 for additional information and further
clarification.
NOTE 11—Depending upon the product modulus and allowable ring bending strain, this will likely begin affecting pipes with stiffness between 200
and 400 psi. For example, a pipe with pipe stiffness of PS360 may have a use limit of 4.3 %, an adjusted level A deflection of 4.5 % and an adjusted
level B deflection of 7.5 %. Therefore, the new pipe stiffness test deflection would be 4.5 %. Another possible product with a pipe stiffness of PS900 may
have a use limit of 2.8 %, an adjusted level A deflection of 2.7 % and an adjusted level B deflection of 4.5%. Therefore, the new pipe stiffness test
deflection would be 2.7 %.
6.6 Hoop-Tensile Strength—All pipe manufactured under this specification shall meet or exceed the hoop-tensile strength shown
for each size and class in Table 8, when tested in accordance with 8.5.
6.6.1 Alternative Requirements—When agreed upon between the purchaser and the supplier, the minimum hoop-tensile strength
shall be as determined in accordance with 8.5.1.
6.7 Joint Tightness—All joints shall meet the laboratory performance requirements, of Specification D4161. Unrestrained joints
shall be tested with a fixed end closure condition and restrained joints shall be tested with a free end closure condition. Rigid joints
shall be exempt from angular deflection requirements of D4161. Rigid joints typically include butt joints with laminated overlay,
bell-and-spigot joints with laminated overlay, flanged, bell-and-spigot adhesive bonded and threaded.
6.8 Longitudinal Strength:
6.8.1 Beam Strength—For pipe sizes up to 27 in. the pipe shall withstand, without failure, the beam loads specified in Table 9,
