D3754-24 – Standard Test Method Technical Guide
📐 Scope, Sizes, and Operating Conditions
ASTM D3754-24, the Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Sewer and Industrial Pressure Pipe, defines the requirements for machine-made composite pipes designed for demanding pressure service. This specification covers both glass-fiber-reinforced thermosetting-resin pipe (RTRP) and glass-fiber-reinforced polymer mortar pipe (RPMP). The standard applies to pipe diameters ranging from 8 in. (200 mm) through 156 in. (4000 mm) and is intended for systems operating at internal gage pressures of 450 psi (3103 kPa) or less. Typical conveyed fluids include sanitary sewage, storm water, industrial wastes, and corrosive fluids.
| 🟦 Pipe Type | 📏 Diameter Range | ⚡ Maximum Pressure | 🎯 Primary Service |
|---|---|---|---|
| RTRP / RPMP | 8 – 156 in. (200 – 4000 mm) | 450 psi (3103 kPa) | Sewage, Storm Water, Industrial Wastes, Corrosive Fluids |
⚠️ International Note: Per Note 2 of the standard, there is no known ISO equivalent to ASTM D3754. Furthermore, values stated in inch-pound units are to be regarded as the standard; SI units in parentheses are provided for information only.
⚙️ Material Performance and Verification Standards
Compliance with D3754-24 requires rigorous adherence to several companion ASTM test methods that validate structural integrity and chemical resistance. The long-term hydrostatic strength and pressure design basis must be established per ASTM D2992. For sewer and industrial environments, chemical resistance in a deflected condition is verified using ASTM D3681, while general chemical resistance of the resin follows ASTM C581. Flexible elastomeric seal joints must conform to ASTM D4161.

🚧 Installation Versatility: Buried and Trenchless Applications
While the standard is designed primarily for pipes to be installed in buried applications, its scope is specifically intended to extend to other modern installation methods. The specification explicitly covers pipes used for jacking, tunnel lining, slip-lining, and the rehabilitation of existing pipelines. This makes D3754-24 a versatile single-source standard for both conventional open-cut construction and trenchless renewal projects, provided the specific installation loads are accounted for in the design.
💡 Design Consideration: When specifying pipe under this standard for slip-lining or jacking, engineers must verify the pipe’s external loading characteristics per ASTM D2412 and its long-term structural performance against the specific jacking forces and soil loads encountered during trenchless installation.
❓ Frequently Asked Questions
🔍 What specific types of pipe does ASTM D3754-24 cover?
The standard covers machine-made “fiberglass” pipe, specifically Glass-Fiber-Reinforced Thermosetting-Resin Pipe (RTRP) and Glass-Fiber-Reinforced Polymer Mortar Pipe (RPMP), intended for pressure systems.
💡 What is the maximum size and pressure rating under this standard?
Pipe covered by this specification ranges from 8 in. (200 mm) to 156 in. (4000 mm) in diameter and is intended to operate at internal gage pressures of 450 psi (3103 kPa) or less.
⚡ Can this standard be used for trenchless applications like slip-lining?
Yes. While suited primarily for buried applications, the standard explicitly states it is acceptable to use for other installations, including jacking, tunnel lining, and slip-lining for the rehabilitation of existing pipelines.
📌 How is the long-term hydrostatic strength of the pipe validated?
The long-term hydrostatic strength and pressure design basis must be established in accordance with ASTM D2992 (Practice for Obtaining Hydrostatic or Pressure Design Basis for “Fiberglass” Pipe and Fittings).
