ASME RTP-1-2023 PDF

Full title and description

ASME RTP-1:2023 — Reinforced Thermoset Plastic Corrosion-Resistant Equipment. This American National Standard contains rules, design requirements, fabrication and inspection provisions, and testing guidance for stationary reinforced thermoset plastic (RTP) corrosion‑resistant vessels used for storage, accumulation, or processing of corrosive or other substances at pressures within the RTP limits specified by the standard.

Abstract

This standard establishes minimum requirements for materials, design, fabrication, quality control, inspection, testing, and in‑service considerations for reinforced thermoset plastic corrosion‑resistant equipment (RTP). It adapts applicable principles from metallic pressure‑vessel practice where appropriate and addresses RTP‑specific behaviors and limitations to ensure safe, reliable performance of RTP vessels and related equipment.

Scope

RTP‑1 applies to stationary reinforced thermoset plastic corrosion‑resistant vessels intended for storage, accumulation, or processing of corrosive or other substances where operating pressures do not exceed the RTP limits (typically not exceeding 15 psig external and/or 15 psig internal above any hydrostatic head). The standard provides requirements for materials of construction, design evaluation, fabrication practices, quality control, inspection, and testing applicable to RTP vessels and certain related assemblies, and includes provisions (and appendices) addressing dual‑laminate constructions and other RTP configurations.

Key topics and requirements

• Definitions and material properties specific to reinforced thermoset plastics and laminates.
• Design rules and stress analysis methods adapted for RTP behavior (including allowable stresses and factors of safety).
• Fabrication requirements: layup, cure, bonding, and joining practices for RTP vessels.
• Quality control and inspection: NDE methods, visual inspection, dimensional checks, and acceptance criteria.
• Hydrostatic and pneumatic testing procedures and leak‑testing guidance.
• Special provisions for dual‑laminate (FRP/thermoplastic lining) vessels and mandatory appendices addressing those constructions.
• Marking, documentation, and manufacturer’s data report requirements for completed equipment.

Typical use and users

Used by design and mechanical engineers, fabricators, inspection and QA/QC personnel, plant operators, procurement specialists, and regulators in chemical processing, water and wastewater treatment, mining, electroplating, and other industries handling corrosive fluids. Typical applications include storage tanks, process vessels, scrubbers, and lined/dual‑laminate vessels where corrosion resistance and low to moderate pressure containment are required.

Related standards

Commonly referenced alongside other ASME publications and industry documents such as ASME Section X (fiber‑reinforced pressure vessels), ASME B31.3 (process piping) where piping interfaces are involved, and material/test standards or ASTM methods relevant to plastics and composites. RTP‑1 includes appendices and references to complementary guidance for dual‑laminate systems and inspection practices.
