ASTM F2207-06(2023)

Anotace textu normy ASTM F2207-06(2023) :

This specification covers the requirements and test procedures for materials, dimensions, hydrostatic burst strength, chemical resistance, peeling strength, adhesion strength, and tensile strength properties for cured-in-place (CIP) pipe liners installed into existing metallic gas pipes for rehabilitation purposes. These cured-in-place pipe liners are intended for use in pipelines that transport natural gas, petroleum fuels (propane-air and propanebutane vapor mixtures), and manufactured and mixed gases, where resistance to gas permeation, ground movement, internal corrosion, leaking joints, pinholes, and chemical attack are required. The materials, which shall be considered separately for testing, consist of the flexible tubing, jacket, elastomer skin, and adhesive system.
