Their operating temperature mainly depends on the heat resistance of the FBE coating, with the core applicable temperature range and influencing factors as follows: I. Core Operating Temperature Range According to industry standards for FBE coatings (e.g., GB/T 23257-2017 Polyethylene Anticorrosive Coatings for Buried Steel Pipes, and anticorrosion requirements supporting API 5L Specification for Line Pipe), the operating temperature is divided into long-term use and short-term use: Long-term operating temperature: Generally -30℃ ~ 80℃ Within this temperature range, the FBE coating can maintain stable adhesion, impact resistance, and corrosion resistance, without cracking, peeling, or accelerated aging due to temperature changes […]https://www.wldsteel.com/wp-content/uploads/2025/09/FBE-Steel-Pipe-1.png
