FAQ
Q1: What corrosive environments is this pipe suitable for?
A1: Especially suitable for acid/alkali environments, seawater corrosion, chemical wastewater, etc. It can resist chemical media with pH values ranging from 2-12.
Q2: What are the key installation considerations?
A2: Important notes: Maintain minimum bending radius (typically 20×pipe diameter), use dedicated connectors, avoid scratching the inner wall, and provide proper bedding for underground installation.
Q3: How to select the proper ring stiffness grade?
A3: Based on burial depth and loading: SN4 (<1m), SN8 (1-3m), SN16 (3-6m or heavy load areas). Higher grades can be customized for special conditions.
Q4: How does its maintenance cost compare to traditional pipes?
A4: Nearly maintenance-free. Unlike metal pipes requiring anti-corrosion treatment or PVC pipes prone to aging, it can reduce lifecycle costs by 40-60%.
