Thermoplastic vs. Metal Flange Spacers: When Plastic Is the Better Choice
Thermoplastic vs. Metal Flange Spacers: When Plastic Is the Better Choice Home / If you’ve been specifying metal flange spacers for your piping systems, it may be worth reconsidering. In corrosive, chemical, and industrial fluid handling applications, thermoplastic flange spacers consistently outperform metal in the areas that matter most — chemical resistance, weight, cost, and […]
Flange Spacer Types Explained: Which One Does Your Lined Pipe System Need?
Not all flange spacers are created equal — and choosing the wrong type for your lined pipe system can result in poor fit, compromised sealing, or an inability to meet your process requirements. SG&P manufactures 11 distinct types of thermoplastic flange spacers, each designed for a specific application or configuration.
PVDF vs PTFE vs Polypropylene: Which Material for Your Flange Spacer?
PVDF, PTFE, and Polypropylene each offer distinct advantages for thermoplastic flange spacer applications. This material selection guide compares chemical resistance, temperature ratings, mechanical strength, creep resistance, and cost — helping process engineers specify the right material for lined pipe systems in chemical, water treatment, and industrial service.
Chemical Resistance Guide: Plastic Flange Spacers in Corrosive Environments
Selecting the right thermoplastic flange spacer for corrosive service starts with understanding chemical compatibility. This guide compares PVDF, PTFE, and Polypropylene across common industrial chemicals — including hydrochloric acid, chlorine, caustic soda, and steam — with a quick-reference chart and step-by-step material selection framework.
