Why Standard Flange Choices Fail Your Operations

You source flange types for pipelines, but high prices from competitors eat into ROI. Metal flanges corrode 40% faster in harsh environments, per ASME reports.

• High Costs: Premium steel types of flanges cost 2x more than FRP alternatives.
• Low Quality: Frequent leaks cause 25% downtime in chemical plants (IndustryWeek data).
• Supply Chain Delays: Overseas metal suppliers lag 8-12 weeks vs. our 2-week high-speed delivery.
• Corrosion Risks: $2.5B annual losses in USA piping (NACE study).
• Non-Compliant Issues: Failing ASME/ANSI standards leads to regulatory fines.
