Grooved Flange Pipe Fitting

Grooved Flange Pipe Fitting

Product Overview

The Grooved Flange Pipe Fitting is a specialized hybrid component designed to bridge the gap between grooved piping systems and flanged equipment. This fitting features a grooved end for rapid mechanical connection to a pipe and a standard drilled flange face for bolting to pumps, valves, or other flanged components. Manufactured from high-strength ductile iron or steel, it serves as a critical transition point in industrial and fire protection pipelines, allowing for the integration of modern grooved piping with traditional flanged infrastructure without the need for welding.

Key Features and Benefits

• Hybrid Connectivity: Seamlessly connects grooved piping to flanged equipment (pumps, tanks, valves), eliminating the need for welding or threading adapters on-site.

• Rapid Installation: The grooved end allows for quick assembly using standard couplings, significantly reducing labor time compared to welding a flange to a pipe.

• Vibration Isolation: When installed with a flexible grooved coupling, the fitting helps dampen vibration from connected machinery, protecting the flanged equipment from stress.

• High Pressure Integrity: Engineered to withstand high working pressures (typically up to 300 PSI or higher), ensuring safety in critical fire protection and industrial water systems.

• Versatile Facing: Available with Flat Face (FF) or Raised Face (RF) flange configurations to match various equipment standards (ANSI, DIN, JIS).
