Warwick Hanger 1551-3 Pipe Insulation Shield 3 Inch 25 Pack

Product Description

The WARWICK HANGER 1551-3 is a galvanized carbon steel pipe insulation shield designed to protect pipe insulation at hanger support points. With a 3-inch pipe size rating, a 3.5-inch inner diameter, and a 10-inch shield length fabricated from 18-gauge carbon steel with a galvanized plated finish, this shield prevents compression and damage to insulation materials where pipe hangers make contact. Plumbers, pipefitters, and mechanical contractors install these shields as a standard part of insulated piping assemblies in both commercial and residential mechanical systems.

This shield is suited for use on 3-inch insulated pipe runs in HVAC, plumbing, and process piping applications. It is compatible with foam, fiberglass, and high-density insulation types commonly found on chilled water, hot water, refrigerant, and domestic water piping systems. The galvanized finish provides corrosion resistance in typical mechanical room and indoor piping environments. Shields are sold in a packaging quantity of 25, making them practical for new construction and retrofit piping projects where multiple hanger points require insulation protection.

Key Features

• Protects foam, fiberglass, and high-density pipe insulation at hanger contact points
• 18-gauge carbon steel construction provides rigid support without crushing insulation
• Galvanized plated finish for corrosion resistance in indoor mechanical environments
• 3.5-inch inner diameter sized for 3-inch pipe with insulation wrap in place
• 10-inch shield length distributes hanger load over a wider surface area
• Packaged in quantities of 25 for multi-point piping installations

Compatibility

Designed for use with 3-inch pipe and standard pipe hangers on insulated piping systems. Compatible with foam, fiberglass, or high-density insulation materials. Intended for use as an insulation protection shield at hanger support locations in mechanical piping assemblies.

Installation Notes

Insulation shields are installed by licensed plumbers, pipefitters, or mechanical contractors as part of supported insulated piping systems. Wrap the insulation shield around the pipe insulation at each hanger location before securing the hanger to ensure the insulation is not compressed or damaged by the hanger rod load. Follow applicable mechanical and plumbing codes, including IPC and SMACNA guidelines, for hanger spacing and insulation protection requirements. Always depressurize and isolate the piping system before performing any work on existing pipe runs.
