Engineered for Precision in Heat-Affected Zone Repairs
At Hunt Pipeline Products, we manufacture high-quality Weld Support Sleeves designed specifically for integrity repairs in the heat-affected zone (HAZ) of pipelines. These sleeves are engineered with a built-in clearance that allows them to pass over a girth weld without interfering with the pipeline’s structural integrity — making them ideal for reinforcing welded areas while maintaining code compliance.
Our Weld Support Sleeves are available in sizes ranging from 6.625” ID to 60” ID, with material thicknesses from 0.250” to 3”, and lengths up to 60”. Every sleeve is 100% CNC machined to ensure maximum precision and a consistent fit across all applications. We also offer an optional mill-grooved backing strip configuration for enhanced weld prep and fit-up flexibility in the field.
