Ultra-Met® Pipe
Ultra-Met pipe is recommended for severe sliding abrasion applications. Produced under strict process controls Ultra-Met pipe possesses a surface with an excellent combination of high resistance to erosion, severe abrasion and moderate impact strength. The Ultra-Met overlay process can be applied to spool sections, pipe bends and fabricated fittings. Wire alloy is deposited upon the carbon steel inner pipe bore. For straight sections or bends, the entire inner surface is welded in one or two layers. Overlayed bends and fittings can be used in conjunction with induction hardened pipe within the total system to afford the additional abrasion resistance needed in areas of extreme turbulence and wear.
Ultra-Met® Pipe - Technical Summary

Forms: Straight or formed pipe
Consult your local St. Lawrence Sales Rep for sizes, shapes and wall thickness
Ultra-Met® Pipe - Approved Welding Rod and Wire
Ultra-Met Pipe can be welded with low hydrogen electrodes on the OD carbon steel base. Studs can also be welded to the carbon steel base plate.
1. AWS E70XX, E80XX and E90XX shielded metal-arc electrodes have been successful for submerged-arc and gas metal arc wire, when welding to the carbon base plate. Low hydrogen flux is also recommended.
2. For butt weld, use St. Lawrence Welding wire 100-W-IM (gas shielded metal arc) or 200-W-ACF (open arc)
Ultra-Met® Pipe - Recommended material processing
We strongly recommend the use of St. Lawrence Steel’s fabrication services to eliminate errors in the processing and fabrication with Ultra-Met® Pipe.
Torch Cutting
Ultra-Met® Pipe can be thermally cut with oxygen-fuel and plasma-cutting techniques. The minimum recommended plate temperature should be +60° F.
Machining
Shearing, punching, or machining is not recommended. We recommend the use of St. Lawrence Steel’s fabrication services to eliminate errors in the processing and fabrication with Ultra-Met® steel plates.
