Rankin Industries' Rantube, a large diameter tubular hardfacing electrode, combats part wear in heavy industry caused by severe abrasion, erosion, impact, and heat.
The electrode's deposition rates are up to 6.5 PPH for the 7/16 in. (11 mm) size. The in. electrode is designed for all position welding and can be used at low amperage to hardface thin edges on tillage tools and similar parts.
The electrode be applied to heavy industry parts made from cast iron, manganese steel, and mild steel without preheat. High-carbon and alloy steels may require preheat.
The color-coded electrodes are available in three large diameters: in. (6 mm), 5/16 in. (8 mm), and 7/16 in. (11 mm).
Design features include a graphite end seal for quick arc start; flux coating to prevent damage if dropped and to allow non-heated storage; high density alloy powder fill; steel case that seals the tubular section containing alloys to prevent contamination, moisture pickup, and alloy loss if the electrode is dropped. The -in. (6 mm) fits all electrode holders.
