The energy sector is hot right now, and so is pipe production. Finding the optimum material for making pipe for this industry is tricky. Low-alloy carbon steels tend to be strong, but lack corrosion resistance. Stainless steels resist corrosion but lack strength. Cladding low-alloy carbon steel with a thin layer of a corrosion-resistant alloy is a suitable process, one that AWS Schaefer has devised for manufacturing such pipes.
The PTX Eco Smart is a multi-functional grinding and polishing system for flat surfaces and open or closed pipe constructions. Grind from coarse to very fine finishes, and burnish to a high-gloss finish. Work with stainless steel, steel and nonferrous metals (aluminum, brass, bronze and copper), wood, and rigid plastic.
