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 PIPE-MAX is a combination grinder and pipe belt sander. The front hard rubber contact roller drives the abrasive belt to grind flat surfaces. It removes weld seams in a straight line, without leaving edges or a wavy finish. For sanding pipes or handrails, the sanding belt follows every contour to grind and polish up to a high-gloss finish. Ideal for stainless steel, aluminum and high-quality metals.
