Pre Hone Tubes have been developed as per ASTM standard. These fluid transferring pipes are made of alloy metal. Round in appearance, these thick walled pipes have specific outer dimension range and standard thickness range. Advanced hot rolled manufacturing technology has been used to design these pipes. Light in weight, these pipes are perfect for designing engineering components and machine parts. Non-oiled polished surface, smooth inner surface design, standard tolerance level, spiral welded line design and long lasting quality are the key aspects of these pipes.
