UPCO, Inc. has achieved a Sigma Six level of quality in regard to field failures. During the past 7 years there have been only six rod failures due to manufacturing or field defects while the company has produced and shipped over 1,765,000 rods. This is a failure rate of less than 3.4 failures per million.
UPCO Polished Rods are quality at its best. We start with special quality AISI steel alloy rods that are cold finished, straightened, and eddy current inspected, then stored and handled with padded racks and fabric slings.
After machining the pins and applying the threads the rods are polished by the use of centerless grinders. Centerless grinders provide a cylindrical bar with less variation in diameter or concentricity. After the application of a special marine coating the rods are packaged in waxed tubes to prevent atmospheric damage and metal thread protector are attached. For ocean transit or tropical environments the rods can be packed in a sealed plastic sleeve.
