API Normalized Sucker Rods
Weatherford offers a full line of API grade sucker rods. Each rod is manufactured from Special Quality (SBQ) bar stock plus the same stringent quality control measures and careful handling as our High-Strength Rods.
Weatherford API Sucker Rods are manufactured to API 11B specifications and are ISO 9001/API Q1 certified in one of the most modern facilities of its type within the industry. These rods feature fully rolled, cold-formed threads designed to provide a precise, smooth, reinforced thread structure not attainable by normal machine-cut threads. Metal is displaced rather than removed and the resultant cold working strengthens the thread root.
Weatherford rods are cleaned by shot blasting to remove any scale and oxidation; then liberally coated with rust inhibitors and carefully palletized in bundles for safe transport and handling.
