1. If you need the mill material certification and/or heat treatment tensile test results, call Quality Assurance (QA) at 918/445-7668. Furnish the product size, type, heat code and manufacturing date and the requested information will be faxed to you within 24 hours of your inquiry.

2. If a problem should arise, complete this form (QA0005) as accurately and completely as possible. This information and the accompanying samples will serve as the basis for determining the failure root cause.

3. Do not clean samples submitted for analysis. The samples may contain important evidence that help determine well conditions present at the time of the failure.

4. All failure samples must include the stamped upset end with the heat code and date of manufacture.

  • For Body Failures: - Include approximately 12 on both sides of the break. If the break is within 24 of an upset, include the upset and 12 on the other side of the break. If a tensile pull test is required, include a 24 section of rod body to be used for physical testing.
  • For Pin and Upset Failures: - Include the upset end with the broken pin and the mating coupling or the pin end with the galled threads and the mating coupling. If a tensile pull test is required, include a 24 section of rod body to be used for physical testing.
  • For Coupling Failures: - Depending upon the type of failure, include either both halves or the entire coupling.

5. Tag each sample piece with the following information: (1) company name, (2) lease name & number, (3) number of rods from surface to failure and (4) your name & telephone number.

6. Carefully pack the failed sample halves to avoid mechanical damage to the mating fracture surfaces during shipment.

7. Immediately ship the samples and the completed QA0005 Form to Norris Sucker Rods. In Midland, Texas send the samples to the attention of Technical Services or in Tulsa, Oklahoma send the samples to the attention of the Quality Assurance Lab. In case tracing the shipment becomes necessary, you should retain the shipping receipts or notes until you have been informed by phone that we have received the samples and the completed QA0005 Form.

  • If you ship the samples by motor freight, Federal Express or UPS, use the following physical address: 7900 West I-20, Midland, Texas 79706 (915/561-8101) or 4801 West 49th Street, Tulsa, Oklahoma 74107 (918/ 445-760 or 800/767-7637).
  • If you mail the samples using the USPS, use the following address: PO Box 60575, Midland, Texas 79711-0575 (915/561-8101) or PO Box 1496, Tulsa, Oklahoma 74101-1496 (918/445-7600 or 800/767-7637).
  • In certain cases, shipment by air freight may be necessary. Airfreight shipments should be addressed to 7900 West I-20, Midland, Texas 79706; Attention  Technical Services (915/561-8101). The air waybill must be marked  Notify Upon Arrival. Please call and inform Technical Services as to when and where to expect the arrival of your shipment.

8. After the samples have been evaluated, a Product Failure Evaluation (PFE) Report will be mailed stating the failure root cause. Typically the PFE Reports will be one of two types and will be presented to the individual responsible for the solution or problem.

  • Non-Warranty Related: Most failures will be the direct result of certain pumping and/or well conditions. For these situations, Norris will make an effort to recommend possible corrective actions.
  • Warranty Related: Should a question of defectiveness for any Norris Sucker Rod or Coupling arise while covered by warranty, the issue shall be submitted to a qualified and accredited independent laboratory for opinion. When warranty adjustments for steel sucker rods are considered, Norris will request that the customer submit one (1) copy of the well servicing invoice, with the subject fishing cost properly identified, to: Norris Rods, PO Box 1496, Tulsa, Oklahoma 74101-1496, Attention  Quality Assurance Manager. Upon arrival of the warranty reimbursement claim, a check  for the amount of the fishing cost only  will be forwarded to the person filing the warranty claim. The well servicing company will not be reimbursed directly.
