Greetings everyone, a pump was recently removed from service due to a leak in one of its gaskets. Following maintenance, we are now seeking to conduct qualification tests before reinstalling it. I seek clarification on the following: 1. What specific standards or codes will be utilized for its qualification? 2. Which tests, such as High-Pressure Testing or Pneumatic Testing, should be conducted? Thank you for your guidance.
Hello, since the leak is not coming from the main casing or its connected nozzles, there is no need for a hydrotest of the casing. However, if welding is performed for the joint repair, X-ray and NDT inspections are necessary. Also, a service test is required after installation.
Can you identify the specific gasket needed for the pump by checking its nameplate and determining if it meets the original equipment manufacturer (OEM) standards?
Which type of pump is it?
Thank you for the feedback. This centrifugal pump, compliant with API-610 standards, features a Teflon gasket. The crucial query at hand is whether the pump should undergo testing at the same pressure as the qualified piping system, or if a simple leak check suffices. In other words, if the system was certified at 10bar, is it necessary to subject the pump to a 10bar hydrostatic test? Your insight on this matter is greatly appreciated. Thank you.
Answer: 1. What specific standards or codes should be followed when conducting qualification tests for pump reinstallation? - When conducting qualification tests for pump reinstallation, it is important to follow industry standards such as API (American Petroleum Institute) standards, ASME (American Society of Mechanical Engineers) codes, or manufacturer-specific guidelines.
Answer: - Common tests that should be conducted for pump qualification before reinstallation include High-Pressure Testing to check for leaks, Pneumatic Testing to assess the integrity of the system, and Performance Testing to ensure the pump functions as expected.
