Required and Optional Testing for Remanufactured Industrial Valves

Posted by

Valve Instrument ShopIndustrial valves require extensive testing before installation to ensure that they perform properly within your facility. Working with a Houston oil and gas valve repair company that conducts these tests can help you reduce downtime for your facilities that can result from the failure of an OEM or remanufactured industrial valve. Here are some of the most important tests that should be conducted on your industrial valves before putting them to work on your processing plant or factory floor. 

Tests Required for All Valves 

Both OEM and remanufactured control valves must undergo two required standard tests established by the American National Standards Institute (ANSI) and the International Standards for Automation (ISA):

  • Hydrostatic tests use pressurized water to evaluate the mechanical components of the valve and to ensure that it is free from any holes or gaps that could allow leakage. If any moisture escapes through the valve within two minutes, the valve must be disassembled and corrected or completely remanufactured to ensure the greatest utility and functionality. 
  • Seat leakage tests evaluate the seal created by closing the valve. Compressed air is forced through the valve to test the functionality of the valve. The amount of air that escapes through the closure section of the valve is measured against the maximum allowable leakage. Failing to meet these requirements requires the repair or remanufacture of the valve until it is in compliance with ANSI and ISA standards. 

Your local Houston industrial valve repair company can provide you with tested and reliable solutions for all your OEM and remanufactured valve replacement requirements. 

Additional Tests for Remanufactured Valves 

While most OEM valves only undergo hydrostatic and seat leakage testing, Houston oil and gas valve repair companies that offer remanufactured valves may also conduct a number of other tests, including the following:

  • Actuator spring testing may be required to determine the current condition of valve springs and whether replacement is required for these components. 
  • Positive materials identification is used to determine the precise mix of materials and alloys used in constructing a valve. This may be necessary to determine the appropriate use for a specific valve and to ensure that the right materials are used for all Houston valve modification or replacement procedures. 
  • Ultrasonic thickness testing can identify areas of wear and tear to ensure the highest quality for remanufactured valves. 

Entrusting these testing procedures to a reliable and local Houston oil and gas valve repair company can help you maintain the highest standards of quality and productivity for your industrial facility.
