![]() ![]() It includes requirements for marking, inspection, a uniform method of rating, and design loading for the equipment. This test verifies the performance of non-metallic seals and molded sealing assemblies used as pressure-controlling and/or pressure-containing during exposure to low and high temperatures.API Drilling Equipment Standards - 2009 Catalogue Spec 4F Drilling and Well Servicing Structures Specification 4F covers the design, manufacture, and use of steel derricks, portable masts, crown block assemblies, and substructures suitable for drilling and well-servicing operations in the petroleum industry. This test determines the ability of the annular packing unit to maintain control of wellbore pressure while stripping drill pipe and tool joints through the closed packing unit without exceeding a leak rate of 4 liters/min. ![]() This test shall be accomplished by obtaining access to the packing unit and performing a wellbore pressure test every 20th packing unit access. This test determines the ability of the blowout preventer to undergo repeated packer changes without affecting operational characteristics. Testing simulates wellbore pressure testing from 200 psi to 300 psi once per week for one year of service. This test simulates closing and opening of the blowout preventer once per day. This test determines the piston closing pressure necessary to maintain a seal as a function of wellbore pressures up to full rated working pressure of the blowout preventer. ![]() Tested to 115% of API fatigue test target*ĭesign verification performance testing in accordance with API-16A requirements were third party witnessed and included: Our commitment and dedication to develop market leading technologies and supported with in-house product verification testing, is featured with the successful introduction of the WellProtek ® API-16A licensed and 16AR compliant annular units.
