Can you Meet the New API Inspection Requirements?

The American Petroleum Institute (API) has released the Sixteenth edition of the 5B Specification for Threading, Gauging, and Inspection of Casing, Tubing, and Line Pipe Threads, with an effective date of July 1st, 2019. The new specification has major changes that companies need to be aware of in order to conform and properly maintain their API license.

  • API 5B 5.5.2 THREAD ADDENDUM
  • API 5B 5.6 ANGLE & THREAD FORM MEASUREMENT
  • API 5B 5.6 & 5.7 REQUIRE BUTTRESS FORM INSPECTION
  • API 5B SEC. 6 DIAMETER, OVALITY, & SIZE GAUGING PRACTICE

Luckily, Bowers Group is the exclusive distributor for the Gagemaker product line in the UK. As the industry standard for API pipe thread measurement, Gagemaker provides quality thread inspection equipment to meet all of your needs and the requirements of both Sections 5 & 6.

Gagemaker’s MRP® Pitch Diameter & Ovality Gauges

The Gagemaker MRP® Pitch Diameter & Ovality Gauges are a key piece of equipment for API compliance. Available from Bowers Group, the MRP® series of gauges is the industry standard worldwide. Whether you call it Crest Diameter, Root Diameter, or Ball PD, Pitch Diameter governs the strength of the actual thread assembly and ensures API dimensional measurement specifications are met.

Total Control Over Your Quality

The Gagemaker MRP® gauges measure the internal and external pitch diameters of tapered threaded connections. Any slight variations in diameter or ovality are immediately detected with these precision gauges granting you total control over your quality. These versatile gauges easily adjust to measure thread diameters ranging from 1½” – 20”. The ability to inspect a range of diameters with one gauge eliminates the need for a room full of ring or plug gauges.
