For your buttress connections to be compliant under the 16th edition of the API 5B, you must inspect run-out. When inspecting buttress run-out with a Gagemaker BR-2001, inspectors often question where to place the contact point on the thread. Now, the new API 5B Section 5.3.3.4 specifies the location of the inspection point. When the […]
When inspecting 2⅜” and 2⅞” tubing with an MRP-1000 or MRP-2000, save time by quickly checking the PD at only one location. Because ovality typically isn’t a concern for small diameter tubing, an average of high and low readings is not necessary.
Often on the shop floor you would like to verify the settings of the gage you are using.There are several simple methods to ensure your settings stay correct. Today’s tip covers the MRP® crest diameter and ovality gage and coupling inspection. When using an MRP® crest diameter gage to inspect crest diameter on a coupling, […]
When using a rod standard or gauge blocks to set the “B” dimension (the distance between the shoe and the wear pad) on an MRP® gage, the position of both the shoe and arm are crucial. To ensure proper position when locking an arm, place and hold your finger on the shoe against the standard […]
For Tubing and Casing, properly setting a TH-3002R thread height gage is easy, yet often done incorrectly. The setting standard (1014) has a square-shaped notch and a v-shaped notch. First, use the square-shaped notch, zero the gage. Then, rotate the standard and use the v-shaped notch to verify the gage is correctly zeroed. If the […]
Tired of measuring Buttress Thread groove widths using old Go/No Go gages or by hauling mold samples to an optical comparator? As an easier alternative, Gagemaker now provides a gage to directly measure tooth width easily wherever the part is. The TW-6001 gage comes equipped with a .0005″ reading indicator to inspect those groove widths […]
Correct thread form is important for any type of connection to make up properly. Thread Form Profiles not only help easily check for the correct thread form, proper flank engagement and possible lead error, but you can inspect for burrs by sweeping the profile around the thread cone. For quick reference, please check out the […]
Functional thread rolls are manufactured in matched pairs offset by one-half pitch to allow them to sit in a thread’s helical path (groove). Sometimes inspectors or machinists are unsure if they have properly positioned the rolls in the correct helical path. To avoid such issues, simply use a blue Sharpie® to draw a line in […]
While a certified Gagemaker setting standard is the preferred practice for Straight Threads, in a pinch, you can use gage blocks to set a two-point Gagemaker lead gage without a proper standard. Create a gage block stack-up for the necessary interval then place between the points. Hold the face of the stackup against the fixed […]
A quick check will prevent an easy to avoid incorrect measurement with any ball point gage. Before inspecting, always verify the appropriate ball contact points. As you can do this when the points are on or off the gage, Gagemaker recommends checking points before setting up the gage or if you did not set up […]
