Thread Quality Control Series: Part 2 - Powered Gaging of Tapered Pipe Threads

In part two of our Thread Quality Control Series, we discuss the powered gaging methods of tapered pipe threads. Hand Gaging of NPT Threads: https://www.newvistacorp.com/hand-gag... To learn more about our solutions for power thread gaging, visit: https://www.newvistacorp.com/ VMKT3 Pipe threads are manufactured in a variety of forms. The main types are straight and tapered pipe threads. Straight pipe threads are gauged with the "GO" and "NO-GO" gauging process, just like regular threads, but the tapered pipe threads require an entirely different gauging process: a series of L checks First, the L1 check, second the L2 or L3 check, depending on whether you have external or internal threads and third, the six step check. For this video, we will be focusing on the L1 check, as it is the most common in powered pipe thread verification. To learn more about these checks, visit our post detailing the hand gauging of NPT threads; a link will be available in the description below. The powered L1 check is not materially different than that in hand gauging. The process starts by running a tapered thread gauge into or onto a part's threaded feature to the point of stall. If the part is good, then the gauging flat or notch will be within one turn high and one turn low relative to the face or end of the part. To achieve this, the thread verification unit has two sensors to track the position of the gauge. This will ensure that the gauge has gone far enough, but not too far. There are two methods of L1 gauging, depending on the condition of the parts, the single step or two step. For most applications the single step process is sufficient. This process consists of running the thread gauge member in only once. Occasionally the parts are dirty or rough enough to the point where the two-step process is necessary. The two-step process works like this first; the thread gauge member is run in or on to stall at a high torque level for a seating or conditioning cycle, then the thread gauge member is backed away slightly and then run in or on a second time. For the gauging cycle at a torque level that is lower to correspond to what would be expected of hand gauging. Just as with "GO" and "NO GO" thread verification, powered verification of pipe threads adds speed, efficiency and accuracy to your thread quality control process while still providing results correlatable to hand gauging.
