Getting ready for API Spec 5B1 with Gagemaker

In the next revision release of Spec 5B1 by API, the industry will be able to meet the requirements by using the Gagemaker MRP Gage System. MRP is the abbreviation for Manual Plug and Ring. When the API 5B1 specification is released ( 2012 ) it will allow a threaded connector to be measured and accepted exclusively with the use of the MRP and the rest of the thread element gages. The MRP series of gages accurately measure internal and external diameters of tapered threaded connectors. The MRP uses two accurately located pivoting shoes that rest on the crests of the threads. The MRP gages are easily preset to size using gage blocks, Mic Tracs, or other types of readily available measuring equipment.

Other thread element gages readily available from Gagemaker are thread lead gages, thread taper gages, thread height gages, and thread profile gages. These gages are readily available and extremely versatile for inspecting a large range of threaded connectors.

Gagemaker Distributor Conference 2012

Gagemaker Thread Gages

Thread Check Inc. attended the Gagemaker 2012 Distributor conference in Houston Texas this past week. Thread Check was represented by its President Bart Kipnes, VP of Sales Mark Koszyk, and General Manager Glenn Belmonte. The conference included training and workshops that covered Gagemakers core group of products including Straight Thread Inspection, Tubing and Casing Inspection,, Rotary Shouldered Connection Inspection, Mud Motor Power Inspection, and Measurement and Calibration.

Gagemaker's products are ideally suited for large diameter inspection as well as accurately inspecting all the critical elements of a thread including lead taper, thread depth, profile, functional diameter and pitch diameter. Inspection Kit packages are available that make implementing a quality thread inspection fast and easy.

Calibrating Thread Comparators

Regarding calibration of internal and external thread comparators:

For the Internal Thread Comparator, calibration requires ispecting for wear only. The segment fingers are made as a unit then cut in half. The only element that can be measured is the form of the thread, and the only issue that would make these unusable would be wear on the thread form.

In regards to the Tri-Roll Thread Comparator, the thread measuring rolls are required to spin so this should eliminate the possibility of wear. Recalibration covers evaluating for wear and damage do to misuse and neglect.

It is important to make sure rolls are not locked down during use.

Recalibration covers inspecting both segments and rolls to original manufacturing specifications

Original manufacturing specifications are proprietary and not for release or publication.

Gage Makers’ Tolerances

Gage Makers tolerances have been established by the American Gage Design Commitee and are referenced for building and calibrating all solid ring gages, plug gages, and fixed snap gages. Gage Maker tolerances are refered to as classes. For example Class ZZ tolerance is an open tolerance or economical tolerance. There are 6 classes of tolerance - class XXX, XX, X, Y, Z, and ZZ.

The Mahr Precimar Linear 100 Measuring System w/MarCheck

The Mahr Precimar Linear 100 Measuring System w/MarCheck is a universal, user-friendly length measuring instrument. The Linear 100 can be used for rapid, precise internal and external measurements up to 100 mm, for both the calibration lab and directly in the manufacturing environment. The unit's simple design makes it possible to carry out fast measurements and adapt quickly to new measurement tasks.

Paired with the new MarCheck measuring and evaluation unit, both measurements and calibrations can be performed quickly and reliably at the touch of a button. Results are clearly shown in large digits on the display screen and can be output via USB or RS 232 ports. The Linear 100 offers a direct measuring range of up to 50 mm (2 in.) and an application range of up to 100 mm (4 in.).

Save Time with the MarCheck Evaluation Unit

Save time by performing calibration checks, such as setting direct-reading measuring equipment or 2-point bore gages with the MarCheck evaluation unit. The Linear 100 with MarCheck also offers a more economical alternative to rings and gage blocks for shop-floor mastering of inner and outer comparative measuring equipment, 2-point measuring instruments, inside calipers, and dial comparator snap gages. Easy-to-use menus guide operators, and measurements are performed systematically using function keys.

Compact in design, and portable for travel the Linear 100 is designed to fit wherever you need it. It features an adjustable 76 x 76 mm (3 x 3 in.) measuring table for precise adjustment of part position when measuring ODs, and a 4 to 40 oz (1 to 11 N) adjustable measuring force that remains virtually constant over the entire measuring range. For ID measurement, the 100 mm (4 in.) x 185 mm (7.3 in.) worktable allows for precision part positioning for measurement. The integrated measuring system is based on the Abbe principle (i.e., the measuring arm and reference are in line) which eliminates cosine errors.

Combined Measurements Without Remastering

Internal/External measurements, as well as Combined Internal/External measurements, are possible without remastering, and easily interchangeable measuring anvils provide increased part measuring versatility. The solid cast body reduces stresses and twisting error and a large digital display provides clear readouts with selectable ID/OD results and preset values.
3 Wire Thread Measuring System
Thread Check's 3-Wire Thread Measuring System adds additional capability to the Mahr Federal Linear 100. Get fast and accurate thread measurement and calibration all in one complete package.
** Sold Separately

No other calibration instrument can offer these combined capabilities, versatility and quality at this price.
