API Spec 5B CSG LCSG Round Casing Thread Gauge GCr15 Oilfield Casing Thread Inspection Gauge
Description:
API Spec 5B 18 5/8 CSG / LCSG Round Casing Thread Gauges mainly used for the dimensional inspection and quality verification of oilfield casing round threads. Fully manufactured in strict accordance with the latest API Spec 5B petroleum industry standard, these thread gauges adopt premium GCr15 bearing steel material with high hardness of 60-63HRC, delivering excellent wear resistance, high structural stability and long service life. All gauge tooth profiles, pitch diameters and thread tolerances are precisely calibrated to fully meet petroleum industry inspection requirements, ensuring accurate and consistent measuring results in harsh oilfield working environments.
API CSG & LCSG thread gauges are widely used in petroleum & oil well industry to verify the thread profile, dimension and assembly quality of oil casing pipes. Suitable for oil pipe factory, oilfield inspection laboratory and third-party testing organizations.
Available with master gauge or working gauge, thread plug gauge, thread ring gauge or full set. Every gauge comes with calibration certificate. Each finished gauge is equipped with an official calibration certificate to ensure standardized and traceable measurement results.

Applications:
Buttress casing working thread gauges are mainly used in the petroleum oil and gas industry for measuring
the thread of casings,tubing and pipelines.
Precautions:
1. It is not allowed to touch the working surface of the gauge with your hands, so as not to cause rust.
2. Inspect regularly to see if there is any damage, rust or deformation. If you find that the gauge begins to rust,
you should put it in gasoline and soak it for a period of time, then take it out and wipe it carefully, and apply anti-rust oil.
3. Do not save the working surfaces of the two gauges together, otherwise the two working surfaces
will be glued to each other, and the gauge will be unnecessarily damaged when separated by external force.
4. After used the threaded gauges, it should be wiped clean and stored under dry condition.
