ActiveGauges for pipe threads with 55 degree thread angle where pressure-tight joints are made on the threads - Part 1:Verification of parallel internal and taper external threads
55°密封管螺纹量规 第1部分：用于检验圆柱内螺纹与圆锥外螺纹
Application Summary AI generated
This standard specifies the design, dimensions, and tolerances for gauges used to verify parallel internal and taper external pipe threads with a 55-degree thread angle, ensuring pressure-tight joints. It is applied in the manufacturing and quality control of threaded pipe connections in industries such as plumbing, gas, and hydraulic systems, where leak-proof sealing is critical. The standard is used by metrology labs and production facilities to inspect thread conformity and interchangeability.
