Pg Steel Conduit Threads

Pg Steel Conduit Threads per DIN 40430 STEEL CONDUIT THREAD; DIMENSIONS

Pg Steel Conduit Threads are manufactured in accordance with DIN 40430 STEEL CONDUIT THREAD; DIMENSIONS. The Pg thread series is designed specifically for steel conduit because of the thin wall cross section of the steel conduit. The thin wall thickness requires a shorter profile thread that will not break through the outside diameter of the steel conduit during the machining process. The 80° included angle of the Pg thread form gives a shorter profile than the more common 60° included angle found in the Unified National thread series and the Metric thread series. There is some discussion about replacing the Pg Steel Conduit Thread per DIN 40430 with a 60° version as specified in BS EN 50262 CABLE GLANDS FOR ELECTRICAL INSTALLATIONS and/or DIN EN 50262 METRIC CABLE GLANDS FOR ELECTRICAL INSTALLATIONS.

Standard Pg Steel Conduit Thread Sizes per DIN 40430 STEEL CONDUIT THREAD; DIMENSIONS

Pg Steel Conduit Thread Plug Gages per DIN 40431 P2 STEEL CONDUIT THREAD; THREAD GAUGES, "GO" AND "NOT GO" THREAD PLUG GAUGES

The standard: DIN 40431 P2 STEEL CONDUIT THREAD; THREAD GAUGES, "GO" AND "NOT GO" THREAD PLUG GAUGES specifies the requirements for the thread plug gages. A unique aspect of the Pg Steel Conduit Thread Plug Gage is that the NOGO member is a plain cylindrical gage. This actually works because as the thread is machined the crest of the thread form comes to a point. As the thread size is changed, the position of the point changes and thus can be measured. The GO member works in the normal manner by checking the maximum material condition.

Pg Steel Conduit Thread Ring Gages per DIN 40431 P1 STEEL CONDUIT THREAD; THREAD GAUGES, "GO" AND "NOT GO" THREAD RING GAUGES

The standard: DIN 40431 P1 STEEL CONDUIT THREAD; THREAD GAUGES, "GO" AND "NOT GO" THREAD RING GAUGES specifies the requirements for the thread ring gages. A unique aspect of the Pg Steel Conduit Thread Ring Gage is that the NOGO ring is a plain cylindrical gage. This actually works because as the thread is machined the crest of the thread form comes to a point. As the thread size is changed the position of the point changes and thus can be measured. The GO ring works in the normal manner by checking the maximum material condition.
