Tightening Torques Screw-in plug for DIN EN ISO 9974 and ISO 1179 Form E

Product catalog summary

Tightening Torques for Screw-in Threads

Overview: This document provides the recommended tightening torques for screw-in plugs made of steel, applicable to both imperial and metric threads as per DIN EN ISO 9974 and ISO 1179 Form E standards. The torques are specified for different materials, including steel and various aluminum alloys.

Imperial Thread Specifications:

Materials: Steel and aluminum alloys (F22, F28, F38, F45).
Pipe Outer Diameters: Ranges from 6 to 42.
Torque Values: Provided for each material and diameter, with steel having the highest values.

Metric Thread Specifications:

Materials: Steel and aluminum alloys (F22, F28, F38, F45).
Pipe Outer Diameters: Ranges from 6 to 42.
Torque Values: Similar structure to imperial, with specific values for each material and diameter.

General Notes:

The values are applicable only for galvanized steel couplings and specified counter-materials.
Screw-in plugs must be greased before installation.
Assembly torques have a permissible tolerance of ±10%.
Using reduced or higher torques can affect the maximum operating pressure.
Reduced torques require securing the coupling against external loosening forces.
