DIN 7604 is a standard that specifies the technical requirements for hexagonal head and flange threaded plugs. Hexagonal head and flange threaded plugs are pipeline connection elements and are used to close threaded holes in unused pipelines or to isolate the corresponding section of the pipeline.
Threaded plugs with hexagonal head and flange have a hexagonal head that allows for easy and convenient removal and installation of the plug. The flange of the plug allows it to be fixed to the pipeline with bolts and nuts.
Fastening group DIN 7604
DIN 7604 plugs belong to the stainless steel fastener group.
Materials for the manufacture of DIN 7604 plugs
DIN 7604 plugs are made of the following materials:
- Steel, which can be additionally coated with zinc or zinc plated. Zinc (Plated) protects against corrosion if the fastener is to be used in aggressive environments.
- Stainless steel. Steel grade A4 allows the fasteners to be used at significant temperature fluctuations and in aggressive and humid environments.
Application range of DIN 7604 plugs
Threaded plugs with hexagonal head and flange have the following main applications:
- Water supply: used to close threaded holes in water supply pipelines.
- Heating and ventilation: used to close threaded holes in heating and ventilation pipelines.
- Oil and gas industry: used to close threaded holes in oil and gas pipelines.
- Chemical industry: used to close threaded holes in pipelines transporting chemicals.
- Threaded plugs with hexagonal head and flange are reliable and easy-to-use pipeline connection elements. They provide hermetic closure of threaded holes and protect the pipeline interior from contamination and other environmental influences.
