DKM socket weld joints are designed for use on potable water or sewage pipelines with high-pressure mains and no thrust blocks.
They can be used in applications that require corrosion resistance for use in aggressive ground conditions.
DKM socket weld joints are made from ST37, ST52, API, ASTM A106, X42, X52 or X60 grade steel finished blue for water applications or black for sewage applications.
A choice of three-layer PE (1.8-2.2mm thick), three-layer PP (1.8-2.2mm thick), or FBE (500µm thick) protective coatings is available. The joint is lined with cement mortar to DWI 25 (1) (a).
DKM socket weld joints protect against corrosion without leakage or minimum longevity of life.
