Joining techniques
Steel line pipe for water and wastewater systems is available with a full range of connections to suit the intended application. The requirements and designs are standardized in DIN 2460 and EN 10311.
Depending on the operating conditions of a pipeline, such as the operating pressure and the transported medium, various joining techniques are available – and thus a variety of options and diverse degrees of freedom – for the installation of the pipeline and its subsequent operation.
Basically, we differentiate between mechanical and welded pipe joints. Examples of non-permanent mechanical joints are couplings and flanges. They are predominantly used in non-buried pipelines. As to joint welding, we offer butt-weld and slip-welding options.
Slip welding joint
Description
Special design for aggressive media
Properties
Optimally suited for water and wastewater pipes, force-locking, with axial conductivity for cathodic corrosion protection, suitable for open-cut pipeline method. Nondestructive testing possible. During welding, the joint area can be protected with suitable sealing materials.
