Tube Turns® Pipe-Type Insulated Joints

Brand: Sypris Technologies

Tube Turns® Pipe-Type Insulated Joints are monolithic, boltless, non-separable, pre-assembled and pre-tested units used to electrically isolate piping or pipeline segments and adjacent equipment.

Selective cathodic corrosion, risk to metering or monitoring equipment, and other unpredictable damage can result from introduction of stray electrical currents, which can come from a number of sources – adjacent electrical transmission lines, parallel pipelines, geomagnetic fields, flow-induced static charges, etc.

The propagation of current flow along the length of the piping or into attached equipment can be prevented by use of electrical isolation devices, such as monolithic insulated joints.

A key feature of Tube Turns Pipe-Type Insulated Joints is the inclusion of ready-to-weld pipe ends matched to the customer’s pipeline outside diameter, internal bore, wall thickness, and material. Stock quantities available for quick delivery.
