INSULATED JOINTS

Monolithic Joints for Electrically Isolating Pipelines

INSULATED JOINTS

TUBE TURNS INSULATED JOINTS are a pre-fabricated, non-separable, union used to isolate specific sections of pipelines to prevent corrosion caused by stray electrical currents or interference from other pipelines and power transmission cables.

ADVANTAGES OF TUBE TURNS DESIGN COMPACT Tube TurnsInsulated Joints are designed to produce a relatively compact overall length without the use of expensive pipe pups. The heat from normal welding will not affect the mechanical or electrical integrity of Tube Turns Insulated Joints. BOLTLESS The “W” series Insulated Joint is designed to satisfy customers that require a boltless construction for ease of final wrapping and coating after finalinstallation of the pipeline. FULL SCALE IN-HOUSE TESTING Tube Turns is fully qualified to provide Magnetic Particle, Ultrasonic, and Liquid Penetrant examination in-house along with the required NDE test reports to meet customer requirements. SINGLE PIECE CONSTRUCTION The Tube Turns Insulated Joint is of Monolithic construction designed specifically with regard to the pipeline requirements. This designinsures the precompression of the sealing gasket during assembly and enables a perfect seal to be formed against internal and external environments. TRIPLE PROTECTION 1.) Insulated gaskets prevent metal-to-metal contact across the Insulated Joint. 2.) All internal cavities of the Insulated Joints are filled with a special dielectric compound to provide an additional electrical barrier. 3.) Eachmetal component is individually coated with two coats of epoxy paint.

MATERIALS OF CONSTRUCTION The “W” type Insulated Joint has three basic metallic components; two hubs and a yoke. Two groove welds in the yoke lock the Insulated Joint in an integral unit. STANDARD MATERIALS: ASTM A694/ASME SA105 or SA 106 Gr.C (Minimum Yield 52,000 psi) HIGH YIELD MATERIALS AVAILABLE UPON REQUEST: ASTM A707ELASTOMER O-RINGS: Viton O-rings are standard in each Insulated Joint. Other O-ring compounds are available upon request. INSULATED GASKET MATERIAL: Epoxy base/glass fiber reinforced high strength laminate. COATING: Epoxy Base Paint. Coal Tar Epoxy available upon request.

WELDED INSULATED JOINT DIMENSIONS When ordering, please specify bore required. Tube Turns Insulated Joints are normally thrubored to the same ID as the matching pipe. One or both ends can be taper bored at customer request. Joints also available in sizes not listed and for higher pressure ratings.
