• Thru-Kote™ 

    Thru-Kote™ is a welded connection system for joining internally coated line pipe and piping systems.




    The Thru-Kote connection system utilizes a patented insert sleeve designed to protect the internal coating during the welding process.  

    Thru-Kote insert fittings provide the same protection and can be fabricated for any configuration, providing an economical and flexible method for field construction, tie-in's, terminations, modifications and repair of internally coated lines.

    These products are compatible with all Tube-Kote™ coatings and can be used in both onshore and offshore applications. Please contact your Tuboscope representative for accurate coating selection.


    Thru-Kote Advantages 
    During the welding process, heat generated within the pipe will burn back the internal plastic coating approximately 1-2 inches from the welding seam. Thru-Kote sleeves and fittings isolate the burn-back of the coating and protect the steel substrate.  

     Other benefits include:

    •  Backing ring and heat tape  reduce excessive temperatures 
    •  Holiday-free connection area 
    •  X-ray compatible with API and ASME 
    •  Compatible with Tube-Kote™ coatings 
    •  Suitable for onshore and offshore applications 
    •  Accommodates all configurations of piping systems 
    •  Fast and flexible method of field construction 


    Thru-Kote Configurations  

    •  Thru-Kote U.B™ sleeve is an unbelled connection system for 2" - 42" line pipe designed    to protect internal coatings during welding 
    •  Thru-Kote is a belled connection system allowing for a non-restricted I.D 
    •  Thru-Kote insert fittings are fabricated for multiple configurations that aid in  modifications or repairs: tie-ins, terminations, flanges and elbows
