Thru-Kote sleeve and fitting systems allow for continuous coating throughout a pipeline by isolating the internal coating from the welding process.
These products can be used in both onshore and offshore applications and constructed to accommodate any size, grade or configuration of piping system. The sleeves and fittings are compatible with Tube-Kote liquid or powder coatings, which are chosen based on operating environment specifics.
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 are designed to isolate the burn-back of the coating and protect the steel substrate. Other benefits include:
Backing ring and heat tape to reduce excessive temperatures
Holiday-free connection area
X-ray compatible with API and ASME
Fast and flexible method of field construction
Thru-Kote U.Bsleeve is an unbelled connection system 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
