Photosensitive FRP for Directional Drilling Crossing
Photosensitive fiberglass is a formable sheet composed of modified acrylic resin, photoinitiator and glass fiber reinforcement material. It is fixed onto the surface of pipeline anti-corrosion coatings on-site by winding or wrapping, and can cure rapidly under sunlight or ultraviolet lamps. After curing, it possesses extremely high mechanical strength, and is widely adopted for pipeline protection during horizontal directional drilling crossings, as well as anti-corrosion protection of storage tanks, steel structures and other facilities.
Features
-
Ultra-high Mechanical StrengthTensile strength ≥300 MPa, bending strength ≥300 MPa, impact resistance ≥24 J. It features high hardness, excellent wear and scratch resistance, and can withstand scratches caused by a 50 kg heavy load
-
High-efficiency Construction at Low TemperaturesConstruction is not restricted by low-temperature environments. It can be fully cured within 2 hours under natural sunlight and reach the designed strength after only 1 hour, delivering high construction efficiency
-
Strong Environmental CompatibilitySolvent-free, eco-friendly and non-toxic material. It forms firm bonding with mainstream anti-corrosion coatings such as 3PE, FBE and epoxy, featuring outstanding compatibility
Application Areas
-
Oil & Gas Directional Drilling CrossingsPrimarily applied to formations prone to scratching pipeline anti-corrosion coatings, such as rock, cobble and gravel layers, especially suitable for long-distance, large-diameter directional drilling crossing projects -
Long-distance Large-diameter Pipeline ProjectsCompatible with pipelines of all calibers ranging from DN80 to DN1200, used for crossings under mountains, expressways and rivers -
Reinforcement & Repair of Anti-corrosion CoatingsWear-resistant protection and damage repair for joints, elbows and irregular sections of pipelines coated with 3PE and FBE
