Carbon fiber composite pipeline reinforcement and repair technology utilizes reinforcing carbon fibers and high and low temperature resistant matrix resins to form a composite material reinforcement layer on the outside of the pipeline. This layer shares the load borne by the pipeline, limits the radial expansion and circumferential tensile stress caused by internal pressure at pipeline defects, thereby achieving the purpose of reinforcing defects and restoring the pipeline's normal pressure-bearing capacity.

2. Technical Specifications for Carbon Fiber Pipeline Reinforcement: Based on the T/CIA group standard, Technical Specifications for Reinforcing and Repairing Chemical Pipelines with Carbon Fiber Composite Materials
■ No welding or hot work required; repairs can be performed under pressure.
■ Simple and quick construction, short operation time;
■ The elastic modulus of carbon fiber is very close to that of steel, which helps the composite material to bear as much pipeline pressure as possible, reduce the stress level of defective pipelines, limit pipeline expansion and deformation, and ensure the safe operation of pipelines;
■ Carbon fiber has a tensile strength of over 3400MPa, making it extremely safe for pipeline repair; furthermore, carbon fiber composites exhibit excellent creep resistance, with their strength remaining essentially constant over service life.
■ The thinness of the carbon fiber composite reinforcement layer facilitates subsequent anti-corrosion treatment;
■ Flexible carbon fiber reinforcement winding and laying methods. It can reinforce defects in circumferential and spiral welds (including high weld reinforcement and severe misalignment); it can also repair irregular pipe fittings such as bends, tees, and reducers.
■ It can be used to repair and reinforce defects such as corrosion, mechanical damage, and cracks, and can also be used for pressure boosting and reinforcement of the entire pipe section. It has a wide range of applications.

1. Shandong Jiangshan Fiber Technology Co., Ltd. continuously reforms and innovates, and independent research and development is the company's core competitiveness. The successful development of FRD resin enables the perfect combination of fiber and resin, providing customers with resin systems that meet various requirements and truly satisfying their needs.
2. In the field of petrochemical pipeline reinforcement, companies such as Shanghai Petrochemical, Yanjing Petrochemical, and Hainan Petrochemical are at the forefront of the industry, having begun adopting a new reinforcement method using carbon fiber woven fabric. Our company, in collaboration with these companies, has developed a special high-temperature resistant FRD-Y180-G01 epoxy resin system for the reinforcement of medium-temperature pipelines. Resin systems with a Tg of 200 and above, developed based on customer needs, are currently under development. We will actively collaborate with relevant companies to develop new products, continuously optimize and upgrade them, and jointly contribute to the development of the oil pipeline reinforcement industry!
