Pipeline reinforcement system

1. Carbon fiber composite pipe reinforcement and repair technology uses reinforced carbon fiber and high and low temperature resistant matrix resin to form a composite reinforcement layer outside the pipe to share the load the pipe bears and limit the radial expansion and hoop caused by internal pressure at the pipe defect Tensile stress, so as to achieve the purpose of reinforcing defects, and restore the normal pressure capacity of the pipeline. 2. Technical specifications for carbon fiber pipeline reinforcement, according to T/CIA group standards, technical specifications for carbon fiber composite material reinforcement and repair of chemical pipelines

Principle of Pipeline reinforcement

2. Technical specifications for carbon fiber pipeline reinforcement, according to T/CIA group standards, technical specifications for carbon fiber composite material reinforcement and repair of chemical pipelines

Characteristics of Pipeline reinforcement

■ No welding and no fire, can be repaired under pressure

■ Simple and fast construction, short operation time;

■ The elastic modulus of carbon fiber is very close to the elastic modulus of steel, which is helpful for the composite material to bear the pressure of the pipeline as much as possible, reduce the stress level of the defective pipeline, limit the expansion and deformation of the pipeline; ensure the safe operation of the pipeline;

■ The tensile strength of carbon fiber is more than 3400MPa, which is extremely safe for pipeline repair: and the carbon fiber composite material has excellent creep resistance, and its strength remains basically unchanged with the increase of service time;

■ The thickness of the carbon fiber composite material reinforcement layer is small, which is convenient for subsequent anti-corrosion treatment;

■ Carbon fiber reinforced winding, flexible laying method. It can repair the defects of girth weld and spiral weld (including high weld residual height and serious wrong edge): it can also repair irregular pipe fittings such as elbows, tees, large and small heads;

■ It can be used to repair and reinforce defects such as corrosion, mechanical damage and cracks, and can also be used to enhance the pressure of the entire pipe section. Wide range of applications.

Technology Advantages

1. Shandong Jiangshan Fiber Technology Co., Ltd. is constantly reforming and innovating. Independent research and development is the company's core competitiveness. The successful research and development of FRD resin has made fiber and resin perfectly combined, and can provide customers with various resin systems. satisfy customer needs. Normal temperature pipeline strengthening and repairing construction process

2. Regarding the reinforcement of petrochemical pipelines, Shanghai Petrochemical Yanjing Petrochemical Hainan Petrochemical and others are at the forefront of the industry and have begun to adopt a new type of reinforcement method of carbon fiber woven cloth. Our company cooperates with the above enterprises to develop a special high-temperature-resistant FRD-Y180-G01 epoxy resin system, which is used for the reinforcement of medium temperature pipelines. The resin system of Tg200 and above developed according to customer needs is under development. We will actively cooperate with related companies to develop new products, continuously optimize and upgrade, and jointly contribute to the development of the petroleum pipeline reinforcement industry!
