T/FJSX 0001-2023 Double hot-melt fusion plastic steel liner and reinforcing tube with external covering

Scope

Main technical content: The double-hot-melt steel-plastic inner-lining and outer-coating reinforced pipe is made of a cold-rolled steel strip welded mesh pipe as the reinforcing frame, with polyethylene (PE) or heat-resistant polyethylene (PE-RT) as the base material. It is a thermoplastic pressure-resistant composite pipe formed by continuous extrusion. This product combines the excellent characteristics of metal materials and the corrosion resistance of polyethylene plastics. Compared with pure polyethylene plastic pipes, it has higher pressure resistance and creep resistance, good ring stiffness and impact resistance, low linear expansion coefficient and thermal conductivity, smooth inner wall without scaling, light weight, convenient transportation and construction, simple welding process, and good hygiene. It is suitable for conveying media with a temperature range of -20°C to 85°C, and has a service life of up to 50 years. In recent years, through continuous innovation and technological improvement, the product performance has been optimized and enhanced, the product specifications have been expanded, and the pressure resistance and safety performance have been greatly improved. The connection methods are more diverse and more reliable. It is increasingly widely used in industries such as petroleum, chemical, metallurgy, pharmaceuticals, shipping, and mining, as well as food. The formulation of the standard aims to serve production and manufacturing enterprises and meet market development needs. It supplements some special specification series with high market demand, increases the structural types and connection diagrams of composite reinforced pipes, and revises and supplements the main dimensions of composite pipes to guide design units and users in selecting models and manufacturing enterprises in standardized production to ensure the safety of composite pipes in use; it sets requirements for the manufacturing process and welding process evaluation of comp
