In 2016, China`s Hong Kong-Zhuhai-Macao Sea-crossing Bridge project was open to public bidding for pipe manufacturers across the country. The BWFRP pipe developed by SZXB passed stringent tests on key performance indicators such as corrosion resistance and impact resistance. It became the project`s cable protection sleeve supplier.
Today, the high-performance BWFRP fiber braided pultruded cable protection sleeve ("BWFRP pipe") and other products developed by SZXB are sold to more than 30 countries and regions around the world. Wuhan Metro, Zhaoqing Underground Comprehensive Pipe Gallery, Beijing Daxing Airport, Chengdu Tianfu Airport, Hebei Xiong'an New District Project and many other key projects across the country have been widely used.
BWFRP pipe is a new type of composite pipe. It uses high-performance alkali-free reinforced fiber and high-performance resin as raw materials. It has a unique production process and high technical content. The BWFRP pipe formed by continuous fiber online complete weaving, winding and pultrusion has a three-layer structure: The inner and outer layers are both cross-woven layers, and the middle is a circular and longitudinal composite reinforcement layer. Due to the characteristics of raw materials and production processes, BWFRP pipes have the characteristics of high ring stiffness, strong stretch, corrosion resistance, waterproof, high and low temperature resistance. Xinbaotong BWFRP pipes make up for the shortcomings of plastic coated steel pipes, such as easy corrosion and eddy current electromagnetic. It also makes up for the poor high temperature resistance and impact resistance of PVC pipes and MPP pipes. This is the case, China Southern Power Grid`s "New Technology Promotion and Application Catalogue" writes it like this: It replaces traditional plastic pipes and plastic-coated steel pipes, and has good overall economic benefits.
