With the rising demand for industrial corrosion protection, rubber lining for pipelines is embracing a broad market. Rubber-lined steel pipes are compounded with an internal rubber layer inside steel tubes. Featuring acid & alkali resistance and erosion resistance, they effectively protect metal pipelines from corrosion damage, suitable for the transportation of corrosive media in desulfurization, chemical, mining, sewage treatment and other scenarios. Materials such as butyl rubber and EPDM can be selected according to working conditions, with standardized vulcanization construction and spark testing to guarantee anti-corrosion quality and extend pipeline service life, helping industrial projects cut costs and improve efficiency.
