Steel-plastic combined anti-corrosion storage tanks feature a polyethylene (PE) lining as the anti-corrosion material, formed through the rotational molding process. This process integrates the lining plastic with the steel body through a stamped steel mesh, ensuring the steel and plastic layers are firmly bonded and do not easily separate. The lined product boasts excellent corrosion resistance and a long service life. The thickness of the lining can be customized to meet customer requirements (typically 15-20mm). The internal equipment volume ranges from 1m3 to 250m3. It resolves the delamination issue caused by the differing thermal expansion and contraction of plastic and steel, enhancing the product's reliability. The product can be used at temperatures up to 95℃ and as low as -40℃, catering to varying temperature differences across different regions. It is a cost-effective, safe, and reliable anti-corrosion equipment that is highly favored by customers.
