These patents optimize key processes: a precision cold rolling mill sprays pickling solution to clean pipe surfaces before rolling, preventing scratches\u00a0<\/span><span class=\"\">; a specialized cold drawing die uses a drive mechanism to unlock the mold base, ensuring stable installation and easier changeovers\u00a0<\/span><span class=\"\">; and a pickling system recycles acid liquor through a filter tank, improving surface quality while reducing environmental impact\u00a0<\/span><span class=\"\">. The company also developed a patented heat treatment transfer device that increases lifting efficiency and ensures consistent quenching<\/span><span class=\"\">.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\"><span class=\"\">\u00a0 In addition to process patents, Kangxin holds a patent for a high-strength, impact\u2011resistant seamless steel pipe <\/span><span class=\"\">. This design places an outer tube, a middle tube, and an inner tube with a buffer layer between each. The inner buffer layer contains elastic cushions and impact\u2011absorbing particles, while the outer layer uses foam carbon and energy\u2011absorbing balls\u00a0<\/span><span class=\"\">.
