The rumbling production line rotates, and rubber raw materials are refined and formed in precision molds - our company's flange sealing rings are being mass-produced with millimeter-level precision! Selected from nitrile rubber and fluorine rubber materials, the oil resistance and high-temperature resistance are enhanced through vulcanization process. The corrugated structure design meets the flange sealing requirements and effectively withstands high-pressure leakage. From raw material quality inspection to finished product testing, every process has passed ISO certification, "building a solid safety defense line" for equipment in the petroleum, chemical and other fields.
