About Us

About Junyue Group

Junyue Group is a comprehensive enterprise integrating R&D, manufacturing, and global sales of piping system components. Headquartered in Weifang, Shandong — the renowned "International Kite Capital" — the group specializes in ductile iron grooved pipe fittings, integrated pipe supports and hangers, valves, OEM castings, and welded short pipes for fire protection, HVAC, petrochemical, power, and water-treatment applications. The group operates through three coordinated entities: Shandong Junyue International Trade Co., Ltd. (global trading), Shandong Junyue Pipeline Technology Co., Ltd. (manufacturing), and Weifang Changle Jixiang Casting Co., Ltd. (foundry). This vertical integration — from casting to finished fittings — enables consistent quality control and competitive cost performance across the entire supply chain. Production is built on four imported automated casting molding lines and eight medium-frequency electric furnaces, including two Danish DISA vertical automatic molding lines and two American Inductotherm 4T dual-powered melting systems. A self-owned, internationally standardized laboratory equipped with advanced testing and inspection instruments guarantees the sustainability of excellent casting quality. Quality and compliance are certified to ISO9001:2015, ISO14001:2015, and ISO45001:2018, with American UL, CE, and other international quality and safety approvals, plus domestic fire-protection industry certifications. Products are verified by SGS and BV inspections and exported to Europe, South America, Africa, Southeast Asia, the Middle East, and beyond. Guided by the philosophy of "quality sharing, value win-win," Junyue Group is committed to delivering reliable piping solutions and responsive service to distributors, contractors, and OEM partners worldwide.
