Delongtai (Shanghai) Sealing Technology Co., Ltd. is a specialized manufacturer and supplier of industrial sealing solutions, deeply integrated into the global maritime and offshore engineering sectors. Tracing its corporate origins to a foundation in Singapore in 2004, the company has expanded its operational footprint significantly within China to serve as a critical link between international technical standards and robust local manufacturing capabilities. Headquartered in the Songjiang District of Shanghai, the company has established a strategic network of branches across China’s most vital maritime hubs, including Guangzhou, Qingdao, and Zhoushan.
The company’s identity is defined by its strategic alignment with the shipping and shipbuilding industries. Its presence in Zhoushan and Qingdao—regions renowned for their high concentration of shipyards, dry docks, and port facilities—allows Delongtai to provide rapid response and logistical support to vessels undergoing repair or construction. This proximity to major ports enables the company to supply essential ship materials and sealing components efficiently, minimizing downtime for merchant marine fleets and offshore assets. Operating as a key entity within a broader Singaporean maritime supply network, often associated with the Apex brand, Delongtai leverages decades of professional experience to deliver products that meet rigorous marine safety and performance requirements.
In terms of operations, Delongtai focuses on the production and processing of high-performance sealing technologies designed to withstand the harsh environments typical of marine and heavy industrial applications. The company’s engineering capabilities address the critical need for leak prevention in high-pressure and high-temperature systems found aboard ships and oil platforms. Its portfolio includes precision-engineered solutions such as metal spiral wound gaskets, high-performance asbestos-free jointing sheets, and camprofile gaskets. Beyond basic sealing, the company provides specialized safety products like anti-splash tapes and flange spray shields, which are essential for crew safety in engine rooms and hazardous areas.
While its core reputation is built on serving the maritime trade, Delongtai also plays a significant role in the offshore engineering, petroleum, and petrochemical sectors. By maintaining strict quality controls and adapting to the complex needs of modern vessels and industrial plants, Delongtai (Shanghai) Sealing Technology Co., Ltd. serves as a reliable partner for ensuring the structural integrity and operational safety of fluid handling systems across the Asia-Pacific region.
