EN1092

Standardized & Interchangeable
Fully compliant with the EN1092-1 European standard, with unified dimensional specifications and connection dimensions. It can be perfectly matched with pipes and valves of the same standard, realizing efficient interchangeability and reducing compatibility risks in project assembly.
Wide Range of Pressure & Size Options
Covers multiple pressure classes such as PN10, PN16, PN25, PN40, and size ranges from DN15 to DN3000. It can meet the application needs of low, medium and high-pressure pipeline systems, and is suitable for various industrial scenarios including petroleum, chemical industry and machinery.
Excellent Sealing Performance
Optimized sealing surface design (RF/FF/RTJ) ensures uniform stress distribution after installation. Cooperating with professional gaskets, it can effectively prevent medium leakage, and has stable sealing effect even under cyclic temperature and pressure changes.
High Structural Strength & Durability
Adopts forging or precision casting process, with dense internal structure of the product, no porosity or cracks. It has strong pressure-bearing capacity and corrosion resistance, and can maintain long-term stable operation in harsh working environments.
Easy Installation & Maintenance
The product structure is designed to be easy to align and assemble. On-site installation does not require complex processes, which saves labor and time costs. During maintenance, it can be quickly disassembled and replaced, reducing the downtime of the pipeline system.
Cost-Effective & Customizable
The standardized production process reduces the manufacturing cost, and the product has high cost performance for bulk procurement. It can also provide customized services according to special project requirements such as special materials and non-standard sizes.
