Hybrid Solution for Grooved Mains and Threaded Branch Connections
- Grooved threaded reducing crosses are designed for piping systems where the main pipeline uses grooved connections, while branch lines require threaded connections.
- This fitting integrates grooved and threaded interfaces into a single component, enabling direct connection between different system types without the need for additional adapters or welding.
- Compared with using separate fittings and adapters, a grooved threaded reducing cross simplifies system configuration and reduces the number of connection points.
- An application example from Singapore involves a retrofit fire protection system where sprinkler heads required threaded connections on an existing grooved main line. By using grooved threaded reducing crosses, the system was upgraded without modifying the main pipeline or introducing additional adapters.
- This product is manufactured from ductile iron, produced through precision casting, followed by coating and thread machining processes to ensure dimensional accuracy and durability.
- Grooved end size range: DN50–DN300
- Threaded end size range: DN15–DN100
Ideal for Retrofit and System Expansion
- Grooved threaded reducing crosses are widely used in retrofit projects, fire protection system upgrades, and building modifications where existing grooved pipelines need to be connected to threaded components.
- This solution allows system expansion without pipe replacement or welding work, improving installation efficiency and reducing system downtime.
- Jianzhi Group manufactures these fittings and supplies products to over 130 countries. The company holds more than 100 national patents and operates advanced production facilities, including DISA automatic molding lines and spectrometric material testing systems.
- Minimum order value is RMB 10,000. Mixed sizes are allowed within a single order. OEM branding and logo marking are available upon request.
