Galvanized malleable iron 90-degree elbows with internal and external threads are efficient fittings for achieving right-angle turns and flexibly changing connection methods in piping systems. This product is precision cast from high-quality malleable cast iron (malleable iron) and treated with a high-temperature hot-dip galvanizing process, forming a robust zinc-iron alloy protective layer on the surface. It possesses excellent mechanical strength and long-term corrosion resistance, adapting to various complex environmental requirements.
Core Features:
Bidirectional Flexible Connection:One end is a standard external thread (male thread), and the other end is an internal thread (female thread), allowing direct connection to external threaded pipe fittings or quick docking with internal threaded interfaces, greatly improving the flexibility and efficiency of pipeline layout.
Stable Right-Angle Turn: The 90-degree flow channel is optimized for smooth turning while ensuring a compact structure, effectively saving installation space and reducing fluid impact.
Reliable Sealing and Durability: Precision-machined tapered pipe threads ensure a tight connection, and with the help of sealing materials, a leak-proof seal can be achieved; the malleable iron base material and galvanized layer together ensure long-term pressure resistance and corrosion resistance.
Specifications and Applications: Available in common diameters from DN15 (1/2") to DN150 (6"), strictly conforming to national pipe thread standards. Widely used in water supply, drainage, HVAC, fire protection, and industrial piping systems where right-angle turns and different thread interface conversions are required, especially suitable for equipment interface connections, pipeline maintenance, and renovation.
Reasons for Selection: The galvanized malleable iron internal and external thread 90-degree elbow features an integrated bidirectional interface design, simplifying installation steps and solving complex connection problems. It is a practical choice for improving construction efficiency and optimizing pipeline layout.
