Malleable Iron 90° Elbows

The products are made from malleable cast iron (malleable iron) according to GB/T9440-2010 standards, treated with a high-temperature annealing process. This process eliminates the cracking problems of ordinary cast iron, combining high strength, good toughness, and machinability. They can withstand pressures up to 2.5MPa, operate within a temperature range of -20℃ to 300℃, and are durable and resistant to deformation.

The surface uses an advanced hot-dip galvanizing process to form a dense zinc-iron alloy layer, providing excellent corrosion and rust resistance. This effectively resists erosion from humid and corrosive media, extending the service life of the piping system. The standard precision thread design features smooth, regular threads that conform to multiple international standards, ensuring convenient and efficient installation. Excellent sealing performance effectively eliminates the risk of leakage.

With a complete range of specifications, covering all sizes from DN15 to DN100, and compatible with various pipe diameters such as 4-point and 1-inch, the products feature precise angles (±0.3°), smooth turning, and reduced fluid resistance. They undergo 100% airtightness testing, meet national building water supply and drainage and fire protection standards, are directly sourced from the manufacturer for quality control, and offer comprehensive after-sales service. These are the preferred accessories for pipe turning connections in home decoration, engineering projects, and public facilities.
