Malleable iron 90°elbow is with two ends female threads and used to connect the pipes with male threads. It can change the pipeline direction by 90 degree.
This product is a 90° Elbow BSPT Fig 90 made of malleable iron with threaded connection. It is a key pipe fitting used to change the direction of fluid flow in pipeline systems. Its main function is to connect pipes at corners, ensuring smooth directional flow of media such as water, oil, gas, and steam.
Are you looking for a pipe fitting that ensures a tight pipeline system while offering high strength and corrosion resistance? Our malleable iron 90° Elbow BSPT Fig 90 is made of high-quality material through high-temperature annealing forging, resulting in a dense internal structure capable of withstanding working pressures up to 1.6Mpa (16kg) , effectively solving the leakage risk at pipe corners. The surface is treated with uniform anti-rust coating, which is continuous and burr-free, greatly extending its service life.
The product is available in various nominal diameters from DN15 (1/2″) to DN100 (4″) and offers multiple surface treatment options such as natural and yellow-zinc plated. It can be widely used in various working conditions including fire protection, water supply, gas, chemical industry, and plumbing installation.

Fire Protection Systems: Used to connect fire sprinkler branch pipes and fire hydrant risers at turns, suitable for wet or dry fire protection pipe networks.
Commercial Buildings: Applied in air conditioning pipelines, water supply and drainage systems in banks, hotels, and shopping malls.
Industrial Plants: Suitable for industrial pipelines conveying non-strongly corrosive media such as steam, coal gas, and compressed air.
Residential Plumbing: Used for water circuit modification in home decoration, connecting terminals like water heaters and faucets.
Perfectly compatible with steel pipes and black steel pipes.
Must be used with PTFE tape or oiled hemp for thread sealing.
Can be used together with gate valves, globe valves, tees, unions, and other fittings of the same specification.
1.Inspection: Before installation, check the Elbow BSPT Fig 90’s internal and external surfaces for sand holes, cracks, ensure threads are complete without breakage.
2.Cleaning: Remove iron chips and dirt from the pipe ends.
3.Sealing: Wind an appropriate amount of PTFE tape clockwise (recommended 15-20 turns) or apply oiled hemp onto the external thread of the Elbow BSPT Fig 90.
4.Tightening: Screw the Elbow BSPT Fig 90 into the pipe joint by hand, then tighten with a pipe wrench. Use moderate force to avoid cracking the fitting. It’s recommended to secure the pipe near the Elbow BSPT Fig 90 with a pipe clamp to reduce vibration.
1.Inspection Cycle: It is recommended to visually inspect the Elbow BSPT Fig 90 every six months, especially at threaded connections, checking for signs of rust or leakage.
2.Cleaning Method: Wipe the surface dust with a clean, damp cloth. For rust removal, use a wire brush to clean and then apply anti-rust paint.
3.Replacement Cycle: Generally, if there is no mechanical damage or severe corrosion, it can be used for over 10 years. If the Elbow BSPT Fig 90 shows sand holes, deformation, or cracks due to freezing, replace it immediately.
Product List:
Steel Pipe: Match with standard steel pipes of the same specification (e.g., DN25, DN50).
Pipe Hangers/Supports: Provide matching U-bolts, hanger rods for fixing pipeline direction.
Other Fittings: Reducing tees, unions, caps, male nipples.
Sealing Materials: High-quality PTFE tape or liquid pipe sealant.
Combining these with our hot-dip steel pipes and seismic bracing systems builds a sturdy, durable, and code-compliant complete pipeline system. This ensures the pipeline does not detach and fluid delivery is uninterrupted during a fire or emergency.
