The Model Elbow Fig 120 BSPT is a malleable iron 45-degree Elbow Fig 120 BSPTwith female threaded connections on both ends. It is designed to change the direction of piping by 45 degrees, allowing for smoother flow transitions and the ability to navigate around structural obstacles in a piping system.
Are you looking for a reliable way to achieve a slight directional change in your fire protection or industrial piping system while maintaining full flow capacity and system integrity?
The Elbow Fig 120 BSPT elbows are manufactured from high-quality malleable iron, offering excellent ductility and impact resistance. The 45-degree angle reduces turbulence and pressure drop compared to sharper 90-degree bends, making it ideal for systems where flow efficiency is critical.
Offered in a variety of sizes from 1/2″ to 4″, these fittings are best suited for use in fire protection systems (per NFPA standards), commercial and industrial plumbing, compressed air lines, and HVAC applications.
Malleable iron 45° elbow is with two ends female threads and used to connect the pipes with male thread. It can change the pipeline direction by 45 degree.
Expected Use:
The Elbow Fig 120 BSPT female Elbow Fig 120 BSPTis designed for general purpose piping applications where a 45-degree directional change is required. Specific applications include:
Fire Protection Systems: Branch line and main line connections in wet and dry pipe sprinkler systems, especially where obstacles require a gentler change of direction (meets NFPA 13 requirements).
Commercial Buildings: Water supply distribution, HVAC systems, and plumbing in hotels, hospitals, shopping malls, and offices.
Industrial Facilities: Compressed air lines, cooling water circuits, and low-pressure process piping in chemical plants and factories.
Residential Plumbing: Potable water lines and heating systems where 45-degree turns reduce stress on pipes and improve flow.
It is suitable for conveying water, oil, gas, and air within its designated pressure and temperature ratings.
Compatibility：
Pipes: Compatible with Schedule 40 threaded steel pipe (black or galvanized) as per ASTM A53.
Fittings: Works seamlessly with other threaded fittings from the same series, such as tees (MI-TEE), couplings (MI-CPL), and unions (MI-UN).
Thread Sealants: Compatible with PTFE tape, pipe joint compound (pipe dope), or other approved thread sealants for leak-proof joints.
Fire Protection Valves: Can be directly connected to threaded gate valves, check valves, and alarm valves.
Installation Guide：
1.Preparation: Inspect the fitting for any damage, cracks, or debris in the threads. Clean threads if necessary. Select the correct size of pipe and fitting.
2.Apply Sealant: Apply an appropriate thread sealant (e.g., PTFE tape or pipe joint compound) to the male pipe threads. Wrap the tape in the direction of the threads (clockwise).
3.Initial Assembly: Hand-tighten the fitting onto the pipe until snug.
4.Final Tightening: Use appropriate pipe wrenches to complete the tightening. Hold the fitting body with one wrench and turn the pipe with another, or vice versa. Tighten to the manufacturer’s recommended torque, ensuring the joint is wrench-tight but not over-tightened to avoid stressing the fitting.
5.Alignment: For 45° elbows, ensure the desired direction is achieved before final tightening.
Maintenance Tips：
① Inspection Cycle: Conduct quarterly visual inspections, especially in fire protection systems. Check for signs of corrosion, leakage at thread joints, physical damage (cracks, deformation), or buildup of debris.
② Cleaning Method: Keep the exterior clean to allow for easy inspection. Use a clean, dry cloth to wipe the surface. In corrosive environments, consider applying a protective coating if required by site specifications. Do not use sharp tools that could damage the fitting or its protective galvanized layer.
③ Replacement Cycle: In fire systems, fittings should be replaced immediately if any damage or leakage is found. While malleable iron fittings are durable, the entire system should be evaluated after any major fire event or if the pipe schedule requires replacement due to age or corrosion.
Recommendation: Combined with MI series malleable iron fittings and fire sprinkler heads, it can build an efficient and stable fire piping system to maximize overall protection.
. Can you supply OEM?
OEM is available. We can customize the packaging and casting markings based on your MOQ and brand requirements.
. What’s the MOQ?
MOQ is 50 pieces for standard sizes (1/2″ to 2″). For less-than-MOQ orders or sample requests, please contact our sales team for feasibility.
