Description
BSPT Black FxF 90° Long Bend Malleable Iron Pipe Fittings
When you need reliable pipe fittings for your industrial applications, our BSPT Black FxF 90° Long Bend Malleable Iron Pipe Fittings provide remarkable execution and strength. These specialized pipe connectors are designed for directional stream changes in mechanical channeling frameworks. Not at all like standard short-radius elbows, this component highlights longer clear capability. The double female strung closes adjust to British Standard Pipe Taper specifications. This guarantees pressure-tight seals through prevalent string impedances. You get ideal stream proficiency with negligible weight drop for your basic applications.
Our fittings address particular industry challenges including liquid flow. The long twist geometry essentially decreases grinding turbulence compared to sharp 90-degree elbows. This makes them basic for frameworks requiring tall stream effectiveness and negligible acoustic vibration.



Technical Specifications
Our fittings are fabricated from premium ASTM A197 review pliable press. The tempering prepare changes white cast press into a ferrite network with nodular graphite. This gives tall pliable quality and anticipates fragile disappointment beneath stun loads.
The BSPT threading highlights a 55° string point with 1:16 decrease. This makes a self-sealing component that's predominant to parallel strings in high-pressure applications. The dark oxide coating serves as an amazing base for portray whereas advertising brief erosion resistance.






Key Features
- Superior Stream Elements: Long sweep plan minimizes weight drop and turbulence
- Robust Development: Pliable press gives amazing ductility and strength
- Precision Threading: BSPT strings guarantee leak-free connections
- Versatile Applications: Reasonable for gas, oil, and steam systems
- Quality Coating: Dark wrap up stands up to oxidation and acknowledges paint well
- Industry Compliance: Meets ASME B16.3 and ISO 49 standards

Materials and Surface Treatment
We use high-grade malleable iron that undergoes careful annealing. This process gives our BSPT Black FxF 90° Long Bend Malleable Iron Pipe Fittings their flexibility. They can withstand establishment torque and framework vibration without cracking.
The dark coating gives brief erosion resistance without zinc chipping dangers. This makes them perfect for high-temperature steam applications where galvanized fittings might fail.
Standards and Certifications
Our items comply with universal guidelines counting ASME B16.3 and ISO 49. We keep up strict quality control agreeing to ISO 9001 quality administration framework. Each fitting meets dimensional resistances for exact arrangement in pipe networks.






Application Areas
These fittings exceed expectations in requesting mechanical environments:
Industrial Steam Frameworks: Culminate for condensate return lines where warm cycling happens. The moldable press retains warm stun whereas long twist geometry facilitates condensate flow.
Natural Gas Dispersion: Dark press is the industry standard for gas channeling. BSPT strings give required gas-tight seals for security compliance.
Compressed Discuss Systems: Perfect for car and aviation gathering lines. They keep up weight steadiness whereas withstanding compressor vibration.
Installation Instructions
Always utilize appropriate string sealant consistent with your application. Hand-tighten the fitting to begin with, at that point utilize torques for last fixing. Do not over-torque as this can harm strings. Guarantee legitimate arrangement to anticipate stretch on associated pipes.
Support the pipe framework enough to anticipate intemperate loads on fittings. Take after nearby codes and controls for your particular application.
Packaging and Shipping
We package fittings in protective cartons with anti-rust treatment. Our location in Taigu District gives great coordinations get to. We're fair 40 kilometers from Taiyuan and 30 minutes from the airplane terminal. This guarantees quick, solid conveyance to your extend sites.





Quality Control
Every fitting experiences thorough testing. We perform pneumatic testing at 80-100 PSI submerged to distinguish any porosity spills. String gaging guarantees appropriate BSPT decrease and pitch. We confirm 90-degree points inside strict tolerances.
Material investigation affirms legitimate carbon and silicon substance. This guarantees total tempering has happened. Visual assessment checks for surface smoothness and nonappearance of defects.
OEM and Customization Services
With 26 a long time of casting involvement, we offer comprehensive customization. Our yearly generation capacity comes to 30,000 tons with over 1,000 item determinations. We have 38 proficient specialized faculty prepared to back your particular requirements.
Our offices incorporate 8 medium recurrence electric heaters and progressed machining hardware. This permits us to adjust fittings for your interesting applications.






Frequently Asked Questions
Q: How does the long bend differ from standard 90° elbows?
A: Long bend fittings have larger sweep radius. This significantly reduces friction loss and turbulence compared to short radius elbows.
Q: Can I use these for potable water?
A: No, black malleable iron will rust in oxygenated water. Use galvanized fittings for water applications.
Q: Are BSPT and NPT threads compatible?
A: No, BSPT has 55° thread angle while NPT has 60°. They're not interchangeable.
Q: What's the maximum pressure rating?
A: Standard Class 150 fittings handle 300 PSI at ambient temperature and 150 PSI for saturated steam.
