Our Factory



Technical Specifications
These fittings are made to meet exacting industry guidelines. The moldable press development experiences thorough toughening forms, changing over white cast press into a pliable framework that withstands warm stun and physical affect. The NPT threading takes after ASME B1.20.1 details with a 1:16 decrease proportion, guaranteeing leak-proof fixing when legitimately introduced with fitting string compounds.

| Pressure Rating | Class 150 (300 PSI at -20°F to 150°F) |
| Steam Rating | 150 PSI at 366°F (saturated steam) |
| Tensile Strength | Minimum 200 MPa (29,000 psi) |
| Material | Malleable Iron per ASTM A197 |
| Angle Tolerance | ±1° deviation maximum |
| Finish | Black anti-rust oil coating |
Key Features
Your ventures advantage from a few inventive plan components. The square confront fortification avoids bell-mouthing amid fixing, a basic advantage over thin-walled choices. The 45-degree point decreases weight drop altogether compared to 90-degree elbows, protecting pressure driven vitality in your systems.
The dark wrap up encourages extra portray for mechanical coding or tasteful purposes. String exactness guarantees legitimate fixing without intemperate torque prerequisites. The moldable press composition permits warm development and compression without breaking, making these fittings idealize for temperature-cycling applications.

Materials and Surface Treatment
We utilize high-grade pliable press acclimating to ASTM A197 benchmarks. The toughening prepare changes over the base fabric into a pliable framework with great affect resistance. The dark wrap up comprises of anti-rust oil or matte finish, giving brief erosion assurance and simple distinguishing proof of non-potable applications.
Standards and Certifications
Our fabricating takes after strict quality conventions counting ASME B16.3 and ASTM A197 compliance. Each clump experiences metallographic investigation to confirm total malleabilization. String exactness meets ASME B1.20.1 details for solid fixing performance.






Application Areas
These fittings exceed expectations in mechanical LPG and common gas dispersion frameworks where vigorous development is basic. High-pressure steam warming frameworks advantage from the warm cycling resistance of pliable press development. Fire concealment frameworks and uncovered mechanical plumbing establishments utilize the NPT Black Square Face 45° Elbow Pipe Fittings for their heavy-duty rating and visual inspection advantages.
Installation Instructions
Always utilize suitable string sealant or PTFE tape with these fittings. The NPT decrease strings require fixing compound to fill helical spill ways. Hand-tighten to begin with, at that point utilize torques on the square confront for last situating. Dodge over-tightening which can harm the strings or split the fitting body.
Packaging and Shipping
We bundle fittings in defensive cartons with anti-corrosion paper. Bulk orders dispatch in wooden cartons for greatest security. Standard conveyance time is 15-20 trade days for stock sizes. Custom orders may require extra lead time depending on specifications.





Quality Control
Every fitting experiences thorough testing counting string gage confirmation and pneumatic seal testing at 0.6 MPa. Point exactness assessment guarantees exact 45-degree geometry. Our quality group particularly looks at square confront ranges for casting absconds that may meddled with installation.
OEM and Customization Services
We offer custom measuring and uncommon wraps up for expansive orders. Our building group can alter measurements to meet your particular prerequisites. Least arrange amounts apply for custom details. Contact us for nitty gritty customization capabilities.






Frequently Asked Questions
Q: Can these fittings be used for potable water systems?
A: No. Black iron fittings will corrode in oxygenated water and contaminate the supply. Use galvanized fittings for water applications.
Q: What's the advantage of square face over round bead design?
A: Square faces add structural mass at the weakest point, preventing splitting under high torque and providing better wrench grip.
Q: Do I need thread sealant?
A: Yes. NPT threads require PTFE tape or pipe dope for proper sealing and installation lubrication.
