Materials and Surface Treatment
We fabricate these fittings from premium moldable press that gives extraordinary ductility compared to standard cast press. The ferritic structure guarantees solid execution beneath warm cycling conditions.
The dark wrap up comprises of either dark oxide coating or defensive enamel. This treatment avoids oxidation amid capacity whereas keeping up string keenness. The wrap up too gives great base arrangement for extra defensive coatings if required.
Standards and Certifications
Our NPT Black Flange Pipe Fittings comply with industry benchmarks counting ASME B16.3 for measurements and ASTM A197 for fabric properties. We keep up strict quality control through ISO9001 certified fabricating processes.
All items experience thorough weight testing and dimensional confirmation some time recently shipping. Our quality framework guarantees reliable execution over each batch.
Application Areas
Industrial Gas Frameworks: Culminate for normal gas and propane conveyance where zinc-flaking from galvanized fittings seem cause problems.
Steam Warming: Perfect for moo to medium weight steam frameworks in commercial and regulation buildings.
Fire Assurance: Fundamental for hydrostatic testing of sprinkler frameworks and brief line sealing.
Heavy Apparatus: Utilized in pressure driven return lines and gear deplete ports where flotsam and jetsam resistance matters.
Chemical Handling: Appropriate for non-corrosive chemical applications requiring detachable connections.
Installation Instructions
Clean all strings altogether some time recently establishment. Apply fitting string sealant (pipe dope or PTFE tape) to male strings as it were. Hand-start the fitting to anticipate cross-threading.
Use legitimate torques on the rib surfaces, not the strings. Fix until the strings lock in completely additionally 1-3 extra turns. Maintain a strategic distance from over-torquing which can harm the fitting or mating component.
For gas applications, perform spill testing with endorsed discovery arrangements after installation.

Frequently Asked Questions
Q: What's the difference between NPT and BSPT threads?
A: NPT uses a 60-degree thread angle with 3/4" per foot taper. BSPT has a 55-degree angle. Both are available in our product line.
Q: Can these fittings handle steam applications?
A: Yes, they're rated for temperatures up to 366°F for saturated steam at reduced pressures.
Q: What thread sealant should I use?
A: For gas: approved pipe dope. For water/steam: PTFE tape or liquid sealant. Never use tape on gas lines.
Q: How do I prevent galvanic corrosion?
A: Use our black iron fittings with black steel pipe. Avoid mixing with galvanized components in the same system.
