Key Features & Advantages
Safe Installation in Hazardous Areas
Your security comes to begin with. These spines dispense with welding dangers in dynamic refineries, chemical capacity zones, and gas offices where flashes might cause disastrous incidents.
Rapid Assembly Process
You can total establishments rapidly without certified welders or costly welding gear. This altogether diminishes your extend timelines and labor costs.
Easy Maintenance Access
When you require framework adjustments or cleaning, basically unscrew the association. This openness demonstrates priceless for frameworks requiring visit inside maintenance.
No Heat Treatment Required
Skip the time-consuming post-weld warm treatment prepare completely. Your venture plans remain on track without compromising fabric properties.
Coating Protection
Threading jam your pipe's defensive coating, not at all like welding which harms galvanized or forte coatings. This keeps up long-term erosion resistance.

FAQ
Q: Can flanges handle high-pressure applications?
A: Absolutely. Our product are available in ratings up to Class 2500, though they work best in smaller diameter lines under 4 inches.
Q: Do I need seal welding after installation?
A: Not typically. Quality thread sealant or PTFE tape provides adequate sealing for most applications, preserving the easy disassembly advantage.
Q: What's the difference between NPT and BSPT threads?
A: NPT uses 60-degree thread angles (American standard), while BSPT uses 55-degree angles (British standard). They're not interchangeable.
Q: Why are flanges limited to smaller pipes?
A: Larger diameter threading becomes mechanically challenging and less reliable. Welding provides better strength for pipes over 4 inches.
Q: Can I use these on thin-walled pipes?
A: No. You need sufficient wall thickness (typically Schedule 40 or 80) to cut threads without weakening the pipe structure.
