How Screwed Flanges Work
Screwed (threaded) flanges connect by screwing directly onto externally threaded pipe ends—creating a tight seal without welding.
Because welding is not necessary, they can be deployed safely in hazardous or explosive environments (Ex zones) where ignition risk must be minimized.
When additional sealing strength is needed, a seal weld may be added, though this reduces ease of disassembly.
Benefits of Screwed Flanges
- Easy Installation & Maintenance: No special welding permits; ideal where welding is difficult or restricted.
- Cost‑Effective: Saves on labor and downtime, especially in low‑pressure systems.
- Reliable Leak‑Sealing: Threaded connection provides good sealing performance.
- Versatile Material Compatibility: Suitable across materials and pipe types.
- Rotational Adjustment: Some versions (e.g. lap joint/flangettes) allow alignment under bolt‑hole rotation.
Common Uses
- Plumbing & Small‑Diameter Piping: Where welding isn’t practical.
- Oil & Gas Equipment: And hexane or fuel storage tanks in explosive environments.
- Chemical & Pharmaceutical Plants: For fast assembly/disassembly.
- Water Treatment & Power Plants: Used in piping, valves, pressure vessels.
- Low‑temperature or Low‑pressure Piping Systems: Where heavy-duty weld neck flanges are not necessary.
FAQs
Q1: What is a screwed flange?
A screwed flange, also known as a threaded flange, attaches to a pipe using male‑female threads instead of welding, suitable for easy assembly and disassembly.
Q2: In which material grades are these flanges available?
Carbon steel, stainless steel (e.g. ASTM A182 F304, F316), alloy steel, duplex and nickel alloys as per ASME/ANSI standards.
Q3: What sizes and pressure classes do you supply?
Sizes from ½″ to 48″, pressure classes from 150# up to 2500# or PN6 to PN64, meeting ASME B16.5/B16.47, BS/DIN standards.
Q4: Are these flanges suitable for high‑temperature or high‑pressure service?
Primarily designed for low-to-medium pressure systems; seal welds can enhance integrity but are not a substitute for weld neck flanges in high‑pressure applications.
Q5: How do I order or get a quote?
