In industrial piping systems, the quality of each connection directly affects performance, safety, and maintenance costs. One of the most reliable solutions for demanding projects is the Sprayed Butt Welded Flange with Neck.

What Is a Sprayed Butt Welded Flange with Neck?

This type of flange is designed with a long tapered neck that is welded directly to the pipe. The “sprayed” finish provides additional surface protection against corrosion, extending service life in harsh environments such as chemical plants, offshore platforms, and high-temperature pipelines.

Compared with ordinary flat flanges, a butt welded flange with neck ensures:

Strong load-bearing capacity – stress is evenly distributed between pipe and flange.

Superior sealing performance – less risk of leakage under high pressure.

Resistance to vibration and fatigue – suitable for dynamic operating conditions.

Extended lifespan – reliable even under cyclic loading and thermal expansion.

Where Are They Used?

Sprayed butt welded flanges with neck are widely applied in industries where safety and reliability are non-negotiable:

Oil & Gas pipelines – long-distance transmission of crude oil and natural gas.

Petrochemical plants – resistant to corrosive fluids and high pressure.

Power generation – used in boilers, steam lines, and turbine systems.

Marine & offshore engineering – withstand seawater corrosion and vibration.

High-pressure test lines – ensuring secure sealing during critical operations.

Comparison With Other Flange Types

Choosing the right flange often depends on the project requirements. While sprayed butt welded flanges with neck are excellent for high-pressure and high-temperature service, you may also consider:

Slip On Flanges – simple installation, cost-effective for low-pressure pipelines.

Blind Flanges – used to block pipeline ends or perform pressure tests.

Socket Weld Flanges – ideal for small-diameter, high-pressure applications.

Each flange type serves a unique purpose. By linking different solutions together, you can design a system that balances cost, safety, and performance.
