Frequently Asked Questions

What is a long weld flange and where is it used?

A long weld flange features an extended neck that provides extra reinforcement when welded to pipes or vessels. It is commonly used in applications like pressure vessels, heat exchangers, and custom piping systems to handle high pressure and temperature conditions.

Why choose a long weld flange over a standard weld flange?

Long weld flanges offer superior stress distribution, making them ideal for heavy-duty applications. The extended neck ensures better alignment and reduces stress concentration, which is crucial for high-pressure systems and vessels.

What materials are used for long weld flanges?

Long weld flanges are typically made from high-quality materials like stainless steel, carbon steel, and alloy steel. These materials are selected based on the application’s temperature, pressure, and corrosion resistance requirements.
