Threaded Flange
At Metrade, we offer a full range of high-quality threaded flanges that create secure, high-integrity connections in piping systems where welding isn’t the preferred option. These fittings work reliably in hazardous environments or locations with installation limits, giving you a safe and efficient way to form strong joints without heat-based processes. Our experts test every threaded flange to confirm strength, accuracy, and dependable function.
Our team applies strict precision standards and maintains consistent production quality to support long-term system performance. We use premium materials such as carbon steel, stainless steel, and alloy steel to match the needs of different applications. With durable construction and hands-on technical support, our products help you protect system integrity, improve efficiency, and meet the demands of challenging industrial operations.

A threaded flange is a type of flange that features internal threads, allowing it to be screwed directly onto a pipe without the need for welding. This makes it especially suitable for low-pressure, non-critical applications or systems where welding is not feasible, such as in explosive environments. Threaded flanges are typically used with pipes that have external threads and are ideal for small-diameter piping systems. They are available in various materials, including stainless steel, carbon steel, and alloy steel, to suit different industrial requirements and environmental conditions. Commonly used in industries such as plumbing, water treatment, gas distribution, and chemical processing, threaded flanges offer the advantage of easy installation, removal, and maintenance while providing a reliable connection when welding is not an option.
