What does '1.5D' mean for the bend radius?

The '1.5D' refers to the bend radius being 1.5 times the tube's outer diameter. For this 1.625-inch tube, it means the centerline radius of the bend is approximately 2.4 inches.

Why is mandrel bending important for exhaust tubing?

Mandrel bending uses a supportive internal mandrel during the bending process. This prevents the tube walls from collapsing or kinking, ensuring a smooth, consistent inner diameter for optimal exhaust flow and structural integrity.

What is this tubing typically used for?

This type of tubing is commonly used in custom exhaust system fabrication, including building headers, downpipes, or custom exhaust routing where specific bends and diameters are required.

About this part

Product Details

This 1.625-inch diameter tubing from Stainless Bros features a tight 1.5D (1.5 times the tube diameter) bend radius, resulting in a 2.4-inch centerline radius. The 180-degree bend is formed using a mandrel process, which helps maintain the tube's shape and prevents it from collapsing or kinking during the bending process. This is crucial for exhaust systems where smooth airflow is important.

The tubing itself is constructed from durable steel, suitable for custom exhaust fabrication projects. Each leg of the bend measures 6 inches, providing ample length for connecting to other exhaust components or routing the system. The mandrel bending ensures consistent wall thickness throughout the bend, which is a key factor for weldability and overall system integrity.
