Perfecting The Process Extrusion
vs. Welding

Wondering how extrusion can result in better integrity for your pipeline or processing facility?

Extrusion is a process by which the metal is carefully reshaped using mechanical pressure. This can be done through either a hot or cold process, often using dies to help shape the component to desired specifications. This method of metalworking enables manufacturers to meet engineering and code requirements with zero weldings whatsoever.

Conventionally welded components are a mainstay in the industry. But in products such as branch tees, the WeldFit technique enables you to eliminate a stress riser which can deliver additional benefits. In fact, the extrusion process can deliver a number of technical and logistical advantages when compared to conventionally welded components. All while meeting codes such as ASME B31.3, B31.4, and B31.8.

Streamlined Inspection Process

Branch tees created using extrusion require no run-to-branch weld, which means no need to perform a radiographic inspection of this component section.

Superior Component Strength

Extruded components are oftentimes able to withstand greater external loads when compared to branch weld components, and can also offer greater longevity.

More Design Flexibility

Extruded components offer more flexibility, as a rule, enabling engineers greater freedom to optimize the overall system and component design.

Less Weight on the Line

Because no external reinforcement pad is required, extruded components have the potential to slash the weight of a component and, at scale, the entire line.

More Project Confidence

Extruded components don’t run the risk of being kicked back in the field because of a failed branch weld inspection, delaying commissioning, and creating other problems.
