Aerospace Bending Tubes and Assembly (Precision Tube Bending: PTB)
We exhibit products from Precision Tube Bending (PTB), California, USA. Founded in 1957, PTB has been delivering their products to many renowned aerospace and defense programs. Primarily, PTB processes tubes and supplies various types of tubes for the Artemis Project, including launch vehicles, crewed spacecraft, and rocket engines. Specifically, PTB provides main tubes for the BE-4 and RS-25 rocket engines. PTB handles a wide range of materials and processes, including bending, beading, flaring, welding, insulation treatment, and surface treatment. They can process tube diameters from 1/32” to 10” and also work with double-walled tubes. Additionally, PTB supports customers’ tubing integration through OEM program management. PTB's advantage lies in their ability to process larger diameter tubes with thin walls, even with a bending radius of less than 1D. PTB is NADCAP certified, allowing them to perform various types of welding, such as TIG, in-house.
