YANGSEN TUBE
We develop and produce rolled and drawn precision and profile steel tubes for various industrial sectors using tailored materials and processes.
Airbag
Jansen Steel Tubes produces welded precision steel tubes made of high-tensile materials for airbags. The applications in this area of the auto- motive industry are very sensitive in terms of quality. The quality of the tubes is guaranteed by excellent raw material quality, a very stable welding process in conjunction with comprehensive seam quality testing as well as stringent production and dimensional tolerances. Tubes produced in this way withstand maximum stress when airbags are deployed. Dismantling into several pieces is not permissible (low-temperature impact resistance).
Tube requirements
■ Excellent formabillity
■ Low-temperature ductility
