Sandvik launches Pressurfect for GDI tubing

Sandvik is launching the next generation of gasoline direct injection (GDI) engine components for lighter, more energy efficient cars with low emission engines. Pressurfect™ is a new range of GDI tubing designed to handle higher operating pressures while delivering exceptional weight savings of up to 40%. The range offers substantial design and operational benefits with the ability to handle operational pressures over 350bar.

Designed for stronger, safer handling of fuel pressures with no pitting or cracking, standard Pressurfect is an austenitic chromium nickel steel designed for fuel rails and fuel lines. Offering lightweight duplex stainless steel tubing with superior mechanical strength, Pressurfect XP enables the reduction of tube wall thicknesses by up to 40% with the ability to handle the same high operating pressures as thicker tubes. Both Sandvik materials offer higher corrosion resistance and the ability to handle the increasing operational pressure levels being demanded for GDI fuel systems. Optimised for safe, reliable operation, as well as drilling and turning, when used in fuel lines they are easier to bend and shape as required.
