Better Corrosion Resistance compared to the common 316 Stainless Steel
Less flow resistance
Tube can be cold bent up to 28mm
Increased resistance to stress corrosion cracking
TIG welded for optimum press seal surface
MM Kembla Stainless Steel Tube and KemPress Stainless Steel press fittings are produced using 1.4404/AISI 316L stainless steel material. This material contains at least 2.3% molybdenum and reduced amount of carbon (<0.3%) meaning it has greater corrosion resistance compared to common 316 Stainless Steel.
All stainless steel tubes and fittings are welded using TIG welding technology, providing better control of the fitting and also the press connections. During TIG welding, tubes welded slower and in highly controlled processs which mean less stress on the tube and subsequently diameters up to 28mm can be cold bent. The TIG welding process also means the tube has a strong, mouldable seam that can be easily rolled smooth during the tube making process, creating an optimum press seal surface and reduces flow resistance internally.
A process not done by all manufacturers, all Kembla Stainless Steel fittings and tubes are fully annealed after roll forming and welding which cleans the tube, ensures a stress relieved and corrosion resistant structure and provides a correct and consistent material hardness for press fitting.
