Welded tubes made of heat-treated sheets

Fields of use

WR Tubes = Wear Resistant Tubes for the delivery of gravel, ballast, stones through tubes into gravel quarries, etc.
HR Tubes = High Temperature Tubes for the delivery of hot materials or use in an environment with increased temperatures up to 590°C and simultaneous resistance against wear.

Description

WR Tubes
WR Tubes are manufactured from hardened wear plates with the Brinell hardness of 450HB. The plates are lasered, trimmed and only welded with a longitudinal seal (single-V weld, MAG through welded). Any possible transverse joints (depending on the material availability) are welded using laser melting without any additional materials.
HR Tubes
HR Tubes are manufactured from pre-hardened TOOLOX mechanical engineering steel sheets. Toolox is available in the formats of TOOLOX 33 (Brinell hardness approx. 300HBW) and Toolox 44 (Brinell hardness approx. 430HBW). In comparison with wear plates, TOOLOX can be used up to 590°C without the mechanical values being majorly changed.

Properties

All tubes are available without flanges, with bolted flanges (DIN2576) or with loose flanges (DIN2642).
Circularity tolerances: +/-2mm
Deflection tolerances: 1mm/m
