Basically it consists of easy-to-weld mild steel tubes which have been internally welded with TeroMaTec 4666 alloy which maintains the exceptional wear resistance of our well known 4666 CastoDur Diamond Plates. Furthermore, CastoTube avoids expensive forming operations of flat plate into tube.

CastTubes offer many advantages:
■ Highly cost effective
■ Absence of harmful linear weld joints
■ Exceptional wear resistance
■ Perfect round cross section
■ Spiral welding minimises distortion
■ Lightweight for handling
■ Easy-to-join by welding or mechanical means.

Controlled cooling during the manufacturing process produces densely dispersed hard phases. These are vertically oriented to provide superior wear resistance as compared to conventional weld coating.

CastoTubes are engineered for exceptional wear resistance as illustrated by the laboratory abrasion wear test data. This performance results from:

■ Ultra-hard phases anchored in a tough matrix. Their hardness is typically 2-3 times higher than the most abrasive media used in industrial processes.
■ Unique geometry of hard phases achieved by controlled cooling of weld solidification kinetics. These tend to nucleate as a dispersion between other needle shaped phases which are vertically oriented and firmly anchored within the matrix. This prevents premature "washing out" of the hard phases from the "softer" matrix by wear.
