Tube Products Ltd. has announced the availability of Tru-Wel aluminized perforated steel tube for exhaust pipes which has a much longer service life than a mild-steel tube and reduces the number of production operations involved in the manufacture of silencers. It has a high resistance to corrosion, a h[gh torsional strength and good concentricity in addition to a low weight.
All sizes of tube in the.li-in. to 2in. outside diameter range, commonly used for exhaust silencers, can be produced in 16 and 18 s.w.g. wall thicknesses. A typical perforation pattern is diameter holes at Lin. staggered pitch, but alternative patterns can be made available as required.
