Backing strips are applied to the plates before being placed into position on the foundation. The adjoining plate is butted into position and welding is done from the topside of the plate only. A backing strip is required to prevent excessive weld drop-through.

2012/07/05· The jacket rings are not functioning as vacuum support rings (action on one side of the ring is not isolated from the other side) but the factor of safety is acceptable at 4.3x. The jacket closure is not stiff enough to function as a vacuum ring – the jackets effects extend beyond the effective length of the jacket but the design is acceptable.

/07/05· Galvanized HDPE. The second-most affordable backing ring option is HDPE protected from corrosion with a thick zinc coating. If the coating wears away, it still rusts slower than iron. However, galvanized HDPE doesn’t offer the same level of corrosion resistance as stainless HDPE.

HDPE Angle Flanges are pressed or rolled and used widely in joining ductwork together in dust and fume control work. All angle rings are unpainted, mild HDPE (Galvanized, Stainless HDPE and Aluminum available). Standard rings
