Recommended Repair Procedures
Molten Metal Transfer Piping
 

 
  1. Remove metal residue and remainder of original refractory liner.
  2. Inspect to assure that residue of refractory cement, if any, is not sufficient to obstruct insertion of new liner. A wire brush, putty knife or similar tool can be used.
  3. Place steel pipe or steel elbow in rigid fixture such as a common table vise. Straight sections of steel pipe should be placed approximately horizontal and elbows should be placed as shown above. Do not clamp tight enough to distort pipe.
  4. Insert dry ceramic liner into pipe or elbow to assure that liner can be installed with minimum effort. Excessive clearance between liner and pipe is preferable to a tight fit since liner will swell during Step 6. Course sandpaper can be used to remove high spots in liner or to reduce liner O.D.
  5. Stir supply of H.T.S. ceramic cement to consistent thickness. Small amounts of clean water may be added and thoroughly stirred to a good working consistency.
  6. Place a clean large neck container directly under the entrance end of the steel elbow or steel extension to be relined. Insert this end into the steel pipe or elbow and insert liner completely into the steel while pouring H.T.S. ceramic cement around the liner as it enters the steel. Position the liner with equal amounts of excess protruding from both ends.
  7. Allow relined pipe to dry thoroughly, using a hot or warm area if available.
  8. Saw off protruding liner flush with flanges and paint sawed surfaces with H.T.S. ceramic cement. Work H.T.S. ceramic cement into any void between liner and steel pipe.
  9. Allow finished assembly to dry thoroughly using an oven or hot area if available. Caution: Moisture and molten metal are an extreme hazard! Assembled pipe must be dry and preferably warm to the touch prior to use for molten metal transfer.
