TECH SHEET - WELDING

REDOX products are specially treated to resist the formation of scale on the I.D. of the pipe when it is welded. To achieve these results you must follow a few simple steps:

1. The pipe must be cut dry. Oil- or water-based lubricants will interfere and cause scale formation.

2. During welding one end of the pipe must be sealed at all times. This prevents a “stovepipe” effect. Should a “stovepipe” effect occur, it will bring oxygen into contact with the hot I.D. of the pipe and cause scale formation.

3. Extreme care must be taken so that undercutting does not occur when welding. Undercutting will cause significant loss of working pressure. On a 1.00" Schedule 80 A106 B Seamless pipe the loss of just 1/16" due to undercutting will reduce the safe working pressure by 1672#. Appropriate AWS procedures should be called out for all welding.

4. Anti-splatter compounds should be avoided if they contain chlorinated solvents such as “Tri-Chlor.” Chlorinated solvents have been directly linked to corrosion in steel.
