Tube Alignment Castings
Maintaining Pendant Tube Alignment
Pendent tube misalignment is one of the leading causes of tube failures in boilers. Due to the location of these failures, a simple fix is never simple. The P&I patented Thru-Bolt tube alignment castings reduce the chances of tube failures due to misalignment.
Patented Thru-Bolt Tube Alignment Castings
P&I Proprietary Alloy Material
PI-2000 | Similar to a HH Stainless, this proprietary nickel chrome alloy gives superior heat resistance and creep strength up to 2000°F gas temperatures. The elevated carbon results in good erosion resistance.
PI-2200 | Similar to HK Stainless, this proprietary alloy is similar to the PI-2000 but rated for temperatures up to 2200°F.
PI-2400 | A proprietary nickel chrome alloys with 14-16% cobalt alloy for use in temperatures up to 2400°F.
PI-2450 | A proprietary nickel chrome alloy with 4.5-6% tungsten alloy for use in temperatures over 2450°F. The added tungsten provides excellent abrasion resistance.
Inconel 600 Alloy | This nonproprietary nickel-chromium alloy is designed for locations subject to high oxidization and greater than 2200°F temperatures.
