Excel-Lap ®
| Precision fabricated shiplap on all butt and longitudinal
joints of pipecovering, fittings and curved sidewall segments. The long edges
have 'key type' joint; while the ends have a 'male/female' connection. |
Excel-Lap ®
Double Layer insulation is achieved in one application.
This reduces labor required to compete the project.
Precut joints define
only one method of installation application, this assuring that all joints in
your cold system are 'staggered' . Inter-locking joints eliminate through
joints to the pipe upon installation. Risk of moisture, frost or ice build-up
is reduced. Life of sealant is prolonged. |
Excel-Lap ®
| Fittings tend to present the greatest problem area of any
installation. The shiplap on the throat, heel and ends insure against thermal
breaks to the pipe. Extol's two piece fittings conform to the shape of the
fitting AND the metal or PVC cover. | |

Practices
Fabrication Tolerances = ASTM C450 &
C585 |
Excel-Lap ®
| typically any pipeline system which operates at a
temperature that requires double layer insulation is a candidate for Excel-Lap.
Long, straight runs of piping* provide the greatest economics benefit durning
installation.
* Maintain proper expansion/contraction joint spacing per
manufacturers recommendation per material. |
Limitations
Lines which cycle on a regular basis from hot to cold
should maintain double layer insulation construction to accommodate expansion
and contraction coefficients of the insulation material and substrate.
Minimum
wall thickness of insulation is 2"; and the maximum is 3" thick.
Cryogenic
systems are excluded. | |
