In-Plant Factory Recovery Services

Compositech offers two approaches to disc filter sector recovering:

• In-plant sector recovery tied to scheduled facility turn-arounds
• Compositech factory recovering from the customer's backup spares

In-Plant Sector Recovery Service

Compositech recommends in-plant recovering when a facility chooses to change several rows of sectors regularly as part of a PM schedule. While on-site, Compositech's crew provides the following services:

• Remove a predetermined number of sectors from the Saveall
• Remove the sector cover
• Pressure clean the sectors to remove residue and fiber build-up
• Inspect each sector for broken welds, stress cracks, or other damage
• Complete minor weld repairs as indicated and approved
• Install new covers and steam sectors, so the covers shrink to fit
• Re-install recovered sectors in Saveall with new acid resistant gaskets
• Inspect and adjust all clamps, mounting bolts, etc.

While Compositech's crew is at your plant, they also inspect all remaining sectors not scheduled for recover and replace any damaged covers. This preventive maintenance sector recover method provides for a complete scheduled recover of all sectors and minimizes the likelihood of operating the Saveall at less than peak efficiency due to sector problems. We provide all the labor, equipment, tools, and transportation and we always bring along a supply of small parts that may need replacement. Our crew works to insure no delays in completing the work within your schedule and we have a Compositech technician on-site until the plant restarts and the filter is fully operable.

Factory Sector Recover Service

Factory recovery services are preferred by our customers who have spare sectors in stock and choose to change out sectors when visible damage has occurred. This method results in a cleaner sector body that has been more thoroughly inspected for stress cracks. The cover is installed at our factory using a heat knife to cut the cover to size and using ultrasonic welding to provide a smoother surface and more consistent fit while eliminating stitching and zippers.

Compositech provides the following complete sector rebuild services:

• Remove the sector covers
• Pressure clean the sectors to remove residue and fiber build-up
• Shot blast clean each sector to remove all built up residue
• Inspect each sector for broken welds, stress cracks, or other damage
• Complete minor weld repairs as indicated
• Install new covers and steam sectors so the covers shrink to fit
• Install acid resistant gaskets on the neck of each sector
• Replace hardware items - threaded inserts, bag clamps, rope ties, etc.

Added freight costs for shipping to Compositech's factory are offset by the efficiencies in this type of cover installation if a minimum of 36 sectors are available for each shipment. Our shipping department arranges the pick-up and return of sectors. Just let us know they are ready for transport and we will handle the rest.
