Pressure Parts Fabrication from Valmet

Each year our fabrication efforts continue to grow.

We can create most any boiler pressure parts including complete boiler retubes on loose tube bending and tube panels from carbon, alloy, stainless, composite and Inconel.

Other capabilities include complete or partial Superheater and Reheater elements with attachments, economizer bundles, generating banks, tube swages, shotblasting, dissimilar metal welds, straight tubes, and headers.

Keeler Boilers & Replacement Parts

As the exclusive owner of the inventive Keeler boiler drawings and contract files, Valmet Power has all the primitive drawings and contract files for the over 7000 manufactured Keeler boilers. In addition to our in-house stock of standard Keeler fabricated parts and original drawing specs, we have the ability to construct replacement tubes, headers, casing panels, doors, manhole plates, hand hole plates, (both with yokes and gaskets), key caps (with 40+ sizes), key cap pullers, Keeler special shape tiles, standard tile and insulation, soot blower, and more.






A Global Solutions Company You Can Rely On

Finding a resource for custom parts fabrication can be extremely tedious (and difficult) if you don’t know where to look. Power plants, Waste Incineration Plants, Recovery Boiler Plants, Municipalities, and Mining are some of the bigger areas and industries looking to turn waste into energy with these customized parts.

At Valmet, we’re always looking for innovative ways to make your everyday easier at a reasonable cost. Finding high-quality materials at a rational price is a relatable pain point that we work to overcome.

You’ll receive fast turnaround time when it comes to our custom manufacturing and parts fabrication.

Some of our parts and specialty services include:

  • Piping (code & non-code applications)
  • Processing plate, waterjet, laser, plasma
  • Structural parts, feeders, hoppers, conveyors
  • Welding
  • ASME tanks, components, & skids (turnkey)
  • Light structural (beams, service platforms, handrails, etc.)
  • Industrial boiler ducting
  • Tubes (straight, bent, WOL)

Dispose of Your Biosludge with this New & Improved System

Getting rid of secondary sludge, or biosludge, has always been an industry issue bringing forward many problems due to its high water content and the nature of the solids contained. With these drawbacks, transportation and disposal become problematic.

As of recent, field experts are focused on improving what we currently know as traditional disposal methods like landfilling or incineration in the power boiler.

Drawbacks to the traditional approaches include:

  • Offensive odor
  • Water leaching from landfill sites
  • Low thermal efficiency
  • Potential health hazards in handling
  • Overall cost of disposal

With landfills for biomass material now banned in Europe, a new approach was needed and for several mills, this was to incinerate the biosludge in the recovery boiler.

Through a proprietary system, the biosludge is hydrolyzed by mixing it with black liquor and then sent off to the concentrator for disposal in the recovery boiler.

New benefits of this approach include:

  • No offensive odor
  • No handling or transfer of the sludge for transport
  • Higher thermal efficiency by using the multiple effect economy of the evaporators
  • Incineration occurs within the recovery boiler with no real change in operation
  • Lower cost solution internal to the mill operations

Current studies reveal that no significant negative impacts have been experienced in the mills that have taken on incineration of secondary sludge within the recovery boiler.

For more of an in-depth look at the recovery boiler system read our recent white paper. The analysis includes an overview of the secondary sludge hydrolysis process, detailed benefits of hydrolyzing and disposing of sludge in the recovery boiler, user experience, and additional links and information on Valmet Automation products for wastewater handling.

Valmet has over 40 years of experience in the boiler system industry. Our skilled team of industry experts can help improve your handling and disposal of secondary sludge needs.
