Kiln Parts
Completed in August on an extremely difficult timeline to maintain and are on schedule. Fabrication and supply of two replacement shell sections, brick supporting ring and feed scoops to suite plant conditions in Kitimat, BC. This job consists of forming and fabricating two tubular shells out of stainless steel. Having stainless castings made, machined and fitted to the shell. Support rings were fabricated to various applications and a set of Vida plate-lined chutes and hoppers were also fabricated to meet the needs of the site conditions.

Expansion Joint
Supply and fabrication of a circular, 316L stainless steel expansion joint. This assembly was 2' tall x 5' wide. Under tight deadlines, KEM managed to ship this expansion joint to a train to get to its final destination in record time

Leach Tank
In July of 2009, KEM completed the design and manufacturing of a Stainless Steel 316L tank, which was scheduled for final assembly in BC. Although the end user was pleased with the quality of work, KEM had a few challenges to overcome to satisfy their needs. The self supporting roof of the 20'x20' vessel has square shapes and massive cut outs that required the use of a 3D software and Finite Element Analysis Program (FEA) to help identify weak/stress points in the tank. The tank was post weld stress relieved using a vibration technology. A computer identifies the stresses in the vessel and then adjusts the vibration accordingly. When complete, a printable record is created of the resonant frequency before and after stress relieving. The 3D software used to design and modify this tank, allowed the client to manipulate and view the vessel from all angles throughout the entire design process. KEM and the client worked closely together to achieve the desired results

Plenum and Frame
This project was the disassembly, re-fabricating the old pieces and re-installation of the plenum and frame for an asphalting machine destined for Africa. This project included new assemblies such as machined heat-treated cylinders support control arms, tarp supports, machined retaining rings, new and upgraded hinges which were all made from stainless steel.

Greenwood Head Tank-GVRD
The GVRD had seen previous tanks that were manufactured by KEM for another phase of this project. GVRD invited us to bid on the contract to design and manufacture the Greenwood Head Tank for the Seymour-Capilano Filtration System project.

Flotation cells
KEM does work as an OEM for a number of clients. Pictured here is a truckload of flotation cells destined for the Kensington Gold project in Alaska. KEM fabricated six of these units and six smaller units within a very tight schedule to meet the delivery requirements for the client.

Expansion Joint & Installation Bands KEM provided a fabricated, circular 4’x4’- 316L stainless steel expansion joint and 2 installation bands for a company in BC, in the spring of 2009. The expansion joint received stress relieving treatment which was between 1900-2050 degrees Fahrenheit. This stress relief changes the composition of the metal and in turn made it better suited to resisting work hardening, weld cracking from high temperature cycles and it is still resistant to an acidic environment. During the heat treatment the expansion joint would expand to its maximum volume and then be “pre-shrunk” so that it does not change shape while performing in its application.

Cascade Mixing Tank
Working closely with our client, a mechanical contractor, KEM engineered a floor and lower shell replacement. By doing the majority of the fitting and welding in house, the contractor was able to minimize the shutdown of the Alberta pulp mills mixing tank
Wastewater Clarifiers
This project was designed to process all the wastewater produced by the City of Jasper to meet better than acceptable discharge standards and was sized to accommodate significant increases in population over the coming years.

Westmark Shaft
Knelson senior fabricators use a unique in-house procedure to repair a chronically failing drive shaft. After multiple failed attempts by several other shops, Knelson was contracted to engineer a lasting solution. The repair strategy included cutting the shaft into two pieces, machining weld preparations and welding a controlled pre and post heating. Continuous cleaning of the weld slag allowed the welder to apply multiple passes without stopping, further enhancing temperature control and weld strength. The shaft has been in service, crack free for two years as of November 2007.
