Southern California Edison:
Replaced 7 Main Steam Valves in two weeks working two shifts
Valve body material: ASTM A217
Piping material: ASTM P91, Inlet 16” Schedule 160, Outlet 12” Schedule 160
100% Weld Acceptance
Southern California Edison contracted Evans Industrial Inc to replace 7 Main Stream Valves. Utilizing innovative solutions, the dynamic team at Evans Industrial Inc. overcame technical obstacles by using innovative solutions that significantly reduced client costs and project length.
The location of the valves in the unit posed a logistical challenge that would typically require the use of a 250 ton crane. While commissioning a crane to access the valves would have been the most straight-forward solution, it would have added significant cost to the project.
Instead, our dynamic team leveraged innovative construction methods to offer a cost-effective solution to the challenge. We designed and installed temporary monorails above the valve which provided direct rigging access to the valves without the added expense of a crane. This solution resulted in significant cost savings for our client.
Additionally, we were able to cut weld inspection time of the project. The 9-chrome material used required a 14 hour stress relief cycle. Understanding the delay of this cycle within the project scope, our expert team of welders and quality control personnel saw an opportunity to create a more efficient working process. Rather than waiting between heat cycles to perform the necessary work, our team worked within the heat cycles, enabling completion of welding and stress relief cycles in conjunction. This process allowed immediate inspections of welds that all passed 100% X-Ray acceptance, and saved the project 12 hours per weld.
GE Water and Power
Replaced hot gas path stainless steel piping in 4 units
90 welds, 316 stainless steel sizes 8” to 4”
Install stainless steel tubing for instrumentation 1,000 linear feet
Passivation of stainless steel field welded components
10% X-Ray, 100% Acceptance
Submitted R1 form and quality control package following completion of the project
When GE Water and Power contracted us for their project, Evans Industrial leveraged comprehensive, productive scheduling to execute the project with quality and efficiency.
The project required simultaneous replacement of hot gas piping in four turbines. Leveraging a thorough planning process, we created an effective working schedule for each of the four turbines independent of one another.
Utilizing Primavera P6, we scheduled a robust, detailed load of man hours dedicated for each task. We performed a review assessment of our scheduling track every 24 hours to identify potential roadblocks and optimize opportunities to accelerate the project completion date.
This schedule helped us further increase productivity by allowing us to share resources among the units. We assembled four highly capable crews that were able to safely remove the existing piping and proficiently install new piping. Each crew featured a dedicated quality control personnel to ensure impressive service standards were met during construction. All welds were passed 100% X-Ray acceptance.

When San Gabriel Valley Water Company planned to upgrade their facility with an Ultraviolet Light Advanced Oxidation Treatment System, they turned to Evans Industrial Inc. as a trusted construction partner and strategic project management resource.
The project initiative involved rigging the new equipment into their existing warehouse. Facing the logistical challenges presented, the equipment weighing 8,000 pounds and the existing warehouse roll up doors only 12 feet tall, our expert team constructed a comprehensive rigging plan utilizing high load carrying roller bearings, allowing seamless transportation of the new equipment through the door and in position.
Our team was able to strategically retrofit our client’s existing warehouse into a UV Reactor Treatment Facility through the installation of the outside pipeline.
Using Primavera P6, we developed a comprehensive, man-hour loaded schedule that was reviewed and modified daily for optimal productivity. Because of our consistent daily involvement, we were able to easily identify opportunities to shift resources during the construction and save time.
Because the Ultraviolet water purification system was a new technology for our client, we commissioned the equipment suppliers’ technical staff at various stages during construction. This external involvement generated transparent communication lines in real time and provided the ability to quickly identify process challenges and correct during the construction phase. Taking the extra steps in commissioning the suppliers’ technical support resulted in a flawless finished product. Once the Ultraviolet water purification system came on the line, the equipment produced the product on specification immediately after start up.
