The main difference between pickle passivation and electropolishing is the appearance and RA (roughness average) of the stainless material. In the photo, an electropolished sample is shown above a pickle passivated sample. The pickle passivated sample has a white appearance, while the electropolished sample has a mirror-like, shiny finish.
Pickle Passivation is the immersion of metal in a pickling bath such as nitric-hydroflouric acid. The process removes metal such as impurities and heat marks from welds.
Electropolishing is an electro-chemical process that removes surface material from stainless steel. The process typically starts with an immersion of the component into a controlled bath of electrolyte that is charged with a DC power supply. Apache’s RA tests show improvements up to 50% smoother, depending on the material.

This side agitator was engineered to mix food products with a high percentage of solids and viscosity in the processing of soups, sauces, marinades and gravies. The 2500 gallon tank acts as a large stock pot as part of the manufacturing process.
On the left photo, the tank (shown horizontal during manufacturing) was equipped with a half pipe jacket, which was pumped with heated fluid as required by the application. On the right, the tank head shows fittings and man way entry.

Apache fabricates tanks from one gallon to more than 165,000 gallon capacity that are custom fabricated for processors and manufacturers all over North America.
In the photo, the large distillation tank has been loaded on the trailer is embarking to Canada. It is 9 ft. in diameter, 137 ft. long and weighs in at 160,000 lbs. with a 71,000 gallon capacity. In the upper right is a small one gallon, pickle passivated, portable research tank for a chemical processor.
Our fabrication experience is also diverse. We manufacture ASME Vessels, API-650 Vessels, Custom Mix Tanks, Storage Tanks, Evaporators, Jacketed Vessels, Columns, Heat Exchangers and Vats and Totes.
Apache’s tanks and vessels are found in the beverage, biotechnology, commercial, health and beauty, pulp and paper, biofuel, chemical, food-processing, petroleum and water treatment industries.
Apache Stainless Equipment Corporation, a manufacturer of ASME pressure vessels, was contracted to provide two large falling film evaporators for a Canadian oil processing operation. Apache’s “Large Vessel” fabricators/ welders manufactured the two evaporators, made from 2205 and 2304 duplex materials that were each 13 ft. in diameter and 127 long. Each evaporator has an empty weight of approximately 330,000 lbs. The total operating weight of each evaporator will be approximately 880,000 lbs.
Both evaporators were needed for the Canadian Oil Sands development to extract oil out of the ground. Oils sands, or tar sands are loose sand and sandstone that contain sand, clay and water, which is saturated with a viscous form of petroleum. Oil produced from the Canadian oil sands is referred to as crude oil.
Apache provided the evaporators used to separate the water from the oil. In the process, infused water is pumped out of the ground, cleaned and pumped back into the ground as steam. The steam breaks up and “melts” the oil off the sand trapped in the ground. The oil mixture is then pumped through the evaporators where Apache installed over 3,000 2” diameter tubes into each evaporator. Inside the tubes, the oil and water fluid is subjected to heated steam, which causes the water to turn to steam and the oil separates and falls down the tubes, hence the name falling film evaporator. The separated oil then collects in a pipe where the oil is extracted. The steam is used to go back into the ground as it is now clean to comply with environmental concerns. The process is a continuous loop.
The two large evaporators were delivered utilizing five transports. The evaporators were split in half for transportation purposes, as the heaviest portion containing the tubes weighed over ¼ million pounds for each evaporator. Apache is one of the few vessel manufacturers that can handle this size of evaporator. We have close to 350,000 sq. ft. manufacturing facilities and an extensive, cross-trained staff of experienced fabricators that are flexible to work on various types of vessels, applications and materials.
Located in Beaver Dam, Wisconsin, Apache Stainless Equipment Corporation serves the fuel industry with many types of specialized tanks, including: distillation columns, evaporators, ASME vessels, API-650 vessels, clad vessels, custom mix tanks and storage tanks.
Madison Area Technical College engineering students presented their class project, a bio-diesel blending system, at the University of Wisconsin-Madison May 8th, 2013. Apache Stainless Equipment Corporation donated the tank used in the project and the biodiesel system will also be shown at collegiate fairs and educational outreach events.
The Madison College engineering students were tasked with developing a system that was capable of blending biodiesel with petro-diesel and fuel additives for improved performance in extreme seasonal temperatures. The students also had to design around safety, transportability, power and budget constraints. Apache was one of several equipment manufacturers to donate components to the project.
“Apache is committed to build strong community ties where we live, work and go to school,” says Ed Paradowski, Apache President, “being part of this project not only helps Madison College engineering students, it also helps with the overall promotion of education in the field of fabrication and manufacturing.”
As a group, students engineered the blending system from start to finish. Apache supplied a 60 gallon, pickle passivated stainless tank with a vent fitting according to their design and specifications. The welding, fabrication, plumbing and electrical was all accomplished by the introductory engineering students at Madison College.
Apache serves the biofuel industry with many types of specialized tanks, including: distillation columns, evaporators, ASME vessels, API-650 Vessels, clad vessels, custom mix tanks and storage tanks. The Apache facility in Beaver Dam, Wisconsin is fully equipped with machines and processes for shearing, forming, welding, rolling and in-house head making. The company also provides finishing capabilities, including automated mechanical polishing, electro-polishing and passivation. Another facility in Plover, Wisconsin produces carbon steel tanks and equipment.
Sanimax, a leading rendering and renewing process company, partnered with Apache Stainless Equipment Corp. to provide stainless steel tanks to support growing production of B100 Biodiesel fuel. The Sanimax facility in DeForest, Wisconsin is dedicated to the processing of 100% renewable Biodiesel fuel. Apache supported their need for increased capacity by supplying one atmospheric stainless tank and three pressure vessels within the past month.
According to IFP Energies, a public sector research and education center for energy, transport and the environment, Americans are taking an interest in alternative fuels. The center’s 2012 report states that USA has been the world’s leading producer and consumer of biofuels since 2007. Sanimax responds to that growth by increasing production capacity.
The most recent custom stainless steel tank supplied by Apache was used for fuel storage. The tank was constructed from stainless steel with exterior insulation and aluminum cladding. The tank increased storage capacity for Sanimax by 30,000 gallons. The 132” diameter, 45 ft. high and 19,000 lb. atmospheric tank was API 650 rated. Apache provided in-house insulation and aluminum cladding of the tank and was shipped via Apache truck.
Apache appreciates the partnership with Sanimax and their cooperation in telling this story!
