Apache Stainless Equipment Corporation, a manufacturer of ASME pressure vessels, was contracted to provide four (4) large columns for a renewable energy company. Apache’s “Large Vessel” fabricators/ welders manufactured four stainless columns that measured up to 167’ in length, 11’ width, and 112,000 lbs. in dry weight.
Government and public opinion will drive growth in the industry, and Apache is poised to support large tank projects with the staffing, expertise, and facilities to manufacture ethanol and biofuel tanks.

There are several reasons why a vessel may need service, however, two main causes why a vessel may need service are either accident or performance related.
In the case of an accident, such as a tool falling into the tank and causing damage; surface scratches and dents can typically be repaired on-site, provided they do not go beyond minimum requirements, with mechanical polishing or hand/wand electropolishing.
Reduced agitator performance or failure is often due to worn parts, improper assembly or a bent or broken shaft. Agitator repairs may be addressed with the agitator manufacturer or the vessel manufacturer, depending on the situation, down-time, and severity of the failure.
When troubleshooting a drop in pressure in a tank or vessel, a typical cause is often related to seals. One sign of seal failure is product coming out of the seal. To help reduce the frequency of an unexpected seal leak occurring, it is recommended to use a good seal maintenance program to solve a lot of pressure / performance issues, such as:
• Seal replacement has been neglected
• Flat spots on seals are a sign for replacement
• Improper or incorrect seals for the outlet
• Nicks, scratches or mishandling of seals
A best practice is to avoid product waste and critical down-time is to inventory seals for all outlets and manage seals in a preventative maintenance program.
It is important to note that any weld repairs to the ASME pressures zones on tanks, require an R-Stamp. The R-Stamp is a certification required by the National Board of Boiler and Pressure Vessels for repair of an ASME tank or vessel.
Depending on the size of the vessel and type of repair, Apache’s service techs may be able to make repairs on site or in some cases, tanks are shipped back to the factory. Apache can provide services including:
• Field service and troubleshooting to all types of stainless and high alloy tanks
• ASME / National Board R-Stamp repair and modifications
• Surface finish repairs
• Non-code repairs and modifications including piping and heat transfer jackets
• Seal and agitation repairs and modifications
• Accessory repairs
• Head and tank shell repairs
• Leak detection
• Audit and service contract available

Apache Stainless is exhibiting at the FEW (Fuel Ethanol Workshop & Expo) on Jun 19 - 21st, 2017 at the Minneapolis Convention Center in Minnesota. This is the 33rd year that the show has been running, where everyone in the industry from scientists to vendors can hear about future trends, learn about new technology and network with experts in the industry. And this is the 18th year that Mike Peterson is exhibiting , Apache's expert in tank and vessel sales support for the industry. Visit Mike at Apache's booth, #1637.
Ethanol is a renewable fuel made from corn and other plant materials known as "biomass". More than 95% of US gasoline contains ethanol which oxygenates the fuel and reduces air pollution. Apache Stainless has proudly been supplying this environmentally driven and innovative industry since 1975. We fabricate Mix, Tanks, CO2 Scrubbers, Yeast Tanks, Distillation Columns, Atmospheric Tanks and ASME Vessels to the Biofuel and Ethanol industry.
