Roben, Mfg, Inc. is a leading provider of custom corrosive material storage tank fabrication services, specializing in the design, engineering, and manufacturing of tailor-made storage solutions for highly aggressive and corrosive substances. With our expertise, state-of-the-art facilities, and commitment to safety and longevity, we deliver custom corrosive material storage tanks that meet the unique requirements of our clients and withstand the harshest chemical environments.
How do you determine the most suitable material for a corrosive material storage tank?
We determine the most suitable material through a comprehensive analysis that considers
- Chemical composition and concentration of the stored corrosive material
- Operating temperature and pressure
- pH levels and potential for pH fluctuations
- Presence of impurities or contaminants
- Mechanical stress requirements
- Expected service life and maintenance considerations
- Cost-effectiveness and availability of materials
Our materials engineers use corrosion databases, predictive models, and laboratory testing when necessary to make the optimal material selection.
Can you provide tanks for extremely aggressive chemicals like hydrofluoric acid or concentrated sulfuric acid?
Yes, we have extensive experience in designing and fabricating tanks for extremely aggressive chemicals. For substances like hydrofluoric acid or concentrated sulfuric acid, we might consider
- Specialized alloys (e.g., Monel for hydrofluoric acid)
- Fluoropolymer linings (e.g., PTFE, PFA)
- Dual laminate constructions
- Carbon brick-lined steel tanks
The specific solution depends on the concentration, temperature, and other process conditions. We also incorporate advanced safety features and monitoring systems for these highly hazardous materials.
How do you ensure the long-term integrity of welds in corrosive material tanks?
Ensuring weld integrity is crucial for corrosive material tanks. Our approach includes
- Using specialized welding procedures and qualified welders experienced in corrosion-resistant materials
- Employing automated welding techniques where applicable to ensure consistency
- Utilizing compatible filler materials that match or exceed the corrosion resistance of the base metal
- Performing post-weld heat treatments when required to restore corrosion resistance
- Conducting thorough non-destructive testing (NDT) on welds, including radiography, ultrasonic testing, and dye penetrant inspection
- Applying additional corrosion protection to weld areas, such as overlay welding or localized coating application
What types of linings or coatings do you offer for corrosive material tanks?
We offer a wide range of linings and coatings for corrosive material tanks, including
- Fluoropolymer linings (PTFE, PFA, ETFE)
- Rubber linings (natural rubber, chlorobutyl, bromobutyl)
- Glass flake-reinforced epoxy coatings
- Vinyl ester linings
- Phenolic linings
- Ceramic tile linings
- Metallic spray coatings
- Fusion-bonded epoxy coatings
The choice of lining or coating depends on the specific corrosive medium, temperature, and other operational factors.
What are the typical lead times for custom corrosive material storage tank fabrication?
Lead times for custom corrosive material storage tanks can vary depending on the size, complexity, and materials used. Typical lead times range from 14 to 40 weeks, broken down as follows
- Corrosion analysis and material selection: 2-4 weeks
- Design and engineering: 3-6 weeks
- Material procurement: 4-12 weeks
- Fabrication and lining/coating application: 6-20 weeks
- Testing and quality control: 1-2 weeks
We work closely with our clients to establish realistic timelines and keep them informed of progress throughout the fabrication process. For urgent needs, we may be able to offer expedited fabrication options.
