Custom Equipment Fabrication for Industrial Ammonia Systems
At R.M. Technologies of America, we take pride in our ability to transform complex engineering concepts into high-quality, physical assets. Our fabrication process is rooted in a deep understanding of the unique metallurgical and structural requirements necessary for safe ammonia handling. By maintaining a dedicated fabrication facility, we ensure that every skid, tank, and component meets our rigorous internal safety standards before it ever reaches your site.
I. Our Fabrication Specializations
We focus on "built-to-order" solutions that bridge the gap between standard off-the-shelf parts and the specific needs of your industrial process.
1. Modular Ammonia Skids
Our hallmark is the delivery of fully integrated, "plug-and-play" modular skids. These units centralize pumps, valves, instrumentation, and controls into a single, structurally reinforced frame.
- Pump Skids: Featuring sealless magnetic drive technology to eliminate leak paths.
- Vaporizer Skids: Precision-engineered heat exchange systems for anhydrous ammonia conversion.
- Dilution & Mixing Skids: Automated systems for the production of aqua ammonia or ammonium carbonate.
2. ASME Pressure Vessels & Storage Tanks
We fabricate and assemble ammonia storage solutions that adhere strictly to ASME Section VIII, Division 1 standards.
- Materials: Specialized use of 316L Stainless Steel for corrosive carbonate services and high-strength carbon steel for anhydrous storage.
- Testing: Every vessel undergoes rigorous non-destructive testing (NDT), including X-ray weld inspection and hydrostatic pressure testing, to ensure structural integrity under high-pressure conditions.
3. Specialized Piping & Manifolds
Ammonia requires specific piping geometries to prevent "trapped liquid" scenarios and thermal expansion issues.
- Welding Excellence: Our welders are certified to ASME Section IX standards, ensuring leak-free performance in high-vibration and high-pressure environments.
- Valve Manifolds: Custom-fabricated manifolds for truck unloading, railcar transfer, and process distribution.
II. The Fabrication Process: From Drawing to Delivery
Our vertically integrated approach ensures that nothing is lost in translation between the engineer and the fabricator.
- Material Procurement & Verification: We source only certified, traceable metals. In ammonia service, avoiding materials like copper, brass, or zinc is non-negotiable, as they react violently with the chemical.
- Precision Cutting & Fit-Up: Utilizing advanced CNC plasma and water-jet cutting to ensure components fit with surgical precision, reducing internal stresses during the welding process.
- Certified Welding & Assembly: Our technicians follow strict Weld Procedure Specifications (WPS) designed specifically for ammonia-resistant metallurgy.
- Factory Acceptance Testing (FAT): Before shipping, every system undergoes a comprehensive FAT. This includes:
- Pneumatic & Hydrostatic Testing: Verifying the pressure rating of all seals and welds.
- Electrical & Control Testing: Point-to-point wiring checks and PLC logic verification.
- Instrumentation Calibration: Ensuring all sensors and detectors are pre-calibrated to your specific setpoints.
III. Why Choose R.M. Technologies of America for Fabrication?
- Single-Source Accountability: We design, we build, and we support. There is no finger-pointing between separate engineering firms and fabricators.
- Reduced On-Site Labor: By delivering a pre-assembled, factory-tested module, we significantly reduce the time and risk associated with on-site construction.
- Durability for Harsh Environments: Our equipment is finished with industrial-grade, corrosion-resistant coatings or fabricated from high-grade stainless steel to survive decades in demanding chemical environments.
