Ekaislot — High-Performance Reactor Internals & Process Efficiency Solutions
Engineering-first
Who We Are
Ekaislot is an engineering-driven manufacturer specializing in reactor internals and separation technologies. Originating from technology collaboration with France’s EUROSLOT, we support global customers with integrated capabilities—from early technical clarification and co-design to special material fabrication, FAT, and full final documentation.
What Makes Us Different
We are not a “build-to-print” workshop. We act as an overall solution provider focused on process efficiency and lifecycle performance—so your project can achieve measurable improvements, pass audits smoothly, and run reliably for years.
Manufacturing
Precision fabrication for special-alloy reactor internals, pressure vessels, thin film evaporators, and pilot skids.
Global Trade
Material sourcing, export-ready packaging, international documentation, and support for multi-region projects.
Critical internals
What We Do
Hastelloy, titanium, and high-temperature / high-pressure alloy welding and machining for severe service conditions.
Automatic plasma welding, 100% radiographic testing (RT) for critical welds, and full material traceability (MTRs).
Process simulation, engineering design, fabrication, factory acceptance testing, and on-site commissioning support.
Built on proven delivery
Milestones
Joint venture established in Shanghai through EUROSLOT technology collaboration
Established our Shanghai base to localize core internals know-how with in-house engineering. Built the foundation for end-to-end delivery, from technical clarification to fabrication and documentation.
ASME U Stamp certification; first international CCR reactor internals project delivered
Achieved ASME U Stamp capability and completed our first export CCR internals package. This validated code-aligned manufacturing, disciplined FAT execution, and international-ready documentation standards.
ISO 9001 / 14001 / 45001 certifications
Implemented ISO systems to standardize quality, environmental, and safety management across projects. Customers benefit from repeatable processes, smoother audits, and consistent traceability from MTRs to final dossiers.
China Pressure Vessel manufacturing qualification (D1 / D2)
Obtained China D1/D2 pressure vessel manufacturing qualification to support integrated equipment supply. Enabled more compliant, controllable fabrication workflows and improved lead-time stability.
Upgraded to GB D-Class Pressure Vessel manufacturing qualification
Upgraded to GB D-class qualification to meet higher duty requirements and stricter review standards. Improved acceptance efficiency and strengthened delivery confidence for complex projects.
Recognized as a National High-Tech Enterprise
Recognized for sustained R&D and engineering capability in reactor internals and process equipment. Accelerated collaboration with licensors, institutes, and universities on performance-focused solutions.
Recognized as a Specialized & Innovative (SRDI) enterprise
Awarded SRDI status, highlighting specialized, refined, and innovation-driven manufacturing. Reinforced our focus on severe-service materials, precision fabrication, and lifecycle performance improvements.
Strategic Partnership with Nantong Sanqiang & Establishment of Jiangsu Subsidiary
Shanghai Ekaislot strategically invested in Nantong Sanqiang Company. In September, Ekaislot (Jiangsu) Machinery Technology Co., Ltd. was officially established in Rugao, Nantong, marking a significant expansion of our manufacturing footprint.

About
Brand Story
EKAISLOT’s journey began in the heart of China’s petrochemical industry, where decades of hands-on plant experience—from PTA operations and overseas technical exchanges in the U.S. to leading critical startup projects such as the Xinjiang Urumqi facility—forged a deep understanding of high-performance process equipment.
This foundation led naturally to a role as the authorized agent for Europe’s leading reactor internals brands, bridging advanced international technology with China’s growing industrial demand. Recognizing the long-term dependency on imported core components, we founded EKAISLOT in Shanghai in 2012 to localize design and manufacturing, beginning with reactor and tower internals.
Building on this expertise, we have since expanded our capabilities from internals into integrated equipment solutions, including high-efficiency separators, triple-function units, and thin-film evaporators—each developed to enhance process performance, energy efficiency, and operational reliability.
Today, EKAISLOT serves a forward-looking portfolio of industries: from petrochemical and refining to new energy, environmental systems, nuclear power, and fine chemicals. We continue to engineer with precision, partner with purpose, and deliver solutions that help our clients—and industries—move forward.
