Rathna Techno Solutions
Building Engineering Solutions with Experience, Precision and Commitment.
RTS is a trusted and rapidly growing engineering and industrial solutions company headquartered in Tiruchirappalli (Trichy), Tamil Nadu, with a branch office in Chennai. With more than 15 years of experience in static equipment design and analysis, we have developed strong technical capabilities and practical industry knowledge to support complex engineering and industrial requirements.
An Integrated Industrial Solutions Provider
Our journey began with a focused vision in Design & Engineering Services — particularly static equipment and mechanical engineering. Today, Rathna Techno Solutions has grown into an integrated industrial solutions provider offering capabilities across four core domains. This combination allows us to support clients at different stages of their projects while maintaining a strong connection between engineering, materials, fabrication, and site execution.

Key Capabilities
- Pressure Vessel Design
- Heat Exchanger Engineering
- Piping Stress Analysis (CAESAR II)
- Structural Design (STAAD.Pro)
- 3D Modelling (SOLIDWORKS, Plant 3D)
- Engineering Documentation
From Specialist Design to Integrated Industrial Partner
Rathna Techno Solutions was established with a commitment to provide dependable engineering services to industries where technical accuracy, quality, safety, and execution reliability are critical.
Foundation & Specialisation
Established with a focused vision in static equipment design and analysis. Built core competency in pressure vessel engineering, equipment calculations, and design codes including ASME, TEMA, and API.
Multi-Disciplinary Expansion
Expanded beyond equipment design into structural engineering (STAAD.Pro), piping stress analysis (CAESAR II), plant layout, 3D modelling, and comprehensive engineering documentation.
Integrated Execution Capability
Moved into strategic sourcing, mechanical erection, equipment fabrication, structural fabrication, piping, insulation, electrical contracting, and site manpower support.
Comprehensive Industrial Partner
Today, RTS offers full lifecycle engineering-to-execution delivery — from concept and detailed engineering through procurement, fabrication, site installation, and documentation handover.
Our Core Engineering Philosophy
At RTS, we believe that successful engineering is not simply about producing drawings or calculations. Good engineering should ultimately contribute to safe operation, efficient fabrication, ease of installation, maintainability, and reliable project execution.
We therefore approach every assignment by understanding the complete requirement rather than looking at individual engineering activities in isolation. This practical engineering philosophy allows us to create solutions that can move efficiently from design to fabrication and from fabrication to site execution.

Multi-Stakeholder Collaboration
This combination of engineering knowledge and practical understanding enables us to work effectively with clients, consultants, EPC contractors, manufacturers, fabricators, and site execution teams — ensuring smooth communication and coordinated delivery across all project phases.
From Engineering to Execution
One of our key strengths is our ability to understand the connection between engineering and field execution. A design may appear technically correct on paper, but successful project delivery also depends on whether the design can be fabricated efficiently, transported safely, installed correctly, inspected properly, and maintained effectively.
Detailed design, calculations, drawings, and specifications.
Certified material sourcing and vendor inspection.
Precision manufacturing with certified welding and QC.
NDT, PWHT, hydro-test, and third-party inspection.
Site installation, rigging, alignment, and commissioning support.
Databooks, as-builts, MTCs, and handover packages.
Constructability by Design
Our exposure to fabrication and site activities gives our engineering team valuable practical insight. This helps us consider constructability and execution aspects during the engineering stage itself — reducing communication gaps between different project activities.
Integrated Project Delivery
Our integrated approach helps clients achieve better coordination between engineering, procurement, fabrication, inspection, erection, and documentation — reducing costly site rework and schedule overruns.
Engineering Standards & Design Codes
Our engineering activities are carried out with reference to applicable international and national codes, standards, client specifications, and project requirements. The design code is selected based on equipment type, operating conditions, project specifications, and applicable statutory requirements.
The governing code for pressure vessel design, fabrication, and inspection across all RTS pressure-containing equipment.
Applied for shell and tube heat exchanger design — geometry, baffle design, tube arrangements, and mechanical standards.
Our primary reference for atmospheric storage tank fabrication and erection for the oil and petrochemical industry.
Applied for larger diameter and low-pressure storage systems, including LNG and chemical storage.
European standard applied when client or project specifications require European-compliant pressure equipment design.
Governs structural steel design for industrial structures — pipe racks, equipment supports, platforms, and buildings.
British standard for pressure vessel design applied for UK and Commonwealth client specifications.
German pressure vessel code applied for European petrochemical and process industry client requirements.
General engineering best practices applied alongside formal codes to ensure practical, workable, and maintainable solutions.
Quality is Part of Our Process
Rathna Techno Solutions is an ISO 9001:2015 certified company, demonstrating our commitment to structured quality management and continual improvement.
For us, quality is not limited to final inspection. It is a process that begins with understanding the requirement and continues through engineering, documentation, procurement, fabrication, inspection, and execution.
We continuously work toward improving our processes, strengthening technical capabilities, and maintaining consistency in project delivery.
Understanding client spec, project conditions, and compliance needs.
Code-compliant design and calculation review with quality checkpoints.
Material traceability, MTC verification, and approved vendor control.
WPS/PQR compliance, welder qualification, dimensional inspection.
RT, UT, PT, MT, hydro test, and PWHT per design code.
Databooks, as-builts, test certificates, and final documentation.
