SS Coils for Refinery Plants
High-efficiency seamless stainless steel heating and cooling coils engineered for zero-leak thermal processing in edible oil and chemical refineries.
Mastering Heat.
Preventing Leaks.
Efficient thermal dynamics are the heart of any refinery. A single micro-leak in a heating coil can contaminate an entire batch of oil, costing thousands of dollars.
Optimal Thermal Dynamics
Our custom-bent SS Coils maximize surface area contact inside processing vessels. Whether circulating high-temperature thermic fluids or chilled water, they guarantee rapid, uniform heat exchange without creating burnt localized spots.
Heavy-Duty Seamless Fabrication
We utilize only premium-grade, heavy-wall seamless Stainless Steel (SS-304/SS-316L) pipes. Every coil is precisely bent using advanced CNC mandrels to prevent pipe thinning or wall collapse at the curves.
All joints undergo 100% Argon TIG welding and are hydro-tested at extreme pressures to ensure absolute structural integrity under thermal stress.

High-Velocity Heat Exchange
In refinery deodorizers and bleachers, achieving the right temperature quickly is critical. Our internal coils and exterior limpet coils are pitched precisely to maintain a high-velocity flow of the heating medium.
This prevents the stagnation of steam or thermic fluid, maximizing thermal transfer efficiency and drastically reducing batch processing times.

Zero-Defect Argon Welding
A single pinhole leak inside an oil deodorizer can cause catastrophic oxidation and product loss. We mitigate this risk by utilizing certified TIG (Argon) welding for every single coil joint.
All coils are subjected to Dye Penetrant Testing (DPT) and severe hydrostatic pressure testing (up to 30 Bar or higher based on specs) before they are cleared for installation inside a vessel.
Operational Capabilities
Built for Extreme Conditions
Every coil is pressurized far beyond working limits to guarantee safety.
Zero-leak argon welded joints, fully inspected and certified.
Engineered to safely sustain high-temperature thermic fluid circulation.
Technical Specifications
Engineered Features
Fabricated using advanced CNC pipe bending technology to match the exact curvature of your vessels without crimping or flattening the pipe walls.
All joints and header connections are TIG welded with inert Argon gas shielding to prevent internal oxidation and ensure a perfectly clean, slag-free joint.
Available as exterior half-pipe limpet coils for space-saving heating, or as full internal helical coils for rapid batch temperature manipulation.
Constructed from premium Stainless Steel 304 or 316L, ensuring supreme resistance to acidic oil compounds and long-term rust prevention.
Every single coil is subjected to severe Dye Penetrant Testing (DPT) and X-ray checks on weld seams to certify them 100% leak-proof before dispatch.
Headers and distribution manifolds are engineered to ensure equal pressure and flow velocity across all loops, preventing fluid stagnation.
Implementation Protocol
How We Work
Our engineering teams calculate and fabricate every coil to perfectly match the thermodynamic requirements of your refinery vessels.
Thermal Calculation
We evaluate the required heat load, fluid velocity, and specific vessel dimensions to calculate the exact pipe diameter, length, and pitch spacing needed.
Precision Fabrication
Utilizing heavy-duty CNC bending machines, seamless pipes are rolled to exact radii and argon-welded by certified technicians in our ISO facility.
Testing & Integration
Every coil assembly undergoes intense hydrostatic pressure tests. Once cleared, it is securely welded into the main vessel or dispatched for site installation.
Setting the Benchmark in Thermal Hardware
A failure in a heating coil doesn't just ruin a batch—it causes massive downtime. We engineer robust, fail-proof thermal coils that provide ultimate heat transfer and chemical resistance, protecting your operations and your profits.
Corrosion Proof
Fabricated with premium SS-316L/304 to withstand aggressive fatty acids, moisture, and reactive chemicals.
Thermal Efficiency
Optimized pitch and diameter designs ensure rapid heating/cooling cycles, saving massive energy costs.
Zero Leakage
Seamless pipe construction and 100% Argon TIG welded joints eliminate the risk of oil contamination.
Custom Scalability
Engineered specifically to the inner diameter and height constraints of your existing refinery vessels.
Case Studies & Endorsements
Industry Testimonials
"We were experiencing repeated pinhole leaks with our old mild steel coils inside the deodorizer, leading to massive product loss. After upgrading to these heavy-gauge SS-316L seamless coils, our thermal transfer is faster, and we haven't had a single pressure drop issue in over two years."

Frequently Asked Questions
For refinery applications, we strictly use high-grade Stainless Steel (SS-304, SS-316, or SS-316L) seamless pipes. This prevents rust and withstands aggressive fatty acids found in oils.
For critical high-pressure heating using thermic fluid or steam, we exclusively use seamless pipes. This eliminates the risk of a longitudinal weld seam splitting under thermal stress.
Internal helical coils sit inside the vessel in direct contact with the oil for very rapid heating. Limpet (half-pipe) coils are welded to the exterior of the vessel, saving inner space and making the vessel easier to clean.
Yes. If you provide the internal dimensions (ID) of your vessel and the required heat load, we can custom-bend and fabricate a replacement coil assembly to fit perfectly.
Every coil undergoes intense Hydrostatic testing where it is filled with water and pressurized far above its working limit (often 25+ Bar) to verify that zero pinhole leaks exist.
Our coils are engineered to safely handle high-pressure steam, high-temperature thermic fluids (up to 300°C), as well as chilled water or refrigerants for cooling cycles.
Yes. Beyond just fabricating the coils, our certified welders and technicians can travel to your site to install and safely weld the new coil assemblies into your existing vessels.
We use advanced CNC mandrel tube benders. The internal mandrel supports the pipe from the inside during the curve, ensuring the pipe remains perfectly cylindrical without any wall thinning or flattening.
We utilize highly precise TIG (Tungsten Inert Gas) welding with Argon gas shielding. This provides a deep, clean, and slag-free weld that is essential for high-pressure applications.
For custom coil assemblies, fabrication and testing usually take between 3 to 6 weeks, depending on the pipe diameter, total length required, and current raw material availability.
