Helical pipe coils

Expert production of helical and spiral coils for demanding applications

Precision coil geometry is essential for efficient heat transfer. Tulsa Tube Bending delivers certified ASME Section I and VIII helical and spiral coils built for chemical processing, power generation, thermal fluid systems, and food and beverage applications. From 1-inch OD to 8-inch IPS, we bend carbon steel, stainless steel, copper, nickel alloys, and exotic materials with exacting care.

A helical coil forms a continuous three-dimensional spiral with a fixed pitch and diameter. This geometry offers a compact footprint with strong fluid dynamics, reducing pressure drop and improving heat transfer. Helical coils are ideal for hot oil heaters, process heaters, and compact systems where thermal performance matters. Spiral coils, in contrast, are wound in a flat, circular plane. They expand outward to maximize surface area and are often used in heat recovery systems and viscous fluid processes where access for cleaning and efficient thermal exchange is essential. Both designs support precise flow, heating, or cooling requirements, depending on the application.

Tulsa Tube Bending’s coil capabilities go far beyond the basics. Our team creates complex, multi-pass coils and multi-helix configurations, all shaped to your design. We use precise bending processes backed by decades of innovation, along with certifications that meet the most demanding industry codes.

Frequently asked questions

Helical pipe coils involve shaping straight pipe or tubing into a spiral or helical form, commonly used in applications requiring efficient heat transfer or fluid flow within a compact space.

Helical coils maintain a constant diameter and pitch, forming a three-dimensional spiral, while spiral coils expand outward in a flat plane, increasing in diameter as they wind. Each design serves specific industrial applications based on space constraints and heat exchange requirements.

Materials commonly used include carbon steel, stainless steel, copper, nickel alloys, and other malleable metals. The choice depends on the application’s temperature, pressure, and chemical compatibility requirements.

Industries such as petrochemical, power generation, food processing, and chemical manufacturing use coiled pipes for heat exchangers, process heaters, and fluid systems.

Coiled pipes offer enhanced heat transfer efficiency, reduced pressure drop, and space-saving designs, making them ideal for compact systems requiring effective thermal management.

The process utilizes specialized machinery, such as roll benders, to shape the pipe into the desired coil configuration while maintaining structural integrity.

Fabrication often adheres to standards such as ASME Section I and Section VIII, ensuring the coils meet safety and quality requirements for pressure vessels and heat exchangers. Tulsa Tube Bending employs a comprehensive quality system, including inspection and testing processes, to ensure products meet customer specifications and industry standards.
