ASTM A269 TP316L Stainless Steel Coil Tube Bright Annealed Tube Coil
YUHONG GROUP offers small diameter tubing in pre-cut lengths from stock or custom, stainless steel tubing can be made to order. Small diameter stainless steel tubes is used by companies across numerous industries including Aerospace, Automotive, Electronics, Oil and Gas, Fiber Optics, Renewable Energy, and Medical Device. Coiled tubing makes long length tube installations possible without the need for joining fittings. This reduces installation time and costs as well as eliminates potential leak points.
Stainless Steel Coil Tubes are finished in accordance with customer needs regarding dimensional and wall thickness specifications as well as heat treatment for more demanding applications. In general a Stainless Steel Coil Tube is manufactured according to current standards API, ASTM, and ASME. If required for special projects we can also supply large diameter Coil Tubes.

Advantages of ASTM A269 TP316L Stainless Steel Coil Tube
Compact Design: High surface area-to-volume ratio saves space.
Efficiency: Enhanced heat transfer due to turbulent flow in helical designs.
Versatility: Customizable to fit complex geometries and harsh environments.
Durability: Corrosion-resistant alloys (e.g., TP316L) ensure long service life.
Design Considerations
Thermal Performance:
Surface Area: Coil geometry (pitch, diameter) impacts heat transfer efficiency.
Flow Dynamics: Turbulent vs. laminar flow affects pressure drop and energy use.
Mechanical Factors:
Pressure Rating: Wall thickness and material strength determine operating limits.
Thermal Expansion: Compensate for expansion/contraction in high-temperature systems.
Material Compatibility:
Resistance to corrosion, erosion, or fouling from process fluids (e.g., seawater, acids).
Application
Heat Exchangers:
Shell-and-tube, plate-and-frame, or double-pipe designs for industrial processes.
Used in power plants, refineries, and chemical plants.
HVAC&R Systems:
Evaporators, condensers, and chillers in air conditioning and refrigeration.
Process Heating/Cooling:
Reactor coils in chemical/petrochemical industries.
Cryogenic coils for liquefied gas storage.
Renewable Energy:
Solar thermal collectors and geothermal heat pumps.
Medical/Pharmaceutical:
Sterilizers, autoclaves, and bioreactors requiring sterile, corrosion-resistant tubing.
