Stainless Steel Spiral Wound Tube Bundle ASME SA213 TP304/316L High-Efficiency

Yuhong Group Co., Ltd. designs and manufactures thermal equipment including shell & tube heat exchangers (TEMA heat exchanger designs), pressure vessels, air coolers, and advanced spiral wound heat exchanger tube bundles. We also supply individual components: Fin Tube, Furnace Tube, Heat Exchanger Tube, Stainless Steel Seamless Tube, Nickel Alloy Tube, Copper alloy tube, heat exchanger tubesheet, and heat exchanger tube bundle. Our spiral wound bundles offer superior thermal efficiency and compact footprint for demanding cryogenic, petrochemical, and gas processing applications.

The stainless steel spiral wound tube bundle is a high-performance alternative to conventional straight-tube bundles. Instead of straight tubes, the bundle consists of multiple layers of spirally wound seamless tubes wrapped around a central core. Each tube layer is separated by spacers to create multiple flow passages. This design delivers extremely high heat transfer coefficients in a small volume, making it ideal for liquefied natural gas (LNG) plants, air separation units (ASU), and chemical reactors. Our bundles are fabricated from ASME SA213 TP304/304L or TP316/316L stainless steel seamless tubes, ensuring excellent corrosion resistance and strength at cryogenic temperatures.

• Up to 5* more heat transfer area in same shell diameter due to multiple tube layers
• High thermal effectiveness - true counter-current flow even in large temperature crosses
• Handles high pressure differentials - tube side can operate at very high pressure while shell side at low pressure
• Compact footprint - reduces plot space, piping, and insulation costs

• Precision winding: Computer-controlled winding machines ensure uniform tube pitch and layer spacing - critical for predictable thermal performance
• Tube-to-tubesheet joint: Tubes are expanded and seal-welded to the stainless steel tubesheet. Each joint is helium leak-tested for cryogenic service
• Layer separation: Spacers are welded to tube surfaces without damaging tube wall - a specialized process we have mastered
• Full material traceability: All tubes, spacers, and tubesheet come with ASME Section II Mill Test Certificates

• You need large heat transfer duty in a small shell (space-constrained retrofit)
• Your process requires very close temperature approach (e.g., gas liquefaction)
• Tube side fluid is high pressure (e.g., 100-200 bar natural gas)
• Shell side fluid is relatively clean (fouling can be managed by chemical cleaning)

• Cryogenic compatibility - 304/316L retains toughness down to -196°C (liquid nitrogen)
• Corrosion resistance - ideal for sour gas, amine solutions, and many chemical streams
• Leak-tight integrity - each tube individually tested before winding, and final bundle helium tested
• Long service life - stainless steel eliminates rust and general corrosion in most services

• LNG plants - main cryogenic heat exchangers (MCHE) - multiple spiral wound bundles in one shell
• Air separation units - nitrogen/oxygen liquefaction exchangers
• Ethylene plants - cold box exchangers
• Hydrogen liquefaction - low-temperature heat transfer
• Chemical reactors - spiral wound feed/effluent exchangers for high-pressure synthesis

Not ready for a full bundle? We also supply individual components:

• Stainless steel seamless tube (TP304/316L) - cut to length, with or without winding
• Spacer bars - precision-cut to your layer gap specification
• Heat exchanger tubesheet - forged stainless steel, drilled with spiral pattern
• Fin tube - for additional surface area on outer layers

To quote your stainless steel spiral wound tube bundle, send the following to jimmy@steelseamlesspipe.com:

• Required thermal duty (kW) and process fluids
• Tube side & shell side design pressure / temperature
• Shell internal diameter (or available space)
• Tube size (OD, wall thickness) and material preference (304 vs. 316L)
• Number of tube layers and winding pitch (if known)

Our engineers will perform thermal design, produce a winding drawing, and deliver a fixed price and schedule.
