Yuhong Group Co., Ltd. specializes in the engineering and supply of thermal equipment components, with particular authority in shell-and-tube heat exchanger tubing solutions. Our facility operates under ASME, ABS, DNV-GL, BV, LR, and TUV certifications, supplying seamless tubing for critical heat transfer applications across the petroleum, petrochemical, and natural gas industries. We provide not merely tubes, but engineered solutions dimensioned to TEMA and ISO 16812 standards, ensuring optimal thermal efficiency and structural integrity under specified operating conditions.
ASTM A269 covers seamless and welded austenitic stainless steel tubing intended for general corrosion-resistant service. The 316L grade, with its molybdenum addition, offers enhanced resistance to pitting and crevice corrosion in chloride environments compared to 304/304L.

Heat Treatment: Mandatory solution annealing for seamless tubes. After final cold drawing, heat treatment shall be conducted to ensure uniform grain structure and eliminate residual stresses, critical for tube-to-tubesheet joint integrity.
Surface Finish: Available in bright annealed (BA), polished, or pickled condition to suit specific service environments.
Mandatory Testing Per ASTM A269/A1016:
Yuhong Group maintains extensive in-house processing capabilities supporting complete heat exchanger fabrication.

The ASTM A269 316L seamless tube is specified for shell-and-tube heat exchangers in:
Operating temperature range: Up to approximately 400°C (750°F) for non-pressure boundary service. For elevated temperature or creep-critical applications, ASTM A213 may be more suitable.
Not directly. ASTM A213 mandates seamless construction, tighter tolerances, and mandatory non-destructive testing for high-temperature and pressure boundary applications. ASTM A269 covers seamless or welded tubes for general corrosion-resistant service. For low-to-medium pressure heat exchangers operating below 400°C, A269 seamless tubes offer a cost-effective solution.
The primary distinction is carbon content: 316L has a maximum carbon content of 0.035%, versus 0.08% for 316. The lower carbon content in 316L reduces susceptibility to intergranular corrosion (sensitization) after welding, making it preferred for heat exchanger tube-to-tubesheet joints.
