High-Efficiency Heat Exchanger & Finned Tube Solutions

Precision engineering for refineries and hydro-treating units. With more than 12 years of specialized supply experience in the Iraqi oil and gas sector, we are a trusted provider of tubing solutions engineered to withstand the extreme thermal, pressure, and chemical conditions found in hydro-treating units, condensers, and industrial heat exchangers.

Stainless Steel Finned Tubes (ASTM A213 TP321)

Designed to enhance heat transfer efficiency in high-temperature applications.

• Material: ASTM A213 TP321 stabilized stainless steel, offering excellent corrosion resistance
• Dimensions: 25.4 mm O.D. x 4,877 mm length
• Fin Type: High-efficiency N-type fins, 16 fins per inch
• Finishing: 4-inch un-finned sections at both ends to ensure proper sealing and ease of assembly

Seamless Cold-Drawn Exchanger Tubes (ASTM A179 / ASME SA179)

Our ASTM A179 tubes are widely used in tubular heat exchangers and condensers. Manufactured through a seamless cold-drawn process, they deliver smooth internal surfaces, high thermal conductivity, and precise dimensional accuracy.

• Dimensions: 19.05 mm O.D. x 2.11 mm wall thickness x 12,000 mm length
• Process: 100% seamless, cold-drawn construction

Key Specifications

• Tensile Strength (min): 325 MPa
• Yield Strength (min): 180 MPa
• Max Hardness: 72 HRB

All A179 tubes undergo final heat treatment at 1200°F (650°C) or higher to relieve stress, stabilize mechanical properties, and ensure a clean, scale-free surface critical for efficient heat transfer.

Quality Assurance & Logistics

Every batch is subjected to comprehensive mechanical and hydrostatic testing and verified by independent third-party inspection agencies. For logistics, tubes are packed in heavy-duty, moisture-resistant export packaging with rust-preventive coatings and reinforced crates, ensuring reliability for refinery operations and critical energy infrastructure.
