STKM 13A Carbon Steel Seamless Precision Tube (Thick-Walled) for Mechanical Engineering Material STKM 13A is a JIS-grade carbon steel tube designed for machine-structural and general mechanical parts. As a seamless precision tube, it is commonly produced by hot-finished seamless tubing followed by cold working (e.g., cold drawing) to achieve improved dimensional accuracy, surface finish, and consistency—especially important for thick-walled load-bearing components and

ASTM A513 4130 Chromoly Cold Drawn Alloy Steel Precision (DOM) Tube / Pipe for Mechanical Engineering Material This product is ASTM A513/A513M Grade 4130 chromium–molybdenum (Chromoly) mechanical tubing manufactured by the ERW → Drawn-Over-Mandrel (DOM) → cold drawing route. ASTM A513 Type 5 DOM tubing is produced from electric-resistance-welded tube that is subsequently cold drawn over a mandrel to achieve high dimensional accuracy, improved concentricity, and a smooth bore

Crimped Fin Tube (Helically Tension Wound, Cold-Formed Finned Tube) for Air Coolers Material A Crimped Fin Tube (also called a Spiral Tension Wound / Cold-Formed Finned Tube ) is a heat-transfer tube where a metal fin strip is helically wound under controlled tension onto a base tube . The fin strip is pre-formed to widen the contact “foot,” then mechanically locked to the tube surface (with end fixing such as tack/tag welding or spot welding depending on design). Common

Low Fin Tubes Stainless Steel Integral Low Finned Tube for Industrial Heat Exchangers Material This product is an integral low finned tube manufactured from high-quality stainless steel . The fins are formed directly from the parent tube material through a cold-forming process, ensuring metallurgical continuity between the tube and fins. This construction provides excellent corrosion resistance, high structural integrity, and long-term reliability in demanding industrial heat

Extruded Fin Tube Steel Aluminum Bimetallic Composite Finned Tube For Oil And Natural Gas Material This product is a bimetallic extruded fin tube composed of a carbon steel or alloy steel core tube combined with an aluminum outer fin layer . The aluminum fins are formed by an extrusion process that permanently bonds the aluminum sleeve to the steel tube, ensuring excellent thermal contact and long-term stability. The steel tube provides pressure resistance and mechanical

Omega Tube SAE 1010 Precision Cold Drawn Special Shaped Seamless Tube For Boilers Material This product is a precision cold-drawn seamless steel tube manufactured in an Ω (omega) / special-shaped profile for boiler and heat-transfer service.It is commonly produced from SAE 1010 low-carbon steel , a grade known for excellent cold-formability, stable weldability, and consistent performance after cold working and stress relief/annealing , making it suitable for precision-profile
