Heat Exchanger Tubes

ASTM B862 Grade 2 Cold Rolled Titanium Heat Exchanger Seamless Tube ASTM B862 Grade 2 titanium tube is a commercially pure titanium tubular product designed for corrosion-resistant heat-transfer service, particularly in environments where seawater, chlorides, brine, wet chlorine, organic acids, or oxidizing media make stainless steel or copper-nickel unreliable. Grade 2 / UNS R50400 provides an optimal balance of corrosion resistance, formability, weldability, and moderate

Aluminum Finned Tubes G Type Finned For Industrial Heat Exchangers Aluminum G-Type Finned Tubes for Industrial Heat Exchangers Aluminum G-type finned tubes are mechanically embedded finned tubes designed for efficient air-side heat transfer in industrial heat exchangers. The aluminum fin strip is wound into a machined helical groove on the base tube and then mechanically locked, giving stronger fin retention and more stable thermal contact than simple wound fin constructions.

SA178 Grade A / Grade D Electric Resistance Welded Boiler Tubing SA178 Grade A and Grade D electric resistance welded boiler tubing is a minimum-wall carbon steel tube specified for boiler tubes, boiler flues, superheater flues, and safe ends. The ASTM/ASME specification officially covers only three grades—Grade A, Grade C, and Grade D—and the normal size range commonly supplied under the standard is 12.7–127 mm OD with 0.9–9.1 mm wall thickness. After welding, tubes are heat

G Type Finned Tubes — Embedded Fin Tube on Stainless Steel Pipe for Heat Exchangers Material G-type (embedded) finned tubes are stainless-steel base tubes with a helical groove machined on the outer wall. An aluminum, copper, carbon steel, or stainless steel fin strip is wound into the groove under tension, and the displaced base-metal is rolled back to mechanically lock the fin—forming a tight, gap-free metal-to-metal interface ideal for high vibration and cyclic thermal

G Type Fin Tube SA179 Stainless Steel Finned Aluminum Tubing For Heat Exchanger 【Material】 The G Type Fin Tube consists of a carbon steel base tube (SA179) and aluminum fins that are mechanically embedded into the outer surface of the tube in a G-shaped groove. This design ensures excellent thermal contact between the fin and the tube, enhancing heat transfer efficiency while maintaining mechanical stability. 【Specifications】 Base Tube Material: ASTM A179 Seamless Carbon

Finned Tube Stainless Steel Welded Pipe — G-Type Fin Tube for Industrial Radiators Material This product is a G-Type (embedded) finned tube composed of a stainless steel base tube with external fins securely embedded into helical grooves on the tube’s external surface. The base tube material is typically austenitic stainless steel (for example grades such as TP 304, TP 316, TP 321, etc) or other alloy steels suitable for welded fin-tube manufacture. The fins may be made of

Stainless Steel U Shape Pipe – Cold-Bent U-Shaped Steel Pipe for Heat Exchangers Material Overview Stainless Steel U Shape Pipes (U-bent tubes) are fabricated by cold bending seamless or welded stainless steel heat exchanger tubes into precise U or multi-U geometries, followed by stress-relief or solution annealing where required. They are designed for shell-and-tube heat exchangers, condensers, boilers, and feedwater heaters operating under high temperature and pressure, and

Overlapped L Type Fin Tube Carbon LL Type Finned Tube for Heat Exchanger Product Overview Overlapped L type fin tube, also called LL type finned tube or LL-foot fin tube, is a tension-wound finned tube where L-shaped fins are helically wrapped around a carbon steel base tube and each fin foot overlaps the previous one. This creates a double “L” foot that completely jackets the outer surface of the tube. For carbon LL type fin tubes, the base tube is typically seamless low- or
