Heat Exchanger Tubes

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

ASME SA213 Grade T12 Internal Thread Tube — Seamless Low-Alloy Tube for Heat Exchangers Material Overview ASME SA213 Grade T12 (UNS K11562) is a seamless chromium–molybdenum (Cr-Mo) low-alloy steel tube widely specified for boiler, superheater, and heat-exchanger service where elevated-temperature strength and pressure integrity are required. The ASME SA-213 specification is the Code adoption of ASTM A213/A213M for these seamless alloy-steel tubing applications. Specification

ASTM A213 Alloy Steel Seamless Pipe (Tube) — Large Diameter, Thick-Wall for Boiler Service Material ASTM A213/A213M covers seamless ferritic and austenitic alloy-steel tubes intended for boilers, superheaters, and heat exchangers . Tubes are supplied as hot-finished or cold-finished , and can be specified with the heat-treatment condition required for high-temperature pressure parts. (Reference: ASTM A213/A213M) Specifications Manufacturing : Seamless; hot-finished or cold

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
