ASTM A249 TP304 welded tubes for heat exchangers introduction
ASTM A249 TP304 heat exchanger welded pipe adopts classic 18Cr-8Ni austenitic stainless steel, which is specially designed for conventional corrosion and medium temperature heat exchange conditions of heat exchangers, condensers, coolers and other equipment.
ASTM A249 TP304 heat exchanger pipe supplied by GNEE is processed by cold drawing/cold rolling, pickling and polishing, with a surface roughness of Ra≤1.6μm, which reduces fluid resistance and scaling risks, improves heat exchange efficiency, maintains good toughness in the temperature range of -196℃~600℃, adapts to alternating hot and cold conditions, and reduces the risk of thermal fatigue cracking.

What is the difference between ASTM A249 TP304 welded pipe and 316L welded pipe?
Compared with 316L containing molybdenum or 347 stainless steel containing niobium, TP304 is 20%-30% cheaper. When the chloride ion content is ≤200ppm, it is an economical choice for equipment such as petrochemical condensers, air conditioning chillers, and food sterilization heat exchangers.

Full size coverage: outer diameter 10-508mm, wall thickness 0.8-12mm, supports thin-walled tubes (such as 0.8mm ultra-thin tubes for plate heat exchangers) and large-diameter tubes (such as 508mm shell-side main tubes), meeting the design requirements of different heat exchange areas and pressure levels (up to 30MPa).
Customized pretreatment: Bevel (V-type / U-type), cut to size (error ±5mm), and even pre-bend according to drawings, directly matching the hole position of the heat exchanger tube sheet to improve installation efficiency.
