TIG welding stainless steel heat exchanger tube

Welded stainless steel tube is applied for heat exchanger, boiler, condenser, super heater, we use automatic Tungsten Inert Gas (TIG) welding method, which has many advantages to produce tubes, it can protect stainless steel surface from oxidation, and no chemical reaction.

We produce TIG welding tube for heat exchanger manufacturers and designers, ASTM A249 is a custom standard for stainless steel heat exchanger tubes, we comply to this specification, standard testing and optional testing for inspecting quality.
