ASME SA 249 TP304 Welded Stainless Steel Tubes Conditions

We have complete sets of production lines, including auto welding machines and bright annealed device, production capacity can meet kinds of requirement and additional value service, like U bend tube ,bright annealing welded tube , cold drawn precision tube.

U Bend Welded Tube

In heat exchanger system, it often requires U bend type stainless steel tubes, U bending tube has benefits to save cost. leg length max 12 meters, radius max 1.5 meters, bending part should be heat treated to relieve stress, thereafter pickling to ensure tube surface clean.

Bright Annealing Tube

Bright annealing and annealed pickling processes can eliminate the scaling to make inside and outside surface clean, inert gas hydrogen air in closed furnace, then heat treatment improve tube roughness, it made tube more brighter, when it is installed in heater and cooler system, that will be easy as well as to clean.

Depending on the application, A249 316 or 316L grade can endure higher temperatures than other grades of stainless steel. It is much better than 304 and 304L grades.

If you would like to extend the life of stainless-steel tubes in harsh environments, 316/316L welded tubing is an excellent option for heat exchangers, superheaters, and boilers due to its high corrosion resistance and ability to resist internal and external corrosion.
