100% ET TEST Stainless Steel Tube,Welding Tube Used for Boiler with grade 316/316L

 

ASTM A249/A249M Stainless Steel heat exchanger tube

 

This specification covers welded austenitic stainless steel tubing intended for high temperature usage such as boiler, superheater, heat exchanger, or condenser tubes.

 

       1.Application:

 

         Boilers, heat exchanger, heaters or condensers.

     

        2.Tube Grades:

       

        304,304L, 316, 316L, 321, 310, 310S, 309S

       

        3.Available Sizes:

         

        OD from 1/2’’ to 4’’

         

        Wall Thickness: 0.035’’ to 0.109’’ (0.9 mm to 2.77 mm)

 

All tubing is produced with the most advanced Hydrogen Bright Annealing units and weld bead cold working equipment. Only approved raw material suppliers are used that provide uniform wall thickness, Rockwell hardness, strength and elongation. The work cells are equipped with precise roll form tooling, regularly scheduled laser alignment and in-line eddy current testers with automatically programmed cut-out saws. This provides tubes that are produced to the tightest OD, ovality, straightness and length tolerances along with a superior weld condition.

Quality / Testing

SPEZILLA follows all requirements and testing procedures per SA/A249 requirements for austenitic grades and SA789 for duplex stainless types. Our work cells are equipped with in-line laser micrometers with constant digital readings that monitor ovality. In addition to the in-line eddy current test, tubes are also 100% air tested before final packaging. OD, length and straightness are held to more stringent tolerances than what is required by ASTM or ASME and are continually checked with ring and plug gages to dimensions provided by the customer / fabricator.
