ASTM A179 Seamless Steel Tube For High Pressure Service for Boiler

 

Size: Outer Diameter: 6-1000 mm,Wall Thickness: 1- 80 mm,Length :1-12m or as your request

 

Application:Manufacture of Feedwater Heater

 

Material:10#.20#.16Mn.A106(B,C).ST35-ST52

 

 

Manufacture :Tubes shall be made by the seamlessprocess and shall be cold drawn.

 

Heat Treatment:

1)Cold-drawn tubes shall be heat treated after the finalcold-draw pass at a temperature of 1 200F [640C] or higher toensure ductility satis factory for rolling into tube sheets and tomeet mechanical properties as specified.

 

2)If stress -relief anneal of the U-bends is specified, theanneal shall consist of heating the bent portion within a rangeof 1100 to 1200F [585 to 640C].

 

 

Mechanical Tests Required:

1)Flattening Test One flattening test shall be made onspecimens from each end of two tubes selected from each lot(see Note l) or fraction thereof.

 

2)Flaring Test One flaring test shall be made on speci-mens from each end of two tubes selected from each lot (seeNote l) or fraction thereof. These tubes shall be selected apartfrom those used for the flattening test.

 

3)Hardness I Test Brinell or Rockwell hardness testsshall be made on specimens from two tubes from each lot. Theterm lot applies to all tubes prior to cutting, of the samenominal diameter and wall thickness which are produced fromthe same heat of steel. When final heat treatment is in abatch-type furnace, a lot shall include only those tubes of thesame size and the same heat which are heat treated in the samefurnace charge. When the final heat treatment is in a continuousfurnace, a lot shall include all tubes of the same size and heat,heat treated in the same furnace at the same temperature, timeat heat, and furnace speed.

 

4)Hydrostatic Test .Each tube shall be subjected to thehydrostatic pressure test, or instead of this test, a nondestruc-tive test may be used when specified by the purchaser.
