ASTM A688 Annealed and Pickled Welded Stainless Steel Tube For Feedwater Heater
Seamless Stainless Steel tubes For Boiler and Heat Exchanger, are made according to the Chinese National Standard GB13296-91.
GB13296-91 is a standard applicable for Seamless Stainless Steel pipes which is used for boiler and heat exchanger.
GB13296-1991 Seamless Stainless Steel Tubes for Boiler, Heat Exchangers
0Cr18Ni9 1Cr18Ni9Ti 0Cr18Ni12Mo2Ti
Technical tandard: GB13296-91
Tolerance for seamless stainless boiler tube:
|Cold Drawn(Cold Rolled)||OD||8~30||±0.20mm|
The length or general steel tube:
Hot Rolling(Extrusion) tube: 3~12 m
Cold Drawn(Cold Rolled) tube: 3~8 m
The length for water pipe & boiler steel pipe:
Hot Rolling(Extrusion) tube: 4~12 m
Cold Drawn(Cold Rolled) tube: 4~8 m
Both ends of the pipe should be cut at right angles, and remove burrs
Heat treatment of longitudinal mechanical properties of steel pipe shall according to the standard.
Tensile strength MPa
Yield Strength MPa
For the tubes which W.T. ≥2 mm, Rockwell hardness tests should be taken.
Tests of the seamless boiler tubes:
The tubes should take the bending test when OD ≤22mm. The bending angle is 90 degrees, and the bending radius is 6 times the outer diameter of the steel tube.
2. Hydraulic test;
Eddy current testing, ultrasonic testing can be used instead of hydraulic tests. When eddy current testing, GB/T 7735-1995 Gr. A should be followed; when ultrasonic testing, GB/T 5777-1996 Gr. C8 should be followed.
3. Flattening test
4. Flanging test
5. Expand test
