ASTM A269 TP304 Bright Hydraulic Tube Hardness / Flattening
Mechanical Testing
Stainless steel seamless bright annealed tube’s final surface is
polished and bright annealed. And the polished grade is includes
180 # , 320 # , 400 # , 600 # , 800 # . According to standard very
strictly , tubes which produced by us always have correct OD and WT
tolerance. And they are very suitable for chromatography industry.
Where can be used ?
1 . General service industries ( petroleum , food , chemical ,
paper , fertilizer , fabric , aviation and nuclear
2 . Fluid , gas and oil transport
3 . Pressure and heat transmission
4 . Construction and ornament
5 . Boiler heat exchangers
6 . Decorative usage ( road lamp facilities , bridge handrail ,
expressway railing , bus stop , airport and gymnasium ) boiler ,
auto parts , medical equipment , building materials , food industry

MTSCO has been dedicated to producing bright annealed tubes since
2014 , owning complete producing technology and abundant managing
experience . And the raw material such as mother tube , round bar
we use is from Chinese biggest and well-known steel mill : Walsin ,
Yongxing etc . Also we have advanced NDT equipments for the tests
such as Eddy Current test , Ultrasonic test , Hydraulic test and so
on . Welcome you contact us in free !
| Corrosion Test | If clients need will be conducted |
| Chemical Analysis | Will be tested as per required quality standards |
| Destructive / Mechanical Testing | Tensile / Hardness / Flattening |
| Eddy Current Testing | Using digital flaw-mark testing System to do test and mark in
surface homogeneities |
| Hydrostatic Testing | 100% Hydrostatic Testing carried out according to ASTM-A 450 norms
for checking tube leakage, and biggest pressure we can support
20Mpa/7s . |
| Air Under Pressure Test | To check any evidence of air leakage |
| Visual Inspection | After passivation, every single length of tubes is subjected to
thorough visual inspection by trained staff for detecting surface
flaws & other imperfections |
