DIMENSION CHECK |
|
To ensure dimensional accuracy of OD, ID, Thickness, Length, Ovalityetc. |
|
|
SURFACE CHECK |
|
To ensure that finished tubes are free from scale, pit marks rupture I.D. & O.D scores, roll marks, dent etc. |
|
|
CHEMICAL TEST |
|
To test chemical constituents & quality parameters of raw materials & finished products. |
|
|
HARDNESS TEST |
|
It is carried out by Rockwell I Twin Hardness Testers.(HRC, BHN Scale) |
|
|
TENSILE TEST |
|
It is carried out by Electronic Digital, Universal Testing Machine with Graphical Presentation. |
|
|
FLARING TEST |
|
To Check the ductility of material, end of tube should be flared successfully without developing cracks |
|
|
FLATIENING TEST |
|
This test is conducted to check the strength by subjecting to extreme compression stress. If the test piece withstands the specified compression stress without cracking, it is determined to e acceptable. |
|
|
FLANGE TEST |
|
The photo shows a test piece subjected to Flange Test as per standard. |
|
|
BEND TEST |
|
Pipes are bended as per specification at 90 Deg. without developing cracks. |
|
|
HYDRO TEST |
|
(Up to 1500 bar) 100% Hydrostatic testing is carried by precision machine on all tubes. |
|
|
EDDYCURRENTTEST |
To detect subsurface inhomogeneities from inside & outside of tubes. |
|
|
ULTRASONICTEST |
|
For detection of subsurface flaws & imperfections. |
|
|
AIR UNDER WATER (PNEUMATIC) : |
This test is carried out on request.
It is carried out by immersing the tubes in water under compressed air to determine minor leakages.
In addition to above, several other tests are carried out at the request of customers, such as micro structural examinations, grain size determination etc. as per the specifications. |
