How Quality Testing Affects The Final Products Made ( Stainless Steel Tubes And Pipes)

Good quality defines all. And we make sure that we provide the best final product to our customers.

Good quality defines all. And we make sure that we provide the best final product to our customers. The products that we deal with mainly are Stainless Steel welded Pipes, Stainless Steel Welded Tubes, Stainless Steel Seamless Pipes, Stainless Steel Tubes, Stainless Round tubes.


The types of test that our product goes through are as follows:

1. Flaring Test:

The flaring test serves to establish the forming behaviors of tubes and pipes which are expanded to a specific degree with respect to O.D. This test is carried put in confirmation to the international standards.


2. Flattening Test:

A sample of tube or pipe in 4" length shall be flattened cold between parallel plates in two steps. The weld shall be placed at 90° from the direction of the applied force. The first step is a test for ductility, no cracks or breaks on the inside surfaces acceptable. During the second step, which is a test for soundness, the flattering shall be continued until the specimen breaks or the opposite walls of the specimen meet.


3. Hardness Test:

Samples from each lot of continuously heat-treated tubes & pipes are tested to ensure that the hardness is well within specified limits.


4. Eddy Current Test:

This test is carried out to detect any micro-cracks or inhomogeneities in the material, by using the test procedure as described in ASTM E-426 & SEP 1914.


5. Reverse Band Test:

A Sample of 4" in length shall be split longitudinally 90° on each side of the weld. The sample shall then be opened and bent around a mandrel with a maximum thickness of four times the wall thickness, with the mandrel parallel to the weld and against the original outside surface of the tube. The weld shall be at the point of the maximum bend. There shall be no evidence of cracks or overlaps resulting from the reduction in thickness of the weld areas by cold working.


6. Tensile Test:

The tensile test serves to determine the strength and ductile characteristics of the tubes & pipes i.e., yield strength, tensile strength and % elongation.


7. Hydro-Static Pressure Test:

All tubes & pipes manufactured by "SANTOSH" are Hydrostatic Pressure tested as per the required specification. Our Hydro-static pressure testing machine is capable of carrying out pressure tests up to 6000 psi. If required, a customer or deputed inspection agency can witness 100% Hydro-static pressure testing at our plant. The products can also be supplied with third party inspection like Lloyds, SGS, BVQL, PDIL, TUV, etc.
