Eddy Current Test

Eddy current testing is an important non-destructive testing method used to assess the quality and integrity of the tubes. This test involves passing an electrical current through the tube and detecting any electromagnetic changes that occur due to defects, such as cracks, voids, or variations in wall thickness. Eddy current testing helps identify any imperfections in the tubes, ensuring that only defect-free products are sent to customers.

Flaring Test

The Flaring test serves to establish the forming behavior of tubes & pipes which are expanded to a specific degree in respect of O.D. This test is carried out in conformation to the international standards.

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.

Hardness Test

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

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.

Crushing Test

Crushing tests are commonly used to assess the strength and durability of steel tubes, including CDW (Cold Drawn Welded) and CDS (Cold Drawn Seamless) steel tubes. These tests help determine how much load or pressure the tubes can withstand before they deform or fail.
