The Company has its own Laboratory and complete set of testing equipment with qualified and competent quality control staff.

The followings are the regular tests performed as a part of our quality control procedure.

1. Regular testing of raw material
2. Concrete crushing tests
3. Tests on Lining
4. Spark tests

To ensure high quality of manufactured pipes, the following testing methods as provided in SASO, ASTM C-479 and BS 5911 are used:-

External Load Crushing strength Test:This test is performed to prove that the pipe has sufficient strength to withstand the external crushing load as stated in ASTM or BS specifications. The test carried out on one sample pipe selected at random from a lot of the same nominal diameter and the test results shall conform to the requirement for the acceptance of the Lot. The testing procedure is as described in ASTM C-76M under "Three edge Bearing Test".

Hydrostatic Test: This test is performed to check pipe leakage and to ensure the extent of leakage if any, is under specifications. This test is carried on a sample pipe selected at random from a lot of same nominal diameter and the result shall conform to the requirement for the acceptance of the lot. In this test, sample pipe is placed in the testing machine and filled with water to exclusion of air and then water pressure is brought to specified pressure for specified period without sweating or leakage.
