Laffan Pipes Factory
Quality Control and Assurance
Laffan Pipes Factory is committed to producing high quality corrugated pipe, which are manufactured in accordance with QCS, BS EN 13476-3 and the relevant standards related to corrugated pipe. We have control measures in place to ensure consistency and quality in our product. Our testing laboratory ensures that the characteristics of our pipe adhere to the standards, as well as meet customer specifications.
Our testing laboratory includes the following tests and quality control equipment:
|Up to 30% deflection
- Ring Stiffness & flexibility testing machine according to ISO 9969 and ISO 13968
- Joint Tightness testing machine according to EN 1277
- Impact testing machine according to EN 744
Ring Stiffness Test
The ring stiffness test is used to determine the pipe’s resistance to external forces. A 3% diametric deflection of the internal diameter is applied to the pipe and the stiffness can be calculated in accordance with ISO 9969.
Ring Flexibility Test
The ring flexibility test is a continuation of the ring stiffness test, except that a 30% diametric deflection is applied to the pipe. The purpose of this test is to see if the pipe maintains its structure under strenuous conditions.
Impact Test Machine
The impact test is tested in accordance with EN 744. The purpose of this test is to determine if the pipe cracks when impacted by a given weight at a 2 meter height. The test is deemed to have passed if there are no visible cracks in the pipe.
Joint Tightness Test
The joint tightness test is a test which measures the tightness of the EPDM rubber gasket at a vacuum pressure. If no leak occurs, then the test is said to have passed.
