All the required tests and inspections are carried out in compliance with the customer requirements and related standards by using modern inspection and testing equipments.
* All tests required by API 5L standard are applied to the natural gas pipes.
* Manufactured from special quality steel bands.
* Ultrasonic and nondestructive tests are used.
* The physical, chemical and mechanical tests
* All pipes pass from 100% hydrostatic pressure test and the magnetic tests and controlled whether they leak or there is a fault in the metallographic structure of the pipe or not.

The oil pipes are used in the transportation of oil, fuel-oil, oil, natural gas and chemical liquid. All pipes pass from 100% hydrostatic pressure test and the magnetic tests and controlled whether they leak or there is a fault in the metallographic structure of the pipe or not. Some pipes supply with heat treatment.
