Laboratory & Quality Control

Polymer and PE pipe testing unit.

Luleh Bukan Laboratory is the factory's independent polymer and pipe testing unit. It performs 16 tests across three product families — polyolefin pipes and fittings up to 630 mm, polyethylene pipe, and unplasticized PVC pipe — each to a named national and international method standard. It both monitors production and tests samples commissioned from outside.
