Quality control

How do we ensure every batch conforms?

On the production line
Outside diameter, wall thickness and length are monitored on every batch according to the standard applicable to the item.
Before shipping
Pipes are selected according to the standard and the intended use, and a tag is attached to every bundle confirming the product passed its tests.
Management systems
The factory holds ISO 9001:2015 (quality management) and ISO 45001:2018 (occupational health and safety); renewed copies are published on the Registrations & Credentials page as soon as they are received.
Specification sheets per item
Added to the item page when provided by the factory. Until then, the catalogue is the approved technical reference.
Transport, storage & installation guidelines

Protecting the product starts the moment it is received

  1. Transport from the factory

    Pipes are bundled in a timber frame and stacked alternately head-to-tail for easy loading. The number of pipes per bundle depends on the diameter, per the standard's tables. On site, pipes are not tipped off directly but unloaded by crane or alternately, and the spigot ends are supported on timber blocks no more than two metres apart to avoid bending.

  2. Handling on site

    Avoid impacts and direct sunlight, and do not leave pipes on the trench edge for long. Because of their weight, take care when lifting or lowering by hand, make sure the loading area is free of nails or sharp edges, and preferably use timber boards as protective bases. Keep the jointing rings carefully.

  3. Long-term storage

    In a warehouse or under a shade away from direct sunlight, on level ground or timber blocks, stacked alternately layer by layer, with the stack height between supports not exceeding five metres.

  4. Installation per the Saudi Building Code

    Follow the design and installation instructions for water, drinking-water and sewer pipelines, and the project consultant's instructions on soil type, laying depth and bedding above and below the pipe. Before installation, clean the rubber ring and the pipe thoroughly, make sure the spigot enters the socket and the two pipes are aligned, and use the dedicated pipe-jointing lubricant.

Warranty details and test procedures are confirmed by the factory in the official quotation for each project.
