Quality Policy

Several tests are carried out in Al Tamam Laboratories to ensure the compliance of the products to quality standards :

(§) Pressure Test is done to ensure that pipes are manufactured according to Saudi standard (14/151996) (675/1997) German Standard 8061 and American Standard ASTM D1785. Pressure varies depending on size and purpose of use.

(*) Impact test is subjecting pipes to a strikers weight, which is increased proportionately to pipe diameter.

Lab Testing Facilities

Al Tamam Factory for PVC Pipe and Fittings has state-of-the-art-equipments installed at the laboratory which is driven by well-qualified engineers since we view about high quality and advanced product range, and believe in supplying only superior quality products aimed at satisfying domestic and international customers.

We test our materials and products according to various national and international standards
