Laboratory
Tests at every stage
From incoming resin to finished pipe — every batch is checked in Al-Tamam laboratories before release.
Stage 2
Final product
- Pressure test (§)
- Impact Test (*)
- Chemical Resistance Test (Sulphuric Acid)
- Heat Reversion Test (Shrinkage)
- Water Absorption Test
- Resistance to environmental conditions
- (Extrusion) Methylene chloride test
- Tensile Strength test
- Elongation at break test
- HDT / VSP / Vicat test
- Opacity Test
Pressure test confirms pipes are manufactured to Saudi standards SASO 14/15 (1996) and 675/1997, German Standard DIN 8061, and American Standard ASTM D1785. Pressure varies depending on size and purpose of use.
Impact test subjects pipes to a striker weight increased proportionately to pipe diameter, verifying resistance per national specifications.

Performance
Pressure–temperature relationship
Allowable working pressure declines as liquid temperature rises. Classes 2–5 are charted for design reference across typical service temperatures.
Production
Manufacturing process flow
From incoming materials through extrusion, quality control, packing, and delivery — each batch is verified before dispatch.
-
Incoming
Raw materials arrive and are received at the factory.
-
Raw material store
Resin and compounds are held under controlled storage.
-
Mixing
Base materials are blended with additives for the required formulation.
-
Silo
Mixed compound is transferred to silo storage ahead of extrusion.
-
Extrusion
Compound is melted and formed into continuous pipe.
-
Pulling
Pipe is drawn through the line at controlled speed.
-
Parting
Continuous pipe is cut to specified lengths.
-
Forming
Ends are formed (socket / bell) as required.
-
Q.C.
Quality control checks are completed before packing.
-
Finish goods store
Accepted product is stored ready for dispatch.
-
Dispatch
Orders are loaded and delivered to customers.
