Quality & Testing

At Pinoplast, quality isn't an afterthought. It is embedded in every pipe we produce.

Quality That Runs Deeper

From raw material selection to final inspection, our quality management system makes sure every product meets Egyptian and international standards. Our multilayer technology, including glass fiber reinforced and UV-stabilized pipes, delivers strength, durability and long-term reliability, and we keep investing in innovation so you can trust every installation.

How We Test

Every stage is checked in our own laboratory before a product leaves the factory.

Raw Material

Melt flow index, moisture and density of the polypropylene random copolymer.

During Production

Visual appearance and dimensions, checked continuously by experienced technicians.

Finished Pipes and Fittings

Surface finish, dimensions, internal hydrostatic pressure, heat reversion and burst strength.

Assembled Pipeline

Hot and cold water cycle test.

Independent Verification

Beyond our own laboratory, we send product samples to independent national bodies to confirm compliance: the Plastic Technology Center, the Egyptian Organization for Standardization and Quality (EOS), the National Research Centre, the Chemistry Administration and the Central Metallurgical Research and Development Institute.

Pre-Delivery Testing

On request, our team pressure-tests your piping installation to verify its integrity before you put it into service.

Where

On site, after assembly is complete.

Test Pressure

1.5 × the highest planned operating pressure.

Duration

A 30-minute initial check, then a 2-hour verification.

Pass Criteria

No leaks, and a pressure drop of no more than 0.6 bar in the initial check and 0.2 bar over 2 hours.

Why Testing Matters

Prevents Failures

Catches leaks before they cause downtime or damage.

Ensures Safety

Confirms the system can handle its operating pressure.

Protects Your Investment

Finds weak points early, avoiding costly repairs later.

Gives Peace of Mind

You receive a verified, ready-to-use installation.

Our Process

We test on site once assembly is complete, after three preparation steps.

1. Secure

Close all valves and cap every open end.

2. Fill

Fill the system slowly, venting air at the highest points to prevent pressure surges.

3. Isolate

Test each pipeline section separately for precise fault detection.

Pressure Test Protocol

We apply 1.5 × the system's maximum operating pressure in two stages.

Stage 1 — Initial Check (30 minutes)

The test pressure is restored after the 10th and 20th minutes. Pass: the pressure drop does not exceed 0.6 bar and there is no leakage at any point.

Stage 2 — Extended Verification (2 hours)

The test pressure is held for a further 2 hours. Pass: the pressure drop does not exceed 0.2 bar and there is no leakage at any point.

If the Pressure Drops Too Far

A leak is present. The affected section is repaired, re-welded or retightened, and the test is repeated from Stage 1.

Final Commissioning

After a passed test we recommend three last steps.

Flush

Clean all lines to remove debris.

Drain

Close and empty unused branches so water does not stand in them.

Record

Keep the test date, pressures, duration and the responsible engineer's name with the handover documents.
