Our CTP (Glass Reinforced Plastic) production facility in Malatya reflects our commitment to engineering, quality, and sustainability—not just pipe production.
Every pipe produced here undergoes rigorous testing under extreme conditions:
- Exposed to temperature stress
- Tested for high-pressure resistance
- Examined for chemical durability
- Evaluated for long-term performance in humid environments
Tested in compliance with international standards such as TS ISO 1071, 7509, 10952, and 10468, we offer more than just pipes—we deliver longevity, trust, and quality.
Our Malatya facility is not only a manufacturing site but also a certified point of trust, where resilience is both tested and proven.
Here, product and raw material tests are executed with precision using advanced lab equipment, international test methods, and expert technical staff.

1. Resin Tests
Resin quality in GRP pipe production plays a critical role in overall product performance. Regularly conducted resin tests include:
Viscosity Test
- Purpose: Assess fluidity
- Significance: Affects saturation and fiber absorption during production
Gel Time Measurement
- Purpose: Determine solidification time
- Significance: Ensures controlled curing and process stability
Peak Time Measurement
- Purpose: Identify maximum heat during chemical reaction
- Significance: Used to validate curing profile and production compatibility
Solids Content (%)
- Purpose: Measure actual polymer content
- Significance: Directly impacts final mechanical strength
2. Glass Fiber Tests
Fiber quality directly affects mechanical performance and product longevity. The following tests are routinely conducted:
Visual Inspection
- Purpose: Detect deformations, cracks, moisture
- Significance: Ensures proper fiber distribution during production
Weight per Unit Area (g/m²)
- Purpose: Measure fabric weight
- Significance: Related to laminate strength and resin absorption
Moisture Control
- Purpose: Measure humidity in the fiber
- Significance: High moisture hinders resin bonding and weakens lamination
Tex (Linear Density)
- Purpose: Determine yarn density (g/1000 m)
- Significance: Critical for mechanical performance calculations
Loss on Ignition
- Purpose: Measure coating material on fibers
- Significance: Directly affects resin bonding quality
Note: Resin–fiber compatibility directly influences GRP pipe stiffness, flexibility, and chemical resistance. Therefore, every raw material batch is thoroughly tested and approved prior to production.
3. Sand Analyses
Sand is a key raw material in GRP pipe production, directly affecting strength and quality. Regular analyses at our Malatya CTP facility include:
Sieve Analysis
- Purpose: Determine particle size distribution
- Significance: Uniform grains ensure better resin bonding
Turbidity Analysis
- Purpose: Measure fine and soluble particles
- Significance: High turbidity can negatively affect bonding
Loss on Ignition
- Purpose: Identify organic and volatile components
- Significance: Affects purity and resin compatibility
Moisture Measurement
- Purpose: Measure water content
- Significance: High moisture may hinder bonding and cause deformation during production
Note: Each parameter in sand analysis plays a critical role in ensuring the final product is strong, high quality, and long-lasting.
4. Gasket Tests
Gaskets used in various pipe systems are crucial for leak-proof performance. At our Malatya CTP Facility, gasket quality is verified with:
Dimensional Control
- Purpose: Ensure compliance with standard sizes
- Significance: Incorrect sizes can lead to leakage and system inefficiencies
Hardness Test
- Purpose: Measure material hardness
- Significance: Ensures durability and effective sealing over time
