PVC (Polyvinyl Chloride) pipes are among the most widely used products in Iran’s water supply, sewage, agriculture, and construction sectors due to their light weight, high chemical resistance, long service life, and cost-effectiveness. However, the quality and safety of PVC pipes strongly depend on compliance with recognized production standards. In this article, we examine the common standard for PVC pipe production in Iran and the role of reputable manufacturers in meeting these requirements.
Importance of Standards in PVC Pipe Manufacturing
Production standards ensure that PVC pipes:
- Can withstand specified pressure levels
- Are resistant to impact and corrosion
- Have a long operational lifespan
- Are safe for potable water and wastewater applications
Failure to comply with these standards may result in leakage, premature pipe failure, and high maintenance costs.
National Iranian Standard for PVC Pipes
The National Iranian Standard (ISIRI) is the primary and most widely used reference for PVC pipe production in Iran. The most important standard includes:
🔹 ISIRI 9119 Standard
This is the main standard for the production of rigid (U-PVC) pressure pipes in Iran. It specifies:
- Raw material requirements
- Pipe dimensions, diameters, and wall thickness
- Pressure classes (PN)
- Mechanical, impact, and hydrostatic pressure tests
Most urban and rural water supply projects in Iran require PVC pipes that comply with ISIRI 9119.
🔹 Other Relevant National Standards
Depending on the application, additional standards may apply, including:
- PVC sewer and drainage pipe standards
- PVC fittings and joint systems
- Material and quality control testing standards
Relation to International Standards
In addition to national standards, many reputable Iranian manufacturers align their production processes with well-known international standards, such as:
- ISO 1452
- DIN 8061 and DIN 8062 (German standards)
Compliance with these standards improves product quality and enhances competitiveness in domestic and export markets.
Role of Trusted Manufacturers in Quality Assurance
Established manufacturers such as Pars Polymer Company strictly follow national and international standards by utilizing modern machinery and advanced quality control laboratories. This commitment ensures:
- Certified and standard-approved products
- Acceptance in major infrastructure projects
- Long-term reliability and customer confidence
Conclusion
In summary, ISIRI 9119 is the most common and essential standard for PVC pipe production in Iran. Alongside international standards, it plays a vital role in improving product quality and safety. Choosing a reliable manufacturer such as Pars Polymer Company guarantees durable, high-quality, and standard-compliant PVC pipes for various applications.
