SNI 39:2024: Updated Steel Pipe Standard for Water Pipelines and Gas Installations

The transition from SNI 0039:2013 to SNI 39:2024 marks an important update for the steel pipe industry in Indonesia. This update is not limited to a change in the standard number. It also covers a broader range of pipe applications, improvements to the certification process, and stronger requirements for quality control and product compliance.



SNI 0039:2013 on Steel Pipes for Water Pipelines With or Without Zinc Coating is no longer valid. Meanwhile, SNI 39:2024 on Steel Pipes With or Without Zinc Coating for Water Pipelines and Gas Installations was established on October 7, 2024, and is currently in force.

The mandatory implementation of SNI 39:2024 is regulated under Minister of Industry Regulation No. 5 of 2025. The regulation took effect on July 24, 2025, replacing the previous provisions that still referred to SNI 0039:2013.

What Are the Differences Between SNI 0039:2013 and SNI 39:2024?

• The Scope Now Covers Water Pipelines and Gas Installations

The most visible change can be found in the title and scope of the standard. SNI 0039:2013 focused on steel pipes with or without zinc coating for water pipelines. Under SNI 39:2024, the scope has been expanded to explicitly include gas installations.

This broader scope makes SNI 39:2024 more relevant to the increasingly diverse requirements of utility, construction, and infrastructure projects. However, this does not mean that one type of pipe can automatically be used for every gas system. Product selection must still consider:

• the type of fluid;
• working pressure;
• pipe diameter and thickness;
• connection method;
• operating conditions; and
• the project’s technical specifications.

Compliance with SNI is therefore one of the key considerations in material selection, but it is not the only factor that determines the reliability of an installation.

• Mandatory SNI Implementation Now Refers to the Latest Regulation

SNI requirements for steel pipes used in water pipelines were previously made mandatory under Minister of Industry Regulation No. 11 of 2016. 

However, that regulation still referred to SNI 0039:2013. It was later revoked and replaced by Minister of Industry Regulation No. 5 of 2025, which specifically makes SNI 39:2024 mandatory for steel pipes used in water pipelines and gas installations. The latest regulation covers several important aspects, including:

• the scope of products required to comply with SNI;
• conformity assessment;
• issuance of SNI Certificates;
• approval for the use of the SNI mark;
• responsibilities of manufacturers and business operators;
• product supervision; and
• transitional provisions.

For manufacturers, importers, and distributors, SNI compliance is not limited to meeting technical product specifications. It is also part of regulatory compliance when manufacturing, importing, and distributing steel pipes in Indonesia.

• Certification Uses a Type 5 Certification System

Conformity assessment under SNI 39:2024 is conducted through a Type 5 certification system. This system does not rely solely on testing a single product sample. The assessment also includes an audit of the production process, implementation of a quality management system in accordance with ISO 9001:2015, and testing to verify that product quality complies with SNI requirements. In general, the certification process includes:

• submitting a certification application;
• reviewing document completeness;
• auditing the management system and production process;
• collecting product samples;
• conducting laboratory testing;
• reviewing the audit and test results;
• issuing the SNI Certificate;
• approving the use of the SNI mark; and
• conducting periodic surveillance.

This approach is intended to ensure that compliance is not only demonstrated by the tested product sample, but is also consistently maintained throughout the production process.

• Production Process Control Becomes an Essential Requirement

SNI 39:2024 places the production process as an important part of conformity assessment. Quality control cannot be performed only after a pipe has been produced. Manufacturers must also control the stages that may affect product quality, from the receipt of raw materials to the final product inspection. These stages may include:

• raw material inspection;
• pipe-forming processes;
• ERW or SAW welding;
• dimensional adjustment or sizing;
• zinc coating processes for galvanized pipes;
• pipe cutting;
• dimensional inspection;
• quality testing; and
• production documentation.

Through structured production control, non-conformities can be identified earlier instead of being discovered only after the product has arrived at the project site.

• Product Certification and Traceability Become Increasingly Important

Under mandatory SNI implementation, manufacturers or business operators must obtain an SNI Certificate and approval to use the SNI mark before applying the mark to their products.

Product documents and identification are important because they allow users to verify whether the pipes received correspond to the specifications offered. Verification should not be based only on the word “SNI” printed on the pipe surface. The information should also be matched with supporting documents, including:

• the SNI Certificate;
• SPPT SNI;
• the mill certificate;
• product specifications;
• dimensions and thickness;
• pipe class; and
• relevant test results.

This level of traceability helps contractors, consultants, distributors, and project owners conduct material verification more systematically.

SPINDO Steel Pipes Have Been Updated to Comply With SNI 39:2024

In line with the updated standard, SPINDO steel pipe products that fall within the scope of SNI 39:2024 have been adjusted to comply with the latest requirements for steel pipes with or without zinc coating used in water pipelines and gas installations.



These adjustments are not limited to product specifications and quality control. They have also been applied to the marking on each pipe length. SPINDO product markings have been updated to include the latest SNI reference and relevant product identification information. The marking may include:

• the manufacturer’s identity or brand;
• the latest SNI number;
• pipe class;
• nominal diameter and length;
• nominal thickness for sizes where it is required;
• the welding type or method; and
• the applicable certification code.

SNI 39:2024 requires marking information such as the manufacturer’s identity, pipe class, nominal diameter, length, nominal thickness for pipes above specified sizes, and the welding method. SPINDO’s internal materials also record adjustments to the SNI number, LSPR code, pipe class code, manufacturing method, and product identification included in the latest marking.

Clear product markings make it easier for customers, distributors, contractors, and project owners to conduct an initial verification of pipe identity and specifications. The information can then be matched with the mill certificate, SNI Certificate, SPPT SNI, and other quality documents.

This update reflects SPINDO’s commitment to keeping pace with developments in national standards and providing products with clear and traceable information.

Summary of the Differences Between SNI 0039:2013 and SNI 39:2024

The Impact of SNI 39:2024 on the Steel Pipe Industry

• For Manufacturers

Manufacturers must ensure that their facilities, production processes, quality management systems, testing equipment, and documentation comply with the applicable requirements. Production consistency is now as important as the final product test results.

• For Distributors

Distributors must ensure that the products they market are traceable and supported by the appropriate documentation. Product identification should not be based only on the brand, surface appearance, or price.

• For Contractors and Consultants

Technical specifications and procurement documents should be updated if they still refer to SNI 0039:2013. Contractors and consultants must also ensure that the selected pipes are suitable for the intended application, working pressure, dimensions, and project requirements.

• For Project Owners

Using pipes that comply with the applicable standard helps support procurement compliance, consistent material quality, and easier product verification. However, installation reliability is still influenced by system design, specification selection, installation methods, connection quality, inspection, and operating conditions.

How to Check Steel Pipes That Refer to SNI 39:2024

Before selecting or receiving steel pipe products, several aspects should be checked:

• Ensure that the procurement documents refer to a standard that is currently valid.
• Verify that the pipe is suitable for the intended water pipeline or gas installation application.
• Match the pipe diameter, thickness, and class with the project specifications.
• Check the product marking and information on the pipe.
• Match the product information with the mill certificate.
• Ensure that the SNI Certificate and SPPT SNI correspond to the product being offered.
• Review whether additional testing is required based on the project conditions.

These checks are important because a product bearing the SNI mark must still be used according to its intended purpose and technical limitations.

Conclusion

The transition from SNI 0039:2013 to SNI 39:2024 introduces important updates for the steel pipe industry in Indonesia.
