In December 2025, CANGZHOUS KH FITTINGS CORP. successfully completed a two-day on-site audit for PED (Pressure Equipment Directive) certification. A team of experienced auditors conducted a comprehensive assessment of the company's quality management system and key production processes according to strict PED standards and CE certification requirements.
 

The audit team performed a thorough evaluation of KH's quality management system over the two-day period based on a detailed pre-established plan. The examination covered all aspects of quality management, including sales and contract management, purchasing and supplier management, production control, inspection, and laboratory management.
 

 

Technical specifications, process documentation, and on-site production management related to stainless steel threaded pipe fittings and valves underwent in-depth verification by the audit team. Particular attention was paid to raw material quality control and critical processes such as welding and non-destructive testing.

 

The PED (Pressure Equipment Directive) certification is a mandatory regulation​ in the European Union, enacted to ensure the safety of pressure equipment. This directive was adopted on May 29, 1997, and came into effect on November 29, 1999. It applies to pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar, including vessels, piping, safety accessories, and pressure accessories.

 

With PED certification, KH's products can bear the CE marking, indicating compliance with the essential safety requirements of the relevant EU directives and enabling free circulation within the EU market, eliminating the need for repeated certifications in different member states.
 

The successful PED audit establishes a solid foundation​ for KH to expand its presence in international markets. The EU implements strict supervision and management of CE certification, with relevant authorities regularly conducting spot checks on products in the market to ensure ongoing compliance with certification requirements.

 

For pressure equipment manufacturers, PED certification serves not only as proof of product safety but also demonstrates the company's quality management capabilities and technical expertise. It signals to the international market that KH possesses the ability to produce high-quality pressure equipment that meets international standards.
 

KH plans to use this audit as an opportunity to continuously optimize its quality management system. According to PED requirements, companies must establish and maintain a comprehensive quality management system​ that ensures compliance with standards throughout the entire process from design and manufacturing to inspection.

 

For core products such as stainless steel threaded pipe fittings and valves, the company will continue to strengthen quality control to enhance product reliability and market competitiveness. PED certification represents not an endpoint but a new starting point for quality management efforts.

 

The audit report is currently in its final preparation stage. The company anticipates positive results from this audit and has expressed commitment to using this opportunity to continually refine its quality management system, providing customers with more reliable products and services.
