BV Mode II Recognition: Strengthening Manufacturing Quality Assurance

Bureau Veritas is an internationally recognized organization providing testing, inspection, certification, and classification-related services.

Under the BV Mode II Scheme, Luoyang Zhengyuan Petrochemical's manufacturing facilities and associated quality procedures have been assessed for the specified product categories.

This recognition provides additional supporting evidence of the company's manufacturing and quality management capabilities within the approved scope.

For international industrial customers, recognized manufacturing facilities and established quality procedures are important considerations when evaluating suppliers for technically demanding projects.

Recognition Scope: Copper-Nickel Alloy Components and Pressure Vessels

According to the certificate issued by Bureau Veritas Marine & Offshore, the recognition covers the following product categories:

Copper-Nickel Alloy Flanges

The recognition includes copper-nickel alloy flanges with a maximum nominal diameter of DN900.

Flanges are essential connection components in piping systems, enabling the assembly and maintenance of pipelines and equipment.

Copper-nickel alloys are used in selected industrial and marine applications where corrosion resistance and material compatibility are important considerations.

Copper-Nickel Alloy Pipe Fittings

The recognition includes copper-nickel alloy pipe fittings with a maximum nominal diameter of DN900 and a maximum thickness of 19 mm.

Pipe fittings are used to connect piping sections, change flow direction, and accommodate different pipeline configurations.

Their suitability depends on the applicable material specifications, pressure requirements, installation conditions, and relevant engineering standards.

Pressure Vessels

The recognition also includes pressure vessels.

Pressure vessels are widely used in industrial processes requiring the containment of liquids or gases under specified pressure conditions.

Their design, manufacture, inspection, and certification must meet the applicable requirements of the intended project and governing standards.

Supporting International Customer Requirements

For overseas customers sourcing industrial piping components and pressure equipment, supplier evaluation often involves manufacturing capabilities, technical specifications, quality procedures, and certification documentation.

The BV Mode II recognition represents an important step in Luoyang Zhengyuan Petrochemical's continuing efforts to support customer quality expectations.

Under the applicable BV requirements, products within the recognition scope are subject to the relevant individual or batch certification procedures.

The company will continue to focus on manufacturing quality, technical communication, and compliance with applicable project requirements.
