1.Advanced equipment such as CNC lathes, high-precision milling machines, and flange-specific machining centers have been introduced, supplemented by a full range of quality inspection equipment including automatic flaw detectors, hardness testers, and dimension measuring instruments.

2.The production precision can reach ±0.02 mm. Strictly complying with national, American, and European standards, we implement full-process quality inspection from raw materials to finished products, with the defective rate kept below 0.3%.

1.High-quality raw materials such as carbon steel, stainless steel and alloy steel are carefully selected. We have direct cooperation with well-known domestic steel mills, and each batch of raw materials is accompanied by a material certificate.

2.A product traceability system has been established. Every stage from raw material warehousing, production and processing to finished product delivery is recorded and traceable, so as to prevent the practice of passing off inferior goods as high-quality ones.

1.We closely follow the technological trends of the industry, participate in the discussion of multiple flange industry standards, and are able to provide one-stop technical services such as process optimization, cost control and selection guidance.

2.Tailor-made flange solutions are provided for special working conditions (such as high temperature, high pressure and corrosion resistance) to help customers reduce costs and increase efficiency in their projects.

1.We hold a number of authoritative certifications, including ISO9001 Quality Management System Certification, Special Equipment Manufacturing License (TS), and API Certification.

2.We serve major enterprises such as CNPC, Sinopec, and CSCEC, with our products applied in municipal pipelines, offshore engineering, new energy projects and other fields.
