Our carbon steel flanges adopt a more stable production process, starting from the selection of high-quality raw materials.
Each batch of steel is rigorously tested to ensure compliance with standards,laying a stable foundation for production.
Our core technology lies in mature forging and machining processes.
The controlled forging technique is used to achieve the grain structure and strength, followed by precise CNC machining to ensure precise dimensions and perfect sealing surfaces.
Each flange has undergone heat treatment to enhance its mechanical properties, ensuring stable performance under pressure and at various temperatures.
The core of our quality commitment is the dual certification guarantee.
Both the materials and the finished flanges are professionally tested in accordance with the ASTM A270 standard.
This standard stipulates the performance requirements for seamless and welded austenitic stainless steel pipes,verifying key attributes such as corrosion resistance and mechanical strength.
In addition, each product comes with an EN 10204 3.2 type inspection certificate.
This official record issued by our independent quality department provides traceable evidence – including furnace numbers, chemical composition analysis,
and mechanical test results – proving that the flanges fully meet your order requirements and relevant international standards.
The combination of exquisite craftsmanship and certification verification ensures that our carbon steel flanges provide customers with reliability,
safety and compliance for the most demanding pipeline and pressure system applications.
