Stainless steel flanges 304/316 material sealing connection parts for chemical pipelines.

We specialize in customizing stainless steel flange parts. Relying on precision CNC technology to ensure that the flange end face is flat, the hole position is accurate, it has excellent sealing performance and high load capacity, and the connection is stable and durable.

Superior Properties of Stainless Steel Flange Parts

Stainless steel, with its excellent corrosion resistance, high strength, and superior high and low temperature performance, has become a key material for industrial piping connection systems. We employ advanced milling and turning technology to complete multiple processes such as flange sealing surface machining, bolt hole drilling, and beveling in a single clamping operation, ensuring the dimensional accuracy and geometric tolerances of the flanges. This innovative processing method not only guarantees product quality stability but also significantly improves production efficiency, making it particularly suitable for the batch customization needs of flange parts of various specifications.

Professional Selection of Diverse Stainless Steel Materials

We offer flange part processing services using a variety of stainless steel materials, including 304, 316, 321, and 310S. For different operating conditions, our process team provides professional material selection advice: 304 stainless steel has good overall performance and is suitable for conventional industrial piping; 316 stainless steel performs excellently in corrosive environments such as chemical and marine environments; 321 stainless steel is suitable for high-temperature working environments; and 310S stainless steel has better high-temperature resistance and is suitable for heat treatment equipment.

Precision Machining Technology Guarantees Success

We utilize large CNC vertical lathes, coupled with specially developed stainless steel machining tools and specialized fixtures, to ensure stability during the machining of large flanges. Through precise CNC system control, we can achieve IT7 level dimensional accuracy and Ra1.6 sealing surface roughness requirements. Especially in the machining of high-pressure flanges, we possess unique process technology that effectively guarantees the flatness and surface quality of the sealing surface, ensuring the reliable sealing of pipeline connections.

Comprehensive Quality Assurance System

We have established a rigorous quality inspection system, equipped with professional testing equipment such as high-precision coordinate measuring machines, spectrometers, and ultrasonic flaw detectors. Each stainless steel flange part undergoes strict dimensional inspection, sealing surface accuracy measurement, material composition analysis, and other quality checks. According to customer needs, we can also provide surface treatment services such as pickling and passivation, electropolishing, and sandblasting, which enhance the flange's corrosion resistance and improve the product's aesthetics.
