Description :
This product is an industrial grade neck flat welding flange (SO flange), made of high-quality stainless steel or carbon steel material precision forged. The surface has been finely machined to present a metallic luster and has excellent corrosion resistance and mechanical strength. The flange surface is flat and smooth, and the sealing water line is clear and regular, which can effectively enhance the sealing effect of the gasket and prevent medium leakage; The scientific design of the neck structure significantly improves the pressure bearing capacity and fatigue resistance of pipeline connections, making it suitable for pipeline system connections under medium and low pressure conditions.
The product is widely used in pipeline systems in the fields of petroleum, chemical, natural gas, electricity, shipbuilding, pharmaceuticals, food processing, and municipal engineering. It is used for reliable connections between equipment such as valves, pumps, and instruments and pipelines, or as a transition element for pipeline diameter reduction, branching, and closure. Its standardized hole spacing and bolt hole design ensure perfect compatibility with mainstream standard pipeline fittings such as national, American, and German standards, making installation convenient and maintenance cost-effective. The target customers include pipeline engineering contractors, equipment manufacturers, maintenance units, and industrial material purchasers. Supporting customization of different pressure levels (PN10-PN40), diameters (DN15-DN2000), and materials (304/316L/20 #/Q235B) to meet diverse engineering needs, it is a key foundational component for ensuring the safe, stable, and long-term operation of fluid conveying systems.
