stainless steel plate flange

Product Description

Stainless steel plate flat welding flange (also known as slip-on flange) is one of the most commonly used connecting fittings in pipeline systems. It features a flat plate structure with or without a neck, and is fixed by inserting the pipe into the flange inner hole and welding, realizing the detachable sealing connection between pipes, valves, equipment and pipelines. Made of high-quality stainless steel and produced in strict accordance with international and domestic standards such as ASME B16.5 and GB/T 9119, this product has the advantages of simple structure, convenient processing, economical cost and stable sealing performance. It is widely used in medium and low pressure fluid transmission scenarios such as petrochemical industry, municipal water supply and drainage, food and pharmacy, HVAC, etc., and is a core basic component for industrial pipeline layout.
