Stainless Steel Blind Flange (also known as Flange Cover, Blank Flange) is a solid flange disc with no central bore. Its core function is to seal the end of pipelines and block pipeline systems, and it can also be used for temporary isolation during equipment maintenance, pipeline pressure testing, etc. Our blind flanges are made of high-quality stainless steel (304/316/316L optional), manufactured through precision forging, CNC machining and surface polishing processes. They feature excellent corrosion resistance, high temperature resistance and pressure-bearing capacity, suitable for pipeline systems in chemical, petroleum, water supply and drainage, food and pharmaceutical, environmental protection and other industries. Complying with domestic and international standards such as ASME B16.5, GB/T 9119, HG/T 20592, we also support customized non-standard sizes.

Stainless Steel Weld Neck Flange (referred to as WN Flange) is a core high-pressure connecting pipe fitting in industrial piping systems. Its core feature is a tapered long neck butt-welded to the pipeline, with uniformly distributed bolt holes on the disc body, which is tightly connected with another flange through bolts to achieve sealed connection. The product is integrally forged with high-quality stainless steel materials, manufactured in accordance with international general pipeline standards, and has excellent corrosion resistance, structural strength and sealing performance. It is the preferred connecting piece for working conditions with high temperature, high pressure and large fluctuations of temperature/pressure, and is widely used in fluid transmission piping systems in harsh fields such as petrochemical industry, shipbuilding & ocean engineering and power energy.

Stainless Steel Socket Weld Flange (SW Flange) is a critical connecting component for small-bore high-pressure piping systems. The pipe is inserted into the flange socket and secured by fillet welds, featuring compact structure, robust connection, and reliable sealing. It combines high strength with easy installation, designed for harsh conditions in chemical, petroleum, power, pharmaceutical industries.

Stainless Steel Loose Flange (also known as Loose Expansion Joint) is a high-pressure pipeline fitting with a floating connection design. Its unique structure features a flange ring that is loose around the pipe rather than welded directly, compressing against the sealing surface. Thanks to its exceptional compensation capability and corrosion resistance, it is ideal for high-pressure, high-purity pipeline systems that require frequent cleaning, sanitization, or have strict requirements for thermal expansion and contraction.

Crafted from high-quality stainless steel through forging process, our stainless steel threaded flanges are specially designed for medium and low-pressure piping systems. Featuring welding-free and quick installation, they are perfectly suitable for pipeline connection in various non-welding, explosion-proof and special working conditions. With excellent corrosion resistance, sealing performance and stability, they are ideal pipeline accessories for chemical industry, water treatment, shipbuilding, instrumentation and other fields.

Stainless steel slip-on flange with neck (also known as SO flange) is the most widely used flange connection accessory in stainless steel pipeline systems. It adopts a necked slip-on structure, with the neck and flange disc integrally formed, and is fixed to the pipe by fillet weld. Made of high-quality stainless steel and produced in strict accordance with international general standards, this product combines excellent sealing performance, structural strength and easy installation, which can effectively realize the detachable connection of pipes with valves, equipment, instruments and other components. It is a core connection accessory for pipeline systems in petrochemical, municipal engineering, food and pharmaceutical and other fields.

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.
