Description :
This product is a stainless steel blind plate (also known as flange cover) for steel pipe flanges that complies with HG/T 20592-2009 standard. It is mainly used for end sealing or reserved interface sealing of pipeline systems, and plays a role in isolating media, ensuring system safety, and facilitating maintenance. The product is made of S30408 (commonly known as 304 stainless steel) material, which has good corrosion resistance, oxidation resistance, and mechanical strength. It is suitable for various non corrosive media such as water, steam, oil, gas, etc.
From the picture, it can be seen that the blind plate is a neck flat welding structure (PL type), with evenly distributed bolt holes on the outer edge and a solid disk in the center. The surface has been machined with high smoothness and a flat sealing surface, ensuring a tight fit with the matching flange and preventing leakage. The edge is clearly marked with the words "ED HG/T 20592-2009 PL80 S30408", indicating its implementation standard, model specifications, and material grade, which facilitates engineering acceptance and traceability management.
Typical application scenarios include: sealing of pipeline terminals in chemical plants, sealing of inlet and outlet of water treatment equipment, isolation of clean pipeline systems in the food and pharmaceutical industry, and backup sealing of branch outlets in HVAC systems. The target users include procurement departments and equipment manufacturers in industries such as petrochemicals, electricity, shipbuilding, municipal water supply and drainage, and light industry machinery.
This product design follows national standards, with strict dimensional tolerances, easy installation, and can be disassembled and reused. It is an indispensable safety accessory in pipeline systems. Support customization of different pressure levels, diameters, and materials (such as 316L, duplex steel, etc.) according to drawings to meet diverse industrial needs.
