Inner and outer ring metal graphite winding pad 1222 metal winding pad-It is made of alloy strip or stainless steel strip material, with graphite, asbestos, and PTFE as filling materialsMade of alternating spiral winding of "V" or "W" shapes. Spiral wound gaskets are used for static sealing in flange connections such as petroleum, chemical, mechanical, metallurgical, electrical, shipbuilding, pipelines, valves, pumps, pressure vessels, condensers, towers, manholes, and handholes. Due to its high mechanical strength, ease of use, and good compression resilience, it is more suitable for applications in severe temperature fluctuations. Material with inner and outer rings: OCr18N19SS304316316L Monel, pure titanium with outer ring, inner ring, basic shape. Graphite metal wrapped gasket with a usage temperature of -200-850 ℃ and a usage pressure of 0-20Mpa. Asbestos metal wrapped gasket with a usage temperature of -200-500 ℃ and a usage pressure of 0-25Mpa

Temperature for use of PTFE metal wrapped gasket-200-260 ℃ working pressure 0-10Mpa

The materials of the metal strip, soft packing, inner and outer positioning reinforcement rings that make up the spiral sealing gasket can be freely combined according to different media and operating conditions according to this table.

Precautions；1. The winding part of the gasket must be between the flange sealing surface, and the width of the winding part cannot be widened arbitrarily, which will inevitably affect the clamping force of the bolt and thus affect the sealing performance of the gasket.

2. Basic gaskets should not be used on concave convex flanges because under the axial compression force of the flange, the welding points on the inner ring of the gasket are prone to open, resulting in gasket failure. Operating temperature -200-260 degrees Celsius，pressure of use0-30 megapascals.3. Under harsh working conditions such as high temperature, cold or frequent alternation of hot and cold, large vibration, and strong corrosive media, it is recommended to install a reasonable material inner ring for gaskets used in flat flanges and convex flanges. 4. Low material gaskets should never be used to replace high material gaskets. Avoid gasket failure caused by material corrosion or other reasons. Due to its excellent chemical corrosion resistance, good self lubrication and non adhesiveness, polytetrafluoroethylene has excellent flexibility, resilience and excellent chemical corrosion resistance, and can be used in almost all chemical media. Suitable for sealing in fields such as petroleum, chemical, food, pharmaceutical, and power.
