ASME B16.47 flange connection with the gasket

"ASME B16.47 flange" gasket, a machinery, equipment, spare parts for the pipeline as long as the seal fluid place is used, the outside inner-used material for sealing purposes. Flange gasket is a metal or non-metal plate-like material, the cutting, stamping or cutting process made, mechanical seal and seal between the pipe connection parts, machinery and equipment for the connection between. Press material can be divided into metal and non-metallic gaskets sealing gaskets. Metal, copper gasket, stainless steel gaskets, iron gaskets, aluminum gasket. Non-metallic, asbestos gaskets, non-asbestos gaskets, paper pads, rubber gaskets and so on. Below that development under the flange gasket connection with rubber seals at first said "ASME B16.47 flange" connected with rubber gaskets rubber material trends: special engineering elastomers low performance replace oil and rubber rubber materials Limit of modified low friction modification can be injection-molded rubber solid and liquid elastomers. Engineering plastics are becoming more important polytetrafluoroethylene (PTFE) having excellent low friction characteristics, its applications are quite extensive and mature. Adding PTFE in good mechanical strength engineering plastic composite material can give full play to the advantages of the two materials. Followed by "ASME B16.47 flange" connection with rubber gasket is generally high performance polyurethane material polyurethane materials can only be long-term in the following 80℃, after Parker-modified polyurethane can withstand high temperature 120℃, short-term It can be resistant to 145℃, excellent compression set performance. Infiltration modified with self-lubricating fluid (including MoS2 etc.) PU material, reducing the friction coefficient, to advance high-speed PU pneumatic and sealing applications. With the enhancement of environmental consciousness, the seal in an aqueous medium under conditions of increasing. A substantial increase from the hydrolysis resistance PU material material structure is necessary. Engineering ceramic seal further research applications (including Polymer) engineering ceramics has excellent chemical resistance and temperature resistance, with the development of sealing technology, it will have some application in the sealing element. In particular, engineering ceramics by polymer modified (so-called "polymer ceramics"), elasticity and toughness has been improved.
