Product details
Performance characteristics:
The high-purity graphite core treated with corrosion inhibition is reinforced with 5 stainless steel wires, greatly improving the anti extrusion ability of graphite. It is more suitable for steam sealing under high temperature and high pressure than traditional graphite packing, and can be applied to all steam valves, steam turbines, general valves, expansion joints, high-temperature slide valves, and low speed condensate pumps, especially suitable for power plants, etc. According to customer requirements, it can be molded into high-temperature and high-pressure special packing rings such as ZD-RP1106
Product specifications: 3 * 3mm-70 * 70mm; Special specifications or various non-standard products can be customized according to customer requirements.
Equipment:
Suitable for packing sealing of valves, kettles, and pumps with high temperature, high pressure, and low line speed.
Industry:
Recommended for use in petroleum equipment, power plants, chemical industries, steel mills, etc.
Medium:
Except for a few strongly oxidizing media, it can be used for almost all media such as sealed hot water, high temperature, high-pressure steam, etc.
Product specifications: 3 * 3mm-70 * 70mm; Special specifications or various non-standard products can be formulated according to customer requirements
