HS8512 Graphite Metal Wound Gasket B
Categorie:
Tags:
HS8512 graphite metal winding pad is made of thin steel strip and flexible graphite strip alternately wound, and its structural density can be different according to the locking force.
Requirements to produce, and the use of inner and outer steel rings to control its maximum compression, with good resilience, high temperature resistance, corrosion resistance, low leakage rate and other advantages.
Point, in the gasket category, its use temperature is higher. It is especially suitable for uneven load, easy relaxation of joint force, and periodic temperature and pressure.
An occasion of change, shock or vibration. Valves, pumps, heat exchangers, towers, manholes, hand holes and other flange joint static sealing components.
Widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other fields.
Product Introduction
HS8512 graphite metal winding pad is alternately wound with thin steel strip and flexible graphite strip. Its structural density can be made according to different locking force requirements, and the inner and outer steel rings are used to control its maximum compression. It has the advantages of good resilience, high temperature resistance, corrosion resistance, low leakage rate, etc. In the gasket category, its use temperature is higher. Especially suitable for uneven load, easy relaxation of joint force, temperature and pressure changes periodically, impact or vibration occasions. Valves, pumps, heat exchangers, towers, manholes, hand holes and other flange joint static sealing components. Widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other fields.
