Composite materials
ELT142 packing rings are molded from low-sulfur expanded graphite, with precise dimensions and controllable density, and without any added fillers or binders. The graphite purity is greater than 98%, eliminating the need for further anti-corrosion treatment. Generally, the cross-section of the packing ring is square, but it can also be wedge-shaped or V-shaped, the latter two being suitable for high-pressure applications. Molded from pure flexible graphite with a metal liner, reinforcing materials such as stainless steel foil, mesh, or others are effective. To prevent slow oxidation of the packing, a design with stainless steel end caps is necessary. Corrosion inhibitors added as sacrificial anodes effectively protect the stem and packing. It possesses the characteristics of expanded graphite and can withstand severe...
Graphite corrugated tape (with adhesive)
Graphite corrugated strip - Graphite sheet is cut into strips using a high-precision lathe, and then rolled into a corrugated shape by a special textured roller, called expanded graphite corrugated strip. Model ELT141 is a self-adhesive backed graphite corrugated strip. Compared with traditional graphite slitting machines, lathe processing will not damage the graphite roll material. It is often used as a filling material for winding gaskets, and for making expanded graphite packing rings, and as a gasket in emergency maintenance. With self-adhesive backing, it is easy to install. When used as a packing gland packing, the graphite strip is directly wrapped around the shaft of the pump or valve, and after winding to a certain size, it is pressed with a pressure cover. For small diameter valves
