Gaskets serve as crucial sealing elements for various types of equipment, including pumps, pipe valves, pressure tanks, reaction tower kettles, and more. They are positioned between two flanges to enhance the seal and prevent leakage at the joint. TOPPER primarily offers two types of gaskets: metal gaskets and insulating gaskets (graphite gaskets, PTFE gaskets). The metal gaskets consist of spiral wound gaskets and metal ring gaskets, which are predominantly utilized in the petroleum, petrochemical, and food industries. Meanwhile, flange isolation kits are specifically designed for use in cathodic protection systems within pipelines.
The Flexible Graphite Gaskets Plant in China specializes in producing high-quality gaskets tailored to meet customer requirements. These gaskets are designed with a carbon content of 98%, ensuring excellent thermal and chemical resistance. They have a density of 1.0–1.1 g/cm³ and can withstand pressures up to 40 bar. The gaskets are available in a wide range of dimensions, from 1/2 to 60 inches, and can be customized to fit specific customer needs.
The Corrugated Graphite Gasket Manufacturer produces high-quality gaskets with a carbon or stainless steel core, covered with flexible graphite. These gaskets are available in sizes ranging from 1/2 to 60 inches and are designed for use in Class 150 and 300 LB applications. With a thickness of 2.38 mm, they offer excellent sealing performance and flexibility, making them suitable for a wide range of industrial applications where durability and reliability are essential.
