HS855 PTFE coated gasket

HS855 PTFE coated gasket is turned PTFE as the coating material, lined with non-asbestos synthetic fiber, fluorine rubber Rubber, nitrile rubber, EPDM rubber and other soft materials, combined with PTFE excellent corrosion resistance and lining material good compression and rebound compensation performance, reducing the required bolt pre-tightening pressure. It is an economical sealing gasket.

HS857 serrated gasket

Product Introduction HS857 metal tooth gasket is a metal skeleton processed into equidistant, non-connected arc-shaped concentric grooves. The arc teeth can effectively simulate the deformation trend of the flange and ensure the efficient sealing of the gasket. The metal arc-shaped tooth gasket can also play a good sealing effect under small pressure, thus forming a metal skeleton with good elasticity; the upper and lower surfaces of the metal skeleton are compounded with a layer of graphite material or soft Teflon (ePTFE) and Non-asbestos and other strip-shaped sealing gaskets finally form the overall composite gasket. Due to the special structure of the corrugated composite gasket, it has a series of excellent properties. This product can be used in general applications, which is quite economical and effective. Can directly replace the winding gasket and coated gasket use. Suitable for high temperature and high pressure occasions such as pressure vessels, heat exchangers, valves, pipelines and other flange connection seals.

HS854 metal clad gasket

Metal coated gasket, the use of expanded graphite, ceramic fiber and other high heat resistance of inorganic filler as a filler, wrapped by a very thin layer of metal stainless steel, tinplate, copper and other materials of metal sheet, completely coated products. According to the gasket section, it is usually divided into plane type cladding and corrugated type cladding. It is the most traditional sealing gasket and is suitable for sealing of heat exchanger, pressure vessel, pump, valve and flange surface. However, the resilience is limited, requiring a flat flange surface and a high tightening force to achieve good results. It is suitable for sealing flanges of pressure vessels with large diameter (such as heat exchangers, reactors, etc.) and flanges of various media such as pumps, pipe valves, pipelines and various equipment.

HS85178-HR heat exchanger gasket

Heat exchanger gaskets are generally divided into tube heat exchanger gaskets and plate heat exchanger gaskets, the main role is to ensure that the heat exchanger in the heat exchange process of sealing, so as to ensure that the heat in industrial production from the higher temperature of the fluid to the lower temperature of the fluid temperature to meet the process requirements of the process to meet the needs of the process conditions. Heat exchanger gaskets are widely used in petroleum, chemical, electric power, metallurgy, shipbuilding, machinery, HVAC, food, pharmaceutical, aviation, environmental protection, urban heating and other industrial fields. Tubular heat exchanger gaskets are generally divided into tube box gaskets, floating head gaskets, tube box side gaskets, outer head cover gaskets and head cover gaskets. There are different gasket forms according to different tube passes. For multi-tube passes, different forms of ribs are generally required on the inner ring of the gasket (attached figure). Commonly used shell and tube heat exchanger gaskets are oil-resistant asbestos rubber gaskets, non-asbestos gaskets, graphite composite gaskets, metal wound gaskets, metal sheathing gaskets, metal tooth composite gaskets and so on. Plate heat exchanger gasket is a key part of the heat exchanger. As the application field of plate heat exchangers continues to expand, there are different requirements for temperature resistance, pressure resistance and corrosion resistance for different media and processes. The working temperature of the plate heat exchanger is actually the temperature that the sealing gasket can withstand. However, gaskets of different materials should be used according to different situations. The commonly used gasket materials include fluorine rubber, tetrapropylene fluorine rubber, EPDM, nitrile rubber, etc. The commonly used gasket cross-sectional shape is hexagonal. Plate heat exchanger gasket according to the installation method on the heat exchanger plate, can be divided into three forms: direct paste type, glue nail inlay type, buckle type.
