The octagonal metal ring gasket is installed in the trapezoidal ring groove on the flange surface. When the connecting bolt is tightened, it is axially tightened and the upper and lower trapezoidal grooves are tightened, resulting in plastic deformation, forming an annular sealing belt and establishing an initial seal. After boosting under the action of medium pressure, the ring gasket radially expands. The gasket and the inclined surface of the trapezoidal groove are more tightly attached, resulting in a self-tightening effect.

Flange insulation group is one of the most common, effective and important connection forms in petrochemical plants, natural gas plants, offshore oil projects, etc. Various pipelines, pipe fittings, valves, instruments and equipment, flange insulation groups have unique performance and advantages. Use insulation kit seals on flanges to protect your pipes from the risk of leakage, sealing is achieved by the fit of flanges, insulating washers, bushings, washers, washers, bolts and nuts. Flange junction is connected and sealed to prevent medium leakage at the flange junction, as well as anti-corrosion and conductive insulation Protect.

The idea behind solid material is to use metals which cannot be punched out of sheets but are still cheap to produce. These gaskets generally have a much higher level of quality control than sheet gaskets and generally can withstand much higher temperatures and pressures.

Double-jacketed gaskets are another combination of filler material and metallic materials. In this application, a tube with ends that resemble a "C" is made of the metal with an additional piece made to fit inside of the "C" making the tube thickest at the meeting points.

Spiral wound gasket is an important sealing element. Metal spiral wound gasket is widely used in petroleum, chemical, metallurgy, power generation, shipbuilding and other industries. It is the key component of static sealing of pressure pipes, valves, pumps, heat exchangers and other equipment. part. Therefore, the selection and use of high-quality spiral wound gasket products is of great significance to reduce and eliminate running, running, dripping and leaking, and to ensure the safety of the host equipment and the normal operation of the pressure pipeline.

Graphite Gasket Flat gasket made of soft graphite, suitable for high temperature and strong corrosive media. Metal gasket There are three main types: 1. Octagonal and oval pads - suitable for trapezoidal groove flange sealing surfaces. 2. The tooth form is a bevel-shaped corrugation machined on the sealing surface of the metal flat gasket - suitable for the concave-convex flange sealing surface. 3. The lens gasket is suitable for the sealing surface of the lens flange, and the metal gasket is made of pure iron, extremely mild steel, stainless steel, aluminum and other materials.
