A Gasket is made of paper, rubber or copper, placed between the two planes to strengthen the sealing material, to prevent fluid leakage between the sealing elements of the cover.
Gaskets are mechanical seals between two objects. They are usually used to prevent pressure and corrosion between two objects, and naturally expand and shrink in the pipeline. Because machined surfaces can not be perfect, the use of gaskets can fill the irregularity. Gaskets are usually made of sheet material, such as pads, rubber, silicone rubber, metal, cork, felt, chloroprene rubber, NBR, glass fiber or plastic polymers (such as polytetrafluoroethylene). Asbestos may contain asbestos for specific applied gaskets.
A gasket is a leak (usually in the middle) of a thin plate (usually in the middle), usually used for the distribution of load thread fasteners. Other uses are spacers, springs (Baer vill gaskets, wave gaskets), wear resistant pads, pre display devices, locking devices. Rubber gaskets are also used in faucets (valves) to cut off flowing liquids or gases. Rubber or silicon gaskets can also be used to reduce fan vibration. Usually the outer diameter of the gasket is about two times the diameter of the inner diameter.
Gaskets can be classified into non-metallic gaskets, metal gaskets and metal nonmetallic gaskets according to their material and structural characteristics, and they can be subdivided into several types.

Under the influence of multiple favorable factors, the province's auto production resumed rapid growth. According to information from the Provincial Economic and Trade Commission, in March, the province’s vehicle output exceeded 100,000 units for the first time, reaching 120,372 units, setting a record high in the province.
Since the beginning of this year, the production and sales of automobiles in our province have gradually recovered. Heavy trucks, light goods vehicles, mini trucks, SUV passenger cars and mini-buses have achieved good growth, and the production situation of major key enterprises has been good. In March, CNHTC produced 18,123 heavy-duty vehicles, an increase of 17.90% year-on-year, and monthly production reached the highest level in history. In the first three months, CNHTC has produced 32,747 heavy-duty vehicles, with a domestic market share of 31.29%, ranking the first in the industry in the country. Statistics show that from January to March, the province produced a total of 275,257 vehicles, an increase of 15.37% year-on-year.
The relevant staff of the Provincial Economic and Trade Commission analyzed that March was the traditional peak season for automobile sales, together with favorable factors such as the country’s expansion of domestic demand, stimulation of consumption, and the start-up of a large number of infrastructure construction projects, which strongly promoted the improvement of the automobile production and sales situation in our province.

Non metallic gaskets non-metallic gasket are made of gaskets made of asbestos, rubber, synthetic resin, polytetrafluoroethylene, etc.
A non-metallic gasket non-metallic jacket gasket is coated with a non-metallic gasket, such as synthetic resin.
Semi metal gaskets semimetallic gasket gaskets made of metal and non-metallic materials, such as wound gaskets and metal gaskets. A spiral wound gasket spiral wound gasket consists of gaskets made of spiral belt wrapped by metal belt of V or W section.
1) inner ring inner ring is installed in the inner ring of the winding gasket metal ring.
2) outer ring outer ring is mounted on the metal ring of the outer ring of the wound gasket. B metal coating
Metal gaskets metallic gasket are gaskets made of steel, aluminum, copper, nickel or Monel alloy.
Winding gasket is a gasket with metal band (generally V type steel strip) and non-metallic belt twisted into ring. It is intertwined alternately with non-metallic belt. Because of its good elasticity, it is widely used in the flange seal structure of petrochemical, chemical, electric and other industries. The inner layer or outer layer of the gasket can be added to the steel ring according to the specific position. Position or strengthen.
