PTFE gasket is based on PTFE as the main material. Because PTFE itself has good corrosion resistance and stable physical properties, it is used in steel power, petrochemical and other industries.
industry has been widely used. Combined with the characteristics and working conditions of the petrochemical industry mentioned below, it is required to use PTFE gaskets or other sealing products with good quality and excellent chemical performance, so as to ensure
Safe and efficient operation of the equipment.
First of all, the price of raw materials for chemical products is relatively high, and any leakage will bring great losses to users. Chemical products are more flammable and explosive, once the leakage is likely to cause explosion, fire
disasters, casualties and other incalculable serious losses. In order to be able to safe production, the user's choice of seals is more careful, than quality, than brand, than service.
Secondly, the medium in the petroleum, petrochemical and natural gas industry is mostly a variety of liquids and gases with different corrosiveness, such as aromatics, rust inhibitors, acid gas, drilling fluid, seawater, carbon dioxide, hydrogen sulfide, etc.
And these media are often mixed together and have the characteristics of high temperature and high pressure, so the use of PTFE gaskets and other sealing products have excellent quality and good chemical properties, so as to protect
Safe and efficient operation of the equipment.

Let's look at the working conditions of the chemical industry:
Temperature: most of the high temperature, most of the normal temperature.
Medium: concentrated acid, high alkalinity, strong corrosiveness, high slurry concentration, high quality requirements for seals such as PTFE gaskets.
Pressure: part of the pressure is higher, the hardness, elasticity, toughness of the seal requirements are different.
Line speed: the water pump is around 2900 r/min.
PTFE gasket is suitable for sealing parts with severe alternating temperature and pressure. It is a static sealing element for flange connections such as pipes, valves, pumps, heat exchangers, towers, manholes, and hand holes.
