Used In Oil Field Industry Hydrogenated Nitrile HNBR Compound
Description:
With the development of petroleum industry and the continuous improvement of drilling depth,the requirements of sealing material rubber products are more and more stringent.
Nitrile butadiene rubber, which is commonly used in large quantities, is no longer sufficient.
Hydrogenated nitrile butadiene rubber can not be distinguished from other kinds of nitrile butadiene rubber in its basic properties, but it can be used in the harsh environment of oil field. In addition to petroleum, rubber products used in oil fields may come into contact with acidic gases such as hydrogen sulfide, as well as amine-containing compounds. Hydrogenated nitrile (HNBR) is well suited to the low temperatures of tens of degrees below zero due to the location of the field, as well as the adverse environments of high temperature and high pressure with the increase of drilling depth.
Heat resistance of hydrogenated nitrile:
Medium resistance of hydrogenated nitrile:
In addition, the acid and alkali resistance of hydrogenated nitrile has good stability in the harsh sodium at 100 ° C or diluted hydrochloric acid at 50 ° C.
High pressure resistance of hydrogenated nitrile:
Application of hydrogenated nitrile in oil field industry:
O-ring and other oil-resistant sealing rubber products: in the exploration and production process, the use of a large number of O-ring and other sealing ring sealing ring, they are not only in high temperature and high pressure oil contact, but also withstand the original contained in a variety of acid and alkaline substances and oil required chemicals (such as paraffin agent) corrosion. In the past, most of the products used nitrile butadiene rubber as sealing material.
By replacing it with hydrogenated nitrile butadiene rubber, the service life of the products can be greatly extended, which creates conditions for reducing the number of oil well shut-down and reduces the cost. ,
Extraction piston: In the past extraction technology, the carboxyl nitrile rubber is often used as the raw material for the extraction piston,
but the wear resistance and stability are not perfect. The service life of hydrogenated nitrile rubber is extended obviously.
Submarine conveying pipe: in the offshore oil production, in order to connect the oil well with the platform,it is necessary to use the tube bundle with certain flexibility, but this kind of flexible pipe must be resistant to various conditions such as high pressure and violent pressure drop and corrosion. At present, hydrogenated nitrile butadiene rubber is used as the first inner layer of the flexible pipe.
Explosion-proof tube: good elongation and constant elongation of hydrogenated nitrile are suitable for explosion-proof rubber products. The reliability and durability of hydrogenated nitrile as explosion-proof material have been greatly improved, which is of great significance to the safe production of oil field.
