PACKING PACKING

GOST 5152 - 84

DESCRIPTION AND CHARACTERISTICS

 


Braided stuffing box packing is the most common type of sealing material used to fill stuffing box chambers of valves, centrifugal and piston pumps, and various devices. More than 70% of pumps and 80% of fittings are equipped with these packings. They differ both in the materials from which they are made and in the methods of manufacture (structure). Both of these factors significantly affect the performance of the packings.

 

According to the technical documentation, the stuffing box packing, of which  GOST 5152 - 84 is fixed in the relevant acts, is divided into non - asbestos (developed on the basis of bast and cotton fibers) and asbestos. GOST also fixes the limit values, sliding speed, temperature, pressure, regulated for each brand of packing.

All packings containing asbestos are marked with the letter "A". By the type of packing, they are impregnated with fluoroplastic suspension, graphite - glue and fatty compounds, as well as dry (graphite or clean). It is not surprising that in chemistry, power engineering, processing, gas and oil production, stuffing box graphite , produced on the basis of thermally expanded graphite, is actively used .

 

Преимуществом сальниковых набивок является не только превосходная изоляция. Их использование позволяет значительно продлить срок службы разных механизмов. Они являются незаменимыми для:

  • Уплотнения неподвижных механизмов,
  • Трубопроводов,
  • Подвижных элементов электрических механизмов.

Главной особенностью сальниковой набивки является возможность функционирования в разных средах. Они сохраняют свое качества как в воздушной среде, в газах, воде и углеводородной среде, в нефтепродуктах, щелочах, кислотах и других материалах в жидком или газообразном состоянии. В зависимости от среды будет меняться допустимые предельные температура, давление и скорость скольжения.
