|
|
Blaylock Gasket & Packing stocks a variety of styles and sizes of compression packing also known as mechanical packing. This material IS used in process industries such as petro-chemical, pulp and paper and steel mills, pharmaceutical, and chemical plants. This versatile sealing material is also used in service industries such as utilities, water and sewage plants to name just a few applications. Compression packing seals all kinds of fluids including but not limited to acids and alkalis, water steam, caustics, solvents, gases, oil and refined petroleum and many other chemicals over a range of temperature and pressure conditions. Mechanical packing is used to seal pumps, mixers, agitators, dryers, valves, and many other types of mechanical equipment. The proper material selection is based on, among other things, shaft speed, temperature and the particular medium to be sealed. We are always available to help you select the proper compression packing material for your application.
