What is the maximum operating pressure for Joint gasket GOST, NBR used with symmetrical joints per GOST 28352-89 and 2217-66 at -10Â°C to +80Â°C?

Joint gasket GOST, NBR Format . Maximum operating pressure for symmetrical joints per GOST 28352-89 and GOST 2217-66 at -10Â°C to +80Â°C is typically up to 6.4 MPa (64 bar). Notes: - This value corresponds to common application limits for NBR gaskets in these GOST-standard symmetrical joint designs; actual allowable pressure may vary with joint diameter, flange class, surface finish and specific gasket cross-section. - For critical or higher-pressure applications verify with manufacturer datasheet or perform calculations per the specific GOST standard and joint parameters.

What chemical compatibility considerations apply to Joint gasket GOST, NBR for symmetrical joints per GOST 28352-89 and 2217-66 at -10Â°C to +80Â°C?

Joint gasket GOST, NBR Format For NBR (nitrile) gaskets used in symmetrical joints per GOST 28352â89 and 2217â66 at â10Â°C to +80Â°C, key chemical compatibility considerations: - NBR resists aliphatic hydrocarbons, oils, greases, hydraulic fluids (mineral oil based) and fuel oils; suitable for many petroleumâbased media within the temperature range. - Poor resistance to aromatic hydrocarbons, ketones, esters, chlorinated hydrocarbons, strong acids/alkalis and ozone; avoid prolonged contact with these media. - Swelling, loss of mechanical properties or accelerated aging may occur with incompatible fluids or high concentrations of solvents, especially at temperature extremes. - Verify compatibility for specific media, concentrations and dynamic conditions (pressure, movement); perform supplier compatibility data review and, if needed, soak/swelling tests at â10Â°C to +80Â°C.

How should Joint gasket GOST, NBR for symmetrical joints per GOST 28352-89 and 2217-66 be stored to preserve performance at -10Â°C to +80Â°C?

Joint gasket GOST, NBR Format should be stored to preserve performance at -10Â°C to +80Â°C as follows: - Storage environment: store indoors in a clean, dry, well-ventilated area protected from direct sunlight, UV sources, ozone (e.g., electric motors), open flames and significant temperature fluctuations. Ambient storage temperature range: ideally +5Â°C to +25Â°C; absolute allowable short-term range must stay within -10Â°C to +40Â°C to avoid accelerated ageing. Avoid storage above +80Â°C. - Humidity and condensation: maintain relative humidity below 65% and prevent condensation. Keep items off cold floors and away from damp walls; use pallets or shelving. - Packaging and orientation: keep gaskets in original, airtight packaging until use. If repackaging, use opaque, moisture-resistant packaging (polyethylene or metallized film) with desiccant. Store flat or in original coils without sharp bends, compressions or stacking that causes deformation. Do not hang heavy loads on gaskets. - Chemical and mechanical protection: separate from oils, solvents, fuels, acids, alkalis, plasticizers and volatile chemicals that can migrate into NBR. Avoid contact with metal salts, paints and greases. Protect from mechanical damage, cuts and abrasion. - Light and ozone protection: shield from fluorescent lights and corona discharge sources; avoid proximity to ozone-generating equipment. - Rotation and inspection: apply first-in, first-out (FIFO). Inspect periodically for surface tackiness, cracking, hardening, swelling, discoloration or permanent deformation. Reject and document any items showing deterioration. - Shelf life guidance: use within 3â5 years from manufacture when stored under recommended conditions; reduce usable life if exposed to higher temperatures, sunlight or contaminants. - Handling precautions before installation: condition gaskets to installation temperature range, avoid stretching beyond design limits, and check dimensions and physical integrity prior to fitment. Following these practices will help preserve the sealing properties and service life of Joint gasket GOST, NBR Format within the specified operating temperature range.
