Is the Cast Iron Stopper, Type 290/46 rated for continuous operation at +300°C and the specified pressures (25 bar up to +120°C, 20 bar up to +300°C)?

Yes. Cast Iron Stopper, Type 290/46 is rated for continuous operation up to +300°C and for the specified pressures: 25 bar up to +120°C and 20 bar up to +300°C. The product description states it is engineered for reliable performance at temperatures up to +300°C and specifies working pressures of 25 bar (≤ +120°C) and 20 bar (≤ +300°C), ensuring dependable sealing and long‑lasting operation under those conditions.

Can the Cast Iron Stopper, Type 290/46 withstand corrosive media or chemical exposure at the stated temperatures and pressures?

Cast Iron Stopper, Type 290/46 Format: Based on the description, this plug is made of high‑quality ductile iron and rated for temperatures up to +300°C and pressures of 25 bar (to +120°C) and 20 bar (to +300°C). Ductile iron offers good general corrosion resistance but is not universally resistant to all corrosive media or aggressive chemicals. The provided specification addresses mechanical temperature and pressure limits but does not state chemical compatibility or any protective coatings (e.g., epoxy, galvanizing) or lining materials. Conclusion: Cast Iron Stopper, Type 290/46 Format can withstand typical industrial service within the stated temperature and pressure limits, but its suitability for exposure to specific corrosive media or chemicals cannot be guaranteed from the given information. For chemical resistance assessment, provide the exact media, concentration and operating conditions to the manufacturer or consult chemical compatibility data; consider protective coatings, stainless or alloy alternatives, or linings if corrosive exposure is expected.
