Permanent municipal and industrial pipeline engineering requires valve equipment with ultra‑long service life to reduce secondary replacement and reconstruction costs. Ouwei fully welded ball valve adopts integral forging and full penetration seamless welding technology, with uniform and firm welding seams, no structural weak points. The overall sealed structure effectively avoids rusting, aging and damage of internal components.Compared with traditional assembled valves with multiple connecting parts, Ouwei valves have fewer vulnerable parts and stronger overall stability. After professional stress relief treatment, the valve body can resist natural settlement, mechanical vibration and long‑term load pressure of pipelines. It can stably operate for more than 30 years in buried and indoor pipeline environments, becoming the preferred permanent matching equipment for urban energy and industrial pipeline systems. #Ouwei #LongLifeValve #PermanentPipeline #FullyWeldedBallValve #IndustrialEngineering
