Engineering Pressure-Resistant Gray Cast Iron End Covers

This gray cast iron end cover for engineering is one of the essential accessories for sealing the ends of pipeline systems. Made of high-density gray cast iron, it undergoes strict casting and heat treatment processes to ensure that the accessories have no defects such as sand holes and gas holes, with stable mechanical properties. It can be adapted to pipeline systems with a pressure rating of ≤2.5MPa. The red anti-rust paint layer on the surface has been verified by salt spray tests to have an anti-rust effect of over three years, which can meet the corrosion challenges of most industrial environments. The double lug design of the product takes into account both operational convenience and structural strength. During installation, it can be quickly tightened with a common wrench. The central positioning structure has a high matching degree with the pipe end, and the sealing surface adheres tightly, effectively preventing the leakage of liquids and gases. It is widely applied in pipe…
