Heavy-Duty Gray Cast Iron End Covers

This gray cast iron end cover is a core sealing accessory for fire protection and industrial pipeline systems. It is made of high-strength gray cast iron and formed by precise sand casting process. The internal structure is dense and has excellent mechanical strength. It can withstand pipeline pressure of more than 1.6MPa and is suitable for the end sealing requirements of common pipe diameters such as DN50 to DN100. The surface of the product is treated with industrial-grade red anti-rust paint by spraying. The coating has strong adhesion and can effectively resist corrosive environments such as outdoor humidity and acid and alkali mists. It is not easy to rust or peel off after long-term use. The symmetrically distributed double lug design reserves space for wrench operation. During installation, it can be quickly tightened and force applied. Combined with the precise embedding of the center positioning column, it can achieve a tight seal at the pipe end, preventing medium leakage o…
