It’s made of high quality alloy steel by forging, which features high strength, small volume, low weight, convenient disassembly and transportation. Its external surface has Nickel & Phosphor plating, which has good anti-corrosive property.
There are two connection methods between roof cover and body of annular preventer, bolt joint and block connection. Round annular preventer consists of five main parts: roof cover, body, piston, ball core and dustproof ring. Taper annular preventer consists of seen main parts: roof cover, anti-wear plate, body, piston, taper core, dustproof ring and supporting column. The sealing of round annular preventer adopts lip-shape sealing ring, it can reduce the abrasion of sealing farthest. The sealing is reliable and the glue core is not easy to turn over. It also has filler effect. The well pressure is helpful to sealing.
