The annular manifold   mainly includes 3 types: Short - radius movable manifold, long- radius movable manifold and integral   movable   manifold,   with   specification   being   1 - 1/2",   2",   3"   and   4"   and   working   pressure   being 35MPa~105MPa( 5000psi~15000psi).

The   movable   elbow   equipped   for   annular   manifold   has   such   characteristics   as flexibility,   shock   resistance,   anti - vibration and large discharge . The annular manifold is connected by wing nut and has   such characteristics as quick tightening   and   disassembly,   pressure   resistance   and   sealing,   which   is   easy   for   coincidence   and   convenient   for transportation and storage .

Application

● Applicable to connection at locations when drill platform, semi -submersible drilling vessel or drilling vessel moves relatively and the installation dimensions of the drill rig subsequently change,and to delivery of oil, gas, mud and other high pressure media (including mainly relief line,blowout control line and choke kill line).

● Applicable standard: API Spec 16CSY/T5323- 2004

● The product features resistance to high pressure, thermal insulation, anti -flaming and fire resistance as well as

inner wall with high abrasion resistance .
