Clamps provide a reliable means to join API and other hub connections. Any of the equipment in the following list may have clamp hub connections:
Wellhead Equipment
Casing Heads
Casing Spools
Tubing Heads
Valves
Chokes
Crosses
Tees
Flowlines
Drilling Equipment
Spools
Blowout Preventers
Choke and Kill Manifolds
Manifold Systems
Mud Systems (Pump to Standpipe)
Oil and Gas Production
High Pressure Supply Lines
Clamps allow faster and easier make up. Where limited space requires, clamp orientation adjustment allows easy access to nuts and bolts. Clamp connections have 360° infinite adjustability.
Manufactured clamps from material which meets or exceeds the requirements of API Spec 16A for material qualification, processing, chemical composition and mechanical properties.
The Hub adapter with one end connects with Clamp by bolts and nuts, the other end can be flange end as per API6A and 5B, can be Threaded, or can be weld neck union as per different applications.
