Dual-connection fracturing fluid delivery technology
Speed up multiwell pad rig-up with a flexible, erosion-resistant conduit that couples the frac manifold to the frac tree.
Replacing inherently weak conventional hammer unions as the primary connection for frac iron and high-pressure hoses with the 3-in clamp quick-connect system (CCS30) brings numerous benefits:
The clamp quick-connect system is a 3-in connector for 2-, 2.7-, and 3-in small-bore frac hoses that connect the pump trucks to the missile. The hub adapter option enables connection to any pump union type.
The CCS30 is a fast connection or union that was adapted to onshore frac operations from an innovative subsea operations application. The CCS30 uses a single-bolt setup that enables setting or unsetting the clamp in a few seconds using a standard torque wrench. Designed to withstand vibration and the loads originated by the dynamics of frac operations, the highly reliable system provides a proprietary wear-resistant metal-to-metal seal and includes a secondary locking component that eliminates the risk of possible backing up of the lead screw.
Compared with the hammer union, the CCS30 can correct for some misalignment. For hammer union connections makeup, the two parts to be connected must be perfectly aligned to engage the male-female threads. The quick-connect clamp allows up to 15° of misalignment between the two components to be connected because the CCS30 grabs and pulls the hubs into place.
The CCS30 includes a blind cap for use as a secondary barrier when the frac hoses are disconnected from the clamp. This prevents fluid release to the atmosphere in the event that upstream isolation valves are leaking.
