Elfab’s pressure activation devices (PAD) designed for activation within several applications

Elfab Pressure Activation Devices provide high dependency in difficult downhole conditions with industry leading tolerances and excellent corrosion resistance. The PAD is suitable for a wide range of burst pressures and capable of withstanding high back pressure ratios.

All PAD discs offer a high integrity solution with superior leak-tightness critical for the applications in which these products are used.

Each rupture disc is manufactured using our in-house electron beam welding capability, benefiting from utmost reliability and superior performance.

Provides high dependency in difficult conditions

Within certain applications, reliance on pressure activation is crucial. Elfab’s PAD discs offer industry leading tolerances and excellent corrosion resistance, available in corrosion resistant materials such as Stainless Steel and Inconel as standard with other materials available on request.

All PAD devices are PED complaint, accredited to a number of industry standards and accreditations and can be manufactured to ISO 4126 or ASME VIII dependent on customers’ requirements.

Typical applications

There are several variations to the Elfab PAD range dependent on burst pressure and application requirements, common applications include:

– Drill Stem Testing
– Motorhead assembly
– Circulating sub
– Hydraulic disconnect
– Tubing tester valve
– Downhole completion
– Casing protection
– Perforating
– Cementing

Unique PAD benefits

– Corrosion resistant
– High accuracy and reliability
– Tight tolerance
– High operating ratio
– Eliminates inaccurate drop bar / shear pin devices
