This RS Clare range was designed to further expand on the sealing performance that had been achieved with Valve Lubricant 601. Gate valves leak when there is damage across the sealing surfaces of the gate or seats, in the form of galling, scoring or cutting. The severity of the damage is key to how well a certain lubricant or sealant will perform, in terms of filling in the damaged area and assisting the valve to hold pressure across the seal system.
Valve Sealant 701 is able to seal gate valves which have moderate to severe damage on the gate and seats. This performance has been proven both in the pressure test workshop, by using purposely cut seats in the test valve, and latterly across the industry in actual field deployment. Many successes have been documented, after all other attempts to seal the valve with other sealant products have failed.
The significant performance success of 701 has led to a major IOC implementing a formal technical procedure for establishing well barrier integrity using 701. In addition, a major valve OEM has classed the product as an important valve sealing tool to have available for all wellhead workover jobs, where a leaking valve may be encountered.
701 is guaranteed to reduce the operational costs associated with leaking valves. When planning your intervention job, where you will require integral well barriers, ensure you have Valve Sealant 701 and a suitable RS Clare spec pump system.
The sealing performance of 701 is documented in the Pressure Test Workshop Report and the Case Study Field reports. For more information please fill in the enquiry form and one of our technical team will be in touch.
