Back pressure pads can play an important role in effective, efficient and safe pipeline operations. Using nitrogen, back pressure pads address two critical elements of flooding a pipeline with product: safety & product separation.
Hydrotests can play an essential role in pipeline commissioning. Our experienced project managers, operators and engineers can determine material strength, find gross leaks, and provide hydrotest solutions for pipelines, tanks, vessels, and facility piping.
When a valve cannot be isolated and work is required downstream, or when searching for leaks during a hydrotest, nitrogen assisted freezing and viscous fluid sealing can be effective. Blackstone Pipeline’s nitrogen assisted freezing process uses closed-chamber freeze isolation to ensure safety, while temporarily quarantining the required section of pipe.
Drying is a critical step for maintaining the integrity and performance of your pipeline. Pipeline drying can be achieved using a variety of methods including nitrogen, air, methanol, and swabs.
There are many different reasons to leak test a pipeline and a variety of methods that can be used. Many leak testing methods rely on changing the system pressure, and/or injecting and detecting a chemical. Our expertise in pressure pumping and chemical processes enables us to perform expert leak detection services using a wide range of methods.
The most effective pipeline cleaning and pigging comes from a thorough investigation and understanding of line contents and deposits. Our system-specific programs use selective chemistries for black powder removal and abatement, wax removal, asphaltene removal, and engineered viscous fluid programs for inorganic deposit removal.
