Double Block and Bleed plugs are ideal in isolating certain areas of pipe for fabrication or isolated testing. Buckhorn offers this service as a means to effectively isolate areas or pipe and monitor and/or place a nitrogen blanket isolation potentially explosive vapors during hot work. The DBB allows water to be introduced between seals and perform a high pressure hydrostatic test on the single well without testing the entire line.
Isolation Test Plugs are a safe and convenient way to perform pressure tests on open ended pipe. This developing safe technology is a cost efficient alternative to welding end caps. Buckhorn can provide trained personnel and equipment to safely execute this testing strategy for it’s customers.
