Blowout Preventers (BOPs) are safety devices used to \"prevent\" the uncontrolled flow of liquids and gases during well drilling operations. Blowout preventers are large, high-pressure valves that are capable of being remotely controlled. When the driller closes the valve, a pressure-tight seal is formed at the top of the well, preventing the fluids from escaping. The WEATHEROCK GROUP is also one of the leading Blowout Preventer (BOP) Manufacturers. WeatherockGroup worldwide is one of the world\'s top manufacturers & Supplier of top-quality Double Submerged arc welded (DSAW) Pipe and Longitudinal Welded Pipe. Our high-performance products include Induction Bend Pipe Manufacturers sensor . to help detecting internal flaws in it. .
