For beam-pumping well applications, we manufacture high-quality, highly dependable standard and custom-designed blowout preventers (BOPs) from materials ranging from ductile iron to corrosion-resistant alloys. Pressure-tested at twice their respective work ratings, all Double E blowout preventers can be manually or hydraulically operated. BOPs for pollution control feature automatic ram closure. BOPs for sour service can be traceable, serialized, and certified to NACE requirements. Dozens of proven and dependable designs are available off-the-shelf; but as with all Double E products, special orders are always welcome.
