ППШР-2ФТ-152х21
Ram&vane preventers with separate arrangement of rams and vane
with manual drive and remote control capability
Small-sized spot preventers with manual drive are used during routine and capital repairs of wells, all types of geophysical work, including perforation and drilling and blasting operations, as well as when cutting side boreholes. They have a solid cast alloy steel body without a single connection, including a welded one, which eliminates the need for flaw detection during technical inspections.
