Cameron SBR Shear Ram Assembly 5000psi BOP Ram Assembly For High Pressure Applications

BOP rams are core functional components of wellhead blowout preventers in oil and gas drilling and production operations. Their primary function is to achieve rapid wellbore sealing, pressure control, and working condition switching through radial closing and opening of the rams, serving as critical equipment to ensure wellhead safety and prevent blowout accidents.

Functionally, through coordinated actions with the BOP cylinder block and piston rod, the rams can precisely fit the outer walls of drill pipes, casing pipes, and other tubular products (or fully seal the wellbore), forming a reliable sealing surface. This effectively blocks the overflow channels of high-pressure oil, gas, and mud from the well while withstanding extreme wellhead pressures, providing a safe operating environment for drilling, workover, cementing, and other operations. Their performance directly determines the sealing reliability, pressure-bearing capacity, and operational response efficiency of the BOP, acting as a core barrier to safeguard the safety of oil and gas well construction.

In terms of applications, these rams are widely compatible with various onshore and offshore oil and gas well sites, suitable for the entire operational cycle including drilling, completion, workover, and well testing. They can handle multiple working conditions such as normal operations, abnormal pressure, and emergency well shutdowns, serving as key components to realize wellhead pressure control, prevent uncontrolled blowouts, and protect personnel, equipment, and the ecological environment.

Based on structural differences of compatible BOP models, the core products are divided into three series:

1. HF-type Forged Rams: Manufactured from high-quality forged materials, they feature high structural strength and excellent sealing stability. Tailor-made for the RS Shaffer series BOPs, they offer precise compatibility and meet the high-pressure sealing requirements of this series under various complex working conditions.
2. U-type Rams: With a unique structural design, they possess superior fitting sealing performance and working condition adaptability. Precisely compatible with Cameroon U-type BOPs and RS FC-type BOPs, they achieve perfect synergy with the equipment to ensure pressure control and sealing reliability during operations.
3. Holder Rams: Produced from specialized high-quality materials, integrating clamping and sealing functions, they deliver strong clamping stability and rapid sealing response. Custom-developed for Shaffer LWS-type BOPs, they accurately match the structural specifications of this model. During operations, they not only reliably clamp tubular products to prevent displacement but also achieve high-pressure sealing, meeting the safety control needs of Shaffer LWS-type BOPs under various drilling conditions.

The entire series of rams undergo rigorous strength testing and sealing performance verification, adapting to oil and gas well operations of different pressure ratings and wellbore specifications, and providing stable, durable core support for wellhead safety prevention and control.
