API 16A Ram BOP

Available with a wide variety of sizes and end connections.
U type ram BOPs are forging materials, which have better strength and impact toughness.
Auxiliary oil cylinder is smaller volume than traditional type.
Manual locking device can ensure that ram remains closed once hydraulic loss happened.
Ram rubber use self-contained seal, and the material can be different according to environment temperature and liquid components.
The internal part of BOP can adapt special material, which can achieve the highest levels of resistance to H2S and CO2.

Ram type BOPs are field proven products that are designed for a variety of operations from work-overs to high pressure, critical service operations for land drilling and subsea service. It consists of the BOP body, bonnet, hydraulic cylinder assembly, operating piston, ram change cylinder, ram opening/closing piston, locking screw, ram assembly, sealing parts etc. Top, bottom and outlet connection dimensions conform to Specification for Drilling through Equipment API Spec 16A.

Made up of the high-strength and high-tenacity alloy steel, the pressure-bearing parts (like BOP body, bonnet etc.) are formed through external refining and proper heat treatment, preventing the harmful chemical components and nonmetallic inclusion strictly from materials and ensuring BOP to be safe and reliable. The body ram chamber adopts the long runway to reduce stress concentration.

Both the bonnet switch and ram switch are driven by the hydraulic pressure and adopts the same one oil line. The bonnet employs the same one oil line and operation to open and close the ram. Moreover, the bonnet employs the same one oil line and operation to close and open the ram.
