Ram type BOPs are field proven products that are designed for a variety of operations from workovers 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. 

Mud pump spare parts as one of the expendables what need to be replaced frequently in drilling service, the quick matching, high quality and competitive price will be ensured from Lake Petro. Our products are 100% interchangeable with the original equipment manufacturer in every way.

Accumulator unit for BOP stacks is a very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. It consists of remote control system, driller’s panel, air cable (except electrical type), pipe rack (electrical warming system available for cold area), high pressure manifold, protection room, etc.
