BOP Parts

BOP part name: Packing element, shear ram, pipe ram, blind ram, variable bore ram, top sealing, front sealing, bonnet, piston, shell.

The packing element for Annular BOP has special type and taper type. The packing element is combined by the main body which is made up of the independent innovation rubber based polymer alloy material and the high strength metal frame, which conforms to the USA 16A, SATM D412, D624, D2240 and D471 standard. It is suitable for the drilling work on the oil field, which shares a high cost performance comparing to the other same type packing elements.

Shear ram is composed of upper ram body, lower ram body, top seal, right seal, left seal and tool face seal.  Tool face seal is placed in front slot of the upper ram body, with right seal and left seal on the both sides. The shear ram is installed in the BOP in the same manner the common ram. but need to replace the hanger of the main piston to hunger. Otherwise it will not be used.

The Pipe Ram is use for single or double Ram Blow Out Preventer(BOP).The ram’s size is matched with the pipe’s OD. It can be closed between the pipe stem and well annular space.

The Blind Ram is use for single or double Ram Blow Out Preventer(BOP). It can be closed the well when the well without the pipe line or blowout.

The Variable bore ram as a improved type, is capable of sealing around drill pipes with a range of sizes and have advantages such as low cost and convenience, expatiate on the sealing well mechanism. The operation of the variable bore ram is simulated with the finite element model, the distribution of the stress is analyzed, which provides the toudation for optimizing the design of variable bore ram-type blowout preventer.

Other BOP parts that we supply all come from original/OEM manufacturers, they are 100% interchangeable.
