High Pressure Wellhead H2 Choke Valve
Interchangeability of parts to construct a positive, adjustable, or combination choke.
Bonnet nut has rugged integrally forged lugs for hammering nut loose.
Built-in safety feature that releases residual pressure in the choke body before the nut is fully removed. The inside of the choke body is vented to atmosphere after the bonnet nut is partially removed.
Interchangeability of component parts for a particular pressure range. For example, the same blanking plugs and bonnet assemblies are used in nominal 2000 through 10,000 PSI WP

API 16D Certified BOP Closing Unit
A BOP accumulator unit (also known as a BOP closing unit) is one of the most critical components of blowout preventers. Accumulators are placed in hydraulic systems for the purpose of storing energy to be released and transferred throughout the system when it is needed to accomplish specific operations. BOP accumulator units also provide hydraulic support when pressure fluctuations occur. These fluctuations happen often in positive displacement pumps due to their operational functions of trapping and displacing fluid.
-
API 16 RCD Certified Rotary Preventer
The rotary blowout preventer is installed on top of the annular BOP. During underbalanced drilling operations and other pressure drilling operations, it serves the purpose of diverting flow by sealing the rotating drill string. When used in conjunction with drilling BOP, drill string check valves, oil-gas separators, and snubbing units, it allows for safe pressurized drilling and snubbing operations. It plays a vital role in special operations such as liberating low-pressure oil and gas layers, leak-proof drilling, air drilling, and snubbing well repairs.

Shaffer Type BOP part shear ram assembly
· In accordance with API Spec.16A
· All the parts are original or interchangeable
· Reasonable structure, easy operation, long life of core
· Adapt to a wide range, capable of sealing pipe string with nominal path shapes, better performance by combining with ram blowout preventer in the use.
A shear ram can cut pipe in the well, blindly close the wellhead, and also be used as a blind ram when there is no pipe in the well. The installation of the shear ram is the same as the original ram.

-
BOP part U type shear ram assembly
The large frontal area on the blade face seal reduces pressure on the rubber and increases service life.
Type U SBRs can cut pipe numerous times without damage to the cutting edge.
The single-piece body incorporates an integrated cutting edge.
H2S SBRs are available for critical service applications and include a blade material of hardened high alloy suitable for H2S service.
The type U shearing blind ram has a single-piece body with an integrated cutting edge.
