Ram Blowout Preventer (Ram BOP)


Ram blowout preventer (Ram BOP) is the important equipment widely used in onshore and offshore drilling. Ram 

BOP, such as single ram BOP, double ram BOP, triple ram BOP, quadplex Ram BOP, are mainly hydraulic 

operated or manual operated. All ram BOPs are strictly manufactured as per API Spec 16A

Drilling Diverter


We supply high quality drilling diverters which are manufactured and tested according to API/ISO standard.

Feature:

 

● Body and upper housing are connected by a claw chuck;

● Compact structure realizes high bearing capacity.

● Easy to assemble and disassemble and convenient for wellsite operation;

● Use lip seal rings in dynamic seal section to realize self-sealing, reduce abrasion of sealing parts and make sealing more reliable.

● Use high quality packing element and sealing parts. Use tapered type packing element, which is made of NBR. It has massive storage volume and excellent sealing function;

● Use observation hole to check the life span of the packing element;
