BOP Stacks

Well control equipment is mainly implimented in the operation of drilling, work-over and well testing etc. to control wellhead pressure, effectively prevent the occurrence of a blowout accident and secure drilling operation.

Since the first successful trial production of F23-35 BOP Stacks in China in 1974, we have continuously developed several BOP Stacks with various bore size from 7.1/16" - 21.1/4" and working pressure ranking from 14MPa to 105MPa. Relying on our experience in design and manufacture for 10 years, we independently developed F105 series BOP stacks with rated working pressure of 15000psi, which can serve for deep wells, ultra deep wells and high pressure oil and gas wells. F105 series BOP stacks are widely used in domestic oilfields in China and have already been exported to overseas markets such as South America, North America, Russia, Mid Asia, Middle East, South East Asia, Africa etc in recent years.

Production Testing:

• Chemical analysis
• Mechanical properties
• Nondestructive testing
• Metering room
• Metallographic test analysis
• Oil way strength test of the oil cylinder and hydraulic cylinder of BOP
• Hydrostatic test of the performance and strength of BOP
• Air tight test
• BOP control pump and valve test room
• Acoustic emission detection equipment
• Resistance strain and stress test
