API 16A oilfield blowout preventer equipment bop ram
Product DescriptionThe blowout preventer(BOP) is an essential pressure control device during driling and operations, as it serves to prevent the uncontrolled leakage of oil/gas from the wells. Over the past 40 years, Shengji has been maintaining and repairing BOPs at the Shengli Oilfield.In 2006, Shengji got its API 16A certificate (certificate No. API 16A-0172) for fabricating BOPs and related accessories. Since then, Shengji has developed three series of BOPs: drilling BOP, workover BOP and oil producing BOP. Shengji can also produce annular BOPs, single ram BOPs and double ram BOPs. The BOP rams are manifold, including: blind ram, pipe ram, shear ram and variable diameter ram. Due to its stable performance and long service life, Shengji BOP wins high praise from our customers.
The Shengli hydraulic ram BOP is mainly used in workover and drilling operations with varied technical requirements. With a BOP body,side outlet, ram body, and other pressure bearing parts crafted from defect-free forged metal, and an oval-shaped inner chamber to reduce stress concentration and improve its sealing performance, this BOP can efficientlyl prevent an oil well blowout.
The double ram BOP can be equipped with different types of rams, such as pipe ram, blind ram, shear ram or variable diameter ram, to meet different applications. The ram seal is a float type, which will decrease the resisitance and abrasion of the rubber core.The service life is greatly prolonged. Its anti-H2S performance conforms to NACE MR 0175 standard.
Key Feature
1.Double ram BOP seals annular space between tubing and casing or wellbore.
2.Double ram BOP suspends and stabilizes string.
3.Double ram BOP with side outlets could be used for choke and blowout.
4.Double ram BOP can be used in operation under pressure.
