Concealed oil way. The cavity of ram is ellipse. Hydraulic pressure: 1200~1500psi(8.4~10.5mpa) Hydraulic connection: npt1 Working temperature: -29 Media: oil gas & drilling fluid containing h2s Ram size and type : series size pipe ram, reducing ram and cutter ram.
The 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 efficiently 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.
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 th 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 sa the common ram.but need to replace tha hanger pf the main piston to hunger. otherwise it will not be used. -
