The swivel includes two main categories, which are common swivel and double duty swivel. Double duty swivel is a common swivel combined with a spinner. Common swivel consists of swivel bail, shell, support, gooseneck, central pipe, master bearing, joint and other parts. The lower end is connected with kelly stem by REG thread. The swivel bail is hung on the hook. Gooseneck and rotary hose can be connected by REG thread connection or union connection. Washpipe packing set assembly adopts cassette structure, so it can be quickly replaced without disassembling rotary hose and gooseneck. 3LP and 4LP internal or external thread hose connection thread are available for you. We can also manufacture low temperature resistant swivel according to customer's requirements. Our swivel meets API SPEC 8CPSL1 standards. It has been awarded the API certification issued by the American Petroleum Institute and is allowed to use API monogram.

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.

The basic principle of the hydrocyclone is to separate the two-phase or multi-phase mixture of liquid-liquid, liquid-solid, liquid-gas and so on with a certain density difference under the action of centrifugal force. The mixed liquid is tangentially flowed into the cyclone with a certain pressure, and a high-speed rotating flow field is generated in the cylindrical cavity. The high density components in the mixture under the action of the swirling flow at the same time along the axial downward movement along the radial outward movement in the reach of the cone down along the wall along the wall, and from the bottom outlet, thus forming The small vortex component moves toward the central axis and forms an upwardly moving internal vortex in the center of the axis, and then is discharged from the overflow port, thus achieving the purpose of two-phase separation. Polyurethane characteristics: 1. The hardness range is wide, and the elongation and elasticity of the rubber are still under high hardness. The hardness range of polyurethane board is Shao A10-D80. 2. High strength. In rubber hardness under their tensile strength, tear strength and bearing capacity rubber is much higher than general. Under the high hardness the impact strength and flexural strength and is much higher than that of plastic. 3. Wear resistance. The wear resistance is very good, about 3-5 times of the rubber. 4. Oil resistance. Polyurethane board is a strong polar polymer, and the affinity of non polar mineral oil, in fuel oil and mechanical oil is almost no corrosion. 5. Good resistance to oxygen and ozone. 6. Excellent absorption performance, can be used to reduce the vibration, buffer effect. In the mold manufacturing industry, alternative rubber and spring. 7. It has good low temperature performance. 8. Radiation resistance, high energy - ray properties of the polyurethane, the use of the 10-10 radiation dose is still satisfactory. 9. Have good mechanical processing performance. (car, milling, grinding, drilling can be) Application: widely used in machinery, transportation, oil, mining, construction, textile, sports and other fields. The company to undertake a variety of specifications of the size of polyurethane products custom processing.
Drilling Jar Type BZ is full mechanical type drilling jar and releasing stuck tool. The Drilling Jar integrates the upward jarring with the downward jarring so that it can release from the tight pull or the sticking etc. during drilling. The load(jarring force)scope of the upward jarring and the downward jarring is so wide that it can be adjusted in the maintenance station or in the well site according to the requirement. The special flexible joint can reduce the flexural stress of the drilling jar body efficiently. So it is the first selected drilling jar for vertical well, deep sell, directional well and complicated well operations.

Working of BOP pare parts: When wells must be sealed in case of kicks high pressure (10.5Mpa) oil from control systems enters into close-cavity under piston from housing oil outlet, to promote plastic core moving upward along ball surface, so that bearing tendons move closer to each other to moce the rubber between them to the center of wellhead so as to seal drilling tools or fully seal wellhead. In opening , hydraulic pressure oul enters into open-cavity above piston from housing oul inlet, to push piston moving downwards , so that plastic will reset with its own elasticity, wellhead will be open.
