E/F type pneumatic chuck is mainly used for clamping drill pipe and tubing in oil and gas workover operations. The products shall be designed and manufactured according to API Spec 7K Drilling and Well Servicing Equipment. All chucks can be operated manually, pneumatically or hydraulically, which effectively reduces the labor intensity of workers and improves work efficiency. The pneumatic chuck has reasonable structure, convenient operation, safety and reliability, and is an ideal tool for workover operations.
QP250/350 pneumatic chuck is mainly used for clamping drill pipe, tubing, casing and other pipe strings in oil and gas drilling and workover operations. The products shall be designed and manufactured according to API Spec 7K Drilling and Well Servicing Equipment. Effectively reduce the labor intensity of workers, improve work efficiency. The pneumatic chuck has reasonable structure, convenient operation, safety and reliability, and is an ideal clamping tool for drilling and workover operations. In the drill pipe tripping operation, in addition to the normal tripping and clamping functions, the function of automatic air jet mud scraping is also added. The pneumatic chuck has a self-locking function. When the slip body clamps the pipe string, it has the self-locking function of preventing the slip body from being accidentally opened; when the slip body is opened, it has the function of preventing the slip body from being accidentally cut off.
The hydraulic chuck is based on the actual needs of the user site, and the design is improved on the basis of the pneumatic chuck. The action of the slip body is driven by a hydraulic cylinder to realize opening and closing. At the same time, the position sensing function can be added according to the user's demand. It can feed back the action state of slips to the driller room.
Rotary table core and lining are made of high-quality alloy steel castings, and the size conforms to API Spec 7K. The core has two structural forms: integral and split, and two main types: distribution drive and four-way drive. API standard drill pipe slips, drill collar slips, casing slips or roller core can be placed in the lining.
Casing core patting of CU, CUL, CB and other types can be used for clamping pipe diameters of 23/8in to 30in. Among them, CU and CUL are integral core filling; CB is split core filling, and the size is in accordance with API Spec 7K standard.
WQ375 series pneumatic slips are installed in the 375 rotary table. The balance beam is connected to the four-page slip body through the connecting rod, and the cylinder is fixedly connected to the balance beam. When tripping the drill pipe, the slip body descends along the conical surface of the main body, pushing the drill pipe to close to the center and clamping the drill pipe tightly. When lifting the drill pipe, the slip body shall loosen the drill pipe upward along the conical surface of the main body to make the drill pipe and coupling pass through the space.
WQ16 pneumatic slips are installed in the turntable instead of the inner lining. By manipulating the control handle, the cylinder is controlled to drive the balance beam up and down to push the slips up and down.
The power slip is designed and manufactured according to the requirements of API Spec 7k. It is a device for lifting drill pipes, casing and other pipe strings in oil and natural gas drilling operations. Power slips can be divided into hydraulic slips, pneumatic slips, etc.
WQ type external pneumatic slip is designed and manufactured by our company according to API Spec 7K specification. It is suitable for tripping operation in drilling and workover operation in oil field. It can hold drill pipe, drill collar, casing and other pipe strings. It is mainly composed of slip lifting device, slip and pneumatic control assembly.
