Integral heavy weight drill pipes are manufactured from AISI 4142H-4145H modified drill collar material according to SY/T 5146-1997, thick-walled pipe called integral heavy weight drill pipe was developed to provide a gradual transition from the heavy weight drill pipe to the relatively light weight drill pipe. This intermediate weight pipe has a wall thickness of approximately, and it helps prevent stress concentration at the top of the drill collars.

• The workover rigs are designed and manufactured in accordance with API Spec Q1, 4F, 7K, 8C and technical standards of RP500, GB3826.1, GB3836.2, GB7258, and SY5202.


• The whole rig is compact, highly integrated, and requires a small space for installation.


• Type 8x6 heavy-duty chassis furnished with the rig carrier, complete with constant drive and self-propelled, equipped with hydraulic steering system and have a good capability of passage and cross country.


• A reasonable assembly of CAT engine and ALLISON transmission box can supply a high driving efficiency and increase safe performance.


• Band brake or disc brake is applied for the main brake and the air disc brake/water brake or FDWS is used for auxiliary brake.


• The compound box for rotary table has a function of forward-reverse speed shift gears, which can be suitable for DP'srotary operations. The anti-torque releasing device can be used to release the deformation energy of the DP safely.


• The derrick is a two-section, front open derrick can be telescoped, raised and extended hydraulically.


• The drill floor is twin-body telescopic type or with parallelogram structure, which is convenient for installation and transportation. The dimension and height of the drill floor will be designed according to the user'srequirements.
