Hydraulic Slips

Hydraulic Slips are one of the excellent wellhead automation equipment during the drilling operation, hydraulic slips have the function of clamping and holding drill strings, such as drill pipes, casings and drill collars, etc, and also have the function of mud scraping. The full range of hydraulic slips are suitable for the rotary table of ZP275, ZP375, ZP495/ZP605. The maximum bearing capacity can reach 11,250kN, realizing the characteristics of convenient installation, reliable performance, simple operation, convenient maintenance and high ability of automation, etc.

Performance Characteristics ：

• Centering function -- Enables slips operation even with deviated wellhead;	• Top bearing capacity -- Supports emergency dual elevator operation;
• Anti-torque function -- Applicable for casing running operation;	• Self-lubrication system -- Prevents tool joint seizure by slips;
• Automatic mud scraping and direct push cylinder -- Reduces drill string slippage risks;	• Full-cover dies -- Eliminates drill pipe damage and simplifies dies replacement;
• Quick release design -- Enables safe, labor-saving and efficient insert carriers replacement;	• Data acquisition module -- Facilitates system interlocking and integrated control.
