Hilong Landing String Drill Pipe

Product Introduction 

Hilong landing string drill pipe is typically used to land heavy casing strings in a deep-water environment. Designed at the aspects of the drill pipe structure, material strength, etc., so that the landing string drill pipe has sufficient tensile load capacity to meet the tensile requirements of large-size heavy-duty landing. The design of the Hilong landing string drill pipe ensures it has reduced weight, increased tool joint and pipe body tensile strength, and increased elevator lifting capacity, thereby improving the casing lowering capacity.

 Product Structure and Advantage

·Thick-walled, high steel grade pipe body, to increase tensile and hoisting capacity.
·Increased drill pipe tool joint outer diameter/double outer diameter structure, to increase load capacity of the elevator.
·Slip-protected section, to increase slip crush damage capacity.
·According to customers' special requirements to provide the most appropriate landing string design.
