Usage
HWDP is the transition zone between drill collar and drill pipe. It can not only reduce stress-formation in the connection of drill collar and drill pipe, but also reduce the wear on OD. The wall thickness of heavy weight drill pipe is between drill pipe and drill collar, its structure is similar with drill pipe. It is made from premium alloyed steel. Its both tool joints and middle upset are welded hardbands.

Applications
The sucker rod is widely used in the oil extraction industries. The different grade sucker rod can be applied in different applications.
Grade C sucker rod
Moderate strength, has a certain degree of resistance to the sulfide stress cracking, it is suitable for sour environments.
Grade D sucker rod
The grade D sucker rod is manufactured from high quality heat treated steel alloy, which has high tensile and yield strength, it is can be used in the non-corroding or mildly corroding environments.
Grade K sucker rod
The grade K sucker rod has a good corrosion resistance in H2S, CO2, and NaCl media, it is widely used in corrosion environments.
Grade H sucker rod
This is a type of sucker rod with extra high tensile strength it is ideal for deep and large wells.
