ASTM A252

ASTM A252 is the standard specification for welded and seamless steel pipe piles. It covers the nominal wall thickness of cylinder shape steel pipe, rectangular pipe is not included. These round pipes are used for piling purposes, playing as a permanent role of load carrying and bearing the pressure. Further more, to act as a tank shell to fill with the concrete piles at sight of the project.This standard stated the values units in inch-pound (also could be translated to SI units), which provides the reference A252 pipe data to engineer or designer, for a strength base of the constructions.The ASTM A252 standard covers steel piling pipe that is used in the construction industry for foundation applications. The ASTM A252 steel piling pipe is available in three grades based on strength levels: Gr.1, Gr.2, and Gr.3.

The functions and uses of casing pipe?

Casing pipe is an indispensable equipment in oil drilling and plays an important role.Casing pipe is a steel pipe that supports the walls of oil and gas wells. Each well uses several layers of casing based on different drilling depths and geological conditions. Cement must be used to cement the casing after it is lowered into the well. Unlike oil pipes and drill pipes, it cannot be reused and is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes. According to the usage, casing can be divided into: conduit, surface casing, technical casing and oil layer casing, and their structure in the oil well.
