ASTM A252 Standard Pipe Piles Ssaw Steel Pipe Gr.2 Gr.3 Steel Grade Project
The working environment of Marine pile driving spiral steel pipe in wharf is sea water, atmosphere and soil, etc., and the corrosion of spiral steel pipe pile is caused by water and oxygen.Water and oxygen react with steel tubes to form rust.In addition, the oxygen supply is less than other parts in the attachment parts of the Marine spiral steel pipe pile, so the part with less oxygen supply will become the anode, and the part with more oxygen supply will become the cathode. In this way, a "battery" will be formed, and "pore corrosion" will be formed in the anode part of the spiral steel pipe pile.The corrosion rate of wharf Marine spiral steel pipe pile is determined by the amount of oxygen on the surface of spiral steel pipe that reaches and diffused in unit time.The main factors that promote the increase of oxygen are the concentration of dissolved oxygen in water, the flow rate, the degree of mixing and temperature.The rust formed on the surface of spiral steel pipe pile due to corrosion becomes a barrier of oxygen diffusion to some extent and has the function of inhibiting oxygen diffusion.
This specification covers nominal (average) wall steel pipe piles of cylindrical shape and applies to pipe piles in which the steel cylinder acts as a permanent load-carrying member, or as a shell to form cast-in-place concrete piles. Pipe piles are produced as both welded and seamless products.The processed spiral steel pipe has greater flexibility in the size and specification range of diameter and wall thickness, especially in the production of high-steel grade thick wall pipe, especially in small and medium-sized thick wall pipe has incomparable advantages, which can meet the user's more requirements in the specification of spiral steel pipe.
