Natural Gas Industries ASTM A252 GR3 ERW Steel Pipe

Natural Gas Industries ASTM A252 GR3 ERW Steel Pipe

ERW steel pipe is one of the main pipe structural material in construction and liquid transfer steel material. It is properly used in bridge building, underground transfer assemble structure ,agriculture, chemical liquid transfer, oil and gas transfer and so on, It will be manufactured by electricity resistance welding. The outside surface can be treated by galvanizing, painting, PE coating, PP coating, HDPE coating and so on, The main advantage is welding beam can be very smooth. It is very good to do the transfer and liquid job. Standard can be API, ASTM, etc.

Specification

American Standard ASTM A252 is pipe piling material standard that has been widely used in constructions and structural buildings. A252 specification includes three grades (1, 2, and 3), Grade 3 pipe piling material is the most used option.

ASTM A252 definitions

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.

Reference standards for making ASTM A252 pipe

• ASTM A370 inspection methods and definitions for mechanical test of steel products.
• ASTM A751: Chemical analyze test methods.
• ASTM A941: Terminology for carbon, alloy and stainless steel.
• E29 practice for to use significant digits in test result to decide the conformance with specification.

ASTM A252 pile pipe material and manufacturing types

Considering on the manufacturing types, ASTM A252 pipe piles could be made by seamless or welded processes.

Welded pipe pile

Welded pipe pile including ERW (electric resistance welded), flash welded, fusion welded or sub-merged welded SSAW or LSAW. Longitudinal or helical spiral welded.

Raw material making process

Raw material iron and steel could be made through the process of Open-hearth, Basic-oxygen, Electric-furnace.
