Carbon Steel Tubes ASTM A53 Grade A Grade B For Use In Low Pressure Environments
Product Description
ASTM A53 is the American Society for Testing and Materials (ASTM) standard specification for "Black and Hot-Dip Galvanized, Welded and Seamless Steel Pipes." It covers steel pipes manufactured using both welded (Type F, Type E) and seamless (Type S) processes. Here, we focus on the seamless steel pipe section.
Key Characteristics and Grades
Type: Type S (Seamless)
This explicitly indicates that the steel pipe is manufactured using a seamless process, without welds.
Steel Grade
Grade B: This is the most commonly used and prevalent grade. Its yield strength is 240 MPa (35 ksi), and its tensile strength is 415 MPa (60 ksi).
Grade A: Lower strength, less frequently used. Yield strength is 205 MPa (30 ksi), and tensile strength is 330 MPa (48 ksi).
Grade A25: Very special, rarely used in seamless steel pipes, primarily specified for threaded pipes.
Chemical Composition
ASTM A53 has relatively broad requirements for chemical composition and is a type of carbon steel. Its main elemental content (such as carbon, manganese, phosphorus, and sulfur) meets general engineering requirements, but is not as stringent as some specialized pressure vessel or boiler steels.
Coating
It can be supplied as uncoated black tubing or hot-dip galvanized for corrosion protection. The galvanizing mark is usually "Galvanized (Galv.)".
Main Applications
ASTM A53 Gr.B seamless tubing is a "general-purpose pipe" in many industries due to its good mechanical properties, machinability, and economy.
Low-Pressure Fluid Transport Systems:
Water, gas, oil, and steam transport pipelines. This is its core application.
Commonly used in building interiors for fire sprinkler systems, domestic water pipes, and HVAC systems.
Structural Applications:
Although not a high-strength structural steel, it is widely used in scaffolding, guardrails, fences, structural supports, and other applications where extremely high strength is not required.
Mechanical Parts:
Used in the manufacture of mechanical components such as shafts, sleeves, and rollers that do not withstand high pressure.
Bridges and Buildings:
Used as non-load-bearing or secondary load-bearing structural components.
Delibery Time:
20ft GP: 5.8m(length) x 2.13m(width) x 2.18m(high)40ft GP: 11.8m(length) x 2.13m(width) x 2.18m(high)
40ft HG: 11.8m(length) x 2.13m(width) x 2.72m(high)
