• Standard designation (A53/A53M)
• Type (F, E, or S) and Grade (A or B)
• Size (NPS or DN) and schedule/thickness
• Length (random or specific)
• End finish (plain, threaded, bevelled, etc.)
• Coating (if required, e.g., galvanized)
• Additional testing (e.g., hydrostatic, nondestructive examination)

• Grade A: Minimum tensile strength 330 MPa (48 ksi), yield strength 205 MPa (30 ksi).
• Grade B: Minimum tensile strength 415 MPa (60 ksi), yield strength 240 MPa (35 ksi).
• Carbon content: ≤0.25% (Grade B), ≤0.30% (Grade A).

• Tensile and yield strength: As per grade requirements.
• Bend test: Required for Type F and E pipes < NPS 4.
• Flattening test: For seamless and ERW pipes.
• Hydrostatic test: Mandatory for all pipes unless replaced by nondestructive testing (NDT).

• Hydrostatic testing: Minimum test pressure = 2.4 MPa (350 psi) for ≤ NPS 3 or higher as specified.
• Nondestructive testing (NDT): Permitted as an alternative to hydrostatic testing for Types E and S.
• Visual inspection: No defects affecting performance.
• Certification: Mill test reports (MTRs) must be provided upon request.

Coating (Optional): Galvanized pipes must comply with ASTM A53 coating weight and adhesion requirements.

Marking Requirements: Pipes must be marked with manufacturer’s name, ASTM A53/A53M standard, type (F, E, S), grade (A/B), size, heat number, and coating designation.

• Dimensional standards: Pipes conform to ASME B36.10M.
• Threading: Must comply with ASME B1.20.1.
• Usage: Widely used in construction, oil & gas, and low-pressure systems.
• Critial Applications: Stricter standards (e.g., ASTM A106) may be preferred for high-temperature service.
