At ASEA METAL, we prioritize the integrity of our heat exchanger tubes. Eddy Current Testing (ECT) is a core part of our non-destructive testing (NDT) process, used to detect surface and sub-surface flaws without damaging the material.

Standard Compliance: Our ECT procedures strictly adhere to ASTM E426 (for Stainless/Nickel alloys) and ASME Section V, Article 8.
Detection Capability: We identify microscopic cracks, pits, and longitudinal defects that could lead to leakage under high-pressure conditions.
100% Inspection: Every single tube for heat exchanger bundles undergoes 100% ECT to ensure 100% reliability for our global clients.
Qualified Inspectors: All tests are performed and verified by certified NDT Level II/III technicians.

Inspection & Quality Control Flow

Stage	Inspection & Quality Control Activities
Raw Material	Verification of Mill Test Certificate (MTC) → Visual Inspection → Dimensional Check → PMI Test (Positive Material Identification)
In-Process	Cold Drawing/Rolling Process Control → Heat Treatment (Bright Annealing / Solution Annealing) → Straightening
Non-Destructive	Eddy Current Test (ET) → Ultrasonic Test (UT) → Hydrostatic Pressure Test (100% testing to ensure no leaks)
Destructive	Tensile Test → Flattening Test → Flaring/Expansion Test → Hardness Test → Microstructure Analysis → Corrosion Test
Final Inspection	Final Dimensional Check (OD, WT, Length) → Visual Surface Inspection → Stenciling/Marking → Packing & Shipping

Technical Comparison: ASTM A213 vs. ASTM A312

Category	ASTM A213 (Boiler/Heat Exchanger Tube)	ASTM A312 (Process Pipe)
Size Standard	Based on Actual Outside Diameter (OD) and Minimum Wall Thickness.	Based on Nominal Pipe Size (NPS) and Schedule (SCH) numbers.
Dimensional Tolerance	Very Strict. High precision required for OD and Wall Thickness to fit into tube sheets.	Standard. More generous tolerances allowed as it is used for general fluid transport.
Mandatory Testing	Flaring, Flattening, Hardness, and Hydrostatic or NDT (ET/UT) are mandatory for every tube.	Flattening, Bending, and Hydrostatic or NDT. Hardness is usually optional unless specified.
Wall Thickness Policy	Usually Minimum Wall Thickness (No negative tolerance allowed).	Usually Nominal Wall Thickness (Allows ±12.5% variation).
Heat Treatment	Mandatory solution annealing for all grades to ensure mechanical properties.	Required, but some specific conditions or "As-Welded" grades may exist in other pipe standards.

Technical Comparison: ASTM A213 vs. ASTM A269 (Comprehensive)

Comparison Point	ASTM A213 (Boiler/Heat Exchanger Tube)	ASTM A269 (General Service Tubing)
Full Title	Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.	Seamless and Welded Austenitic Stainless Steel Tubing for General Service.
Manufacturing	Seamless only. Welded types are strictly prohibited in A213.	Seamless or Welded. Both types are covered under this standard.
Mechanical Test (Tension)	Mandatory. Every lot must pass TS/YS/EL tests as per A1016.	Not mandatory. Usually not required unless explicitly specified by the buyer.
Hardness Test	Mandatory for all grades. Strict limits for Ferritic and Austenitic steels.	Required, but limits are generally more generous compared to A213.
Wall Thickness Policy	Minimum Wall (MW) is standard. Allows 0% negative tolerance.	Nominal/Average Wall (AW) is standard. Variations (+/-) are permitted.
ASME Compliance	Fully compatible as SA213 (ASME Section II). Approved for pressure vessels.	No SA269 equivalent. ASME Section II does not recognize A269 for code use.

Technical Comparison: ASTM A213 vs. ASTM A249 (Comprehensive)

Comparison Point	ASTM A213 (Boiler/Heat Exchanger Tube)	ASTM A249 (Welded Austenitic SS Tubes)
Full Title	Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes.	Welded Austenitic Stainless Steel Boiler, Superheater, Heat-Exchanger, and Condenser Tubes.
Manufacturing	Seamless only. Welded types are not permitted in A213.	Welded only. Intended for welded austenitic stainless tubing.
Weld Seam	Not applicable (seamless).	Weld seam quality is a key requirement; welded tube inspection/qualification is required.
Mechanical Test (Tension)	Mandatory. Every lot must pass TS/YS/EL tests as per A1016.	Required per A249 requirements (including test frequency and acceptance criteria defined by the standard).
NDE / Leak Test	NDE and/or hydro per A1016 / purchase spec (ECT/UT/HT etc. project dependent).	Typically requires NDE for welded tubing (e.g., weld seam examination and leak test such as hydro/air-under-water or other permitted methods).
Wall Thickness Policy	Minimum Wall (MW) is standard. Allows 0% negative tolerance.	Welded tube tolerance rules apply per A249; purchasing typically specifies OD/WT and inspection level.
Typical Use	Critical boiler/HRSG and heat exchanger service where seamless construction is required.	Heat exchanger and condenser service where welded austenitic stainless tubing is acceptable/standard.
ASME Compliance	Fully compatible as SA213 (ASME Section II). Approved for pressure vessels.	Commonly referenced as SA249 for ASME applications depending on code/purchase specification.
