This specification ensures pipes with consistent weld quality, exceptional mechanical strength, and superior corrosion resistance.

Stainless Steel Pipe Manufacturing (ASTM A358) Process Flow:

Raw Materials: Stainless steel plate/coil selected per ASTM/EN grades.
Forming: Plate is roll-formed into cylindrical shape.
Thick Wall Welding: Using Electric Fusion Welding (EFW) for full joint integrity.
Heat Treatment: Normalizing/stress relief to restore microstructure.
Non-Destructive Testing: 100% radiographic/ultrasonic inspection per ISO/ANSI standard.
Hydrostatic/Destructive Testing: Ensures pressure rating, safety.
Surface Finishing: Pickling, passivation, customizable polishing.
Packing: Ends capped, wrapped for international sea/land transport.

Product Technical Data: Steel Pipes - ASTM A358

Standard	Material Grade	Diameter Range	Wall Thickness	Finish	Max Length	Testing & QA
ASTM A358	304/304L, 316/316L, 321, 347	8" to 60" (219-1524mm)	5mm to 40mm (Sch.10S ~ XXS)	Pickled, Passivated or Polished	Up to 12m (customizable)	RT, UT, Hydrostatic, PMI

RT (Radiographic Testing): Ensures weld integrity and detects sub-surface flaws.
UT (Ultrasonic Testing): Used for wall thickness and lamination checks.
PMI (Positive Material Identification): Ensures grade compliance—crucial for critical projects (offshore, pharma, etc.).
Third-party inspection: SGS, BV, Lloyd’s available as per project compliance.

Stainless Steel Pipe: Material & Technical Advantages

Stainless steel pipe resists a broad spectrum of chemical and abrasive corrosion, making it optimal for petrochemical, water, and food/pharma use.
Mechanical properties such as a yield strength up to 205 MPa (Grade 304/316/321/347 - ASTM compliant) and tensile strength up to 515 MPa ensure high-pressure, high-temperature performance.
Surface passivation enhances pitting and crevice corrosion resistance (tested per ASTM A380, EN 10088-2).
Life expectancy often exceeds 50 years even in aggressive settings, reducing replacement frequency and lowering total lifecycle cost.
Compliant with global certification standards: API 5LC, PED 97/23/EC, NACE MR0175/FDA/ISO 9001/SGS, ensuring end-to-end traceability and quality control.

FAQ: Stainless Steel Pipe Technical Terms & Expert Answers

Q1. What is ASTM A358 specification for stainless steel pipe?

ASTM A358 covers electric-fusion-welded austenitic stainless steel pipe for high-temperature and corrosive service, made from plate or strip. It specifies wall thicknesses, grades, and testing regimens.

Q2. What is the difference between seamless and welded stainless steel pipe?

Seamless pipes are made from solid billets and have no weld seam—ideal for highly critical service. Welded pipes (like ASTM A358) offer robust weld quality and are cost-effective for large diameters and longer lengths.

Q3. What does 316L or 304L grade mean for stainless steel pipe?

316L contains molybdenum for enhanced pitting/crevice corrosion resistance (especially with chlorides), while 304L is low-carbon for improved weldability and reduced intergranular corrosion risk.

Q4. What is PMI and why it is critical?

PMI (Positive Material Identification) uses X-ray or optical analysis tools to verify the alloy composition—crucial to guarantee material compliance for safety-critical infrastructure (oil, pharma, nuclear sectors).

Q5. What is the acceptance criteria for weld testing under ASTM A358?

ASTM A358 requires full radiographic examination of each weld pass. Acceptance is per ASME Section VIII or customer project’s stricter criteria, ensuring zero defect or only minor, non-critical flaws.

Q6. What's the installation standard for stainless steel pipe in process plants?

ASME B31.3 (Process Piping), EN 13480, and ISO 1127 are commonly referenced. These cover design, fabrication, and installation tolerances, supporting international project compatibility.

Q7. Are your pipes compliant with international third-party certifications?

Yes. Steel Pipes - ASTM A358 can be supplied with Lloyd’s, SGS, TÜV or DNV inspection or per customer’s nominated international body requirements.
