We provide a comprehensive range of Non-Destructive Testing (NDT) methods to verify the internal and surface integrity of every welded joint. Depending on the material and application, our capabilities include:

  • Visual Testing (VT): 100% continuous inspection of fit-ups, root passes, and final weld profiles by our quality team.
  • Radiographic Testing (RT): Volumetric X-ray or Gamma-ray inspection to detect internal subsurface flaws in critical, high-pressure joints.
  • Ultrasonic Testing (UT): Advanced volumetric testing for internal flaw detection and thickness verification, primarily in thick-walled or large-bore piping.
  • Magnetic Particle Testing (MT): High-sensitivity surface and near-surface crack detection for ferromagnetic materials like carbon steel.
  • Dye Penetrant Testing (PT): Surface defect inspection specialized for non-ferromagnetic materials, including Stainless Steel, Duplex, and Titanium.

Yes, we have executed multiple projects involving high-pressure steam, condensate, and process piping systems.

We maintain weld maps, joint numbering systems, and daily progress records verified by QA/QC personnel.

Yes, we have hands-on experience in HDPE fusion welding using our own qualified machines and personnel. We have also executed lamination joints for FRP/GRP piping systems across multiple projects.

Comprehensive documentation includes MDR, WPS/PQRs, material test certificates, hydrotest reports, NDT records, and final QA/QC dossiers for client and statutory approval.

The extent of our NDT—ranging from spot checks and percentage-based sampling (e.g., 10% or 20%) up to 100% full radiography/ultrasonic coverage—is strictly governed by your project specs, fluid categories, and design codes like ASME B31.1, ASME B31.3, and IBR regulations.

To ensure unbiased quality compliance, we coordinate all critical testing with leading Third-Party Inspection Agencies (TPIAs). Every test is fully logged with unique joint mapping, welder identification numbers, and NDT traceability reports officially endorsed by the TPIA for your final handover package.

SFE has proven capabilities in welding advanced Materials of Construction (MOC) including Stainless Steel (304, 316, etc.), Duplex, Super Duplex, Titanium, and Jacketed systems. To preserve material properties and guarantee joint longevity, we execute strict specialized pre- and post-welding activities.

  • Purging Protocols: For exotic materials like Stainless Steel and Titanium, we implement rigorous internal argon purging to prevent root oxidation during welding.
  • Pickling & Passivation: Post-weld chemical cleaning via pickling and passivation is performed on all stainless steel and corrosion-resistant alloys. This removes welding oxides and restores the chromium-rich passive layer, guaranteeing maximum corrosion resistance.
  • Preheating & Post-Weld Heat Treatment (PWHT) / Stress Relieving: For heavy-wall carbon steels, alloy steels, and specific code-mandated applications (such as IBR high-pressure steam lines), we perform controlled preheating and localized or furnace-based stress relieving. This alleviates residual welding stresses and prevents hydrogen cracking.
  • Contamination Control: We maintain dedicated fabrication areas and specialized tooling for stainless steel and exotic alloys to prevent cross-contamination from carbon steel carbon dust.
