At Quality Industrial Services, we offer a wide range of specialized services tuned for the petrochemical industry. Those include:

1. Site Inspection

In the petrochemical sector, site inspections form the foundation of quality assurance. Quality Industrial Services inspectors conduct on-site evaluations during all project phases, including construction, operation, and maintenance, to verify compliance with engineering specifications, codes, and safety regulations.

Our specialists assess material conditions, welding quality, corrosion levels, and operational readiness. These inspections help detect early signs of degradation or nonconformance, preventing costly failures and ensuring equipment longevity.

  • Certified Welding Inspection (CWI): Performed by AWS-certified inspectors to verify weld quality, joint preparation, and documentation.
  • Pressure Vessel Inspection (API 510): Detailed inspection and assessment of pressure-retaining equipment to ensure mechanical integrity.
  • Piping Inspection (API 570): Inspection and verification of in-service piping systems to prevent leaks, corrosion, and structural failure.
  • Tank Inspection (API 653): Inspection and evaluation of aboveground storage tanks, ensuring compliance and preventing costly downtime.
  • Coatings Inspection (NACE): Corrosion control and coating system verification by certified NACE inspectors.
  • NDT Inspection: Advanced non-destructive testing, including UT, RT, MT, PT, and VT to detect internal or surface-level discontinuities.
  • Equipment & Maintenance Inspections

We provide comprehensive inspection and condition monitoring for a range of equipment types, including:

  • Fixed Equipment (tanks, exchangers, reactors, and vessels)
  • Rotating Equipment (pumps, compressors, turbines)
  • Electrical & Instrumentation (E&I) Equipment

2. Vendor Surveillance and Source Inspection

Before materials or components are shipped to a site, vendor surveillance and source inspections verify that manufacturing processes meet project and client specifications. Quality Industrial Services inspectors monitor fabrication, witness testing, review documentation, and verify traceability of materials. This minimizes the risk of receiving nonconforming or defective equipment, saving time and cost during project execution.

Quality Industrial Services ensures that your vendors and suppliers meet strict quality standards. Our experts conduct:

  • Shop and Source Inspections: Monitoring manufacturing processes, materials, and final assemblies before shipment.
