Pipes & tubes inspection ensures quality control at different stages of the logistics chain, minimizing trade risks associated with specification deviations, discrepancies in quantity, or incomplete documentation for export and import operations.

CISS GROUP provides pipes & tubes inspection services for major metallurgical holdings, processing plants, pipes & tubes suppliers, and international metal trading companies. These services cover procurement, storage, loading, and unloading at intermediate warehouses and global ports.

Pipes & tubes inspection is conducted in accordance with ASTM standards. The process includes checks for surface defects such as mechanical marks, delamination, breaks, and other visible imperfections. Welded seams are examined for porosity, undercuts, unevenness, and excess or insufficient welding material.

Accredited inspectors and laboratory technicians from CISS GROUP conduct inspections at every stage of the supply chain.

The main stages of pipes & tubes inspection:

Incoming and outgoing pipes & tubes inspection

This stage includes procurement, delivery to warehouses or ports, and removal from metallurgical enterprises. CISS GROUP inspectors assess storage conditions, verify markings and color coding, inspect pipe surfaces for defects, measure outer diameter, wall thickness, length, and bevel angle, count the number of pipes, and collect samples.

Container and vessel hold cleanliness inspection

A visual inspection ensures the cleanliness and suitability of containers and vessel holds for pipes & tubes transportation. Inspectors examine internal surfaces, assess the integrity of locks, hinges, and fasteners, and check rubber seals on container doors and hold covers.

Loading process monitoring and sampling

During loading, inspectors oversee operations, confirm gross and net weight, and conduct weight checks using the draft survey method. They monitor the fumigation process, visually assess cargo quality, and collect samples according to international sampling standards. At the end of loading, inspectors seal containers or holds and document findings in real-time reports. CISS GROUP provides 24/7 inspection and sampling services.

Laboratory analysis of pipes & tubes quality

Quality testing is conducted exclusively in accredited laboratories following international contractual standards.

• Chemical composition analysis is performed according to approved standards, calculating the mass fraction of constituent components using precise formulas.
• Impact bending tests assess material toughness by subjecting specimens to impact failure on a pendulum impact device.
• Mechanical aging tendency is evaluated through material deformation, including tension, heating, and impact bending tests.
• Tensile tests determine yield strength, ultimate strength, elongation, and contraction after fracture.
• Flattening, expansion, and bending tests visually inspect for cracks and tears.
• Hydraulic pressure testing uses water or another liquid as a pressure-transmitting filler. A test is considered successful if no leaks or internal diameter changes occur.
• Welded seam inspection is primarily conducted using ultrasound technology for precise defect detection.

Photo and video reporting

Each inspection stage is documented through photographs and videos, timestamped for accuracy. Upon completion, CISS GROUP provides a detailed photo report covering all inspection and control stages.

Certification

Following the inspection, final certificates or reports are issued. Clients can verify document authenticity via a unique QR code, granting access to digital certificates on the CISS GROUP website. Digital cryptographic signatures ensure security and reliability.

Digitally signed certificates are often required by banks for trade financing verification, particularly in letter-of-credit transactions.
