Technological Process

Raw Material Inspection – Select and inspect high-quality steel billets or coils.
Forming – Roll or pierce the material into pipe shape (Seamless / ERW / SAW).
Welding – Join pipe edges by electric resistance or submerged arc welding.
Heat Treatment – Improve strength and toughness through controlled heating.
Sizing & Straightening – Adjust pipe diameter and ensure dimensional accuracy.
Non-Destructive Testing (NDT) – Check for internal and surface defects.
Hydrostatic Test – Test each pipe for pressure resistance and leaks.
Surface Coating – Apply anti-corrosion coating (Black varnish, FBE, 3LPE, etc.).
Marking & Inspection – Mark specifications and perform final quality checks.
Packaging & Delivery – Bundle, cap, and ship with Mill Test Certificates.

Our Advantages

Local Branch & Spanish Support :Our local branches offer assistance in Spanish; process your customs clearance and ensure a smooth process of importation.

Reliable Stock Availability:With adequate stock available, we can meet your requirements without any delays.

Secure packaging:Pipes are tightly wrapped in several layers of bubble packs and sealed airtight to protect the pipes from deformation and damage, assuring the integrity of the product during transit.

Fast & Effective Delivery:To anywhere in the world to meet your project deadlines.

Packing and Transportation

Packaging:

Pipe End Protection: Steel pipe ends are capped with plastic or metal caps to prevent damage and water ingress during transportation.

Bundling: Multiple steel pipes are bundled together and reinforced with steel or nylon strapping to ensure stability during transportation.

Anti-Corrosion Treatment: Upon customer request, the pipes can be sprayed with anti-rust oil or coated with moisture-proof film to withstand long-distance transportation.

Clear Labeling: Each bundle of steel pipes is labeled with information such as specifications, standards, length, and production batch number to facilitate storage and loading and unloading.

Transportation:

Sea/Container Transportation: Suitable for long-distance export. Steel pipes are loaded in bundles to avoid collisions.

Safe Loading and Unloading: Use a sling or forklift during transportation to prevent damage to the pipes and surface coating.
