Al-Infiraj group (Sunshine Co.) supplies the oil and industrial projects with pipes from global origins. These pipes are manufactured according to the internationally approved standards. The Group has a great scientific experience in evaluating such pipes as for the metal used in their production, method of production (Seam and Seamless), dimensional measurements and the mechanical and physical properties required by the field applications of such pipes concerning the strain, toughness, corrosion resistance, weldability… etc.

The Group's activity is currently focused on the supply of pipes for the oil industry in accordance with the API and the ASTM standards. The methods internationally used in manufacturing small and large pipes can be outlined as follows:

1. Seamless tube and pipe:
   • Pierce and pilger rolling process.
   • Plug rolling process.
   • Continuous mandrel rolling process.
   • Push bench process.
   • Pierce and draw process.
   • Tube extrusion process.
   • Cross rolling processes.
     • Assel rolling process.
     • Diescher rolling process.
2. Welded tube and pipe:
   • Pressure welding processes.
     • Fretz-Moon process.
     • Electrical resistance welding.
       • DC processes.
       • Low frequency processes.
       • Higher frequency processes.
   • Fusion welding processes.
   • Submerged-arc welding process.
   • Gas-shielded arc welding processes.
   • Longitudinally welded pipe (U-ing / O-ing process).
   • Spiral pipe.
     • Spiral pipe in integrated forming and SAW welding lines.
     • Spiral pipe with separate forming and SAW welding lines.

Below are tables of the metallurgical and mechanical standards of the pipes used in the oil industry.
