PIPE CONNECTION SYSTEM FOR STEEL PIPES USING MECHANICAL FITTING WITHOUT ON-SITE WELDING.
PSS provides services of steel pipe connection by means of mechanical fitting.
Mechanical fitting in the connection of steel pipes is the result of plastic and elastic deformations, which create extremely significant radial strains. These strains can exceed the resistance to pressure of the structure of the pipe and of a traditional welding technique.
The connection system consists in the insertion of two steel pipes. One of the ends is first expanded or flared (the BOX) and the other end (the PIN) is prepared for insertion into the BOX.
This technology is widely used around the world, especially for upstream and midstream OIL & GAS.
This pipe joint has greater resistance and tightness than that of traditional welding, with the following advantages and savings:
No welding on site
No X-Ray inspection on site
Fewer workers involved
Versatility and flexibility of the operation
Safer and more ecologically-friendly operation
No need for fire, flames or heat in environmentally sensitive areas.
Minimum speed of installation 650m/day
For pipes with diameters of between 2 3/8” and 12‘’
Up to X60 Grade Steel
For wall thickness of up to SCH 160
