Perforation density and dimensions are available in standard or selected types.
Each perforation bore is thoroughly inspected and cleaned of burrs at the internal and external pipe side. Perforation density and dimensions are available in standard or selected types. Each perforation bore is visually inspected and cleaned of burrs at the internal and external pipe side.
We use modern CNC machines and equipment for seamless perforated pipes manufacture.

MODELLING
For perforated pipes tough service conditions (torsion or heavy axial loads) our engineers adjust the maximum perforation slots number per meter keeping required mechanical properties of pipes or pipes assemblies. The load calculation is carried out separately for a pipe and a construction (with assembly load).


Properties modelling for horizontal well holes with torque impact conditions is also available.
