Extrusion process for tubular member

An extrusion system, comprising:

• a perforated tubular member having a perforated tubular member length disposed between a perforated tubular member first end and a perforated tubular member second end, said perforated tubular member having a perforated tubular member external surface and a perforated tubular member internal surface defining a perforated tubular member passage between said perforated tubular member first and second ends;
• a fluid injector having a fluid injector internal flow path terminating in an annular outlet disposed adjacent said perforated tubular member first end, said annular outlet aligned with said perforated tubular member internal surface proximate said perforated tubular member first end to conduct an amount of coolant to said perforated tubular member internal surface;
• said fluid injector having a fluid injector bore wall defining a fluid injector central bore disposed adjacent said perforated tubular member first end, said fluid injector bore wall aligned with said perforated tubular member internal surface;
• and
• a jacket assembly including a tubular jacket having a tubular jacket length disposed between a tubular jacket first end and a tubular jacket second end, said tubular jacket first end coupled to a retaining plate and said tubular jacket second end coupled to a mounting flange to define a jacket assembly internal space fluidically coupled to said fluid injector central bore, said retaining plate having a retaining plate bore wall which defines a retaining plate central bore aligned with said fluid injector central bore, said mounting flange having a mounting flange bore wall which defines a mounting flange central bore aligned with said fluid injector central bore.

A method of producing an extrusion system, said method comprising:

• providing a perforated tubular member having a perforated tubular member length disposed between a perforated tubular member first end and a perforated tubular member second end, said perforated tubular member having a perforated tubular member external surface and a perforated tubular member internal surface defining a perforated tubular member passage between said perforated tubular member first and second ends;
• providing a fluid injector including:
• a fluid injector bore wall defining a fluid injector central bore;
• and
• a fluid injector annular internal flow path which inwardly tapers to terminate in an annular outlet disposed about said fluid injector central bore;
• disposing said fluid injector central bore wall adjacent said perforated tubular member first end to align said fluid injector bore wall with said perforated tubular member internal surface disposing said annular outlet adjacent said perforated tubular member first end;
• and
• aligning said annular outlet with said perforated tubular member internal surface of said perforated tubular member first end to conduct coolant to said perforated tubular member internal surface.
