Features of Perforated Pipes

Our perforated pipes use API J5/K55/N80 casing and tubing.With strong overall strength,the perforated pipes are not easy to deform;

 

The holes are uniform and smooth without burrs;

 

The whole pipe is anticorrosion treated to prolong the service life;

 

Easy to operate and to be connected with larger inner diameter;

 

Hole diameter and quantity can be customized.

 

Welding Technique:Electric Resistance Welding(ERW).

 

Standards:API 5CT, API5L, ASTM A312,ASTM A409,etc
