product intro
the perforated casing pipe with cutting edge technology,which is manufactured with carbon steel or stainless steel,used for the application of oil reservation layer without much sand or for application of prewents the rock bits dropping off the well bore.
The overall strength of the drilling of the base pipe and is only 2 to 3% smaller than the standard casing or tubing. Therefore, it can withstand compression deformation class have sufficient overall strength. Even if the local deformation, compression portion of the gap can not be enlarged.
feature
1.Every joint perforated by us is deburred internally and externally
2.each holie is visually inspected and burrcleaned
