Straight-Filtered Casing Pipes

Straight-filtered drilling pipes are generally used to meet cracked, hollow, cavernous, watery levels in wells drilled in rocks such as massive, hard limestone, basalt, andesite, tuff.

Straight filter pipes are punched into 2 meter long plate sheets and then rolled into cylinders with cylinders of appropriate diameter. After the sheet metal is welded by gas welding method, it is shipped in 4 or 8 meters length by adding in desired lengths.
