DrillingForGas.com - Mechanical sand control methods

Stainless steel wire (304 or 316 grade) is generally used because of its superior abrasion and corrosion resistance. The wire is usually wrapped on normal grade carbon steel tubulars for non- corrosive environments. The manufacturing of wire wrapped screens is a semi-automated process. Hence screen design can be adapted to suit particular needs.
