Welded Casings for drilling and well construction
Drilling crews use Welded Casings to protect the wellbore, isolate formations, and support the casing structure during well construction. These casings fit oil, gas, geothermal, and water well applications.
Manufacturers produce welded casing by ERW or Spiral Submerged Arc Welding. Therefore, buyers should choose the casing based on size, wall thickness, steel grade, connection type, and project requirements.

Casing Type Guide
Conductor Casing: Crews install it as the first and widest casing section. It stabilizes loose surface formations and supports the drilling rig.
Surface Casing: Crews use it to protect shallow zones. Also, it supports BOP installation and helps isolate freshwater aquifers.
Intermediate Casing: This casing helps manage pressure changes, unstable formations, and reactive shale during drilling.
Production Casing: Crews run it across the reservoir zone. As a result, it supports production and helps maintain well integrity.
Liner: Crews use it to cover a selected interval when the well plan does not require full-length casing.
Ordering Information
Before ordering, check the required size, diameter, steel grade, wall thickness, welding method, connection type, length, and order volume.
