Casing And Tubings

Our casing and tubing pipe are manufactured according to API grades and also in proprietary grades including sour, high collapse, chrome and CRA products for special applications. All of our products are manufactured to the most exacting quality standards. We hold a global ISO 9001 registration for our operations, which follow a uniform quality policy and apply a rigorous quality management system.

Maintain borehole stability
Prevent contamination of water sands
Isolate water from producing formations
Control well pressures during drilling, production, and work over operations
Casing provides locations for the installation of:
Blowout preventers
Wellhead equipment
Production packers
Production tubing

The cost of casing is a major part of the overall well cost, so selection of casing size, grade, connectors, and setting depth is a primary engineering and economic consideration. Casing strings There are six basic types of casing strings: Conductor casing Conductor casing is the first string set below the structural casing (i.e., drive pipe or marine conductor run to protect loose near-surface formations and to enable circulation of drilling fluid). The conductor isolates unconsolidated formations and water sands and protects against shallow gas. This is usually the string onto which the casing head is installed.
