flanged side entry sub

Sub-drill's Flanged Side Entry Sub with 'replaceable side outlet' offers an alternative solution to issues with existing product design and reduces costs and increases efficiency for Rig Operators. 

As a proven and trusted designer and manufacturer of subsea tools and drilling equipment to the global energy industry for over 30 years, Sub-drill has continued to develop its range of subsea, rig-floor, drill stem and downhole products to enhance and improve the safety and efficiency of offshore O&G operations.

Included in the Sub-drill line-up of drill stem products is our range of Flanged Side Entry Subs as we continue to provide clients with innovative, competitively priced and reliable product solutions which do not compromise on quality or performance.

In addition to our long standing reputation for product quality excellence, further reassurance is provided to our customers by the provision of 3rd party design verification from DNV and ABS on both the side entry subs themselves and the flanged side outlet design.

Manufactured in a variety of configurations with both single and dual outlets (double dutch), and with working pressures up to 15,000psi, our side entry subs are available with most types of drilling connections, multiple sizes of side outlets, and a variety of dimensional configurations to suit individual operating requirements.

Key advantages

• Flanged design offers a reduced cost as compared to integral design.

• Manufactured from one piece of steel for operational strength and performance.

• Unique replaceable bolt-on flanged side outlet design provides a solution for repair as opposed to the potential of having to scrap the entire sub when damaged.

• Use of reduced material size minimises potential for hardness/strength variations in critical areas.

• Avoids welding and stress relief issues with fabricated subs.
