Product Description

TUBING DRAIN /BLEEDER VALVE 


 

Tubing drains allow you to reliably drain the production tubing before pulling out of a hole. This prevents the process of pulling wet tubing, which is difficult and not environmentally friendly. Once on a surface, the tubing drain can be redressed for future use.

When installing the tubing drain, it is recommended to place the drain one or two joints above the top end of the pump. The tubing drain works off of pressure activation. You can change the shearing rating of the tubing drain by adding or removing shear screws. Once the screws shear, the sliding sleeve drops down and allows the production fluid to drain out.

Tubing drains can be activated by pressure at the surface to circulate the debris or solids from the packer or anchor and around equipment. It provides a positive way of releasing and/or circulating the fluid from within the tubing string without mechanical manipulation.

•  
• Advantage 
• Industry standard, economical design
•  seals standard (back-up rings not required)
• Brass screws provide consistent and accurate shear values while reducing wear on steel parts, permitting reuse
• Beveled edges on bottom and top to ensure drain slides past casing patches or other casing issues
• Multiple rebuilds allowed, reducing total cost of ownership
