Casing & Tubing Couplings

Penguin supplies complete range of Casing and Tubing Couplings with  round threads and Buttress threads as listed below

Production Tubing Pup Joints

Pup Joints are used for adjusting the height of tubing or casing strings and the depth of downhole completion tools. PPSL manufactures Pup Joints in various OD sizes ranging from 2-3/8″ to 4-1/2″ nominal OD with standard wall thickness in 2 ft. to 15 ft. length configurations and in material grades J-55, K-55, L-80, N-80 and P-110..

Cross Over Subs

Cross Over Subs are manufactured from premium solid steel bar roots in short lengths and are used to change the size, weight or thread type in a down hole production or completion string. These subs are available in various sizes ranging from 2-3/8″ to 4-1/2″ nominal OD with standard weight or heavy wall and in various grades (J-55, K-55, L-80, N-80, P-110 etc.) in any end size/connection combinations per customer specified requirements.

Bull Plugs

Bull Plug is a threaded nipple with a rounded closed end used to plug a hole or close the end of a line. Penguin makes Bull Plugs specific to client requirements and specifications.

Flow Couplings

Flow Couplings are short, heavy walled connector components installed in tubing strings where turbulence is expected. They are designed to minimize and/or prevent the effect of internal erosive wear caused by fluid turbulence. Flow couplings are placed just above or below landing nipples, safety valves or control devices where turbulent flow problems are likely to occur.

Hydraulic Tubing Drain

PPSL designs and manufactures Hydraulic Tubing Drain in various configurations installed with Rupture Disc sourced from industry leaders like Fike USA. Hydraulic Tubing Drain is used with deep hole drilling tools, downhole devices and other drilling applications to provide an accurate method to equalize the fluid level in tubing strings without mechanical manipulation. The Hydraulic Tubing Drain may be used in conjunction with Hydraulic Actuation Equipment and serves as a means of draining tubing fluids to the wellbore after setting tools or firing perforating guns.

The Hydraulic Tubing Drain is operated by the differential pressure between the hydrostatic pressure in the annulus and the combination of hydrostatic and applied pressure in the tubing. The tubing drain can be used with any tubing conveyed application that requires drainage or that is activated by differential pressure, including Hydraulic Firing Heads.
