5CT Seamless Tubing Pup Joint for Well Completion - Durable Quality

Pup Joint, also called tubing/casing short joint, is manufactured from seamless alloy steel tube in lengths shorter than standard full-length tubulars. Produced strictly per API Spec 5CT and API Spec 5B thread standards, it matches the same steel grade, wall thickness and thread form as regular tubing and casing.

It is widely applied during well completion and workover operations to fine-tune total string length, precisely position downhole tools like packers and pumps, and mark depth sections in boreholes.

We supply two main types: downhole tubing/casing pup joint and high-pressure surface flow line pup joint. The surface pup joint adopts integral forged steel body with anti-corrosion red coating, connected by hammer union for high-pressure well control manifolds. All pup joints come with plastic thread protectors, anti-rust thread compound and custom length support, stable under high pressure, hydrogen sulfide and seawater corrosive environments.

• Consistent mechanical performance with matching tubing/casing, no weak point in tubular string
• Full API certification, precise thread machining for zero leakage under high well pressure
• Multiple fixed short lengths & custom size available for accurate depth adjustment
• Two product series for downhole tubular string and high-pressure surface flow lines
• Replaceable thread protectors avoid thread damage during transport & running
• Anti-corrosion coating optional for marine and sulfur-bearing well environments
• Compact size, easy loading, transportation and on-site rig operation
• Perfect matched with casing head, BOP, choke manifold as complete well control set
