A pup joint is a type of drill pipe used in oil and gas drilling operations. It is a shorter length of drill pipe that is used to connect two longer sections of pipe to make up the desired total length of the drill string.
Pup Joint, also referred to as Riser Spool, or Surface Riser Spool is a pressure-containing piece of equipment having end connections, used below or between drill-through equipment. The Spacer spool is a wellhead section that has no provision for suspension of tubular members and which may have no provision for sealing of tubular members. It is used to provide separation between two components with equal-sized end connections. providing exceptional performance as a wellhead extension, securing connection for choke manifold and kill manifold.
A. Flanged, studded, and rubbed ends are available in any combination.
B. We can produce a spacer spool for any combination of size and pressure ratings.
C. Integral forged material ensures excellent reliable working performance.
D. spacer spools are designed to minimize length while allowing sufficient clearance for wrenches or clamps unless otherwise specified by the customers.
E. The standard Spacer Spools do not include outlets, although outlets can be added as per request.
F. Our spacer spool is suitable for general working conditions and sour service.
G. Stainless Steel 316L or Inconel 625 corrosion-resistant alloy ring grooves are also available.
H. Normally we will provide tap-end studs and nuts with studded-end connections.

Making up the desired length of the drill string: Pup joints are used to connect longer sections of drill pipe to make up the desired total length of the drill string, which can range from several thousand feet to tens of thousands of feet.
Adjusting for changing borehole depths: As the drilling operation progresses and the borehole depth changes, pup joints can be added or removed from the drill string to adjust its length and maintain the desired level of tension and torque on the drill bit.
Providing a means of compensation: Pup joints can be used to compensate for tool joint wear or to accommodate a change in tool joint size. This helps to maintain the strength and integrity of the drill string over the course of the drilling operation.
Facilitating the removal of stuck drill pipe: Pup joints can be used to help remove stuck drill pipe by providing a place to attach a fishing tool or by providing a location for applying additional force to the drill string.
A pup joint is a type of drill pipe used in oil and gas drilling operations. It is a shorter length of drill pipe that is used to connect two longer sections of pipe to make up the desired total length of the drill string. The pup joint is typically used to adjust the length of the drill string to accommodate the changing depths of the borehole as the drilling operation progresses. Pup joints play a critical role in the drilling process, helping to ensure the efficiency, safety, and success of the operation.
APImeivalve manufactures short sections in a variety of sizes, pressure ratings and thread profiles to meet any requirement. Our pipe stubs are made from seamless pipe and are machined or upsold to the final size. All API casing and tubing stubs are manufactured in accordance with API Spec 6A. Special requirements are available upon request.
