Pup Joint

Description

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.

Features

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.
