Drilling spools are designed to allow the smooth circulation of mud during the drilling environment. This pressure-containing piece of equipment, with end connections and outlets, is placed below or between the drill-through equipment (BOP). Drilling spools usually have the same nominal top and bottom end connections. Side outlets may differ from each other. Top, bottom, and side end connections can be hub end or flanged. This is like a riser spool and has side outlets to connect with choke and kill manifolds.
Hydro manufactures all sizes, pressure ratings, temperature ratings, and lengths of drilling spools with top and bottom flanges complying with API 6A and MSS SP-44. The API 16A hub clamp end connectors and the side outlets conform to API 6A, ANSI B16.5 flanges, API 16A hub clamp end connectors, and hammer unions as required by the customer.
Hydro repairs, re-manufactures, and modifies existing spools, such as top and bottom flange replacements, side-outlet modifications and replacements, new cladding, or cladding replacement from stainless steel (SST) to corrosion-resistance alloy (CRA). We also certify all parts to meet API 16AR latest specifications.
Our standard recertification inspection covers blast cleaning, hardness survey, minimum wall thickness survey, magnetic particle testing (MPI and MT) on all accessible surfaces, and liquid penetrant testing (LPT and PT) on any SST or CRA inlaid ring grooves, dimension inspection, and drift passing.
An adapter is a pressure-containing piece of equipment with end connections of different nominal sizes or pressure ratings. It is used to connect other pieces of equipment of different nominal sizes or pressure ratings.
Hydro manufactures adapters with bolt holes and studded types. Adapters can be supplied with either SST inlays for API 16A or CRA inlays for API 6A and API 16A.
Hydro can provide various lengths to accommodate the rig requirements. Hydro can also create a short-length adapter that meets API standards.
Monogramable double studded adapters (DSA and DSAF) can be supplied with API 20E BSL2 bolting. Hydro can also provide DSAs with side outlets of any profile.
Hub Clamp End Connector
A hub clamp end connector is a compact mechanical joint consisting of four basic elements – namely hubs, seal, clamp assembly, and bolting.
During assembly, both hubs inside the clamp are drawn together under the twin wedge shape in the clamp segments and provide a self-energising seal.
Hydro designs and manufactures and monograms API 16A clamps and hubs (hub clamp end connectors) as required. We have designs for all types of clamps meeting API 16A specifications and our designs are in compliance with API 6AF2.
BENEFITS AND FEATURES:
Only four bolts to tighten and no alignment required.
Comes with bolts, nuts, and load-bearing rings. Hydro can provide swivel-lifting eyes on larger sizes to make handling easy, quick, and safe.
