TOOLS & SERVICE EQUIPMENT
The Hanger Spool with X-Mas Tree Manifold attached is then lowered and sealed on the hanger bushing. The union nut may now be made up by hand and a spanner wrench. The tree cannot now be rotated.Raise the tree assembly enough to remove the spider and slips. At this point, the well can be displaced and the packer set under complete pressure control.Final nipple up operations are then completed and the type PBPV back pressure valve is removed from the hanger bushing with a lubricator.
Flanged Drilling Spool (PFDS)
These are designed to allow unrestricted circulation of mud in the well and provide flexibility in arranging flow line openings in blowout preventor hookups. Studded or open faced ends and outlet connections can be provided. Generally hub of the flanged outlet is welded. Height of spool will vary form 24" -36". However spools as per specific need of customers can also be provided.
Valve Removal Plugs (PVRP)
All flanged or studded outlets on PARVEEN's casing heads, casing spools and tubing heads are threaded for valve removal plugs. All plugs have standard API Line Pipe Threads and are small enough to pass thru the valve to be removed. The plug is installed when the valve is to be removed and removed when the valve is to be installed.
Valve Removal Tool (PVRT)
These are generally pressure-balanced manual hydraulic tool designed for safe and reliable operations in the installation and removal of valve removal plugs, in order to install or replace a well-head outlet valve under pressure conditions.This tool is also designed to accommodate 2 1/16”, 2 9/16”, 3 1/8” Valve upto 10000 PSI WP. Adapter may be provided for use with 1 13/16”, 2 1/16”, 2 9/16”, 3 1/8” flanged valves and screwed end valves. Various sizes of valve removal plug sockets are also provided for the respective sizes of plugs.In the figure above, Needle Valve ‘A’ is located next to pressure gauge on manifold by-pass assembly and needle valve ‘B’ is connected to 1/2" NPT TEE on far end of manifold bypass assembly. Needle Valve 'C' is a bleeder valve located behind flange packing.
