Float subs factory full#
Float subs are available in a variety of sizes to accommodate the full spectrum of downhole drill stem sizes.
They prevent back flow of cuttings from plugging the drill bit jets when making connections. NOTE: Upon request, connection threads can be treated to prevent galling during make-up. Float subs are used to house the float valve within the BHA providing fluid flow control through the ID of the drill string. Crossover subs adapt to different size drill pipe connections to drill collars, or drill collars to drill collars. Manufactured from alloy heat treated steel, our subs meet API import matplotlib.ticker as mtick (mtick.FormatStrFormatter. Saver Subs are typically used in conjunction with a drilling rig's Kelly or Top Drive transmission.ĭrilling Tools International offers cross-over subs and bit subs for any drill string connection size and function needed. The saver sub connection is sacrificed because it can easilyīe repaired or inexpensively replaced. Saver subs are used to extend the life of the drill stem component it is made up to by taking the wear caused by multiple connections. Double side-entry subs are designed with a solid ID on one end made to pump through All circulating/pump-in subs are integral, one-piece design.Īll single and double side-entry subs are integral one-piece design tested to 1 1/2 times safe working pressure.
Integral Circulating Subs or Pump-In SubsĬirculating subs are made with a pin or box connection and includes a WECO figure 1502 union. Our pup joints can be ordered with an 18-degree taper or square shoulder and with pressed Pup joints are key components in special drilling operations when specific spacing considerations are required. See detailed information onĭrilling Tools' Diffuser™ downhole filtering technology. Muleshoe subs are designed to be used when pumps are turned off while directional equipment isĪvailable in a variety of sizes, Drilling Tools' filter subs range from the retrievable and non-retrievable mud screens to the Diffuser™ blade technology sub assembly. NOTE: UBHO subs are designed to allow mud flow while directional equipment is seated within the sleeve. They are available in steel or non-magnetic material. Survey equipment or mud motor scribe line. This sub contains a landing sleeve that can be oriented to the directional UBHO and muleshoe subs are used in directional drilling BHA's and are typically run directly below a non-mag drill collar. The sub's elevator recess and connections are machined to fit the elevator and drill collar connections, as per API specifications. Utilized during make-up or break-out operations. Lift subs are offered with a flow through or as a conventional design in a variety of sizes to provide ease of handling long products or heavy downhole BHA components. They prevent back flow of cuttings from plugging the drill bit jets Listedįloat subs are used to house the float valve within the BHA providing fluid flow control through the ID of the drill string. Virtually any type of sub can be manufactured in-house to customer specifications. The flapper also closes quickly keeping cuttings out of the drill string preventing plugging of the bit.Īll Float Sub IBOPs are extensively tested in our facilities to ensure the highest quality and that the product will perform to specifications when used in the field.Drilling Tools offers a variety of subs in both AISI 4145 heat-treated steel and non-magnetic metal. The flapper float assembly provides a completely unrestricted bore through the valve and is designed for highly abrasive fluids. The plunger (dart) float assembly offers positive and instant shut-off, assuring continuous control of fluid flow during drilling. Float Sub IBOPs are available in 5000 or 7500 PSI. The Float Sub IBOPs are available in one or two piece body construction and are supplied with either API or proprietary connections. Featuresĭ‑Valves manufactures the Float Sub IBOP body and sub from chromoly steel and uses third party, industry approved, plunger (dart) and flapper float assemblies. It also allows for downward fluid circulation within the drill string. The Float Sub IBOP is used to control back flow from high pressure formations through the drill string back to the surface when joints are added.
