A landing nipple, adaptable to be made up in a tubing string having a sliding sleeve disposed in its bore for selectively providing communication of balance and control pressure fluid to the nipple bore. When the sleeve is shifted to its first, upper position, balance fluid is conducted via the nipple to a tubing retrievable safety valve placed in the tubing string below the nipple. In the event the tubing retrievable safety valve is taken out of service, a secondary safety valve can be landed in the nipple, the sleeve shifted to its downward, second position, opening sleeve ports for conducting control and balance fluids to the landed, secondary safety valve. The nipple has a failed closed safety system provided by the novel arrangement of nipple entry ports for balance and control fluid, in that the control fluid entry port is in between two balance fluid ports and their seals, so that failure of the pressure seal exposed to tubing pressure causes tubing pressure to enter the balance pressure system closing the tubing retrievable or secondary safety valve, whichever is presently in service Romania landing nipples, chad landing nipples , nigeria landing nipples , bahrain landing nipples , seria landing nipples , russia landing nipples , uae landing nipples , iraq landin gnipples , yemen landin gnipples , oman landing nipples

Description: casing rollers are simple, rugged tools for restoring buckled, collapsed, or dented casing to its normal diameter and roundness. There are no pins, springs or other small parts to break or lose in the hole, making it safer to use and easier to maintain than other rollers. Operation is very simple, requiring only ample fluid circulation and slow rotary speeds. Features: casing rollers are composed of a mandrel with a series of eccentric roll surfaces, each of which is assembled with a series of heavy-duty rollers. These rollers are secured by a nose cone which is locked to the mandrel by a series of husky ball bearings, running in a race between the nose cone and lower mandrel end. These tools may be redressed to roll a larger size by changing the rollers to proper oversize rollers. The casing roller is equally effective using right- or left-hand rotation and left-hand connections will be furnished on request. Lower stinger connections may be furnished on a special nose cone or on the lower mandrel end on request, at additional cost. Wooden cases

Description¡êothe casing scraper is ideal for the removal of mud, cement, bullets, rust, scale, paraffin, perforation burrs and other obstructions from the inside walls of casing. Maintaining a clean casing i.D. Is important when operating drilling, fishing, or wire line tools. Likewise, packers, patches, spears, and similar tools require clean surfaces to grip. Obstructions on casing walls will frequently cause these tools to fail or become difficult to operate. Construction: Utilizing a simple one-piece mandrel design, the bowen casing scraper is constructed to be rugged, yet simple to operate and maintain. The scraper conditions 50 percent more surface area than any other tool on the market. The full circle blades are so spaced to contact 600¡ã (almost two complete circles) of casing surface at once. Short and compact, the scraper also incorporates a long taper on the blades for passing through joints without hanging. The scraper works in vertical or rotary operations and may be run on drill pipe or wire line. Bowen casing scrapers are available to condition pipe ranging from 2-3/8-inch tubing to 13-3/8-inch casing. For more information on the use, operation and specifications of the scraper contact your national oilwell representative. Wooden cases
