More preferably, the tensioning pup has a series of gradations marked on the pup for measuring the amount of tension applied to the tubing string.
A horizontal spool tree assembly includes a spool body or housing (12) and a tubing hanger (18, 118, 218, 318) supporting a tubing string in a well.
The flexible shaft and ball cutter are then removed and a flexible tube having a nozzle blaster (46) on an end thereof is then inserted into the upset tubing in the channel.
The hanger retainer is then engaged with the tubing hanger for suspending the tensioned tubing from the dognut locked in the wellhead.
Tubing is tied on the drive to transmit reciprocating motion.
The invention relates to a novel compact fluorescent lamp comprising a helicoid discharge tube (2) and a tube piece (8) which is connected thereto and can be used for accommodating an Hg source (14) and also as an exhaust tube.
The present invention relates to a well pumping equipment comprising a pump (1) with an electric motor (2) that have their bodies placed into the well using a pumping and compressor pipe (3).
The withdrawal tube is connected to a collection chamber which itself is under vacuum to cooperate in the removal of the blood and any maintenance fluids from the pump-tube apparatus for collection in the collection chamber.
Upon these two cantilever units the concrete pumping tube is pivotally arranged and may be easily operated over circular surface with the entire length of the distribution tube as radius.
The extracorporeal blood circuit comprises an expansion chamber (24) for an infusion fluid connected to a second conduit (28) by a pump tube coupled to a tube- deforming pump.
Also, process steps associated with evacuation through an evacuation tube are eliminated.
The fluid accumulator is connected between the branch pipe (31) of the actuating cylinder and the fluid inlet port (52) of the pumping tube (20) in order to drain the hydraulic fluid to the pumping tube (20).
The expansion piston in turn drives the pump piston housed within the pump tube by means of a rod connecting the two pistons.
The stability of the performance is found to be dependent on a ratio between a length of the pump tube and a wavelength of a wave which is caused by the pump in the pump tube during operation.
The oil pipes (4) is provided within the a piston rod (1-8) being a centre rod.
A trawl for use with the procedure is provided with a fishing pump, pumping pipe and power transmission.
Preferably the same amount of liquid is pumped during the upward movement of the pumping tube (30) as during the downward movement.
