Casing pipes with sleeveless threaded connection OTTM D 102-146 mm
Design advantages:
– low cost of pipe suspension due to the absence of couplings;
– equal passage of the connection;
– additional sealing barrier;
-reducing the cost of restoring casing violations
Casing pipes with sleeveless threaded connection “PREMIUM” D 102-146 mm
Purpose:
Designed for casing strings, casing and repair of vertical wells in oil fields.
Pipe size range 102 – 146 mm
Advantages of the NKM-M design:
reduction in the cost of the casing string due to the sleeveless connection
operation in wells with high curvature
outer and inner diameters provide equal passage of the connection
the tightness of the connection is ensured by the presence in the design of the internal radial seal “metal-to-metal”
external conical stop serves as an additional sealing barrier
Tubing pipes with gas-tight threaded connection “PREMIUM” according to specifications D 60-89 mm
Design advantages:
operation in difficult conditions of oil and gas wells;
high torque;
large bending loads;
sealing of the metal-to-metal threaded connection;
high resource
Tubing with high-strength threaded connection for hydraulic fracturing and technological work D 60-89 mm
Standard thread
step 2,54мм
High strength thread
step 3,175 мм
Design advantages:
increase in breaking tensile load by 20% by increasing the length and pitch of the thread;
distortion due to increased free entry of the thread into the coupling;
increase in the guaranteed operating time of a threaded connection for wear up to 25 trips;
reducing the cost of the pipe due to the use of smooth pipes instead of pipes with upset ends (an alternative to NKTV pipes)
