Chelpipe Prime premium threaded connections
ChelPipe Group supplies oil and gas pipes with ChelPipe Prime gas-tight threaded connections, ChelPipe’s own development.
Unique technology
The threaded connections are produced with unique technology and high-precision equipment at the Pervouralsk New Pipe Plant and facilities of other licensed third-party manufacturers.
The company also offers after-sales make-up support at wells.
Premium threaded connection
Sealing
The patented seal design ensures stable performance under any combined loads.
Strength
High compressive strength is achieved with an optimised buttress thread and a reduced gap between stabbing flanks on the nipple and coupling thread. ChelPipe Prime connections outperform TOP VAM and JFE BEAR competitors in terms of permissible loads.
Make-up
Easy and fast make-up thanks to a strong coarse-pitch thread and a steep taper angle for deep stabbing; a high maximum make-up torque.
Pipes with special properties
ChelPipe Group provides a wide range of tubing and casing pipes with special properties for applications under extreme conditions such as low temperatures or corrosive environments.

T100
Gas-tight tubing coupling connection with a patented cone-to-cone seal.
T100NV
Gas-tight tubing coupling connection with a patented cone-to-cone seal. Modification of T100 threaded connection compatible with VAGT / New Vam thread.
T230
High-tightness tubing coupling connection with a patented cone-to-cone seal.
C100
High-tightness casing coupling connection with a patented cone-to-cone seal.
C100HT
Gas-tight casing coupling connection with a patented cone-to-cone seal. It is a modification of C100 threaded connection with an increased maximum make-up torque.
C230
High-tightness casing coupling connection with a patented contoured seal. The innovative seal design combined with a buttress thread ensures high tightness of connection under combined loads. The design of the nipple nozzle ensures high radial stiffness guaranteeing tightness when extreme tension is present (even in the event of unlocking) and high pipe body yield strength.
