Overview: The YJ340 production line consists of pre-tightening machine, bucking machine, auxiliary machine, and hydraulic unit & control cabinet; The production line automatically completes the coupling oiling, pre-ightening, screwing on-off, "J" value inspecting, and the QR code quality tracking system to achieve screwing on & off automatically and the informatization of pipe production management. |
Parameters & process requirement
Application: Ф140～Ф340（5 1/2″、7″、9 5/8″、10 3/4″、13 3/8″）Thickened and non thickened oil pipes and casings.
Applicable Length：8-12.5m.
Max. unit weight of pipe：1500KG.
Applicable connections: API (round & BTC)and Premium connections(with or without shoulder).
Applicable steel grade:Group 1 –Group4 & others.
Max.pre-tightening torque：500N .M
Max.screwing torque:68KN.M @ 20Mpa pressure.
Die marking: API standard.
“J “value tolerance: ≤±0.5mm
Auto-oiling into the coupling:can be adjusted to the coupling size.
Working speed:30-40 pipes/hour
Control method:manual,semi/full-Auto modes.
Noise gas consumption: less than 80 DBs
Torque control : The unit can be used for API and Premium connections(with or without shoulder), it can display the torque-turns graph, and record the torque & turns automatically, detect & analyze the inflection point of premium connection, judge the connection is qualified or not according to the J value and save the screwing graph.
Eight(8) torque control modes ,covering all connection types:
Torque /turns
Only torque
Only turns
Turns /torque
Torque /“J”value
“J”value/torque
“A”value/torque（BTC）
Premium connection
The screwing data can be saved as forms of daily, monthly production and quality reports
This software supports a quality tracking system and has the function of scanning and identifying the OR code on the pipe body. It corresponds to the connection parameters of the pipe and the corresponding input information such as the coupling number and coupling furnace batch number, and synchronizes the data to the corresponding database of the pipe number in the server
Auto-control & communication requirements
Siemens PLC as control system. LABVIEW human-computer interface, connect to upper PC with Ethernet and communication with the control room.So it can realize the observation, remote dialogue and fault diagnosis in the control room.
