DRILL PIPE PRODUCTION LINE:
The production line for the processing and production of oil
drilling pipe, is mainly divided into three steps, by using the
upsetting machine, Intermediate frequency quenching and tempering
machines, pipe threading lathes and some other machines.
1. Our products have good rigidity.
2. 400T upsetting force can meet all kinds of requirements of drill
pipe, oil pipe.
3. 256mm cavity can produce all products of oil pipe, drill pipe,
4. The range of process diameter that can be processed: 50mm-127mm.
5. Achieve the production automation.
STEP1: Hydraulic upsetting machine:
Hydraulic upsetting machine is widely used in oilfield,
construction, bridge and other industries, is the preferred
equipment to carry out large quantities, high precision upsetting
forging production, which is very suitable for round steel, steel
pipe, drill pipe, sucker rod, oil pipe and other long rod forging
Upsetting machine structural design is more ingenious, so that
equipment is more reliable; automatic nesting auxiliary machine
design concept is particularly advanced, the organization can
accurately and timely delivery of materials to the designated
|Punching speed||mm/s||≥ 157||≥190|
|Upper and lower die opening degree||mm||200||180|
STEP2: Intermediate frequency quenching and tempering production line :
TZX series intermediate frequency quenching and tempering
production line can complete various sucker rod, oil pipe, drill
pipe, drill collar, tubing and steel rod heat treatment processing.
It adopts the high strength bed design, have a variety of
configuration and can be chosen by the customer. The fully
automatic feeding device realizes the unmanned operation of the
whole production line, which greatly reduces the labor cost.

|Cooling water flow||t/h||100||150|
|Intermediate frequency (IF) power||KW||500||1000|
|Ultrasonic frequency power||KW||80+80||120+120|
STEP3:Pipe threading lathe :
QK series pipe threading lathe is also called oil country lathe,
big bore lathe and hollow spindle lathe are economical CNC
horizontal lathe, which are not only suitable for oil pipe thread
turning, but also widely used in all works of life such as
automotive, petroleum, military and other mechanical processing.
The lathe has the advantages of high efficiency, low scrap rate,
good consistency, etc.
