We perform constant inspection on thread cutting and rethreading on oilfield tubular and all down-hole tools. Which is a most critical operation in the making of quality products Lead?
Taper, Thread profile, Depth of thread and Gauge stand –off are all constantly monitored to guarantee tolerances and uniformity.

Then all connection are chemically treated to prevent galling thread roots are cold worked to provide longer fatigue life.

All the incoming material (tubular) threads are visually and dimensionally inspected by Quality control before machining the job.

After machining the parts are dimensionally and functionally inspected by Quality control and document maintained as per our procedure


Even the thread cutting “INSERTS” are examined 100% by the use of an Optical comparator to assure proper thread form and depth.

Gauges used on each production order are examined and re-qualified to the master set of Gauges after each order.


We have most sophisticated equipment. Its also available to our customers for any additional testing they wish to perform, such like that,

  • Dye penetrant test,
  • Ultrasonic,
