| The
Tool Joints can be supplied in Standard
or Extra Long in accordance with API Specification
7.
The Tool Joint Forgings
are turned, bored and faced prior to heat
treatment by the Quench and Temper process
to produce a uniform microstructure, high
ductility, and other mechanical properties
in accordance with API Specifications.
The heat treatment is done under controlled
atmosphere for consistent quality. The
hardness of every tool joint is checked
by Brinell Hardness Tester and recorded.
The tensile and impact properties are
verified by destructive testing of a tool
joint representing each process batch.
Every tool joint is subjected to wet magnetic
particle inspection, both transverse and
longitudinal, to insure the absence of
defects.
Threads are precision
machined on CNC lathes. All connections
are 100% inspected for thread parameters
and phosphatized either with Zinc or Manganese
for antigalling treatment and protected
with metal or composite thread protectors.
All the Test and Inspection results are
documented.
Any special Customer
requirements with respect to identification
and marking are adhered to and verified
at all stages of manufacturing and prior
to shipment.
Options available for
Tool Joints are Make and Break, Cold Rolling
of thread roots, and Hardfacing (SmoothX?/SuperSmoothX?/CASING
PLUS?/ ARNCO 200XT™/ARMACOR M™).
