When it comes to welding and joining materials precision flange and machine pays very
close attention to the details. All of Our welders are certified to ASME section IX and
we have hundreds of welding procedures qualified under ASME section IX to fit your
specific needs and technical requirements.
We acquire the highest quality consumable materials available and have strict
consumable storage and handling procedures. We offer a wide variety of welding
process including GMAW, FCAW, SAW, and GTAW welding. Our skilled welding operators
are ready to get your order processed today.
As seen in the photo, we often provide fitting modification and fitting fabrication
for our customers. If you have two 90° elbows and need them converted to 180° returns
or if you have two butt weld tees you need split and converted to butt weld crosses
we have the quality fabricators you need to get the job done.
Scraper bars are installed in butt weld tees to prevent the pipeline pig from flowing
into the outlet. This allows for pipelines to be cleaned and inspected. Without scraper
bar attachments the pig could create serious damage to piping, valves, and
instrumentation. When inquiring for scraper bar installation please provide the number
of bars and grade of material that you require.
A flanged fitting consist of a fitting (butt weld tee/ elbow/reducer/butt weld cross)
with flanges welded to the ends. You can provide us with the fittings and flanges or
we can supply the fittings and flanges. We then will weld the flanges to the fittings
and certify the welds with Ultrasonic or Radiographic testing.
Pipe spools come in many different configurations and orientations as seen in the
picture to the right. With drawings and specifications provided we can fabricate the
highest quality pipe spools that can be tested and certified in house.
As seen in this picture, we have a special consumable storage room that is climate
control. Consumables play a critical role in the quality of a weld. For example if
flux cored wire is not stored properly the flux center can absorb moisture (H20) and
can cause Hydrogen induced cracking in the weld metal. This is one reason that we
have very strict procedures when it comes to the storage and handling of our consumables.
The control of ferrite in austenitic welds is becoming more and more common this
is not an issue for Precision Flange & Machine. We have invested heavily in
developing special welding controls and procedures to control ferrite levels in
the weld metal of our products. We have built a special clean room for welding
when ferrite control is an issue.
