This is Turtle
If you want it to shine Smooth finish and looks pretty you use the 300
series
and if you don't care about it looking pretty you use 404 industrial
grade
Stainless Steel Pipe. 404 has a ruff finish and sometime off color in
gray
looking colors. You usely will paint the 404 to make it look pretty in
the
oil
industry. For the shinny smooth finish you pay dearly for it. years ago
it
sold
for about $90.00 for a 20 foot joint of 3.5" Sch. 40. It must have went
up
in
the last 15 years and could be up to $150.00 to $170.00 a 20 foot
joint.
These
prices was for Oil field work and not for a hardware store to sell. If
you
request the 300 series smooth and pretty this joint would run you maybe
$300.00
to $400.00. The oil Industry buys ruff ugly pipe and cheap and not
shinny
and
pretty.
When you say a joint of pipe. The slang words for this is a joint of
pipe
is any
length over 10 feet that you want to refer to it as talking about it.
All pipe like this is sold in 10 feet joints, 20 feet joints, and rolls
of
a
half miles. 10 feet and half mile rolls are rare and most everything is
sold in
20 feet joints. The half mile rolls are used on pipe line laying from
big
spools
off Catapillar skid and can lay a 1/2 mile of pipe before they have to
make a
weld. A bought the only way to transport it is by ships or railroad for
the
spool is about 30 feet high and 20 feet wide. It is also used a lot in
the
Gulf
of Mexico where they can supply it to the pipe laying equipment and not
have a
transporting problem. Now I have been told they have longer spools for
the
Gulf
work and can get 2 or 3 miles on spools to lay in the Gulf.
The public buys the 300 series and the industrial works buys the 400
and
600
series for their use. Also the Industrial people buy sometimes 50 to
100
miles
of pipe and they get discounts out of this world.

Hey Turtle!
Things in the oil industry must be far different from those in the
manufacturing industries. There are no 400 series pipe types listed
(Jorgensen stock list, 1988) which doesn't surprise me in the least.
400
series stainless is a straight chromium stainless (no nickel), unlike
the
300 series. The 400 series is heat treatable, which could present
particular problems when (field) welded.
This is Turtle.
The 404 stuff is a lot of times put together with what they call a Zapota
Lock
joint. You don't weld it but a big machine will push one end into the
other with
a socket joint in it and there is a ring that snaps into place. It take
about
20,000 + pound of pressure to push the pipe into the other. When it comes
to the
ring it will make a noise like a 22 rifle going off when it snaps into
place.
this might what ytou say is the story to use this Zapota Locking joints .
Pipe and tubing are available in 304, 316, 321 and 347 only, according
to
Jorgensen.
I can't help but wonder if the 404 designation pertains to oil field
jargon,
not to the alloy from which the pipe is made. Comments?
I use to work in the oil field and everytime it had the 404 or the 606 on
it. It
would say on the pipe : [ Inland Steel Pipe - SS-404 ] or 606. It may be
their
code or rating of the pipes and valves. This 404 stuff was very good for
Acid
plants where they flowed highly corrisive stuff through it. The Shell Oil
Refinery in Channel View , Texas used a lot of this stuff in their Battery
Acid
refining section.
Thanks for the explanation of "joint". Again, likely an oil field
term,
certainly nothing ever used where I worked, but then we didn't
specialize in
pipe, either.
Harold
You got me wondering about the 404 business .
TURTLE
Yep, me too! The 606, too. Neither of those terms show up in the stock
book. If you learn more, or I do, lets post it for those that have an
interest.
Be cool,
Harold
