stainless steel straight Tee,This T-shaped pipe fitting used in the plumbing tee system has one inlet and two outlets arranged at an angle of 90 degrees to the main pipe. This kind of fitting is used to connect the two pipes and make their flow direction as one. If all the three sides of this fitting are same in size, it is called equal tee, otherwise unequal tee.

Stainless steel is the abbreviation for stainless and acid resistant steel. Steel that is resistant to weak corrosive media such as air, steam, water, or has rust resistance is called stainless steel; And the steel grade that is resistant to chemical corrosion media (such as acid, alkali, salt, etc.) corrosion is called acid resistant steel.
The most common used material is SS304/304L, SS316/316L, DUPLEX SAF2507, SAF2205,

Q:Customer asked for butt weld fittings in A105:
A: Most common carbon steel buttweld fitting material is A234WPB. It
is equivalent to A105 flanges, however there is no such thing as an
A105 or A106 butt weld fitting. A106 Gr.B is for pipe grade. The
A234WPB fittings are made from A106GR.B pipes. A105 is a material
from Bar forged to be High pressure Fittings or Flange
Q: Customer requests “Normalized” butt weld fittings:
A: This is also a misconception since flanges are available in A105
and A105 N, where N stands for normalized.
However, there is no such thing as A234WPBN. Manufactures normalize
their butt weld fittings was considered that normalized heat
treating process was done, Espeically for the elbows and Tees
Customer needing “normalized” butt weld fittings should request
WPL6 fittings which are high yield and are normalized as a standard
procedure.
Q: Customer forgets to mention pipe schedule:
A: Buttweld fittings are sold as per pipe size but pipe schedule must
be specified to match the ID of the fitting to the ID of the pipe.
If no schedule is mentioned, we will assume a standard wall is
requested.
Q: Customer forgets to mention welded or seamless butt weld fitting:
A: Butt weld fittings are available in both welded and seamless
configuration. A seamless butt weld carbon steel or stainless steel
fitting is made of seamless pipe and is generally more expensive.
Seamless pipe fittings are NOT common in sizes bigger than 12”.
Welded pipe fittings are made of ERW welded carbon steel or
stainless steel pipe. They are available in sizes ½” to 72” and are
more affordable than seamless fittings.
Q: What does Short Radius (SR) or Long Radius (LR) means?
A: You will often hear SR45 elbow or LR45 elbow. The 45 or 90 refers
to the angle of the bend for buttweld fitting to change the
direction of flow.
A long radius elbow (LR 90 Elbow or LR 45 elbow) will have a pipe
bend that will be 1.5 times the size of the pipe. So, a 6 inch LR
90 has bending radius that is 1.5 x nominal pipe size.
A short radius elbow (SR45 or SR90) has a pipe bend that is equal
to the size of the fitting, so a 6” SR 45 has a bending radius that
is 6” nominal pipe size.
Q: What is a 3R or 3D elbow pipe fitting?
A: First, the terms 3R or 3D are used synonymously. A 3R butt weld
elbow has a bending radius that is 3 times the nominal pipe size. A
3R elbow is equal to 3D Elbows
