ASME B16.9 ASTM A420 WPL6 Carbon Steel Reducing Tee Pipe Fittings
Unequal Tees for Various Industries and Applications
Product Introduction:
ASME B16.9 Carbon Steel Reducing Tees are pipe fittings used to combine or divide fluids or gases
flowing through pipes with different diameters. These tees have
three openings, with two outlets that are of different sizes and
branch off at a 90-degree angle from the mainline.
ASME B16.9 Carbon Steel Reducing Tees are designed to connect pipes with different diameters, allowing
for a smooth transition in the flow of fluids or gases. The larger
outlet of the tee is typically connected to the mainline, while the
two smaller outlets are connected to the pipes of smaller diameter.
These fittings are commonly used in piping systems where there is a
need to merge or split flows between different pipe sizes. They
provide a convenient and efficient solution for accommodating
variations in pipe diameters and maintaining the desired flow
characteristics.
These Reducing Tees are manufactured in accordance with the B16.9 standard, which
specifies the dimensions, materials, and other requirements for
pipe fittings. This ensures that the tees meet industry standards
and can be reliably used in various piping applications.
Description of ASTM A420 WPL6:
ASTM A420 WPL6 is a grade of material specified in the ASTM A420 standard for
pipe fittings made of wrought carbon steel and alloy steel intended
for low-temperature service.
Composition: ASTM A420 WPL6 fittings are made from carbon steel or low-alloy steel with a specified
chemical composition that includes elements such as carbon,
manganese, phosphorus, sulfur, silicon, nickel, chromium,
molybdenum, and other alloying elements.
Mechanical Properties: The mechanical properties of ASTM A420 WPL6 fittings are designed to meet specific requirements for tensile strength,
yield strength, elongation, and impact toughness at low
temperatures. These properties ensure the fittings can withstand
the stresses and conditions encountered in low-temperature service
applications.
Low-Temperature Service: ASTM A420 WPL6 fittings are specifically intended for use in environments where low
temperatures are a consideration. They are suitable for
applications in industries such as oil and gas, petrochemical, and
cryogenic systems where the piping systems operate at temperatures
below ambient levels.
Impact Testing: ASTM A420 WPL6 fittings undergo impact testing at a specified temperature (typically
-45°C) to ensure they possess the necessary toughness and
resistance to brittle fracture under low-temperature conditions.
Weldability: ASTM A420 WPL6 fittings are weldable using common welding methods and techniques,
enabling them to be installed and integrated into piping systems
effectively.
Features of ASME B16.9 Carbon Steel Unequal Tees/Reducing Tees:
Flexibility in Design: ASME B16.9 Carbon Steel Unequal Tees allow for the connection of three pipes of varying diameters at a
90-degree angle. This offers flexibility in system design, allowing
for the branching or merging of flows between pipes with different
sizes. It enables the creation of complex piping configurations to
suit specific requirements.
Efficient Flow Distribution: ASME B16.9 Carbon Steel Unequal Tees provide efficient flow distribution by accommodating pipes of
different diameters. They help to reduce pressure drop and
turbulence in the system, ensuring smooth and uniform flow. This
leads to improved system performance and reduced energy
consumption.
Versatility in Application: ASME B16.9 Carbon Steel Unequal Tees can be used in a wide range of applications where the combination
or division of fluids or gases is required. They find utility in
industries such as oil and gas, petrochemical, water treatment,
HVAC, and many others.
Easy Installation: ASME B16.9 Carbon Steel Unequal Tees are designed for easy installation and connection to pipes using
standard methods such as welding, threading, or flanging. They are
readily available in the market and can be integrated into piping
systems with minimal effort.
High-Quality Standards: ASME B16.9 Carbon Steel Unequal Tees are manufactured in compliance with the B16.9 standard, ensuring
dimensional accuracy, material quality, and overall performance.
This guarantees that the tees meet industry standards and can be
relied upon for their durability and long service life.

Grades of ASTM A420 Unequal Tee/Reducing Tee:
ASTM A420 is indeed the standard specification for pipe fittings made of
carbon steel and alloy steel designed for low-temperature services.
Among the various grades specified under ASTM A420, WPL6 is the most commonly used material grade. In addition to Grade
WPL6, the standard also includes other grades such as WPL9, WPL3,
and WPL8, each with different impact test temperatures
corresponding to specific low-temperature service requirements:
- Grade WPL6: Impact test temperature at -45℃
- Grade WPL9: Impact test temperature at -75℃
- Grade WPL3: Impact test temperature at -100℃
- Grade WPL8: Impact test temperature at -195℃
These different grades with varying impact test temperatures allow
for the selection of the most suitable material based on the
specific low-temperature conditions in which the pipe fittings will
be operating. It is essential to choose the appropriate grade to
ensure that the fittings can withstand the required service
conditions and maintain their integrity and performance at low
temperatures.
Applications of ASME B16.9 Carbon Steel Reducing Tees:
Size Transition: ASME B16.9 Carbon Steel Reducing Tees allow for a smooth transition between pipes of different
diameters. They provide a convenient and efficient solution for
connecting pipes with varying sizes, ensuring proper flow and
minimizing pressure drop.
Branching or Diverting Flow: ASME B16.9 Carbon Steel Reducing Tees enable the branching or diverting of flow in a piping system. They
allow for the distribution of fluids or gases to multiple lines or
equipment, accommodating different flow requirements.
System Design Flexibility: By using ASME B16.9 Carbon Steel Reducing Tees, designers have more flexibility in designing piping systems. They
can easily accommodate changes in pipe size or adapt to specific
space constraints, optimizing the layout and functionality of the
system.
