Common questions about equal tee specifications, sizing, materials and applications.
An equal tee is used to create a 90-degree branch connection where the main run and branch have the same nominal pipe size. It allows three piping sections of equal nominal size to be connected.
An equal tee has the same nominal size at the run and branch outlets. A reducing tee has a smaller branch outlet than the main run and is used where a reduced-size branch connection is required.
Butt-weld equal tees are generally supplied according to applicable ASME B16.9 dimensional requirements. The material grade is specified separately according to the applicable ASTM material specification.
Ideally, provide the nominal pipe size, schedule or wall thickness, material grade, quantity and applicable standard. Project specifications, drawings or special requirements can also be included where applicable.
Yes. Equal tees can be included together with elbows, reducers, caps, flanges, gaskets, fasteners and other piping components in a single Bill of Materials. Rhevon can review the complete requirement and coordinate the applicable sourcing requirements.
Share the size, schedule, material, quantity and applicable specification. Mixed piping component requirements are also welcome.
Common questions about eccentric reducer specifications, orientation, sizing, materials and applications.
An eccentric reducer connects pipes of different nominal sizes while maintaining an offset centerline. Its geometry provides a flat reference side and can be selected where the piping layout requires an offset transition.
A concentric reducer maintains a common centerline between the larger and smaller pipe ends. An eccentric reducer has an offset centerline, creating a flat side that can be oriented according to the piping arrangement.
The terms describe how the flat side of the eccentric reducer is oriented when installed. The required orientation should be determined from the piping layout, drawings and applicable engineering requirements.
Eccentric reducers can be sourced in carbon steel, low-temperature carbon steel, alloy steel and stainless steel. Butt-weld dimensions are generally supplied to applicable ASME B16.9 requirements, with material specifications selected according to the project requirement.
Ideally, provide the larger NPS, smaller NPS, material grade, schedule or wall thickness, required orientation, quantity and applicable standard. Project drawings or additional technical requirements can also be provided where applicable.
Share the larger and smaller pipe sizes, schedule, material, orientation, quantity and applicable specification. Mixed piping component requirements are also welcome.
Common questions about concentric reducer specifications, sizing, materials and applications.
A concentric reducer connects pipes of different nominal sizes while maintaining a common centerline. It is used where a symmetrical transition between the larger and smaller pipe is suitable for the piping arrangement.
A concentric reducer maintains a common centerline between the two pipe ends, while an eccentric reducer has an offset centerline. The appropriate configuration depends on the piping layout, flow arrangement and installation requirements.
Butt-weld concentric reducers are generally supplied to applicable ASME B16.9 dimensional requirements, with the material specified separately according to the applicable ASTM material specification.
Ideally, provide the larger NPS, smaller NPS, material grade, schedule or wall thickness, quantity and applicable standard. Project specifications, service conditions or special requirements can also be included where applicable.
Yes. Concentric reducers can be included along with elbows, tees, caps, flanges, gaskets, fasteners and other piping components in a single Bill of Materials. Rhevon can review the complete requirement and coordinate sourcing accordingly.
